The previous figure applies to LogBooks, DaqBook/100/200 Series devices, and ISA-type DaqBoards. As will be seen elsewhere in this document, some devices do not include all three connectors, i.e., P1, P2, and P3. Connecting DBKs to Daq PC-Cards The Daq PC-Card is only intended for connections to a P1 connector of a single “passive” DBK card or module. A passive DBK card or module is one that provides a desired connectivity (such as BNCs or screw terminals), but performs no signal conditioning.
Connecting DBKs to DaqBoard/2000 Series Boards DaqBoard/2000 Series and cPCI DaqBoard/2000 Series boards have 100-pin connectors designated as P4. The 100 pins correlate to various pins on P1, P2, and P3 DB37 connectors.* Connectivity in the system is as follows (see figure). • Both the DaqBoard/2000 and /2000c Series board connect to a CA-195 cable. The cable has two, 100-pin, P4 connectors. • The CA-195 connects to a DBK200 Series adapter board or adapter module for 100-pin to 37-pin adaptations, e.g.
Connecting DBKs to DaqBook/2000 Series Devices Several products make use of the DaqBook/2000 nomenclature. However, they do not all offer the same connection options. Refer to pinouts for the specific devices, as needed. Product Connects to DBK Expansions via … DaqBook/2001 and /2005 37-pin connectors P1, P2, and P3. There is no P4. DaqBook/2020 37-pin connectors P1 and P2. There is no P3 or P4. DaqOEM/2001 and /2005 40-pin headers (JP1, JP2, and JP3). There is no P4.
Connecting DBKs to a DaqBook/2000 Series Device via P1, P2, and/or P3 The DBKs do not connect directly to the port, but through a CA-37-x ribbon cable, where “x” indicates the number of expansion devices that can be connected. For example, a CA-37-3 cable includes a 37-pin mating connector to interface with the DaqBook/2000 Series DB37 connector (P1, P2, P3); it also includes three additional DB37 connectors. These provide a means of adding three DBKs to one port.
Connecting DBKs to a DaqBook/2000 “AEX” Device via P4 Every DaqBook/2000 “AEX” device has a 100-pin connector designated as P4. The P4 pins correlate to various pins on P1, P2, and P3. The P4 connector on a DaqBook/2000 “AEX” device shares signal connections with the P1, P2, and P3 connectors. P4 offers no additional I/O. Connecting a DBK200 Series Option to P4 via a CA-195 cable distances the P1, P2, P3 connection from the DaqBook/2000 “AEX” device. It does not provide any new signal I/O.
P4 connectivity for DaqBook/2000 “AEX” devices is as follows: • One end of a CA-195 cable connects to the DaqBook/2000 “AEX” device’s 100-pin P4 connector. Note that the CA-195 cable has two P4 connectors. • The other end of the CA-195 cable connects to a DBK200 Series adapter board [or adapter module] for 100-pin to 37-pin adaptations, e.g., P4-to-P1, P2, P3; but not necessarily all three.

Analog Signal Conditioning DBKs The DBKs that are used for analog signal conditioning attach to transducers and condition their outputs into analog voltages. An A/D converter, located in the primary acquisition device, measures the analog voltages. There are many signal-conditioning solutions available (and more are in development). Note that DBK high-capacity modules require more circuitry than can fit on a compact card.
Expansion and Terminal Panel Connection DBKs The following DBKs offer provide various expansion and connection options. The stackable 3-slot DBK10 low-profile enclosure can be used for up to three DBKs. If a system has more than 3 DBKs, the 10-slot DBK41 can be used. Several DBK41s can be daisy-chained to accommodate many DBKs in one system.
Power Supply DBKs Power supply type DBKs are typically used in laboratory, automotive, and field applications. Input power can come from any +10 to +20 VDC source, or from an AC source by using an appropriately rated AC-toDC adapter. The DBK30A rechargeable power supply can power DBK modules where AC mains are not available (the DBK30A outputs 28 V for powering transducers). For a large number of DBK cards, the DBK32A or DBK33 can be installed into an expansion slot.
4. When configuring your LogBook or Daq device(s) consider the following: • LogBook calibration is typically performed automatically through LogView software; however, some DBKs may require manual calibration. • The DaqBook/100 Series and DaqBook/200 Series devices, and DaqBoards (ISA type) have internal jumpers and switches that you must set manually to match your application. • Some DaqBook/100 Series and DaqBook/200 Series models are partially configured in software.
Power Supplies and Power Connectors Power supplies convert the raw power they receive into a lower DC voltage and/or current for use by devices with various power demands. Many of the power supplies that are used to power data acquisition equipment are of the switching-mode type. These devices provide a regulated output whether the power supply’s input is, for example, 60 Hz, 120 VAC as in the United States or, 50 Hz, 220 VAC as found in European countries.
An Introduction to Power-Related DBKs The power-related DBK options are the DBK30A, DBK32A, DBK33, DBK34, and DBK34A. From the standpoint of providing reliable power, these DBKs have proven convenient in laboratory, automotive, and field applications. Input power for these devices can come from any 10 to 20 VDC source, or from an AC source via an appropriate AC-to-DC adapter. A brief synopsis of the DBK power options follows. Refer to the respective document modules for complete information.
Power Requirements The improper use of power can cause system damage. The following terms are important in regard to understanding your system’s power needs. • Supply power for signal conditioning type DBKs comes from a primary acquisition device, such as a DaqBook/2000 Series device or LogBook, or from a power card or module. If needed, the DBK32A or DBK33 can provide additional power to meet DBK power demands.
DaqBook/2000 Series Devices If using power from AC mains (through adapter), you need not worry about Daq device power use. If using battery-power, you can compute operational endurance from the battery’s watt×hr rating and power tables. DaqBook/2000 Series devices use no power from the PC, but do require DC voltage from an AC-to-DC adapter with a supply range of +10 VDC to +30 VDC, or another suitable DC source. Various AC adapter models support power grids of USA, Europe, Japan, and Asia.
Calculating Your System’s Power Needs Use the chart below and the worktable on the next page to ensure your system will have sufficient power. If the load (calculated in the worktable) exceeds available power (from the chart at the right), you must add a power card or a module such as a DBK32A or DBK33.

