How to get information about the Matrix3's status.
Ping Messages
The Ping command is used to determine the basic status of a processor within a Matrix3 system. The status reply
includes two 7-bit values, "UserValue1" and "UserValue2", which both default to 0. These are optional values and
do not need to be set unless you want your own user values. For instance, they may be used to designate a show
project file version number.
The following command may be sent to any LX-300 in a system via a serial or TCP/IP port. The Ping Response is
sent on the same serial port as the ping was received on.
