RS-232 Serial Interface Connector Pin Assignments
The printer provides a 25-pin DB-25S connector on the right, rear
side panel for connection of a serial interface cable. This connector
is also used for the RS-422 serial interface. Selection of the desired
interface is determined by the position of the RS-232/422 switch
located on the right, rear side panel of the printer.
Table 8 lists the pin assignments of the RS-232 interface
connector.
