CHAPTER 2 2 Installation This chapter has a package item checklist, proper instructions about unpacking and step-by-step procedures for card installation..
Chapter 2 Installation 2.1 Unpacking After receiving your MIC-3723/3723R package, please inspect its contents first. The package should contain the following items: • MIC-3723/3723R card • Companion CD (Device Drivers included) • User Manual • Rear I/O Module (for MIC-3723R only) MIC-3723/3723R card harbors certain electronic components vulnerable to electrostatic discharge (ESD).
• Whenever you handle the card, grasp it only by its edges. DO NOT TOUCH the exposed metal pins of the connector or the electronic components. Note: Keep the anti-static bag for future use. You might need the original bag to store the card if you have to remove the card from PC or transport it elsewhere. 2.2 Driver Installation We recommend you install the driver before you install the MIC-3723/ 3723R card into your system, since this will guarantee a smooth installation process.
Step 3: Please click ‘CONTINUE’ to proceed to the next step. Step 4: Pleases select ‘Installation’ to proceed to the next step. A list of items will be shown on the screen: ‘Device Manager’, ’Individual Driver’, ‘Example & Utility’, and ‘Advance Options’.
Step 5: Please install the ‘Device Manager’ first. For details on how to install the ‘Device Manager’ step by step, please see the software manual. Step 6: When you’re finished installing the ‘Device manager’, you can install the driver of the corresponding card. Please click the 'Individual Drivers'.
Step 7: Select ‘CompactPCI Series’. Step 8: Select ‘ MIC-3723’ to install its driver. For more information about the software installation, please read the software manual.
2.3 Hardware Installation Make sure you have installed the driver before you install the card (please refer to 2.2 Driver Installation) Once the Device Driver installation is complete, you can install the MIC3723/3723R card in any CompactPCI slot in your enclosure. You should refer to the computer user manual or related documentation if you have any doubts. Please follow the steps below to install the card on your system. Step 1: Remove a cover of an unused slot on your CompactPCI system.
Note: In case you installed the card without installing the Device Driver first, Windows 98/ME will recognize your card as an “unknown device” after rebooting, and will prompt you to provide the necessary driver. You should ignore the prompting messages (just click the Cancel button) and set up the driver according to the steps described in 2.2 Driver Installation. After the MIC-3723/3723R card is installed, you can verify whether it is properly installed on your system in Device Manager: 1.
If your card is properly installed, you should see the device name of your card listed on the Device Manager tab. If you see your device name listed on it but marked with an exclamation sign “!”, it means your card has not been correctly installed. In this case, remove the card device from the Device Manager by selecting its device name and press the Remove button. Then go through the driver installation process again. Then you must restart your computer.
Figure 2.2: Device Manager Dialog Box 2.4.2 Configuring the Device Step 3: Click "Setup" to show the Device Setting dialog box (Fig. 2.3), then you can specify the voltage output range for 8 D/A channels.
Figure 2.3: Device Setting Dialog Box Note: You can select the output voltage range. When selecting voltage source as Internal, users have three options for the output voltage ranges and current ranges: -10 ~ 10 V, 0~20 mA and 4~20 mA. Note: As we have noted, the device name “000:MIC3723 BoardID=0 I/O=bcc0H” begins with a device number “000”, which is specifically assigned to each card. The device number is passed to the driver to specify which device you wish to control.

CHAPTER 3 2 Signal Connections This chapter provides advice on settings and connections for the MIC-3723/3723R.
Chapter 3 Signal Connections 3.1 Overview Maintaining signal connections is one of the most important factors in ensuring that your system is sending and receiving data correctly. A good signal connection can avoid unnecessary and costly damage to your PC and other hardware devices. This chapter provides useful information about how to connect input and output signals to MIC-3723/3723R via the I/O connector. 3.2 Switch & Jumper Settings . Figure 3.
Figure 3.2: MIC-3723R Connectors, Jumpers&Switch Figure 3.
3.2.1 Jumper Settings Table 3.1: Jumper Settings Label Setting JP9 Function description Keep last status after hot reset Reset status after hot reset (default) JP1~JP8 0~20mA (default) 4~20mA 3.2.2 Setting the Analog Output Mode After Reset Some may want the capability of clearing each analog output when the system (or PC) issues a reset signal on the CompactPCI bus. MIC-3723/ 3723R satisfies both these needs with jumper JP9.

3.3 Signal Connections 3.3.1 Pin Assignments Figure 3.4 shows the pin assignments for the 68-pin I/O connector on MIC-3723/3723R. Figure 3.
3.3.2 I/O Connector Signal Descriptions Table 3.2: I/O Connector Signal Description Signal Name Reference Direction Description Vout<0~7> AGND Output Voltage Output, Channels 0 ~ 7. Iout<0~7> AGND Output (Sink) Current Output, Channels 0 ~ 7. AGND -- -- Analog Ground. The two ground references (AGND and DGND) are connected together on the MIC1723 card. DI0<0~15> DGND -- Digital Input/Output Signals. These pins are digital input / Output channel 0 to 15. DGND -- -- Digital Ground.
3.3.3 Analog Output Connection MIC-3723/3723R provides eight D/A output channels, Vout0 ~ Vout7 and the optional Iout0 ~ Iout7. D/A Voltage Output Connections MIC-3723/3723R provides eight D/A output channels, Vout0 ~ Vout7. The voltage output is referenced to a common ground (AGND). There are three types of voltage output connections: 1. Floating load. 2. Grounded load. 3. Differential load with ground. They are shown in the following illustrations. Figure 3.5: Floating-load Connections Figure 3.
Figure 3.7: Differential-load w/Ground Connections Current Sink Connections MIC-3723/3723R’s current loop output uses a 0 to +5 V (unipolar) voltage output as each channel’s driving source. Current drive circuits consist of a power field-effect transistor (FET). The current output’s voltage bias must be less then 50 V for accurate results. The card also provides an internal +12 V power source for current loop excitation. You can use three types of current sink connections: 1.
Figure 3.9: Floating-load w/Grounded Power Figure 3.10: Floating-load w/Internal +12 VDC Current Sink Load and Power Supply You have to select the current sink load and power supply carefully. The current sink circuitry of the MIC-3723/3723R is as shown below. Figure 3.
Where VS: Power supply voltage of current sink. RL: Load of current sink. PD: Power dissipation of FET. When you determine VS and RL, three conditions must be satisfied. VS > (RL + 251) ( 0.02) PD = (VS - (RL + 251) * 0.02) * 0.02 < 0.2 Example 1 If you use the internal power supply VS = +12 V, RL must be less than 349 W. (12 / 0.02 - 251 > RL). Select RL = 200, PD = 0.0696 < 0.2 OK! Example 2 If you use the external power supply VS = +40 V, RL must be less than 1.75 kW (40 / 0.02 - 251 > RL).
3.4 Field Wiring Considerations When you use the MIC-3723/3723R to acquire data from external sources, noises in the environment could significantly affect the accuracy of your measurements if due cautions are not taken. The following measures will be helpful to reduce possible interference running signal wires between signal sources and MIC-3723/3723R.
