9. Position the power cord so that people cannot step on it. Do not place anything over the power cord. 10. All cautions and warnings on the equipment should be noted. 11. If the equipment is not used for a long time, disconnect it from the power source to avoid damage by transient overvoltage. 12. Never pour any liquid into an opening. This may cause fire or electrical shock. 13. Never open the equipment. For safety reasons, the equipment should be opened only by qualified service personnel. 14.
Safety Precaution - Static Electricity Follow these simple precautions to protect yourself from harm and the products from damage. 1. To avoid electrical shock, always disconnect the power from your PC chassis before you work on it. Don't touch any components on the CPU card or other cards while the PC is on. 2. Disconnect power before making any configuration changes. The sudden rush of power as you connect a jumper or install a card may damage sensitive electronic components.

CHAPTER 1 2 Overview
Chapter 1 Overview 1.1 Introduction The PCI-1715U is a 12-bit 32-channel analog input card for the PCI bus. It provides 32 analog input channels with a sampling rate up to 500k samples/s, 12-bit resolution and isolation protection of 2500 VDC. 1.
CHAPTER 2 2 Installation
Chapter 2 Installation 2.1 Unpacking After receiving your PCI-1715U package, please inspect its contents first. The package should contain the following items: • PCI-1715U Card • Companion CD-ROM (DLL driver included) • User Manual The PCI-1715U card harbors certain electronic components vulnerable to electrostatic discharge (ESD). ESD could easily damage the integrated circuits and certain components if preventive measures are not carefully paid attention to.
2.2 Driver Installation We recommend you install the software driver before installing the PCI1715U module, since this will guarantee a smooth installation process. The 32-bit DLL driver Setup program for the PCI-1715U module is included on the companion CD-ROM that is shipped with your module package.
2.3 Installation Instructions The PCI-1715U can be installed in any PCI slot in the computer. However, refer to the computer user's manual to avoid any mistakes and danger before you follow the installation procedure below: 1. Turn off your computer and any accessories connected to the computer. Warning!TURN OFF your computer power supply whenever you install or remove any card, or connect and disconnect cables. 2. Disconnect the power cord and any other cables from the back of the computer. 3.
3 CHAPTER 2 Signal Connections
Chapter 3 Signal Connections 3.1 Overview Correct signal connections are one of the most important factors in ensuring that your application system is sending and receiving data correctly. A good signal connection can avoid much unnecessary and costly damage to your valuable PC and other hardware devices. This chapter will provide some useful information about how to connect analog input signals to the PCI-1715U card via the I/O connector. 3.
Table 3.1: I/O Connector Signal Description Signal Name Reference Direction Description AI<0…31> GND Input Analog Input Channels 0 through 31. GND - - Ground EXT_TRG GND Input A/D External Trigger. 3.3 Analog Input Connections This section continues to describe how to make analog input signal connections to the PCI-1715U card via the I/O connector.
Differential Channel Connections The differential input configuration has two signal wires for each channel, and each input responds only to voltage differences between High and Low inputs. On the PCI-1715U card, when all channels are configured to differential input, up to 16 analog channels are available. If one side of the signal source is connected to a local ground, the signal source is ground-referenced.
External Trigger Source Connection In addition to pacer triggering, the PCI-1715U card also allows external triggering for A/D conversions. A low-to-high edge coming from EXT_TRG will trigger an A/D conversion on the PCI-1715U board. Note: Please ascertain that turn on your external trigger source and connect it to "EXT_TRG" BEFORE acquire analog input signals. Note: Don't connect any signal to the EXT_TRG pin when the external trigger function is not being used.
3.4 Field Wiring Considerations When you use the PCI-1715U card to acquire outside data, environmental noise can seriously affect the accuracy of your measurements if you don’t provide any protection. The following suggestions will be helpful when running signal wires between signal sources and the PCI-1715U card. • Please make sure that you have carefully routed signal cables to the card. You must separate the cabling from noise sources.
CHAPTER 4 2 Calibration
Chapter 4 Calibration 4.1 Introduction Regular calibration checks are important to maintain accuracy in data acquisition and control applications. To assist users in the A/D calibration process, we provide one calibration program, ADCAL.EXE, on the PCI-1715U software CD-ROM. The ADCAL.EXE program makes A/D calibrations easy. It leads you through the calibration and setup procedure with a variety of prompts and graphic displays, showing you all of the correct settings and adjustments.
The following list shows the function of each VR: VR Function VR1 A/D full scale (gain) VR2 A/D bipolar offset VR3 A/D unipolar offset VR4 PGIA initial offset TP1 PGIA output 4.3 A/D Calibration Regular and accurate calibration procedures ensure the maximum possible accuracy. The ADCAL.EXE calibration program leads you through the whole A/D offset and gain adjustment procedure. The basic steps are outlined below: 1.
