DESCRIPTION

The MSI-P460 Analog Output Card is an 8-bit stack-
through PC/104 card which reqyuires +5V and ±12V from
the PC/104 bus. It provides thirty-two analog output
channels with an output resolution of 8 bits. The card uses
four Analog Devices AD7228A analog-to-digital converters
with unity gain buffer amplifiers for the outputs. The
output ranges are selectable as either 0-5V or 0-10V with
a single hardware jumper. The card uses 16-bit I/O
mapped addressing which is jumper selectable. Outputs
are provided via a 40-pin AMP type 103311-8 connector.
The card outline is shown in Figure 1.
