Setting the Control Port

Whichever control port is chosen, it must first be set up so the control

port switches match the communication parameters being used by the

control device. If using the rear–panel DTE control port, set the

shelf–address switch SA5 to “up” (leave the switch down for the

rear–panel DCE control port).

For more information, refer to the vendor user manual (part number

1174139) and installation manual (part number 1174462) provided with

each CSU.

Plug one of the cables listed below into the Control Port connectors:

Part Number Description of Cable

01–95006–022 (six feet) DB–9S to DB–9P

01–95010–022 (ten feet)

The control port cables can be used to connect the shelf to:

 A PC using the AT 9–pin interface

 A modem using the 9–pin connector

 Other shelves in a daisy chain
