Manually Determining RS-232 Codes
When attempting to determine a specific command se-
quence for the Maestro M2e, it is sometime helpful to con-
nect the Maestro M2e to a terminal emulator program (like
Hyperterminal) and utilize the information from the Re-
ceiving Command. Physically perform the function on the
Maestro M2e (ie. adjust the volume knob, select a source,
change a surround effect), your Maestro M2e will transmit
a Receiving Command and you can use the command on
your screen to determine the specific RS-232 command.
