CHAPTER 2 1 Introduction This chapter gives background information on the PCI-1723.
Chapter 1 Introduction Thank you for buying the Advantech PCI-1723. The PCI-1723 is a nonisolated multiple channels analog output card for PCI bus, and each analog output channel is equipped with a 16-bit, double-buffered DAC. It features an auto-calibration function and Board ID. The PCI-1723 is an ideal solution for industrial applications where multiple analog output channels are required.
Flexible Voltage Output Range The PCI-1723 provides a fixed voltage output range of °”10 V to fulfill your flexible range needed applications. Users can define the specific voltage output range and output data format via the enclosed software utility and driver. Keeping Output Values After System Reset Users can independently set the eight outputs to different ranges: °”10 V, 0 ~ 20 mA or 4 ~ 20 mA, and all ranges are software selectable.

CHAPTER 2 2 Installation This chapter gives users a package item checklist, proper instructions for unpacking and step-by-step procedures for both driver and card installation.
Chapter 2 Installation 2.1 Unpacking After receiving your PCI-1723 package, please inspect its contents first. The package should contain the following items: • PCI-1723 card • Companion CD-ROM (Device Drivers included) • User Manual The PCI-1723 card harbors certain electronic components vulnerable to electrostatic discharge (ESD). ESD can easily damage the integrated circuits and certain components if preventive measures are ignored.
• Whenever you handle the card, grasp it only by its edges. DO NOT TOUCH the exposed metal pins of the connector or the electronic components. 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 PC or transport it elsewhere. 2.2 Driver Installation We recommend you to install the driver before you install the PCI-1723 card into your system, since this will guarantee a smooth installation process.
Note: If the autoplay function is not enabled on your computer, use Windows Explorer or Windows Run command to execute SETUP.EXE on the companion CDROM. Step 3: Select the Device Drivers option. Step 4: Select the specific device then just follow the installation instructions step by step to complete your device driver installation and setup. Figure 2.
2.3 Hardware Installation Make sure you have installed the driver first before you install the card (please refer to 2.2 Driver Installation). After the Device Drivers installation is completed, you can then install the PCI-1723 card into any PCI slot on your computer. However, it is suggested that you refer to the computer user’s manual or related documentation if you have any doubt. Please follow the steps below to install the card onto your system. 1.
After the PCI-1723 card is installed, you can verify whether it is properly installed on your system in the Device Manager: 1. Access the Device Manager through Control Panel/System/Device Manager. 2. The device name of the PCI-1723 should be listed on the Device Manager tab on the System Property Page. Figure 2.3: Device Name on the Device Manager If your card is properly installed, you should see the device name of your card listed on the Device Manager tab.
2.4 Device Setup and Configuration The Advantech Device Manager program is a utility that allows you to set up, configure and test your device, and later stores your settings on the system registry. These settings will be used when you call the APIs of Advantech Device Drivers. 2.4.1 Setting Up the Device 1. To install the I/O device for your card, you must first run the Device Installation program (by accessing Start/Programs/ Advantech Device Driver V2.0). 2.
3. Scroll down the List of Devices box to find the device that you wish to install, then click the Add… button to evoke the Device(s) found dialog box such as one shown in Fig. 2-5. The Device(s) found dialog box lists all the installed devices on your system. Select the device you want to configure from the list box and press the OK button. After you have clicked OK, you will see a Device Setting dialog box such as the one in Fig. 2-6. Figure 2.5: “Device(s) Found” Dialog Box 2.4.
5. After you have finished configuring the device, click OK and the device name will appear in the Installed Devices box as seen below: Figure 2.7: Device Name on List of Devices Box Note: As we have noted, the device name “000:PCI-1723 BoardID=0 I/O=6500H” begins with a device number “000”, which is specifically assigned to each card. The device number is passed to the driver to specify which device you wish to control.

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 PCI1723 via the I/O connector. 3.
3.2.1 JP9 Keep last status after hot reset. Default configuration. 3.2.2 JP1~JP8 4~20 mA 0~20 mA 3.2.3 Setting the Time to Reset 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.
