Notes

• Command format: <CR>*<command>=<value>#<CR> where <CR> is carriage return (0x0D). Some commands (zoom, navigation, auto, reset, and quick cooling) omit the =value portion or the # terminator as documented.
• Case insensitive — uppercase, lowercase, and mixed case accepted for all commands.
• Error responses: Illegal format (malformed command), Unsupported item (valid command not supported by model), Block item (command cannot execute under current conditions).
• Commands require standby power of 0.5W or a supported baud rate to be set.
• "Support" column in source indicates model-specific availability (YES/NO); all commands are documented regardless of per-model support.
• When controlling via LAN (TCP), commands must include <CR> delimiters; behavior is identical to serial control.
• HDBaseT control routes RS-232 through the HDBaseT connection with identical serial settings.
