RS232 HEX Commands
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.
Error Responses
•
NAK reply: 15
When the display cannot understand the received command, it returns this value. In
such a case, check the sending code and send the same command again.
•
Error reply: 1C 00 00
When the display cannot execute the received command for any reasons, it returns
this value. In such a case, check the sending code and the setting status of the display.
