RS-422A interface

The serial interface was set to RS-232C mode before leaving the factory. However, by changing the

jumper connector on the IB-10 interface board, the interface can be changed to RS-422A mode.

In RS-232C mode, the printer can be connected to a personal computer (or similar device)

equipped with an RS-232C serial interface. (The serial interface is set to RS-232C before

leaving the factory.)

In RS-422A mode, the printer can be connected to a personal computer (or similar device)

equipped with an RS-422A serial interface.

Note______________________________________________________________________

The changing of the jumper connector should be carried out only by a Kyocera authorized dealer or

Kyocera certified technician. Kyocera shall not be liable for damage due to improper changing of the

jumper connector.