Input Isolation Three benefits of input isolation are circuit protection, noise reduction, and the rejection of high common mode voltage. • Circuit protection. Input isolation separates the signal source from circuits that may be damaged by the signal. (Voltages higher than about 10 V can distort data or damage chips used in data acquisition.) High-voltage signals or signals with high-voltage spikes should therefore be isolated.
Differential Circuit with Shunt-reference A way around this problem is to use a differential measurement for each shunt, with the instrument common connected to the supply common. Each input channel will measure the shunt voltage and will reject any voltage in the common wire (common-mode rejection). Differential Mode, Floating (Isolated from Ground) Floating-differential measurements are made when low-level signals must be measured in the presence of high levels of common-mode noise (e.g.
WRONG CORRECT High Input Signal High Input Signal Differential Amplifier Shield Grounding Wire Shield Grounding Wire Low Input Signal Differential Amplifier Low Input Signal Ground loop caused by current flow. Potential difference and no path for current flow. No Noise-Inducing Ground Loop Noise-Inducing Ground Loop Aside from eliminating noise-inducing ground loops, the use of bias resistors should also be considered with isolated signal sources.
System Noise Electrical noise can present problems even with good equipment; thus, controlling noise is imperative. Some techniques avoid or prevent noise sources from entering the system; other techniques remove noise from the signal. Laboratory and industrial environments often have multiple sources of electrical noise. An AC power line is a source of 50/60 Hz noise. Heavy equipment (air conditioners, elevators, pumps, etc.) can be a source of noise, particularly when turned on and off.
Crosstalk Crosstalk is a type of noise related to source impedance and capacitance, in which signals from one channel leak into an adjacent channel, resulting in interference or signal distortion. The impact of source impedance and stray capacitance can be estimated by using the following equation. T = RC Where T is the time constant, R is the source impedance, and C is the stray capacitance. High source (transducer) impedance can be a problem in multiplexed A/D systems like the DBK12, DBK13, DBK15.
Channel Control and Expansion In a Daq device or LogBook system, DBK expansion cards and modules can increase the number of analog input channels from 16 base channels to 256 input channels (16 × 16). The configuration will vary depending on the DBK’s channel capacity; for example, four 4-channel DBKs or two 8-channel DBKs can share the same base channel.
The following table details how expansion channels are numbered in DaqView and LogView. API Channels are used in Daq devices by third party programs. Note that API Channels are not used in LogBook systems.

Ensures that channels are scanned at exactly 10 µs intervals.
Scan Group All channels within scan group are measured at 10 µs/channel. Time Scan Period (Immediate to 10 hours) 10 µs Time Channel #2 #4 #7 #2 Gain x1 x8 x8 x2 Digital Input #18 x100 #19 x10 #16 x1000 Scan Rate Most sampling of analog signals occurs on the timebase of the LogBook or the Daq device clock. The scan period is the time duration between successive scans.
• • The post-trigger scan count specifies the number of scans to be collected after the trigger point. After the trigger, the post-trigger scans will be collected as programmed and then the system will disarm itself. The trigger source can be a software command, an external TTL input, etc. An analog input channel on reaching a specified voltage level can be used to trigger the system.
The previous figure can be used to understand how SSH is used in the DBK17 SSH Card. The process is as follows: • Input signals pass through an instrumentation amplifier and into a sample-and-hold stage. • When the sample enable line goes high, each channel’s sample-and-hold stage will “freeze” the current analog value. The values for all channels are separately “latched” within 50 ns of each other. • The signals are held in a stable condition, while the multiplexer switches through all channels.
Download instructions for loading the constants into DaqView were included with the DBK19. The constants will improve the accuracy of each DBK19 channel when amplifying the thermocouple's millivolt output, which is read by the DaqBook.
Calculation of Scale and Offset Using the above information, calculate the values of scale (m) and offset (b) that will compensate for the measurement errors (RA1 and RA2). This is possible because the correct and actual readings are related by the (mx + b) equations: RC1 = m(RA1) + b and RC2 = m(RA2) + b Substituting in the values noted in the above calibration process: RC1 = m(RA1) + b 0 = m(2.1) + b RC2 = m(RA2) + b 100 = m(104) + b Solving for “m” results in: 100 = m(104 -2.1) m = 100/(104-2.1) = 0.
One Known Temperature Environment Suppose that you only have one known temperature environment, such as an ice bath. In this case only one parameter in the “mx + b” equation can be determined for system calibration. This is called single-point calibration. Since this is normally the largest source of error, single-point calibration is used to correct the offset. Using the same information as in the first example, and supposing that the only actual reading available is called RA: RA = 2.
CE Standards and Directives The electromagnetic compatibility (EMC) directives specify two basic requirements: • The device must not interfere with radio or telecommunications. • The device must be immune from electromagnetic interference from RF transmitters etc. The standards are published in the Official Journal of European Union under direction of CENELEC (European Committee for Electrotechnical Standardization).
The specific safety conditions for CE compliance vary by product; but general safety conditions include: • The operator must observe all safety cautions and operating conditions specified in the documentation for all hardware used. • The host computer and all connected equipment must be CE compliant. • All power must be off to the device and externally connected equipment before internal access to the device is permitted.
DBK41/CE The DBK41/CE includes 3 variations of EMI shield plates that attach to the DBK41 enclosure. Besides acting as an electrical safety barrier, these shields reduce electromagnetic interference (EMI). Note: The CE kit is included with the DBK41/CE. It can be purchased as an optional accessory for use with DBK41. BNC Connectors for CE Compliance Exposed BNC connectors can receive static charges, which can enter the board’s circuitry, resulting in ESD damage.

Setting Up Analog DBKs If you have not already done so, review the applicable individual DBK section to ensure that the DBK option is physically set as desired. Note that certain DBKs do not require configuration. Understand your DBK’s physical configuration before attempting to set the device in DaqView’s Hardware Configuration window. For example, if you were configuring a DBK45 in DaqView, you would need to know the physical setup of rotary switch SW6 to properly set the address.
The DBKs typically have a channel address set physically on the device, by either a switch or a header. The channel designated in software must agree with the hardware setting. Thus, in step 2 below, Channel 0 will only be used to select a specific DBK when that DBK is physically set for Channel 0. Refer to the specific DBK section for more information, if needed. 2.
Setting Up Digital DBKs If you have not already done so, review the applicable DBK section to ensure that the DBK option is physically set as desired. Note that certain DBKs do not require hardware or software configuration. Reference Note: If you need to go beyond the basic software setup information that follows, refer to the DaqView documentation. Note that you can access PDF versions of documents from the data acquisition CD by using the button on the CD’s intro page.

Many customers have solved problems without factory assistance. Reference Note: A list of API error codes appears in the Programmer’s Manual included on your CD-ROM. Note that API does not apply to LogBook.
8. Software setup. Make sure the device selected in software matches the hardware being used. Verify that setup parameters are correct for your application and attached DBK cards and modules. 9. Power management. The POWER.EXE power management program that is used by some notebook computers is known to affect proper operation of the parallel and PCMCIA ports. If you are having such trouble, remove the line loading this program from your AUTOEXEC.BAT file. 10. Device drivers.
Windows NT 1. Check the power supply to make sure power is applied. 2. Check the parallel port cable for tight connections. Try all of the protocols listed in the Daq device Configuration control panel. The parallel port might have a communication protocol other than standard or normal mode. 3. If you still have not established communications, go to Control Panel, Devices, Hardware Profiles, Parallel Port and verify the parallel port drivers are installed.
Q: I can read analog inputs at the primary Daq device, but my ISA-type DBK option card doesn’t work. What could be wrong? A: The analog DBK cards require power to operate. This power can be provided by the DaqBook or ISAtype DaqBoard (via JP1), DBK32A, or a DBK33. The following voltages [with respect to P1’s pin 7] must be present to power up analog DBK option cards: • • • +15 volts on P1, pin 21 -15 volts on P1, pin 2 +5 volts on P1, pin 1 Note: Daq PC Cards do not have power available.
Q: The DBK4 seems to kill my system. When the DBK4 is removed, the system functions properly. Does this imply that the DBK4 is defective? A: More often than not this indicates a lack of available power. The most common symptom of low power is a "dead" unit. Failure to provide adequate power can damage one or more components in your system, but more frequently, the system simply won’t work.
Q: How do I calculate the total amount of power needed for all my DBK options? A: You can calculate your power needs with the tables in Power Management, in the DBK Basics section located near the front of this manual. Q: The CA-134 cable does not work with my Daq PC-Card. Why not? A: Daq PC-Cards Daq/112B and Daq/216B that have a serial number equal to or greater than S/N 151044 use cable CA-134. This cable’s latching connector does not work with the older PC-cards.

