LOCAL CONTROL PANEL OPERATION
Control via 9-pin Connectors
The 9-pin connectors allow you to control the routing switcher via an external
computer. On some switcher models, the serial port can be changed internally for
RS422 configuration (RS232 is factory configuration).
Each routing switcher model has one port and it is labeled on the back panel as
“RS232/422 Control” (refer also to the illustrations of back panels shown in
Chapter 1):
Connection to the RS-232/422 port is made using a standard 9 pin (pin
to pin) cable.
Conversion to RS-422:
To convert the RS-232 serial control to RS-422, remove top cover of router.
Locate the processor board on the rear of the front panel. The jumpers are
located in approximately the center of the processor PCB.The jumpers are
labeled JP1, JP2, and JP3.
Jumper positions are as follows:
