Getting Started 1

Configuring the Serial Port for Communications

You need to configure the serial port of the printer to match the configuration of your PC or network controlling device. If the printer’s default settings do not match, use the DIP switch settings table to configure the serial port.

To configure the printer serial port

1.Use the following DIP switch setting descriptions and table to locate the DIP switches you need to change to configure the serial port.

2.Use a small straight-slot screwdriver to set the appropriate DIP switches.

For example, if you want to change the media type to thermal transfer, set DIP switch 8 on the bottom bank of switches to the on position.

3.Turn the printer power off and then on for the configuration changes to take effect.

Note: Ignore Multi-Drop switches if you are not using a Multi-Drop network.
