When using 3
rd
party RS-232 control systems it is necessary to configure the RS-232
control system communication settings to conform to the AH66T settings.

The command structure for the primary AH66T functions is different than the command
structure for the integrated tuner. Each command set is covered separately.
AH66T Control Command Structure (Primary Functions)
AH66T control commands follow the same basic structure. Commands are in all capitals
and the comma separation (44 in decimal or 0x2C in hex) is required.
Prefix: &AH66 - This is required for all command strings.
Command (CMD): This is required for all command strings. See the list on the
following pages.
Parameter # 1 (PAR1): This generally refers to a zone or a chassis.
Parameter # 2 (PAR2): This is usually the second part of the actual command - ON / OFF /
TOGGLE / QUERY, for example.
Parameter # 3 (PAR3): Used when adjusting BASS and TREBLE settings.
Carriage Return (<cr>): This is required for all commands. (0x0d or Decimal 13)
