2.19.5 Power Button (Pin 9 & Pin10)
The PCI-6886 provides an ATX power input connector. When connected
with PIN 9 & PIN 10, it enables power On/Off from the chassis.
2.20 COM port connector (CN8,CN13,CN14)The PCI-6886 provides four serial ports (COM1,COM3,COM4: RS-232
and COM2: RS232/RS422/RS485). CN13 supports COM1, CN14 sup-
ports COM2, CN8 supports COM3, COM4. and JP1 is for COM2 RS232/
RS422/RS485 selection. It provides connections for serial devices (a
mouse, etc.) or a communication network. You can find the pin assign-
ments for the COM port connector in Appendix B.
2.21 MINI PS/2, KB/Mouse connector (CN19)The PCI-6886 board provides a keyboard connector that supports both a
keyboard and a PS/2 style mouse. In most cases, especially in embedded
applications, a keyboard is not used. If the keyboard is not present, the
standard PC/AT BIOS will report an error or fail during power-on self-
test (POST) after a reset. The PCI-6886’s BIOS standard setup menu
allows you to select "All, But Keyboard"under the "Halt On"selection.
This allows no-keyboard operation in embedded system applications,
without the system halting under POST.
2.22 External KB Connector(CN18)In addition to the Mini keyboard connector on the PCI-6886’s rear plate,
there is an additional onboard external keyboard connector, allowing for
greater flexibility in system design.
