the router protocol. Lightware routers have a special protocol, but to
interoperate with third-party devices, a secondary protocol is also provided.
The supported LW2 commands are described in this chapter:

The matrix routers accept commands surrounded by curly brackets - { } - and responds data surrounded by
round brackets - ( ) - only if a command was successfully executed. All input commands are converted to
uppercase, but respond commands can contain upper and lower case letters as well.

* The command has the same arguments on the input ports and the output port, as well.

The MX-CPU2 processor board works with a similar but renewed protocol as the earlier generation matrix

Changing Protocols
The router is equipped with multiple router protocols. 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. The currently used protocol can be viewed or changed any time on the matrix
front panel (see the Control Protocols section) or by protocol commands.
