68-Pin SCSI Type III Pinout Standard 68-Pin SCSCI Type III, Socket (Female) Connector with Orb Pin 1 2 3 Signal Description / Comments Pin Signal Description / Comments DACLKIN/ CNTR1 See Pin 39 [Note 4] ADCLKIN See Pin 5 [Note 3] External DAC Clock In or Counter 1. Rising or Falling Edge Sensitive.
SCSI III Pinout Notes (Apply to the preceding table.) Note 1: AOUT 1 (DAC1) applies to DaqBoard/500 only. The clock source of the secondary DAC1 channel may be software command, DAC1 Pacer clock, or Channel 0 clock source. Likewise, the return line (ARET 1) only applies to the DaqBoard/500. Note 2: AOUT 0 (DAC0) applies to DaqBoard/500 only. The clock source of the primary DAC0 channel may be software command, DAC0 Pacer clock, or an external event (DACLKIN).
Clocks, Triggers, Counters, and Timers ADCLKIN – Uses pin #2 or pin #5. ADCLKIN is the ADC External Pacer Clock Input. This input recognizes TTL level signals and is edge sensitive. The active edge is selectable as either rising or falling. The ADCLKIN signal connection can be made at either pin #2 or pin #5, but NOT both at the same time. ADCLKOUT/TMR1 – Uses pin #37 for one of the following two functions. ADCLKOUT is the ADC’s External Clock Output.
DACLKIN/CNTR1 – Uses pin # 1 or pin # 39 for one of the following two functions. DACLKIN is the External DAC Pacer clock input. This input recognizes TTL level signals and is edge sensitive. The active edge is selectable as either rising or falling. CNTR1 is the general purpose Counter 1 clock input. This input recognizes TTL level signals and is rising edge sensitive. The input clock rate cannot exceed 500 kHz. The clock source must provide a minimum pulse width of 100 ns.
TB-100 Terminal Connector Option The TB-100 Terminal Connector option can be used to connect all signal I/O lines that are associated with a DaqBoard/500 or /505. TB-100 can connect to either board’s 68pin SCSI III connector via a 3 ft., 68-conductor cable (CA-55 or the shielded CA-56); or via a 6 ft. shield cable (CA-56-6). TB-100 Pinout The “Pin” column refers to the pin no. on the 68-Pin SCSI III Connector.
TB-100 Notes (Apply to the preceding table.) Note 1: Digital Common Pins on the SCSI III connector are: 35, 36, and 40. Note 2: Analog Common Pins on the SCSI III connector are: 24, 27, 29, 32, 59, 64, and 67. Note 3: References are not provided for DaqBoard/500 Series devices. For this reason POSREF and NEGREF are tied to the Analog Return signals. POSREF connects to ARET1 (Pin 20 on the DaqBoard) and NEGREF connects to ARET0 (Pin 54 on the DaqBoard).
Signal Types Floating Sources A Floating Source is a signal that has no connection to the building's power ground. Examples of Floating Sources are thermocouples, batteries and battery powered devices, and signals from optically isolated devices. When connecting Floating Sources to a data acquisition board, the ground reference of the signal must be tied to the analog ground (AGND) in order to establish a common reference point.
Differential (DIFF) In installations where each Ground Referenced Source signal has a local ground [signals located remote from one another] the Differential configuration must be used. Since the Differential configuration only responds to the difference in a signal between its high and low voltages, any Common Mode Voltage will be cancelled out. In addition, Differential configuration provides the best performance of the two configurations in an electrically noisy environment.
Differential for Floating Signal Sources Floating Signal Sources are typically wired to a data acquisition board in Single-Ended configuration. However, when the Floating Source signal leads pass through an electrically noisy environment, Differential configuration will give the best performance. When wiring Floating Signal sources in Differential configuration, a resistor can be connected from the low side of the sources to analog ground (AGND).
Configuration 3 Configuration through Software DaqBoard/500 Series boards have no hardware jumpers or switches. All data-acquisition settings such as analog input, data collection rates, input voltage range, and operating modes are configured through application software. A DaqView software driver provides an application level software interface to Windows NT, 2000, and XP. Software packages such as LabVIEW can also be used.
