NETWORK SETUP of AVR-4306/AVC-4320
>Procedure of Network Setup mode.
(1)Press SYSTEM SETUP button, then System Setup Menu appears on FL-display(and OSD)
(2)Select Network Setup.
(3)Set parameters described below.
<DHCP> "ON"---Use this setting when DHCP server is on the local network.
"OFF"---Use this setting when DHCP server is not on the local network.
<IP Address> When <DHCP> sets "OFF”, please set IP address.
When <DHCP> sets "ON”, you can confirm the IP address that is set by server.
<Subnet Mask> When <DHCP> sets "OFF”, please set Subnet Mask.
When <DHCP> sets "ON”, you can confirm the Subnet Mask that is set by server.
<Gateway> Set the address of Gateway when Gateway is on the local network.
Do not set this parameter when Gateway is not on the local network.
<Primary DNS> Do not set this parameter.
<Second DNS> Do not set this parameter.
<Proxy> Set this parameter "OFF".
<Network Option:Standby Mode Power Saving>
“OFF”---Use this setting when using the AVR-4306/AVC-4320 connected in a network.
“ON”--- Use this setting when not using the AVR-4306/AVC-4320 connected in a network.
This setting is reducing the power consumption in the standby mode.

Protocol specification
The following three data forms is 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

5/28
The example of a command * <CR> is the meaning of 0x0D.
SIDVD<CR> : Select Input source DVD
MSSTEREO<CR> : surround Mode Set to STEREO
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 defines “99”.
J) If the MASTER VOLUME & CHANNEL VOLUME set with 0.5dB step, the PARAMETER (with COMMAND and RESPONSE, EVENT) defines three
ASCII characters as bellows.
ex. MASTER VOLUME = +1.0dB : MV81<CR>
+0.5dB : MV805<CR>
0dB : MV80<CR>
-0.5dB : MV795<CR>
-1.0dB : MV79<CR>
| |
-79.5dB : MV005<CR>
-80.0dB : MV00<CR>
--- : MV99<CR>
* At the **.0dB step, only uses two ASCII characters as PARAMETER, same as usual.
K) Four seconds later, please transmit the next COMMAND after transmitting a power on COMMAND（PWON).
