CHAPTER 1 2 Overview Sections include: • Introduction • Features • Specifications • Block Diagram
Chapter 1 Overview 1.1 Introduction The PCI-1713 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 100k samples/s, 12-bit resolution and isolation protection of 2500 VDC. PCI-bus Plug and Play The PCI-1713 uses a PCI controller to interface the card with the PCI bus. The controller fully implements the PCI bus specification Rev 2.1.
Satisfies the Need for Isolation Protection The PCI-1713 provides optical isolation protection of 2500 VDC between the inputs and the PC bus to protect the PC and peripherals from damage due to high voltages on the input lines. It is ideal for the situations where budget-conscious users require flexibility, stability and a high level of isolation protection for their data acquisition system. 1.

CHAPTER 2 2 Installation Sections include: • Initial Inspection • Unpacking • Installation Instructions
Chapter 2 Installation 2.1 Initial Inspection Before installing the PCI-1713, check the card for visible damage. We have carefully inspected the card both mechanically and electrically before shipment. It should be free of marks and in perfect order upon receipt. As you unpack the PCI-1713, check it for signs of shipping damage (damaged box, scratches, dents, etc.). If it is damaged or fails to meet specifications, notify our service department or your local sales representative immediately.
2.3 Installation Instructions The PCI-1713 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 /other cables from the back of the computer. 3.

CHAPTER 3 2 Signal Connections Sections include: • Overview • I/O Connector • Analog Input Connections • Field Wiring Considerations
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-1713 card via the I/O connector. 3.

Differential Channel Connections The differential input configuration has two signal wires for each channel, and the differential input responds only to voltage differences between High and Low inputs. On the PCI-1713 card, when all channels are configured to differential input, up to 16 analog channels are available.

Figure 3.4: Differential Input Ch. - Floating If a floating signal source is connected to the differential input channel, the signal source may exceed the common-mode signal range of the PGIA, and the PGIA will be saturated with erroneous voltage-readings. You must therefore reference the signal source to the AIGND. Figure 3-4 shows a differential channel connection between a floating signal source and an input channel on the PCI-1713 card.
External Trigger Source Connection In addition to pacer triggering, the PCI-1713 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-1713 board. Note!:Don't connect any signal to the EXT_TRG pin when the external trigger function is not being used.

CHAPTER 4 2 Calibration Sections include: • Introduction • VR Assignments • A/D 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 the Advantech Device Manager, on the PCI1713 software CD-ROM. The Advantech Device Manager 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 1. Connect Pin1 to Pin9 and measure the output as "V1" from TP1.
2. Adjust VR4 until | V1 – V2 | < 0.05mV. For example, if the V1 is 0.1mV in the beginning and you get V2 as 0.02mV after adjusting the VR4, you have to adjust the VR4 again. 3. Input -5V to AI0 by signal generator and check if the "Decimal" flickers between 0 and 1. For example, it is 3 for my calibration, so I have to adjust the VR2.
4. Input 5V to AI0 by signal generator and check if the "Decimal" flickers between 4094 and 4095. 5. Input 5V to AI1 by signal generator and check if the "Decimal" flickers between 2047 and 2048. Calibration finished.
