3. Signal Connections 3.1 Overview Maintaining signal connections is one of the most important factors in ensuring that your application 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 the PCI-1723 via the I/O connector. 3.
Setting the time to reset the analog outputs Some users will want the capability of clearing each analog output when the system (or PC) issues a reset signal on the PCI bus. Some users will want to clear their analog output only as part of system power-on. The PCI-1723 satisfies both these needs by providing jumper JP1. Depending on the application, this capability may allow analog outputs to be "ZERO" without requiring a complete shutdown of processes controlled by the card.
3.3 Signal Connections Pin Assignment Figure 3-2 shows the pin assignments for the 68-pin I/O connector on the PCI-1723.

Appendix D. Calibration This chapter provides brief information on PCI-1723 calibration. Regular calibration checks are important to maintain accuracy in data acquisition and control applications. We provide the calibration programs or utility on the companion CD-ROM to assist you in D/A calibration. Note: ✎ If you installed the program to another directory, you can find these programs in the corresponding subfolders in your destination directory.
D.1 VR Assignment There is two variable resistors (VR1 and VR2) on the PCI-1723 to adjust the accurate reference voltage. We have provided two test points (See J4 and J7 in Figure D-1) for you to check the reference voltage on board. Before you start to calibrate the D/A channels, please adjust VR1 until the reference voltage on J4 has between +9.9995 ~ +10.0005 V. And adjust VR2 until the reference voltage on J7 has between -9.9995 ~ -10.0005 V. Figure D-1 shows the locations of VR1, VR2, J4 and J7.
D.2 D/A Calibration Note: ✎ Using a precision voltmeter to calibrate the D/A outputs is recommended. The auto-calibration program AutoCali.EXE helps you finish the D/A calibration procedure automatically. Although the procedure is not necessary, the following calibration steps are provided below for your reference in case you want to implement the calibration yourself: 1. To adjust those eight jumpers JP1~JP8 to 0~20 mA. 2. Setting the output range as ± 10 V for channel 0 (BASE+14H). 3.
D.3 Calibration Utility The calibration utility, AutoCali, provides two functions - auto D/A calibration and manual D/A calibration. The program helps the user to easily finish the calibration procedures automatically, however, the user can calibrate the PCI-1723 manually. The following steps will guide you through the PCI-1723 software calibration. Step 1: Access the calibration utility program Cal1723.exe from the default location: C:\Program Files\Advantech\ADSAPI\Utilities\PCI1723/Windows/ Cal1723.
Step 3: After you start to calibrate the PCI-1723, please don’t forget to adjust the VR1 and VR2. Figure D-3: Warning message before start calibration D/A channel Auto-Calibration Step 4: There are eight D/A channels in PCI-1723, select the output range for each channel and then press the start button to calibrate D/A channels (Fig. D-4).
Step 5: Clicking the Start button, the utility will test some registers to make sure the PCI-1723 has stable enough to process the calibrate procedure (Fig. D-5) Figure D-5: Burning test Step 6: D/A channel 0 calibration is enabled (Fig. D-6) Figure D-6: Calibrating D/A Channel 0 Step 7: D/A channel 1 calibration is enabled (Fig.
Step 8: Auto-calibration is finished (Fig. D-8) Figure D-8: D/A Calibration is finished D/A channel Manual-Calibration Step 1: Click the Manual D/A Calibration tab to show the D/A channel manual calibration panel. Eight D/A channels are individually calibrated . Before calibrating, output desired voltage from the D/A channels and measure it through an external precision multi-meter.
Step 3: According to the difference between the output voltage from D/A channel and the value in the multi-meter, adjust the gain, bipolar offset and unipolar offset registers (Fig. D-10) Figure D-10: Adjusting registers Step 4: Adjust registers until they fall between the output voltage from the D/A channel and the value in the multi-meter.
