these commands are beyond the scope of this document. Intended for advanced
users, these messages allow the RX 400p to be configured and monitored remotely.
A separate RX 400p Programming Manual is available that goes into detail on how to
use these extended commands. Please contact MID-TECH for further information on
programming the RX 400p through its serial port.