DBK4 Power Notice DaqBook/100 cannot provide adequate power for a DBK4. For information regarding the use of power cards and power modules see Power Requirements in the DBK Basics section near the front of this manual. Power-Requirement Worktable CAUTION Quantity x milli-Watts = power required Excessive power consumption can cause equipment damage. Calculate system power requirements before adding a DBK4 to the system.
Hardware Setup If using a DaqBook/200, DaqBook/216, DaqBoard/200A, or DaqBoard/216A that has a serial number of 103350 or earlier, you must contact the factory for a hardware upgrade (EO-1911) before using the DBK4. Software calibration for each DBK4 requires a set of unique constants supplied on a diskette identified by a serial number matching the DBK4 card. To install these constants, follow instructions on the “readme” file included on the calibration disk.
Signal Coupling (JP2 & JP3) The figure shows jumper settings for selecting AC coupling, 10 Hz or 0.1 Hz High Pass Filter (HPF), or DC coupling. Signal coupling is application specific. 10 Hz HPF suits most applications for acceleration measurements on “light” structures. When performing seismic measurements (or measurements on “massive" structures) the 0.1 Hz HPF rejects the DC bias component while preserving the low-frequency signals. JP2 Default: 0.1 Hz JP3 Default: 0.
Current Level (Transducer Biasing) (JP6) Current level is not channel-specific. The level selected applies to both channels. The figure shows the JP6 jumper settings for current level. Most transducers operate with either 2 or 4 mA of bias current. However, biasing at 4 mA allows the transducer to drive longer cables. Reference Note: For more information, refer to the Cable Driving section of the DBK4 Accelerometer Tutorial.
The DBK4’s sub-channel address is selected using switches s5 - s7 of DIP switch SW1 (located above and to the right of JP1). As a 2-channel card, 3 switches are used to select 8 sub-channel addresses. Therefore, it is possible for each main channel to use up to 8 DBK4s. The figure below shows 16 switch settings for the main channel and 8 settings for the sub-channel (card) selection. Card Connections The DBK4 connects to the LogBook’s or Daq device’s P1 port or a P1 port on a DBK Expansion Module.
DaqBook/100 Series & /200 Series and DaqBoard [ISA type] Configuration Several setup steps of DaqBooks /100 Series & /200 Series devices and DaqBoards [ISA type] are required to use DBK4 cards in a system. Note that the Daq PC-Card is configured in software; it cannot supply power to DBKs. 1. If not using auxiliary power, place the JP1 jumper in the expanded analog mode (Analog Option Card Use). In this mode jumpers are at JP1’s –15 V and +15 V positions.
Signal Coupling The input can be configured via jumpers to maximize the usable signal spectrum. The DBK4 provides two, 1-pole High-Pass Filters (HPF) and one DC path. The HPF can be set to 0.1 Hz, 3 dB cut-off frequency. In this case, the system frequency response is limited by the source characteristics. The HPF can also be set to 10 Hz, 3-dB cut off frequency, for high-frequency measurements.
Software Controls Power management, the PGA, and the low-pass filter’s cut-off frequency are all software controllable. These parameters are sent via the external address bus in the P1 connector to the DBK4. The microcontroller decodes the configuration message, sets the PGA and filter controls, and illuminates the onboard LED. However, if transmission errors are detected, the micro-controller flashes the LED and ignores the message. The error is cleared when an error-free message is received.

Accelerometer Tutorial This accelerometer tutorial covers the following topics. Page numbers refer to DBK4 document module pages. What is a Piezoelectric Accelerometer?......11 Accelerometer Specification Parameters......11 Physical Setup......13 Electrical Grounding......14 Practical Limitations...... 15 Cable-Connector Handling Precautions......15 Cable Driving......
Sensitivity The sensitivity of an accelerometer is defined as its output voltage per unit input of motion. The unit of motion used is the “g”. One “g” is equal to the gravitational acceleration at the Earth’s surface, which is 32.2 ft/(sec)(sec) or 981 cm/(sec)(sec). The output is usually specified in millivolts per “g” (mV/g). Sensitivity is usually specified under defined conditions (frequency, testing levels, and temperature), for example: 100 mV/g at a frequency of 100 Hz, level +1 g, at 72°F.
This quasi-static effect produces a low-frequency voltage input to the MOSFET amplifier. This voltage is usually well below the low-frequency corner, but the effect can reduce the peak clipping level and cause loss of data. This effect does not affect the accelerometer’s basic sensitivity or the data unless the thermal shift in the operation bias level results in clipping. Where drastic thermal shifts are expected, use 12 V bias models. The effect’s severity is related to the mass of the accelerometer.
Removal of Adhesive Accelerometers Many accelerometers and adhesive adapters have been damaged by improper removal. A safe removal method is to torque the accelerometer or its adapter with a wrench using the flats provided. Adhesives are generally weakest in the shear mode and will yield under steady torque. Accelerometer Mounting CAUTION Never strike an accelerometer to remove it. The trauma will likely damage the accelerometer and affect calibration.
Practical Limitations Mass Loading The accelerometer mass should be less than 10% of the rigidly-coupled mass of the test object. The test object should be rigid at the mounting point, such as a bearing housing rather than a sheet metal cover. Upper Frequency Response Piezoelectric accelerometers will attenuate below the low-frequency 3-dB point, but they will amplify at or near their resonant frequency.
Cable Driving Operation over long cables is a concern with all types of sensors. Concerns involve cost, frequency response, noise, ground loops, and distortion caused by insufficient current available to drive the cable capacitance. Coupling a short (e.g., 1m) adapter cable from the accelerometer to a long, low-cost cable like RG-58U or RG-62U with BNC connectors can reduce the cost of long cables.

