8.5.4. Query RS-232 baud rate
Description: The RS-232 baud rate can be checked. It works via LAN and RS-232 as
well, but if RS-232 is used the command has to be sent with the appropriate baud rate.
Command {RS232BAUD=?}
Response (RS232BAUD=<rate>)CrLf
Explanation: The router communicates with 57600 baud on the RS-232 port.
Info: RS-232 Baud rate can be checked and set on the front panel LCD menu as well.
8.5.5. Change RS-232 baud rate
Description: The RS-232 baud rate can be set. If RS-232 connection is used, the
command has to be sent with the earlier baud rate but the response comes with the new
baud rate.
Command {RS232BAUD=<rate>}
Response (RS232BAUD=<rate>)CrLf
Explanation: The router RS-232 port is set to 9600 baud.
Possible settings:
Info: RS-232 Baud rate can be checked and set on the front panel LCD menu as well.
8.5.6. Query control protocol
Description: Matrix routers can be controlled with different control protocols. This
command queries the active protocol for the used control interface.
Info: Be aware that different control interfaces can be set to use different protocols. E.g. the
Ethernet interface can use the Lightware protocol while the Serial interface uses
Protocol#2 at the same time.
Info: The response shows only the active protocol for the interface that was used to send the
command!
Command {P_?}
Response (CURRENT●PROTOCOL●=
Explanation: The matrix communicates with Lightware protocol.
Possible settings:
Info: Control protocol for each interface can be checked by the front panel buttons (section
Error! Reference source not found.) or on the front panel LCD menu as well.
