Parallel port connector

Use this connector to connect a parallel device. The following illustration shows a
parallel connector.
The parallel connector supports three Institute of Electrical and Electronics
Engineers (IEEE) 1284 modes of operation: Standard Parallel Port (SPP),
Enhanced Parallel Port (EPP), and Extended Capability Port (ECP). If you configure
the parallel port to operate in bidirectional mode, it supports the EPP and ECP
modes of operation. To configure the parallel port, use the Devices and I/O Ports
option in the Configuration/Setup Utility program. See the User's Guide for more
information. If you configure the parallel port to operate in bidirectional mode, use
an IEEE 1284-compliant cable that does not exceed 3 meters (9.8 ft).

Serial-port connectors

Use a serial connector to connect a serial device. The following illustration shows a
serial connector.
