7.5.4. Querying the RS-232 Baud Rate
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 and Response #rs-232
ȩ {RS232BAUD=?}
Ȩ (RS232BAUD=<rate>)CrLf
Example
ȩ {rs232baud=?}
Ȩ (RS232BAUD=57600)CrLf
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.
7.5.5. Changing the RS-232 Baud Rate
DIFFERENCE:
This function has been heavily modified in MX-CPU2 compared to CPU1.
The RS-232 baud rate can be set. If the 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 and Response
ȩ {RS232BAUD=<rate>}
Ȩ (RS232BAUD=<rate>)CrLf
Parameters
The possible values of <rate>: 9600, 19200, 38400, 57600 (default), 115200.
Example
ȩ {rs232baud=9600}
Ȩ (RS232BAUD=9600)CrLf
INFO:
RS-232 Baud rate can be checked and set on the front panel LCD menu as well.

7.5.6. Querying the Control Protocol
DIFFERENCE:
This function has been heavily modified in MX-CPU2 compared to CPU1.
Matrix routers can be controlled with different control protocols. This command queries the active protocol
for the used control interface.
ATTENTION!
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.
Command and Response
ȩ {P_?}
Ȩ (CURRENT•PROTOCOL•=•#<protocol>)CrLf
Parameters
Example
ȩ {p_?}
Ȩ (CURRENT PROTOCOL = #1)CrLf
The matrix communicates with Lightware protocol.
The response shows only the active protocol for the interface that was used to send the command. Control
protocol for each interface can be checked with the front panel buttons (see the
or in the front panel LCD menu.
7.5.7. Changing the Control Protocol
DIFFERENCE:
This function has been heavily modified in MX-CPU2 compared to CPU1.
Matrix routers can be controlled with different control protocols. This command sets the active protocol only
for the currently used control interface. The setting applies only to the interface that was used to send the
command! The USB interface always uses the Lightware protocol, this cannot be changed.
Command and Response
ȩ {P_<protocol>}
Ȩ (PROTOCOL•#<protocol>•SELECTED!)CrLf
Parameters
Identifier Parameter description Parameter values
<protocol> Currently active 1: Lightware (default)
protocol 2: Protocol #2
3: LW simple (not in use)
Identifier Parameter description Parameter values
<protocol> Currently active 1: Lightware (default)
protocol 2: Protocol #2
3: LW simple (not in use)
