4.4 Connecting Communications Cards to Wiring
Signal wiring connections to the communications cards are made through the communications port
connector and through TELCO (RJ11) connectors supplied with certain modem cards. These
connections are summarized in Table 4-4 and detailed in Sections 4.4.1 to 4.4.5.

NOTE: Use a standard screwdriver with a slotted (flat bladed) 1/8" width tip when wiring all
terminal blocks.
Failure to exercise proper electrostatic discharge precautions (such as wearing a grounded wrist
strap) may reset the processor or damage electronic components, resulting in interrupted
operations.
