PRINTER SETTINGS
Notes: (1) A USB keyboard is required to setup the printer.
(2) Ensure the printer’s RS485 settings and the PLC or PC’s com port settings are set to
the same values.
To configure the printer for RS485 communication:
(1) From the main menu, highlight Settings.
(2) Press the Enter button.
(3) Move the cursor to highlight RS485.
(4) Press the Enter button.
(5) The following settings can now be configured:
(6) Press ESC to return to the main menu.
End of procedure.
Status: Enable or Disable RS485 communication.
Address Set a unique address for each printer. The value is set in decimal form
from 1 to 255.
See “DECIMAL/HEXADECIMAL CONVERSION TABLE” on page 35.
Baud rate: Set the speed of communication from 9600 to 115200.
Parity: Set the protocol check sum:
•Odd
•Even
•None
Data bits Select 8 if Parity is set to None.
Select 9 if Parity is set to Odd or Even.
Stop bits Select 1 or 2

COMMUNICATION COMMANDS
Create Message and Start Printing Via RS485
The example below illustrates how to send the commands to set the font type, font size, message
