CHAPTER 1 2 Introduction This chapter introduces the PCI-1710U cards and their typical applications.
Chapter 1 Introduction The PCI-1710U/HGU is a PCI-Bus multifunction card for IBM PC/XT/ AT or compatible computers. It offers the five most desired measurement and control functions: • 12-bit A/D conversion • D/A conversion • Digital input • Digital output • Timer/counter. A programmable-gain instrument amplifier lets you acquire different input signals without external signal conditioning. An onboard 4K word FIFO buffer provides high-speed data transfer and predictable performance under Windows.
1.1 Features • 16 single-ended or 8 differential A/D inputs, switch selectable • 12-bit A/D converter, up to 100 kHz sampling rate • Programmable gain for each input channel • Automatic channel/gain scanning • Onboard 4K word FIFO buffer with software selectable interrupt • Software selectable Bipolar/Unipolar analog input ranges • 16 digital inputs and 16 digital outputs, TTL compatible • Two 12-bit analog output channels • Onboard programmable counter • Universal PCI-Bus (Support 3.
Onboard Programmable Timer/Counter PCI-1710U/HGU/UL provides a programmable timer counter for generating pacer trigger for the A/D conversion. The timer/counter chip is 82C54, which includes three 16-bit counters of 10 MHz clock. One counter is used as an event counter for counting events coming from the input channel. The other two are cascaded together to make a 32-bit timer for pacer trigger time base.

Chapter 2 Installation 2.1 Unpacking After receiving your PCI-1710U/HGU/UL package, please inspect its contents first. The package should contain the following items: • PCI-1710U, PCI-1710HGU or PCI-1710UL card • Companion CD-ROM (Device Drivers included) • User Manual The PCI-1710U cards harbor certain electronic components vulnerable to electrostatic discharge (ESD). ESD can easily damage the integrated circuits and certain components if preventive measures are ignored.
. 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 a PC or transport it elsewhere. 2.2 Driver Installation We recommend you install the driver before you install the PCI-1710U/ HGU/UL card into your system, since this will guarantee a smooth installation process. The Advantech Device Drivers Setup program for the PCI-1710U//HGU/UL card is included in the companion CD-ROM that is shipped with your DA&C card package.

CHAPTER 3 2 Signal Connections This chapter provides useful information about how to connect input and output signals to the PCI-1710U cards via the I/O connector..
Chapter 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 PCI1710U cards via the I/O connector. 3.2 Switch and Jumper Settings PCI-1710U cards have one switch for BoardID setting.
If you need to adjust it to other numbers, set SW1 by referring to DIP switch settings below. Table 3.

Differential Channel Connections Differential input connections use two signal wires per channel. The card measures only the voltage difference between these two wires, the HI wire and the LOW wire. If the signal source has no connection to ground, it is called a "floating" source. A connection must exist between LOW and ground to define a common reference point for floating signal sources. To measure a floating sources connect the input channels as shown below: HIGH + + Vs - LOW + Vin - A.

You can use the internal precision -5 V or -10 V reference to generate 0 to +5 V or 0 to +10 V D/A output. Use an external reference for other D/A output ranges. The maximum reference input voltage is ±10 V and maximum output scaling is ±10 V.

APPENDIX C 2 Calibration This appendix provides brief information on PCI-1710U card calibration. Regular calibration checks are important to maintain accuracy in data acquisition and control applications.
Appendix C Calibration PCI-1710U cards are calibrated at the factory for initial use. However, a recalibration of the analog input and the analog output function is recommended: 1. Every six months. 2. Everytime the analog output range is changed. We provide the Advantech Device Manager on the companion CD-ROM to assist you with D/A and A/D calibration. The Advantech Device Manager makes calibration easy.
C.1 VR Assignment The five variable resistors (VRs) on the PCI-1710U/HGU/UL board help you make accurate adjustment on all A/D and D/A channels. See the figure in Appendix C for help finding the VRs. The following list shows the function of each VR: VR VR1 VR2 VR3 VR4 (PCI-1710U/HGU) VR5 (PCI-1710U/HGU) Function A/D unipolar offset A/D bipolar offset A/D full scale D/A0 full scale D/A1 full scale Figure C.
C.2 A/D Calibration Note: Using a precision voltmeter to calibrate the A/D outputs is recommended. Regular and accurate calibration ensures maximum possible accuracy. The A/D calibration tool in the Advantech Device Manager leads you through the whole A/D offset and gain adjustment procedure. The basic steps are outlined below: 1. In the Advantech Device Manager, set analog input channel AI0 as single-ended, bipolar, range ±5 V, and set AI1 as single-ended, unipolar, range 0 to 10 V. 2.
3. Connect a DC voltage source with a value of 4094.5 LSB (4.9953 V) to AI0. Adjust VR3 until the output from the card's AI0 flickers between 4094 and 4095. 4. Connect a DC voltage source with value equal to 0.5 LSB (1.22mV) to AI1. Adjust VR1 until the output codes from the card's AI1 flickers between 0 and 1.
5. The A/D calibration is finished after the foregoing steps. A/D code Mapping Voltage Hex. Dec. Bipolar ±5V Unipolar 0 to 10V 000h 0 -4.9971 V 0V 7FFh 2047 -0.0024 V 4.9947 V 800h 2048 0V 4.9971 V FFFh 4095 4.9947 V 9.
C.3 D/A Calibration (PCI-1710U/HGU) Note: Using a precision voltmeter to calibrate the D/A outputs is recommended. In a way similar to the A/D Calibration, the D/A calibration tool in the Advantech Device Manager leads you through the whole D/A calibration procedure. 1. Measure the DA0 output with a 4 1/2-digit digital meter. Adjust the VR4 until the output value equals 4.9988V.
2. Measure the DA1 output with a 4 1/2-digit digital meter. Adjust the VR5 until the output value equals 4.9988V. 3. The D/A calibration is finished after the foregoing steps.
