2. If the message is received incorrectly it will send “-” (02Dh) followed by “CR” (00Dh)

9.3 Protocol

9.3.1 Set-Function Listing

The PC can control the TV/DS for specific actions. The Set-Function command allows you to control the TV/DS behavior in a remote site through the RS232 port. The Set-Function packet format consists of 9 bytes.

Set-Function description:

Length: Total Byte of Message excluding "CR".

TV/DS ID Identification for each of TV/DS (01\~98; default is 01)

ID "99" means to apply the set command for all connected displays. Under such circumstances, only ID#1 display has to reply.

The TV/DS ID can be set via the OSD menu for each TV/DS set.

Command Type Identify command type,

"s" (0x73h): Set Command
“+” (0x2Bh): Valid command Reply
“-” (0x2Dh): Invalid command Reply

Command: Function command code: One byte ASCII code.

Value[1\~3]: Three bytes ASCII that defines the value.

CR 0x0D

Set-Function format

Send: (Command Type="s")

For VT2405LED-1 and VT3205LED, the set "Power on" command is the exception.

Reply: (Command Type="+" or "-"')

1. The reply for "Power on" command is the exception for VT2405LED-1 and VT3205LED. It's 0x322B0D (2+).
2. When PC applies command to all displays (ID=99), only the #1 set needs to reply by the name of ID=1.

Example1: Set Brightness as 76 for TV-02 and this command is valid. Send (Hex Format)

NOTE:

1. Behavior at lock modes

Lock Mode	Behavior
Button Lock	1. Lock all buttons on the front panel and RCU, except for “Power”.2. All the SET functions should be workable via RS32, even the ones with according hot key in RCU like Mute,...etc.
MENU Lock	1. Lock “MENU’ key of front panel and RCU.2. The Factory and Hospitality modes should not be blocked for the model using MENU-combined key to enter these two modes. Alternative approach will be indicated separately if any limitation by model.
POWER Lock 1.	Lock “POWER” key on the front and RCU.2. The SET_POWER on/off should be workable via RS232, but does not mean the POWER lock will be released under this case.3. Can not be unlocked by reset in OSD setting.4. Will auto AC power-on in power-lock5. Under power-lock, the set will not enter power saving when no PC signal and neither not turn off when no other video signals after 15min.
Remote control disable	Lock the RCU keys, but keep the front panel buttons workable.

9.3.2 Get-Function Listing

The PC can interrogate the TV/DS for specific information. The Get-Function packet format consists of 9 bytes which is similar to the Set-Function packet structure. Note that the "Value" byte is always = 000

Get-Function description:

Length: Total Byte of Message excluding "CR".

“-” (0x2Dh): Invalid command Reply

Command: Function command code: One byte ASCII code.

Value[1\~3]: Three bytes ASCII that defines the value.

CR 0x0D

Get-Function format

Send: (Command Type="g")

NOTE: Get "Power STBY status" is the exception for VT2405LED-1 and VT3205LED.

Reply: (Command Type="r" or "--")

If the Command is valid, Command Type = "r"

NOTE: The reply for "Power STBY status" command is the exception for VT2405LED-1 and V3205LED. It's 0x36 72 6C 30 30 30 0D (6rl000).

If the Command is Not valid, Command Type="-"

9.3.3 Remote Control Pass-through mode

When PC sets the TV/DS to Remote Control Pass through mode, the TV/DS shall send a 7-byte packet (followed by "CR") in response to RCU button activation. Note, that in this mode the RCU shall have no effect on the TV/DS function. For example: "Volume+" will not change the volume in the LCD but only sends "Volume+" code to PC over the RS232 port.
