    RS-232

    This document describes the hardware interface spec and software protocols of RS-232 interface communication between ViewSonic LFD and PC or other control units with RS-232 protocol.

    The protocol contains three command sections:

    • Set-Function
    • Get-Function
    • Remote control pass-through mode
    NOTE: Below, “PC” represents all the control units that can send or receive the RS-232 protocol command.

    Description

    • Parity: None (fixed)
    • Stop Bits: 1(fixed)

    LAN Communication Setting

    Command Message Reference
    PC sends to LFD command packet followed by “CR”. Every time PC sends control command to Display, the Display shall respond as follows:

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

    Protocol

    Set-Function Listing

    The PC can control the Display for specific actions. The Set-Function command allows you to control the Display behavior at a remote site through the RS-232 port. The Set-Function packet format consists of 9 bytes.

    Set-Function Description:

    Length Total Byte of Message excluding “CR”
    LFD ID Identification for each of Display (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 LFD ID can be set via the OSD menu for each Display.
    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")

    NOTE: When PC applies command to all displays (ID=99), only the #1 set needs to reply by the name of ID=1.


    Example 1: Set Brightness as 76 for Display (#02) and this; command is valid.

    The display will send out the updated data/status automatically without getting a query from the host whenever the following data/status is changed by the user through any of the available ways like: remote control unit, front keys, or touch screen.

    • Power On/Off
    • Input Select
    • Brightness
    • Backlight
    • Volume
    • Mute On/Off

    Remote Control Pass-Through Mode

    When the PC sets the Display to Remote Control Pass through mode, the Display shall send a 7-byte packet (followed by “CR”) in response to remote control unit (RCU) button activation. In this mode the remote control shall have no effect on the Display function. For example: “Volume+” will not change the volume of the Display, but instead only sends the “Volume+” code to the PC over the RS-232 port.
