RS232 Protocol
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 sent or
receive the RS232 protocol command.

• Stop Bits: 1 (fixed)
2.3 Command Message Reference
PC sends to Monitor command packet followed by “CR”. Every time PC sends
control command to the Monitor, the Monitor 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)
