Introduction
The advancre A/D-D/A digital I/O card (called advence card) is a high precision data conversion/acquisition system for PC/XT, PC/AT, PC/386, or compatibles. It contains two digital to analog channels with unipolar or bipolar format,eight differential analog to digital channels or sixteen single end analog to digital channels conversion with unipolar or bipolar format, and two digital I/O channels with 8 bits line for each channel.

The features of the advance card are:

-Resolution:
12 bits.
-Output Channel:
two. (one standard, one optional)
-Output Voltage Setting:
unipolar or bipolar selectable.
1. unipolar output:   0V to 10V.
2. bipolar  output: -10V to 10V
-Conversion time:
lusec.
-Accuracy:
1. linearity error:

Fullscalar Adjustments
Before getting start, you must ensure the full scalar voltage are adjusted to satisfy the computer power.
D/A Voltage Adjustment
1.
 Short JP4-2 and JP4-3
2.
 Run ADJU.EXE to selsct D/A voltage adjustment.
3.
 Measure output voltage:

Pin 15 and Pin 24 for D/A channel 1.
Pin   2 and Pin 24 for D/A channel 2.
4. Adjust VR1 (for D/A channel 1) until output voltage is equal to 10V.

Adjust VR2 (for D/A channel 2) until output voltage is equal to 10V.

A/D Voltage Adjustment
1.
 Short JP4-2 and JP4-3.
2.
 Short JP6-1 and JP6-2.
3.
 Short JP7-2 and JP7-3 for unipolar.
4.
 Input voltage to A/D channel by power source.
5. Run ADJU.EXE to select A/D voltage adjustment.
6.
 Adjust VR5 until digital output is 4095.
We note that, if you use bipolar, please adjust VR3 and VR4 by yourself.
