5.6.2 Analog/Digital I/O Board
The Analog/Digital IO (ADIO) Board is an off-the-shelf, complete data acquisition system
in a compact PC/104 packaging. The analog section contains 32 input channels,
multiplexed A/D converter with 16 bit resolution and 10uS conversion time. Input ranges
are +/-5v or +/- 10V. It also includes on-board DMA support. The analog output section
includes two 12 bit D/A converters. Both sections features simplified calibration using on
board programmable digital potentiometer. The digital I/O section provides 24 digital I/O
lines, which feature high current TTL drivers. The board requires only +5V from the
system power supply and generates its own +/-15V analog supplies on board. The board
operates over the Extended Temperatures range of -25 to +85C. Figure 3 depicts the
ADIO board and Figure 5-9 depicts the ADIO block diagram.