Reference Notes: o Chapter 2 includes pinouts for P1, P2, P3, and P4. Refer to pinouts applicable to your system, as needed. o In regard to calculating system power requirements refer to DBK Basics located near the front of this manual.
The 4 channels are optically isolated from the Daq Device and from each other. Isolation allows the loop voltages to float beyond the Daq Device’s common mode range. An externally powered loop allows the DBK5 to continue to modulate the loop current in the event of a fault or power loss in the Daq Device. If the loop is powered-up before the Daq Device, the DBK5 will maintain the loop current at 4 mA. After a fault, the DBK5 will maintain the loop current at the last level set.
Card Connection Current-loop connections are provided via dual screw terminal connections. The + and - loop connections are shown in the figure. Once all connections are in place, secure wires to the board at captive areas at the end of the board. Nylon tie wraps (not included) work well for this purpose. (1) An external loop-voltage supply must be provided.
CAUTION When using the SSH output, do not use an external voltage reference for DAC1. Applying an external voltage reference for DAC1, when using the SSH output, will result in equipment damage due to a conflict on P1, pin #26. 2. Place the JP2 jumper in the SSH position (see above CAUTION). 3. For DaqBook/100, DaqBook/112 and DaqBook/120 only, place the JP4 jumper in single-ended mode. DaqBook/2000 Series & DaqBoard/2000 Series No jumper configurations are required for these /2000 series devices.

Overview The DBK7 can be used for diverse frequency-monitoring applications. Typical uses include measuring the flow of liquids with a flowmeter and measuring rotation (rpm) with a shaft encoder. The monitored process must generate a series of electrical pulses whose frequency is related to the desired variable. Features of the DBK7 include: • Inputs can be analog (high or low level) or digital. • Each channel has a programmable frequency range.
Card Configuration Several jumpers and one switch must be set on the DBK7 card to match both the system setup and the signal-conditioning requirements. This section describes a typical configuration. The following table indicates the factory default settings of each jumper. The below figure shows the location of the jumpers and DIP-switch (S1). Factory Defaults for DBK7 On-board Jumpers Configuration Jumpers • • • Up to 4 cards can share the same J1 channel.
Channel and Card Selection Configuration (J1 and S1) Up to 4 DBK7 cards can connect to a single main channel. Thus, a 16-channel LogBook or Daq device can connect to 64 DBK7 cards. Since each card has 4 input channels, a fully populated system can use 256 input sensors. To keep these inputs organized, the card is configured by physically setting a jumper (J1) and a DIP switch (S1). • J1 is a 24-pin (3×8) header requiring two pins in a row to be connected. Up to 4 cards can share the same channel.
DBK7 Channel Configuration Note: Each of the 16 main Daq device channels can support 4 DBK7 cards; and each DBK7 card can support 4 analog channels. Both J1 and S1 (3-6) select the main channel (they must match). S1 (12) selects the card. Every card must have a unique address of channel and card. DBK Option Cards and Modules 879895 DBK7, pg.
Input Signal Conditioning Configuration Hardware settings affect 3 aspects of signal conditioning: • Input circuit selection: analog or digital • Attenuation selection • Low-pass filter selection. Input Circuit Selection Each input channel can be set for the analog or digital circuit. Two jumpers must be set for each channel. Select the input circuit for each input channel as follows: 1. Determine the best circuit type for each channel.
4. Verify the jumper position for each input channel. - JP1 for channel 0 JP21 for channel 1 JP41 for channel 2 JP61 for channel 3 Low-Pass Filter Selection (Analog Input Circuit Only) The low-pass filter removes high-frequency noise that could otherwise fool the DBK7 into detecting a higher frequency. To set the low-pass filter: 1. Determine the highest frequency you expect to measure on each input channel. 2.
3. Connect the other end of the cable to the P1 port of the LogBook or Daq device. For multiple DBK7 cards, use a CA-37-x (or CA-131-x) cable to daisy-chain several cards or an expansion module. For example, three DBK7s (or 2 DBK7s and an expansion module) can be connected to a LogBook or a Daq device with a CA-37-3. 4. For multiple cards from a Daq PC-Card, cable CA-134 must first connect to an expansion module (a CDK10 or a DBK41 with a DBK33 power card) then through a CA-37-x to the DBK7s.
2. Place the JP2 jumper in the SSH position (See previous CAUTION). 3. For DaqBook/100, /112 and /120 only, place JP3 jumpers in bipolar mode. 4. For DaqBook/100, /112 and /120 only, place JP4 jumpers in single-ended mode. DaqBook/2000 Series & DaqBoard/2000 Series No jumper configurations are required for these /2000 series devices. Software Setup Reference Notes: o DaqView users - Refer to chapter 2, DBK Setup in DaqView. o LogView users - Refer to the chapter 3, DBK Setup in LogView.
The following graph shows typical sine-wave sensitivity in peak-to-peak voltage vs frequency. Six combinations of attenuation (on/off) and low-pass filtering (30 Hz, 300 Hz, and 100 kHz) are graphed. Digital Input Signal Conditioning The equivalent digital input circuit is shown in the figure. The input signal may range from -15 to +15 V. Higher voltages may damage the DBK7. When the input circuit jumpers are set for digital, the outside (shield) conductor of the BNC connector connects directly to ground.
Edge Selection The DBK7 determines the frequency by measuring the time between successive rising or falling edges of the input signal. Which edge is electrically cleaner depends on the application and related components. If rising edges are used, the edge-selection circuit does not modify the signal. If falling edges are used, the circuit inverts the signal so falling edges appear as rising edges to the subsequent circuits. Through software, each channel can be independently set for rising- or falling-edge.
The following equation determines the time interval needed to measure a frequency: Minimum Measurement Period (sec) = (4096 x 0.5 µs) [Fmax/(Fmax - Fmin)] In this equation: 4096 derives from 12-bit precision; 0.5 µs is the resolution of the DBK7’s timing circuits; and Fmax / (Fmax - Fmin) is the ratio the measurement time must be increased to achieve 12-bit accuracy over the selected range.

