Protocol Test Steps
• Before testing, please know the board type you have. There are two types of board. The UART 0 and UART
1 connections of the these boards are explained below:
1. RJ12 is connected to UART 0, DSUB9 is connected to UART 1. Therefore, UART 0 and UART 1 could
be tested separately in this type of the board
2. RJ12 and DSUB9 both are connected to UART 0. UART 1 is supported for OPS module but not
reachable. Therefore, only UART 0 could be tested in this type of the board.
• Activate HEX protocol on Display.
a. Enter Signage Settings Menu.
b. Change ASCII option to HEX in UART 0 or UART 1 sub-menu item
• Open any serial port communications program (e.g Realterm). Configure serial communication settings as
below:
Baud Rate : 19200 for UART0, 9600 for UART1
Parity : None
Data Bits : 8
Stop Bits : 1
Handshake : None
• Note that UART0 default value: ASCII, UART1 default value: HEX
In the tables given below, XY represents are variable byte.
All byte values are hexadecimal.
