Interfacing To The Printer - Datamax Prodigy Plus Operator's Manual

2.3.1

Interfacing to the Printer

For most applications, the interface between the Printer and the host
device will be RS-232C. The interface cable is connected between the
Printer and the host via the DB-25 connector. The DB-25 connector is
labeled "serial" and is located on the back of the Printer. Several typical
cable interfaces are listed in Table 2-1.
The Printer supports both XON/XOFF and CTS/DTR handshaking. For
connection to most host systems, the XON/XOFF handshaking works to
reduce the number of wires needed in the interface cable. For interfacing
RS-422 devices, the XON/XOFF handshake is the only appropriate
method. Refer to Table 2-2 for the appropriate communications cable
needed for your configuration.
