The MSI-P450 series is a
low cost, high performance analog I/O board providing four 12-bit
analog input channels and up to four 16-bit analog output channels. The
board is designed for use with all PC/104 embedded systems. Eight
models provide from 1 to 4 analog outputs with or without 4 analog
inputs. Analog input channels are each selectable for 0-5V or 0-10V
with a maximum non-linearity of ±1 LSB. Each analog output
channel is selectable for 0-10V, ±5V or ±10V
with a maximum non-linearity of ±6 LSB. The card operates
from a single +5V supply.
The card employs an ADS7842 for A/D inputs and up to four DAC7741 for
D/A outputs. Potentiometers are provided for adjustment of the offset
and gain of each analog output. Single 10-pin connectors provide
for the analog inputs and the analog outputs.
card is I/O mapped using 16-bit addressing to select the input channels
and device status. Option jumpers are provided for specifying the card
base addresses A4 thru A9, A14 and A15. I/O reads and
writes are 16 bits in length for efficient software sequences for
The card is supplied with a User Manual containing detailed hardware
descriptions with schematic diagrams and a sample 'C' program example.