Refer to pinouts applicable to your system, as needed.
Each DBK8 channel has 3 user-set voltage ranges: ±10 V, ±50 V, and ±100 V. The ranges are selected by the placement of shunt jumpers on pin headers for each channel. While the channel-to-channel resistance is 10 MΩ, there is no other inherent isolation between the channels. The common of the host computer has a direct connection to the LogBook or the Daq Device analog common. Either side of any input channel is 5 MΩ from analog common. The DBK8 has 3 attenuation factors.
DaqBook/100 Series & /200 Series and DaqBoard [ISA type] Configuration Use of the DBK8 expansion card with DaqBooks/100 Series & /200 Series devices and DaqBoards [ISA type] requires 3 jumper settings. 1.

Lower Channel Upper Channel V0Adj (Note 1) Source (+) Source (-) Excitation (+) Excitation Regulator Sensing (+) Bridge (+) 1 2 BCR Bridge (-) Sensing (-) Excitation (-) 2 These indicated lines connect to Source (+) and Source (-) lines of the Lower Channel Circuit. BCR stands for Bridge-Completion Resistors.
Connections are provided for Kelvin-type excitation. The excitation regulators stabilize the voltage at the points connected to the on-board sampling dividers. Unless you run separate sense leads to the excitation terminals of the strain gage, the voltage regulation is most accurate at the terminal blocks on the DBK16. In a Kelvin-type connection, six wires run to a 4-element strain gage, and the excitation regulation is optimized at the strain gage rather than at the terminal blocks.
Half Bridge, ( ∆R1↓ and ∆R2↑) ⇒ ∆EOUT↑ ) Resistor Configuration for DBK16 The half bridge configuration makes use of two elements of the strain gage. When using a half bridge external strain gage (two of four elements), the following applies to the DBK16 on board resistor configuration: Upper Channel – R10 and R13 are to be installed. Lower Channel – R22 and R25 are to be installed. Note that other Half Bridge scenarios exist.
3-Wire, Quarter-Bridge, Positive ( ∆R↓⇒ ∆EOUT↑) for DBK16 The quarter-bridge configuration makes use of one element of the strain gage. The three-wire, quarter-bridge can be configured as “positive” or “negative.” The above figure represents the positive (plus) configuration. In this setup, the magnitude of voltage out is inversely proportional to the change in resistance ( ∆R↓⇒ ∆EOUT↑).
The user-supplied excitation source should provide adequate current levels for all the DBK16s that are powered. The minimum current required for the user-supplied excitation source for each transducer (2 per DBK16) is: IMIN = Excitation voltage/R + 5 mA (where R = the resistance of 1 element in the bridge circuit) The user-supplied excitation source must be 12 to 15 VDC and connected with the proper polarity. Enhanced DBK16 cards contain two additional jumpers (JP6 and JP7).
DBK16 Board Layout AC Coupling, DC Coupling, and Low-Pass Filter Options Headers on the board accommodate the coupling and low-pass filter options and the output channel selection (see above figure). Resistors can be removed to lower filter gain from ×2 to ×1. A filter frequency determining resistor network can be inserted into an IC socket. The AC or DC coupling choice (on each channel) is set by the presence or absence of a shunt jumper on a two-pin header.
Channel and Card Address Selection The lower and upper channels on the DBK16 are multiplexed into one of the channels (0 to 15). The base channel (that the DBK16 is multiplexed into) is set by the shunt jumper on the16×2 header designated JP1 (see previous figure, DBK16 Board Layout). Each base channel can have up to 16 expansion channels multiplexed into it. Since the DBK16 represents two expansion channels, eight DBK16 cards can be multiplexed into each base channel.
Calibrating DBK16 for Daq Devices Reference Note: This section covers calibrating a DBK16 that is being used in a Daq device application. LogBook users: refer to Calibrating DBK16 and DBK43A for LogBook, which begins on page 15. Bridge circuit transducers are used for many different applications, and the DBK16 is flexible enough to support most of them.
4. Determine how the total gain will be distributed between input amplifier gain, filter gain and scaling amplifier gain. (See examples on page 12.) 5. Hook up the transducer to the terminal strips labeled Lower or Upper according to the figures in the Card Connection section. Install the appropriate bridge completion resistors if applicable. 6.
Software Setup Reference Notes: o DaqView users - Refer to chapter 3, DBK Setup in DaqView. o LogView users - Refer to chapter 4, DBK Setup in LogView. GageCal Program GageCal is not used for LogBook applications. Note: GageCal is best suited for a load cell application To install the GageCal program on your computer, close all other programs and run SETUP.EXE on Disk 1 (or CD-ROM, as applicable) from Windows 3.1, 3.11, or Windows 95/98/Me. Follow the installation instructions from the setup program.
Example The following examples perform selected steps for a typical setup. There will be strain gage and load cell examples. Referring to the typical setup procedure, step 3 says to determine the maximum voltage from the transducer at maximum load or strain. A strain gage example: Most strain gages come with Gage Factors (GF) used to calculate the approximate output of the bridge circuit with a typical strain value.
Launch DaqView and set it up for the DBK16 at the correct Daq device input channel determined by the setting of JP1 and S1. On return to the DaqView main spreadsheet screen, notice the type column in the spreadsheet. All the DBK16 channels should say bridge. Changing the type will allow us to set the offset and gains in the DBK16. When setting up the DBK16 gains, enable only the channel you are setting up. Turn all the others off in DaqView.

