Configuring the serial interface settings
Configure the control system or computer’s serial interface before sending commands to the display.
To configure the serial interface settings
1. Turn on the display.
2. Turn on the control system or computer, and access the serial data communications settings.
3. If using a terminal emulation program on a computer, activate local echo.
4. Configure the serial interface settings using the following values, and then press ENTER.
Baud rate 19200
Data length 8
Parity bit None
Stop bit 1
When a command prompt (>) is received by your control system or terminal emulation program, the
display can accept commands. If the command prompt isn’t received, send a carriage return character
(0x0d) to the display (press ENTER on your keyboard if you’re using a terminal emulation program on
your computer).
NOTE
If no message or an error message is received in the control system or terminal emulation program,
the serial interface isn’t configured correctly. Repeat steps 3 and 4.
Communication structure
Communication consist of a command argument, property affected, operator symbol, a value to apply, and a
terminating carriage return character (0x0d).
IMPORTANT
When manually entering commands into a terminal emulation program, commands must be terminated
with only a carriage return character (0x0d). If you terminate a command with both a carriage return
character (0x0d) and a line feed (0x0a), the command may not be processed and the command prompt
that indicates readiness to receive the next command may not be received.
