description

The 12 bit A/D-D/A card is a high precision data conversion system for PC/486, Pentium, or compatibles. It contains one 12 bits digital to analog channel (setting jumper 2 for selecting unipolar or bipolar) and sixteen 12 bits analog to digital channels (setting jumper 3 for selecting unipolar or bipolar).
