10. RS232 Protocol 10.1. Introduction This document describes the hardware interface spec and software protocols of RS232 interface communication between ViewSonic Commercial TV / Digital Signage and PC or other control unit with RS232 protocol. The protocol contains three sections command: • Set-Function • Get-Function • Remote control pass-through mode ※ In the document below, “PC” represents all the control units that can send or receive the RS232 protocol command. 10.2. Description 10.2.1.
10.3. Protocol 10.3.1. 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) If we want to set all TV/DS settings, use the TV/DS ID “99”, and it will not have Reply command on this function.
Example2: Set Brightness as 176 for TV-02 and this command is NOT valid Send (Hex Format) Command Name Length ID Command Value1 Value2 Value3 CR Type 0x30 0x38 0x73 0x24 0x31 0x37 0x36 0x0D Hex 0x32 Reply (Hex Format) Name Length ID Hex 0x34 0x30 0x32 Command Type CR 0x2D 0x0D Set function table: Set Function Length ID Command Type Command Value Range Code (ASCII) Code (Hex) Comments (Three ASCII bytes) Power on/off (standby) 8 s ! 21 000: STBY 001: ON Controlled power status: ON o

This is the power up default on the Monitor.
10.3.2. 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”. TV/DS ID Identification for each of TV/DS (01~98; default is 01).

Get function table: Get Function Length ID Command Type Command Value Range Code (ASCII) Code (Hex) Comments (Three ASCII bytes) Get-Contrast 8 g a 61 000 ~ 100 Gets Contrast value Get-Brightness 8 g b 62 000 ~ 100 Gets Brightness value Get-Sharpness 8 g c 63 000 ~ 100 Gets Sharpness value Get-Color 8 g d 64 000 ~ 100 Gets Color value Get-Tint 8 g e 65 000 ~ 100 Gets Tint value Get-Volume 8 g f 66 000 ~ 100 Gets Volume value Get-Mute 8 g g 67 000: OFF
10.3.3. Remote Control Pass-through mode When the PC sets the TV/DS to Remote Control Pass through mode, the TV/DS will 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.

NOTE: 1. This IR-pass-through code is different from the RCU key code. 2. Special control sequence for POWER key under IR-pass through mode. 2-1. When TV/DS is OFF and receives the IR POWER code: TV/DS will turn itself on, then forward the POWER code to the host via RS232. 2-2. When TV/DS is ON and receives the IR POWER code: TV/DS will forward the POWER code to the host via RS232, then turn off itself. 2-3.
