=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.

====RS-232 Communication Setting====
* Baud Rate Select: 9600bps (fixed)
* Data bits: 8 bits (fixed)
* Parity: None (fixed)
* Stop Bits: 1(fixed)
====LAN Communication Setting====
* Type: Ethernet
* Protocol: TCP/IP
* Port: 5000 (fixed)
* Cross subnet: No
* Logon Credentials: No
====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:
# If the message is received correctly it will send “+” (02Bh) followed by “CR” (00Dh)
# 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:'''
