3. Parallel Printer Connector (26 Pin Block)
Connection for the included parallel port ribbon cable with mounting
bracket. Connect the ribbon cable to this connection and mount the
bracket to the case on an open slot. It will then be available for a
parallel printer cable. Note: Serial printers must be connected to the
serial port. You can enable the parallel port and choose the IRQ through
BIOS Setup on page 37 "Onboard Parallel Port." (Pin 26 is removed
to prevent inserting in the wrong orientation when using ribbon
cables with pin 26 plugged).
4. Serial port COM1 and COM2 connectors (Two 10-pin blocks)
These connectors support the provided serial port ribbon cables with
mounting bracket. Connect the ribbon cables to these connectors and
mount the bracket to the case on an open slot. The two serial ports on
the mounting bracket will then be used for pointing devices or other
serial devices. See page 36 for BIOS configuration of "Onboard Serial
Port". (Pin 10 is removed to prevent inserting in the wrong
orientation when using ribbon cables with pin 10 plugged).
