1. Introduction
1.1 General Description
The A-812PG is a high performance, multifunction analog, digital I/O board for the PC
AT compatible computer. The A-812PG provides low gain (1, 2, 4, 8, 16). The A-812PG
contains a 12-bit ADC with up to 16 single-ended analog inputs. The maximum sample rate
of A/D converter is about 62.5K sample/sec. There are two 12-bits DAC with voltage outputs,
16 channels of TTL-compatible digital input, 16 channels of TTL-compatible digital output
and one 16-bit counter/timer channel for timing input and output.
