Faceplate
The faceplate measures 35.5 millimeters (1.4 inches) wide by
177.8 millimeters (7 inches) high. Two concentric screws lock
the module assembly into the module mounting unit. A win-
dow on the faceplate shows the CPU LEDs during operation.
Besides locking the module in place, the faceplate also protects
the circuit components and creates a chimney for proper air
flow within the cabinet.
The IMCPM02 module has two connectors on the faceplate. A
CTT terminal plugs into the round connector and an RS-232-C
cable from the EWS station plugs into the DB-25 connector.
Circuit Board
The circuit board features state-of-the-art circuitry. On the
IMCPM02 circuit board are static random access memory
(SRAM) and read only memory (ROM), a processor running at
16 megahertz, direct memory access (DMA) circuits, Bailey
