21 Chapter 2 Installation
2.23 AC'97 interface Connector (CN17)PCI-6886 can support separate independent PCI functions for Audio and
Modem, which is compliant to AC'97 Version 2.2 standard.
The AC'97 interface is a 5 x 2 pin box header. The PCI-6886 can support
Audio with the addition of optional PCM-231A-00A1. Detailed pin
assignment refer to Appendix B.
2.24 DIO connector (CN2) The PCI-6886 supports DIO interface by CN2, which is a 5 x 2 dual line
pin header, supply 8 general purpose input or output ports.
One characteristic of digital circuit is its fast response to high or low sig-
nal. This kind of response is highly needed for harsh and critical indus-
trial operating environment.
Generally, Digital Input and Output are signals to control external devices
that needs On/Off circuit or TTL devices. Detailed signal assignment
refer to Appendix A.
2.25 SATA Connector (SA1, SA2) PCI-6886 can support Serial ATA by two COMAX C504C connectors
(SA1, SA2), data transfer rates up to 150 Mbyte/s, enabling very fast data
and file transfer, and independent DMA operation on two ports. It also
supports alternate Device ID and RAID Class Code option for support of
Soft RAID.
