Connecting a CP local operator terminal cable
Connect a local operator terminal to a Passport 15000 or 20000 to enable
local communication with the switch during commissioning. You can use this
terminal to set up a connection to your network management system.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• The operator cable is intended only for commissioning the switch and
must not remain hooked up permanently.
• The operator terminal must be installed and located in the same room as
the node. Refer to preparing the site and selecting the type of operator
terminal in 241-1501-205 Passport 15000, 20000 Site Requirements and
Preparation Guide.
• You need a computer terminal interface cable with PEC NTBP25 or
alternatively have a spool of interface cable and the appropriate end point
connectors at hand before starting the procedure.
Procedure steps
1 Ensure the settings on the terminal match the output of the CP module at
9600 bit/s, 1 stop bit, and no parity. Refer to the terminal manufacturer’s
instructions on how to do this.
2 Unpack the RS232 CP cable with PEC NTBP25. Otherwise, at the end of
the spool of RS232 interface cable, attach a V.24 DCE connector
according to the instructions that came with the connector.
3 Connect the V.24 DCE connector into the active CP faceplate at the
RS232 connector labeled P1.
4 Route the interface cable from the CP faceplate up to the connector on
the terminal.
5 At the terminal end of the interface cable, cut the interface cable so that it
can accommodate a connector and plug into the terminal without
straining the connection.
6 At the terminal end of the interface cable, attach a 9-pin D-sub connector
to the cable according to the instructions that came with the connector.
7 Connect the D-sub connector into the terminal. Ensure there is no stress
on the cable or connector, nor a right-angle bend.
