Connecting the Module to the Motherboard
Note:
The system board used in the following illustrations may not resemble the actual one.
These illustrations are for reference only.
The extension module requires two cables, including the LPC cable and the power cable, to
connect to the motherboard for additional COM/Parallel ports via the LPC connector. The illus-
tration of connecting the extension module to the motherboard is shown below.

The 25-pin connector is used to connect an external parallel port. The parallel port connects
your PC to a parallel printer. It supports SPP, ECP and EPP.
SPP
(Standard Parallel Port)
Allows normal speed operation but in one
direction only.
ECP
(Extended Capabilities Port)
Allows parallel port to operate in bidirectional
mode and at a speed faster than the SPP’s data
transfer rate.
EPP
(Enhanced Parallel Port)
Allows bidirectional parallel port operation at
maximum speed.