DAC Ranges The output range of the DaqBoard/500 DACs [DAC0 and DAC1] can be independently set to either ±10 V, or 0 to 10 V. The following table indicates the maximum resolution for each range. Note that resolution is not accuracy. Resolution defines the minimum definable voltage increment. Absolute DC accuracy and relative accuracy define exactly how close the actual voltage output will be to the expected output.
Software and Board Operation 4 Overview …… 4-1 Out-of-the-BoxTM Software …… 4-1 Drivers for Third-party, Icon-driven Software …… 4-2 DaqCOM Driver …… 4-2 Theory of Operation …… 4-3 Overview DaqBoard/500 Series boards have several software options. Three types of software are available: Out-of the-box graphical programs, e.g., DaqView, ViewXL, and post acquisition data analysis programs such as eZ-PostView, eZ-TimeView, and eZ-FrequencyView. drivers for third-party, icon-driven software such as LabVIEW.
Reference Notes: The software documents: DaqView, ViewXL, and Post Acquisition Data Analysis User’s Guide, are available in PDF version. During software installation, Adobe® PDF versions of user manuals will automatically install onto your hard drive as a part of product support. The default location is in the Programs group, which can be accessed from the Windows Desktop. Refer to the PDF documentation for details regarding both hardware and software.
Theory of Operation Process Definitions In order to best understand how to operate the various board functions, it is important to first understand the language that will be used to describe the board processes. The following is a list of pertinent terms and definitions used in this document. ADC Analog to Digital Converter, also referred to as A/D. This is the circuitry that samples the voltage present at one of the inputs and translates that reading to a number that is representative of the input voltage.
ADC and DAC Trigger This is the signal or impetus that initiates or terminates an Acquisition. Essentially the Trigger Starts or Stops the ADC or DAC PACER Clock. ADC Channel Configuration RAM This is the term used for the ADC’s Channel, Gain, Range, and Input Configuration lookup table. The length of this table can be anywhere from 1 element to 176 elements. When an ACQUISITION is in process, the board will sequentially go through this list to determine the channel and gain setting for the next conversion.
Starting (Triggering) an ADC Acquisition There are several methods that can be used to initiate an acquisition, all of these are achieved by triggering or gating the ADC clock as mentioned previously. Note that a trigger is an edge active event and a gate is a level controlled enable. An acquisition can be initiated via the following: o o o Software External Gate (ADTRGIN) External Trigger (ADTRGIN) ADC Software Software can be used to start and stop the on-board ADC pacer clock.
Stopping an ADC Acquisition (CLOCK) Typical ways of halting an acquisition involve use of one of the following: o o o Software External Gate (ADTRGIN) External Trigger (ADTRGIN) ADC Software The acquisition can be stopped by software control. ADC External Gate An ADC clock may also be “switched off” with the external trig/gate input (ADTRGIN). Refer to the section entitled ADC External Gate (on page 4-5 ) for additional information about this mode.
Clocking the DAC DaqBoard/500 Only DaqBoard/500 Only The DaqBoard/500 includes two DAC channels. The clock source of the primary DAC0 channel may be any of the following: o DAC0 Pacer Clock o External Event (DACLKIN). The clock source for the secondary DAC1 channel is limited to the following sources: o DAC1 Pacer Clock o Channel 0 Clock Source. DAC Software Update A single D/A conversion may be initiated by an asynchronous software update.

Analog-to-Digital Converter (ADC) A circuit or device that converts analog values into digital values, such as binary bits, for use in digital computer processing. API Application Program Interface.
Differential mode voltage Differential mode voltage refers to a voltage difference between two signals that are referenced to a common point. Example: Signal 1 is +5 VDC referenced to common. Signal 2 is +6 VDC referenced to common. If the +5 VDC signal is used as the reference, the differential mode voltage is +1 VDC (+ 6 VDC - +5 VDC = +1 VDC). If the +6 VDC signal is used as the reference, the differential mode voltage is -1 VDC (+ 5 VDC - +6 VDC = -1 VDC).
