the parallel port). The MIC-3351 includes an on-board parallel port,
accessed through a DB 25-pin connector, CN8, on the front panel.
The parallel port is designated as LPT1 and can be disabled or
changed to LPT2 or LPT3 from the system BIOS setup.
2.6 PS/2 Keyboard and Mouse Connector (CN3)
The MIC-3351 provides a 6-pin mini-DIN connector (CN3) on the front
panel for connection of PS/2 keyboard and PS/2 mouse. The MIC-3351
comes with an cable to convert from the single 6-pin mini-DIN connec-
tor to a double PS/2 keyboard connector and PS/2 mouse connector.
Since these two connectors are identical, please follow the icons on
the cable to plug the keyboard and the mouse into their correct
connectors.
2.7 Serial Ports (CN2)
The MIC-3351 offers two serial ports in micro-formats: COM1 and
COM2, both in RS-232. These ports allow users to connect to serial
devices (a mouse, printers, etc.) or a communication network. Advan-
tech provides two serial-port cables shipped with the MIC-3351.
These cables are designed to convert micro-format serial ports to
standard-format serial ports which are normally be seen on desktop
PCs.
You can select the address for each port ( For example, 3F8H [COM1],
2F8H [COM2]) or disable it, using the BIOS Advanced Setup program,
covered in Chapter 6.
Different devices implement the RS-232 standard in different ways. If
you are having problems with a serial device, be sure to check the pin
assignments for the connector.
The IRQ and address range for both ports are fixed. However, if you
wish to disable the port or change these parameters later, you can do
this in the system BIOS setup. The table on the next page shows the
settings for the MIC-3351 board's ports:
