Introduction

This document provides information and procedures for using serial commands (ASCII text messages) to control the product.

RS232 communication parameters

The RS232 IN port has several communication parameters.
Parameter
Default baud rate
Parity
Data bits
Stop bits
Flow control
Serial port baudrate: 115200 (38400 in stby, used for WAKEUP command), 8 data bits, no-parity, 1 stop bit.
Baud Rates:
115200 used for RS232/LAN ASCII commands
38400 used for "WAKEUP" command only during standby
19200 used for UART0
9600 used for UART1

Connecting to the RS232 port

Use an RS232 connection to remotely access display controls and image setups, issue commands or queries, and receive replies.
1. Connect one end of a straight through DB9 connector serial RS232 cable to the display panel RS232 port.
2. Connect the other end of the cable to a computer.

Setting up terminal programs

Learn how to configure terminal programs for proper echoing.
When using any terminal program other than PuTTy, you must include a carriage return (\r) and a line feed (\n) after all API commands.
Configure the settings for your terminal program.

Important Notice: The Secure II Series panel has a built in Pin to comply with the California law requiring Internet connected devices to
include reasonable security features (California Civil Code Section 1798.91.04).
The Network and Serial connection will require a command that will unlock the Serial and Ethernet connection. This command needs to be
resent if the panel loses power or if the main power switch is turned OFF.
Once a connection is established with a Serial or Ethernet connection send this command to unlock the port "SETUSERSECLEVEL ADMIN
