Interface type and parity

If your computer is set up for serial communication, you need to change DIP switches 2-5 and 2-6 so that your printer and computer can communicate properly. These two DIP switches control the interface type and parity. (You may also need to select a different baud rate. See the following section on baud rate.)

The table below shows the DIP switch settings for a parallel interface, and for a serial interface with odd, even, or no parity. If you don’t know what type of interface your computer requires, check your computer manual. Also check your computer manual to make sure your computer and printer have the same parity setting.

Baud rate

Besides selecting serial interface and parity, if your computer is set up for serial communications you may also need to change the baud rate setting. Baud rate is the rate at which the printer receives data from the computer.

The table below shows the DIP switch settings for the printer’s four baud rate settings. Check your computer manual or application program for the correct baud rate setting. Your computer and printer should always be set to the same baud rate.