Calibrating DBK16 and DBK43A for LogBooks Reference Note: This section covers calibrating a DBK16 that is being used in a LogBook application. Daq users: Refer to Calibrating DBK16 and DBK43A for Daq Devices, which begins on page 9.
By using software-controlled multiplexers, on-board reference voltages can be read by the data acquisition system so that precise gains and offsets can be set. LogView provides a means of easily controlling the calibration multiplexers so that the reference voltages can be displayed while the trimpots are being adjusted. There are four trimpots to set up each channel circuit.
Shunt – applies a shunt resistor to the bridge to simulate a load. Shunt calibration is identical to 2-Point calibration except that the second point is simulated so that applying a load near the gage’s maximum load is unnecessary. To simulate a bridge imbalance, a shunt resistor is placed across one leg of the bridge. Once the shunt resistor value has been calculated, it is applied to the bridge to provide the desired simulated load. No gain calculations are required to perform this calibration method.
Analog Input Channel Configuration Window, Button and Screen … “User Scaling” Tab Selected For all of the strain gage channels that are to be adjusted, set their ranges to +5V. Click the DBK Parameters tab to expose the strain gage signal conditioning programmable settings. Click the Attach button to substantiate a connection between the PC and the LogBook.
3. In the Param1 column (see next figure for location), select all of the DBK43A channels that are to be adjusted. 4. Set Mode equal to Excitation from the drop down list (located above the DBK Parameters tab). 5. Turn off all the channels in the system except for those DBK43A channels that are to be adjusted. Selecting “Mode = Excitation” for DBK Parameter 1 6. Click the Download button to send the current configuration to the LogBook. 7.
10. Return the physical calibration switches (of the applicable DBK43As) to the NORM position. 11. In LogView, open the LogBook Hardware Configuration Window (hardware tree) and select NORM for each DBK43A. This completes the section entitled: “Procedures Common to All Calibration Steps (Required)” Nameplate Calibration and Manual Calibration To properly calibrate a strain gage channel using the Nameplate method, the required gain must first be calculated.
Consider a 3000 pound load cell rated at 2.05 mV/V using 10 V of excitation (assume a 350Ω load cell). When 3000 pounds is applied, the voltage out of the load cell is 20.5mV. VLC = (10 * 2.05×10-3) = 20.5 mV If 1000 pounds were applied, we would see 6.833 mV. This is arrived at as follows: (1000/3000) * 10 * 2.05×10-3 = 6.
The majority of the gain should be assigned to the Input Amplifier, with the Scaling Amplifier used for fine-tuning. If the filter is enabled, a gain of x2 is automatically introduced. The input amplifier has a gain range of ×100 to ×1250; the filter gain ×1 or ×2; and the scaling amplifier has a range of ×1 to ×10. For the strain gage example, if we round off our gain to ×420, any of these possible settings will work.
Channel Calibration Procedure Adjust the Offset The following steps are used to adjust the offset. 1. In the Param1 column (see page 19 for location), select all of the DBK43A channels that are to be adjusted. 2. Select Mode = SetOffset from the drop down list above the grid. This selection commands the calibration multiplexer to route the 0.0V reference through the entire analog path (see following figure). “Mode = Offset” 0.0 Volt Reference is Routed 3.
“Mode = SetInputGain,” 5 milli-Volt Reference Route 3. Turn off all the channels in the system except for those DBK43A channels that are to be adjusted. 4. Click the Download button to send the current configuration to the LogBook. 5. Select Indictors \ Enable Input Reading Column from the menu bar to display the values for each channel. 6. For the associated channel, set the voltage to [GI * GF * 0.005] for each transducer by adjusting the trimpot labeled GAIN.
3. Turn off all the channels in the system except for those DBK43A channels that are to be adjusted. 4. Click the Download button to send the current configuration to the LogBook. 5. Select Indictors \ Enable Input Reading Column from the menu bar to display the values for each channel. 6. For the associated channel, set the voltage to [GT * 0.005] for each transducer by adjusting the trimpot labeled SCALE. Use the total system gain (GT ) calculated earlier. Example: If GT = 435.
“Mode = Bridge,” Reference Route 3. Turn off all the channels in the system except for those DBK43A channels that are to be adjusted. 4. Click the Download button to send the current configuration to the LogBook. 5. Select Indictors \ Enable Input Reading Column from the menu bar to display the offset values for each channel. 6. For the associated channel, set the offset voltage to 0.0V for each transducer by adjusting the trimpot labeled OFFSET.
Adjust the Offset For the associated channel, apply the first calibrated load to each gage (typically no-load) and set the voltage to 0.0V for each transducer. This is accomplished by adjusting the trimpot labeled OFFSET. If the first point is actually a calibrated load, you will need to move the load to each gage, one at a time, to adjust its associated offset. Adjust the Input and Scale Amplifier Gain Complete the following steps to adjust the channel gain. 1.
Shunt Calibration Shunt calibration is virtually identical to the 2-Point method just discussed, except that the second point is simulated. The simulated load is achieved by shunting one leg of the bridge with a shunt resistor. Shunt calibration is the preferred calibration method when applying a real load (of a value approximating the maximum expected load) is not practical. To adjust the channel gain, the shunt must be applied to the bridge.
VD = (150/150) * 5 * 0.90 = 4.5V For DBK16, only … Externally apply the shunt resistor and set the voltage to VD, as derived above for each transducer. This is done by adjusting the trimpots labeled GAIN and SCALE for the associated channel. The GAIN trimpot is used for course adjustment; and the SCALE trimpot for fine-tuning. For DBK43A only … DBK43 is equipped with a physical switch that allows the shunt to be applied when directed by the software.
11. Select Indictors \ Disable Input Reading Column from the menu bar. 12. Return the physical NORM/CAL switches (of the applicable DBK43As) to the NORM position. 13. In LogView, open the LogBook Hardware Configuration window and return each DBK43A back to NORM. Repeating the Process Since adjusting the gain for the first time will have an affect on the offset, it is recommended that offset and gain adjustment be performed twice for each channel.
Periodic Calibration Without Trimpots Once the trimpots have been adjusted during initial installation, periodic trimming can be performed through LogView’s 2-Point software calibration. The LogView procedure does not require the use of trimmpots and should not be confused with the 2-point method discussed in this section of the manual. Refer to the LogView chapter in the LogBook User’s Manual for information regarding 2-point calibration via software.

