Control via 9-pin Connectors
The 9-pin connector allows you to control the routing switcher via an external computer
master router, or other controlling device. The serial port can be changed internally for
RS422 configuration (RS232 @ 9600 baud is factory configuration).
The routing switcher has one port labeled on the back panel as “RS232/422” (refer also
to the illustrations of back panel shown in
Chapter 1
):
Connection to the RS-232/422 port is made using a standard 9 pin (pin to pin) cable.
NOTE:
To convert the 9-pin connector to an RS422 serial port see the serial setup section.
Control via Ethernet
The crosspoints in the routing switcher may be controlled via Ethernet using the Host
Protocol. To control the routing switcher, establish a TCP/IP connection to the IP
address of the routing switcher using port number 10001. A communications program
such as telnet can be used to establish this connection. Once the connection is
established, sending the command
**!!
should cause the routing switcher to return ** OK
!!. This connection supports the entire Sierra Video Host protocol command set
supported by this model.
