Mt3-II Configuration Switch Assignments
Note: Be careful when changing switch settings. Carefully use a pointer on the lever of the switch you wish to
change. DO NOT use a lead pencil as this may contaminate the switch. DO NOT use a screw driver or
apply excessive force.
The RS232C Interface signals for the Mt3-II Series printer are terminated on a 6 PIN RJ type data connector
located on the side of the printer.
Six connections are provided from the Serial Interface to the host computer. The table below lists the Serial
Interface signals and pin outs on the RJ connector. A drawing showing the connector pin locations is also
provided.
The configuration switches SW1, SW2, and SW3 should all be set to OFF. Also the settings for the Baud Rate,
and Parity (SW4-7) must be set to match the host device settings.
