CHAPTER 1 2 Introduction
Chapter 1 Introduction The PCI-1711U/UL is a universal PCI bus multifunction card. It offers the five most desired measurement and control functions: • 12-bit A/D conversion • D/A conversion (PCI-1711U only) • Digital input • Digital output • Timer/counter A programmable-gain instrument amplifier lets you acquire different input signals without external signal conditioning. An onboard 1K word FIFO buffer provides high-speed data transfer and predictable performance under Windows.
1.1 Features • 16 single-ended inputs • 12-bit A/D converter, up to 100 kHz sampling rate • Programmable gain for each input channel • Automatic channel/gain scanning • Onboard 1K word FIFO buffer with software selectable interrupt • 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-1711U/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 2 Installation
Chapter 2 Installation 2.1 Unpacking After receiving your PCI-1711U/UL package, please inspect its contents first. The package should contain the following items: • PCI-1711U or PCI-1711UL card • Companion CD-ROM (Device Drivers included) • User Manual The PCI-1711U 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 PCI-1711U/UL card into your system, since this will guarantee a smooth installation process.

3 CHAPTER 2 Signal Connections
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 PCI1711U cards via the I/O connector. 3.2 Switch and Jumper Settings PCI-1711U 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.
3.3 Signal Connections Pin Assignment Figure 3-2 shows the pin assignments for the 68-pin I/O connector on the PCI-1711U/UL. Figure 3.

Analog Output Connection The PCI-1711U/UL provides two D/A output channels. 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. Loading current for D/A outputs should not exceed 5 mA. Fig. 3-3 shows how to make analog output and external reference input connections on the PCI-1711U/UL. Figure 3.
3.3.3 Digital Signal Connections The PCI-1711U/UL has 16 digital input and 16 digital output channels. The digital I/O levels are TTL compatible. The following figure shows connections to exchange digital signals with other TTL devices: TTL Devices DO DI D.GND D.GND To receive an OPEN/SHORT signal from a switch or relay, add a pull-up resistor to ensure that the input is held at a high level when the contacts are open. +5V 4.7K D.
3.4 Field Wiring Considerations When you use PCI-1711U cards to acquire data from outside, noises in the environment might 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 the PCI-1711U card.

APPENDIX C 2 Calibration
Appendix C Calibration PCI-1711U 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-1711U/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 Function 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. Connect a DC voltage source of +9.995 V to AI0. 2. Connect AGND to AI1, AI2, AI3, AI4 and AI5. 3. Run the ADCAL.EXE program. 4.
