ASPEN 1616 AND 3232HD/SDI 3G ROUTING SWITCHER
43
Control via 9-pin Connectors
The 9-pin connectors allow you to control the routing switcher via an external computer.
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 panels 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
addresses 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.
