Page 6 - HARDWARE INSTALLATION; Initial Board Setup
3 HARDWARE INSTALLATION 3.1 Initial Board Setup The CIO-DAC## has one bank of gain switches for each analog output channel, onebase address switch, a simultaneous update jumper for each DAC pair, a “power-upstate” selection jumper and one wait state jumper block which must be set beforeinstalling th...

. Figure 3-3. Simultaneous Update Jumper 3.5 Analog Output Range Switches The analog output voltage range of each channel can be set with a set of five gangedDIP switches. The switch blocks are located on the board below the calibrationpotentiometers. The switch blocks are labeled 0 to 15 (0 to 7 on...
Page 10 - Testing the Installation
To set a channel to a particular range, read the switch positions as UP or DN (down)from left to right in the row beside the range you desire. For example, the ±5V range is: UP>DN>DN>UP>DN. 3.6 Installing the CIO-DAC## in the Computer Turn the power off. Remove the cover of your computer...
Page 11 - Signal Connection
3.9 Signal Connection The analog outputs of the CIO-DAC## are two-wire hookups. A signal, labeledD/A # OUT on the connector diagram below, and a Low Level Ground (LLGND).The low level ground is an analog ground and is the ground reference which shouldbe used for all analog hookups. Possible analog o...

3.10 Connector Diagram The CIO-DAC## connector is a 37-pin D-type connector accessible from the rear ofthe PC through the expansion backplate. The connector accepts female 37-pin D type connectors, such as those on theC37FF-2, 2 foot cable with connectors. If frequent changes to signal connections o...
Page 13 - REGISTER ARCHITECTURE; HEX VALUE
4 REGISTER ARCHITECTURE The CIO-DAC## is a simple board to understand. All control and data isread/written with simple I/O read and write commands. No interrupt or DMAcontrol software is required. Thus, the board's functions are easy to control directlyfrom BASIC, C or PASCAL. 4.1 Control & Data...
Page 15 - Output Transfer Functions
4.2 Output Transfer Functions To program a DAC, you must select the output you desire in volts, then apply atransfer function to that value. The transfer function for code = output is: The UNIPOLAR transfer function of the DAC is: FSV / 4096 * CODE = OutV or CODE = OutV / FSV * 4096 For Example:If t...
