Key Commands
Key commands accomplish the same purposes as the previously covered commands but
use a different format. Key commands imitate the IR commands found in the IR Library.
Key Command Structure
Key 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.
Parameter # 1 (PAR1): KEY – This is required for all command strings.
Parameter # 2 (PAR2): Zone selection (ZZ). This is required for all command strings
Parameter # 3 (PAR3): Desired command (abcd). Expressed as a 4 digit number.
Carriage Return (<cr>): This is required for all commands. (0x0d or Decimal 13)
Sample Command Layout:
&AH66,KEY,ZZ,abcd<cr>
Key Command Response Structure
When a key command is sent the AH66T will generate a response that indicates whether or
not the command was successfully decoded.
When the AH66T successfully decodes key commands it will respond with *AH66,ACK.
If the key command is not successfully decoded (incorrect command or format) the AH66T
will respond with *AH66,NACK.
