Control via 9-pin Connectors
The 9-pin connector allows 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).
Conversion to RS-422
To convert the RS-232 serial control to RS-422, Contact the Sierra Video factory.
Serial Port Wiring
The serial port on the Series 32 routing switcher is as follows;
PC RTR *RTR Alternate Wiring (Older Units)
2 RX 2 TX 2 TX
3 TX 3 RX 8 RX
5 GND 1 & 9 GND 1 GND
Host Mode
Series 32 routing switchers has one 9-pin RS232 connector set to factory default as Host
protocol.
The Host port allows you to control the switcher using a standard personal computer or other
external devices (such as Creston or AMX). The switchers are shipped in the “Host” mode but
can be changed to the “Terminal” mode by the following procedure:
 Connect a terminal to the serial port and send the following command:
**HOST0!!
The port now uses the terminal protocol.
 To restore back to the Host port, send the following command:
**HOST1!!
Terminal Mode
The 9-pin serial connector can be used for simple terminal control, (V=T100 emulation capability).
The terminal performs the following functions:
Serves as an overall system controller
Sets up the personality of the entire system (size, level control, change
names, mapping, etc.)
These setups are stored in non-volatile memory so that a terminal is not required unless it is
necessary to change a setup.
Power Up
Once all signal and control connections have been made, turn on the power switch. AC to the
router is indicated by an illuminated power switch button. On power up, the controller will restore
the routing switcher to the last state it was in before the power was turned off including all
configuration settings as well as crosspoint switcher status.
Note:
If the audio frame option is configured- The Audio frame must be powered on BEFORE the
power is applied to the Video frame.
