7.1.1 Console Cards
IB (interface board) for external connection
The interface board is located on the back wall of the console. Most external connections are
made to connectors that plug into this board. The only exceptions are optional features that
require connections to optional available connectors located on the side of the console.
Power supply
The power supply is located in the top of the console and serves as a hold down clamp for the
analog output modules. The power supply supplies power to both the I/O card and also the IB.
The voltages supplied are +5 vdc and +/- 15 vdc.
I/O card
The I/O card handles most of the signal inputs and outputs from the instrument. Three ribbon
cables from this card route the signals from the IB to the I/O card and power is supplied through
a power cable to the I/O card from the power supply.
CPU card
The CPU card is found plugged into the PC/104 bus connectors of the I/O card. The CPU card
operates with a X86 based STPC Atlas microprocessor running at 133 MHZ. The CPU card has
a built-in flash EPROM hard disk drive, which contains the operating software, parameters and
calibration points for the system.
Comm/LPT card
This card is mounted to the left above the interface board and is used to allow communication
between the Monitor and the MPR E-Scan units. It also enables the Monitor to drive the printer
and provides connections for the Remote Status Panel (RSP).