Simultaneous Sample and Hold Some applications require every channel in a scan group to be read at the same instant, as opposed to being read with a delay, e.g., 10 µs between channels. Simultaneous Sample and Hold (SSH) is a means of obtaining such instantaneous data on multiple channels while avoiding time-skew problems. A sample case in which SSH is desirable: A performance analysis of an engine is a classic example of a case in which SSH is desirable.
Examples of Bias Resistor Selection Options Gain Settings On the card, each channel has a gain-set switch and holes for gain resistors labeled RG1 to RG4. The figure at the right shows gain values for switch settings 0 to 4, with 0 being equal to x1 and 4 being equal to x500. If a custom gain is desired, the switch is set to position 0 and a gain resistor must be mounted and soldered onto the card.

Power Requirements The DBK24 can be powered by an included AC adapter, a standard 12-V car battery, or an optional rechargeable nickel-cadmium battery module (DBK30A). This power flexibility makes the DBK24 ideal for field and remote data acquisition applications. Power supplied to the DBK24 powers the on-board regulator.

DBK24 simplified Component Layout Strip some insulation from the ends of the wires (no more than 1/4"). Insert wire into the screw terminal receptacle so that only the bare portion of wire extends into the opening. Bare wire should not extend more than 1/16" beyond the receptacle. These steps are essential to maintaining proper voltage isolation. After the wire ends are in place, turn the slot-head screw at the top of the block until the receptacle grips the wire firmly. Do not over tighten.
User Output Configuration The outputs of the DBK24 are designed to switch levels as high as 60 V at 1 A. The next figure shows a typical output hookup with a protective flyback diode in parallel with the load. When driving inductive loads without built-in flyback protection, you must provide this diode. CAUTION Failure to provide adequate flyback protection may result in damage to the DBK24’s output stage. Each unit is configured via the on-board DIP switch (S1) for its unique base address.

14 VDC Mode (default) This mode provides 14 VDC for 3.4 A-hr. The typical battery runtime is from 3 to 6 hours depending on the load. Unless 28 VDC is required, the 14 VDC mode should be used in your LogBook applications. Unless you need 28 V, leave the unit in the 14 VDC mode. Use of the 28 VDC mode results in a lower runtime, as only one battery pack can be used for 14 VDC. When in the 14 VDC mode, both packs are used in parallel, resulting in a longer runtime for the same application.
Hardware Setup Configuration The only configuration option is the choice of modes (14 VDC, or 28 VDC). If you do not need 28 V, leave SW2 in the default position. If you are using a pre-owned DBK30A, or are unsure of the mode selected, use the following steps to check SW2’s position. Note that new units are always shipped with SW2 selected to the 14 VDC mode. Internal switch SW2 is located on the printed circuit board, near the front center of the unit. To change or verify the mode: 1.
28 VDC Mode. The primary purpose of the 28 VDC mode is to provide power for external loop transmitters. The hookup is simple, as shown below. Another use of the 28 VDC mode is to provide excitation for bridge-type sensors, such as load cells (strain gages). The primary purpose of the 28 VDC mode is to power external user-supplied loop transmitters. The hookup is simple, as shown below. A DIN5 connector allows easy connection of lead wires.
Charging the Battery Module To charge the DBK30A batteries: 1. Connect the adapter to DBK30A’s POWER IN connector. 2. Plug the adapter into the AC power receptacle.
