2.3.2.2. Dip Switches
By turning on the printer while pressing the Cut button, the LR3000 will print a
Quick Reference Table with the LED Error Codes and a Table with Dip Switch
Configuration for the serial interface.
If you have the version with the serial interface card, the integrated Dip Switches
will allow you to make quick changes to the settings, like communication settings,
handshaking, parity check, data bits, and stop bit.
If you want to make changes follow the steps below.
Make sure the printer is switched off.
If you want information about the options you have with the Dip Switches, make a
print before switching off again. Turn off the printer first and close the cover if it is
open. Make sure there is paper in the printer. Then press and hold the PAPER CUT
button while you switch the printer on again. When the printer starts printing,
release the PAPER CUT button and a table for the Dip Switch settings will be printed.
Pull the interface card out of the card slot.
With the COM 1 Card, the easiest way is to grab and pull the connector of the
interface cable with the screws fastened to the interface card; the whole interface
card should come out.
You will find the Dip Switches on the board, as shown by the picture below.
