Protocol specification

The following three data formsis defined.

COMMAND : The message sent to a system(AVR/AVC) 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/AVC)

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/AVC)

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

CDR/TAPE-1 : function name

THX SURROUND EX : surround mode name

SUPER STADIUM : surround mode name

*Special Parameter--- ? : for request command

-3-

The example of a command * <CR> is the meaning of 0x0D.

SIDVD<CR> : Select Input source DVD

MSTHX SURROUND EX<CR> : surround Mode Set to THX SURROUND EX

MVUP<CR> : Master Volume UP

PWON<CR> : system PoWer ON

PWSTANDBY<CR> : system PoWer STANDBY

SI?<CR> : Request command for now playing input source >> Return RESPONSE ‘SI***<CR>’

Others

A) COMMAND is receivable also during transmission of EVENT.

B) Since CHANNEL VOLUME changes simultaneously when the SURROUND MODE changes, the value of the channel volume of all channels

returns as EVENT.

C) CHANNEL VOLUME returns the data of ALL channels by the present SURROUND MODE also including an intact channel. In this case,

the data of an intact channel is set to "50".

D) Since SURROUND MODE changes simultaneously when the INPUT source changes, the SURROUND MODE (and also the value of the channel

volume of all channels , It described in B) ) returns as EVENT.

E) When SURROUND MODE is the same in between INPUT source change before and after, EVENT of SURROUND MODE and CHANNEL VOLUME

does NOT return.

F) Although EVENT of SURROUND MODE returns when the present SURROUND MODE is set up again, CHANNEL VOLUME does NOT return.

G) When SURROUND MODE is changed, before returning SURROUND MODE after change as EVENT, the present SURROUND MODE is returned.

H) 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(ex. SV command).

I) The PARAMETER (with COMMAND and RESPONSE, EVENT) of minimum level of MASTER VOLUME and MULTI ZONE defines “99”.
