The Parallel Connection needs a Centronics IEEE 1284 cable with a 36-
pin male connector for unidirectional (forward channel) communications,
or an IEEE 1284 Compliant cable for bi-directional communications
(forward and reverse channels). Also, for bi-directional communications
your host must have supporting software. See Section 5 for more
information.

The USB Connection needs a USB cable and is supported in Windows 95
and greater operating systems. Depending upon the operating system of
your host computer, installation requirements may differ slightly.

The Serial Connection needs a serial interface cable with specific pin-
outs for proper communications (part numbers and pin-outs are given,
below; contact your reseller to order). The interface supports RS-232C
communications via a DB-9 connector. Serial port settings are menu-
selectable and must match your host’s serial port settings; see Section 4.
