SYSTEM COMMUNICATIONS MODULE
INSTALLATION
The System Communications module plugs into any available System section slot of the
motherboard (J3-J8). The module connector is offset, enduring that it cannot be inserted
backwards. All power requirements are supplied through the motherboard. A standard flat
ribbon 25 conductor cable may be attached to the top edge connectors P2 through P4 for
serial RS-232-C input/output. P2 is primarily designated for modem operation. The cable
provides for a rear panel 25 pin connection. Care should be taken that pin 1 of the cable
(red stripe) and pin 1 of the edge connector is to the left when viewed from the component
side of the mo du le.

1/0
Communication Ports.
