4.1.2.3 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.
4.1.2.4 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.
4.1.2.5 I/O card
The I/O card handles most of the signal inputs and outputs from the instrument. Two ribbon
cables route these signals from the IB to the I/O card and power is supplied through a power
cable from the power supply.
4.1.2.6 Comm/LPT card
This card is mounted to the left and above the interface board and is used to allow
communication between the MPR E-Scan unit and the Monitor. It also enables the MPR E-Scan
to drive the printer.
