Protocol specification

The following three data forms are defined.

COMMAND : The message sent to a system(POA) 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 (POA)

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 (POA)

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

PA :Power AMP（POA）Control

PARAMETER ：ASCII CODE (up to 25 characters)

EX.PWON ：Power On

Others

A) COMMAND is receivable also during transmission of EVENT.

B) The RESPONSE should be sent as opposed to the request command by all the commands with which an EVENT

exists not need to the another request commands.

C) Please set the input channel after setting the power amp.

D) Please Power on it after making the CONTROL switch of POA-A1HD EXTERNAL
