Parallel-Port Interface
The EPIC/PM incorporates an IBM XT/AT compatible parallel port. It supports uni-directional, bi-
directional, EPP and ECP operating modes.
Connector
The parallel port is available through the standard DSUB25 connector which is part of the
multifunctional Connector X1 on the front. To find the location of the parallel port, please see the
Appendix E: Connector Layout chapter.
The following table shows the pin-out of the connector.

Notes: (*) To protect the external power lines of peripheral devices, make sure that:
-- the wires have the right diameter to withstand the maximum available current
-- the enclosure of the peripheral device fulfils the fire-protecting requirements of IEC/EN 60950.
To find the location of the parallel port, please see the Appendix E: Connector Layout chapter.
13.2 Configuration
The parallel-port mode, I/O addresses, and IRQs are changeable from the BIOS Setup Utility. You can
program the base I/O-address 378h (default), 3BCh or 278h. You can set the parallel port mode to
disable, enable or AUTO (default). You can choose IRQ5 or IRQ7 as the parallel-port interrupt.
Refer to the I/O Device Configuration Submenu in the Appendix B: BIOS Operation chapter for additional
information on configuration.
