Built-in Ports
The 586STC system board is equipped with two serial ports, one paral-
lel printer port, one shrouded floppy disk header, two shrouded IDE
hard disk headers and one PS/2 mouse port. Refer to page 12 for the
locations of the built-in connectors and pin 1 of those connectors.
Serial Ports
The 586STC is equipped with two serial ports at locations J10 (COM 2)
and J8 (COM 1) of the system board. These built-in serial ports are RS-
232C asynchronous communication ports with 16C550A-compatible
UARTs that can be used with modems, serial printers, remote display
terminals, and other serial devices. They use the following system I/O
addresses:
Connecting the Serial Ports
Two serial port cables are provided with the system board. Connect a
serial port cable to connector J8 on the system board for COM 1 pri-
mary serial port. Connect the other serial port cable to connector J10
for COM 2 secondary serial port. Make sure the colored stripes on the
ribbon cables are aligned with pins 1 of connectors J8 and J10. Mount
the card-edge bracket to the system chassis.
PS/2 Mouse Port
The PS/2 mouse port is a 6-pin connector on the system board. Attach
the 6-pin mouse port cable, which is mounted on a card-edge bracket,
to connector J7. Make sure the red wire on the PS/2 mouse connector
is aligned with pin 1 of connector J7.
