The command string "*** RCM-26 command mode entered ***" is sent to RS-232 after powering on the remote amp and
after a short initializing period. The RS-232 interface is now ready for communication.
ASCII CONTROL PROTOCOL
A simple ASCII string protocol, which is referred to as ASCII Control Protocol is implemented in the remote amps.
Commands are organized in a tree structure with up to 6 levels. The slash "/" or a space " " can be used for separation.
The question mark "?" can be utilized to query parameter settings or commands of the corresponding level. To step one
level down you have to enter "../".
The following table lists the ASCII Control Protocol commands with brief explanations.
