Installation and Configuration

This chapter describes how to install and software configure the

DAQCard-1200.

Installation

There are two basic steps to installing the DAQCard-1200.

1. You must have Card & Socket Services 2.0 (or a later version) on your

computer.

2. Insert the DAQCard-1200 and attach the I/O cable.

The DAQCard-1200 has two connectors—a 68-pin PCMCIA bus

connector on one end and a 50-pin I/O connector on the other end. Insert

the PCMCIA bus connector into any available Type II PC Card slot until

the connector is seated firmly. Notice that the card is keyed so that it can be

inserted only one way. If your computer supports hot insertion, you may

insert or remove the DAQCard-1200 at any time, whether your computer is

powered on or off.

You can use either a 50-pin female or a 50-pin male cable to plug into the

DAQCard-1200. For more information on these products, see the Optional

Equipment section in Chapter 1, Introduction. Notice that the cable is

keyed so that you can insert it only one way. Be careful not to put strain

on th e I/O cable when inserting it into and removing it from the

DAQCard-1200. Always grasp the cable by the connector you are plugging

or unplugging. Never pull directly on the I/O cable to unplug it from the

DAQCard-1200.

The DAQCard-1200 is now installed. You are ready to make the appropriate

connections to the I/O connector cable as described in Chapter3, Signal

Connections, and to install and configure your software.
