Denon AVR-2312 Protocol Guide

- 4 -
Protocol specification
The following three data forms are defined.
COMMAND  : The message sent to a system(AVR) from a controller(Touch Panel etc.)
A command to a system is given from a controller.
EVENT : The message sent to a controller (Touch Panel etc.) from a system (AVR)
The result is sent, when a system is operated directly and a state changes.
*The form of EVENT presupposes that it is the same as that of COMMAND.
**Refer to the following table for the contents of COMMAND and EVENT.
RESPONSE : The message sent to a controller (Touch Panel etc.) from a system (AVR)
if the ‘request command’ (COMMAND+?+CR(0x0D)) has came from a controller.
The RESPONSE should be sent within 200ms
of receiving the COMMAND.
*The form of RESPONSE presupposes that it is the same as that of EVENT.
Basic specification: The command by ASCII CODE, parameter expression
*ASCII CODE which can be used is from 0x20 to 0x7F: the alphabet and the number of 0-9, and space (0x20), some signs,
AND carriage return (0x0D) --- It is used only as a pause sign.
Command structure: COMMAND + PARAMETER + CR (0x0D)
COMMAND: ASCII CODE of 2 characters
Ex. SI : Select Input source
MS : surround Mode Setting
MV : Master Volume setting
PW : system PoWer setting
PARAMETER : ASCII CODE ( up to 25 characters)
ex. DVD : function name
SUPER STADIUM : surround mode name
*Special Parameter--- ? : for request command
