RS-422/RS-485 Interconnections
An interface adapter is required to connect the printer’s RS-232 DB-9 interface to a
host computer through an RS-422 or RS-485 interface. A generic DB-25 adapter can
be used.
This illustration shows the cable wiring for interconnecting the DB-9 to the interface
adapter’s DB-25 female connector.
Caution •
A qualified service technician must install a jumper on the printer’s main
logic board at JP1, pins 2 and 3, for the RS-422/RS-485 interface adapter to function
properly.
