Communication Interfaces

The printer supports serial communications with the following EIA interfaces:
RS-232C, RS-422, RS-485.
RS-232C The RS-232C serial interface is used in all asynchronous point-to-
point full- or half-duplex direct data communications or modem control. The
cable connected to the printer must have the pin assignments listed in the
following table to operate properly under RS-232.
RS-422 The RS-422 interface is used in long line point-to-point direct connect
installations. The cable connected to the printer must have the pin assignments
listed in the following table to operate properly under RS-422.
RS-485 The RS-485 serial interface is used for multi-drop installations only.
The cable connected to the printer must have the pin assignments listed in the
following table to operate properly under RS-485.
