2.15 Audio AC'97 Link interfaces (CN4)
The PCM-9587 is equipped with a high quality audio interface, which
provides 16-bit CD-quality recording and playback as well as OPL3 com-
patible FM music. It is supported by all major operating systems and is
completely compatible with Sound Blaster Pro.
2.15.1 Audio connector(CN4)
The PCM-9587 provides all major audio signals on a 16-pin flat-cable
connector, CN4. The audio signals include Microphone in (mono), Line
in (stereo), Line out (stereo) and Speaker out (stereo). You will need an
adapter cable if you use traditional jack connectors for these audio sig-
nals.
2.15.2 CD audio-in connector (CN3)
All CD-ROM drives can provide analog audio signal output when used as
a music CD player. The CN3 on PCM-9587 is a connector to input CD
audio signal into the audio controller. The audio cable of your CD-ROM
drive will be used to connect to CN3.
2.16 COM port connector (CN21)
The PCM-9587 provides four RS-232 serial ports (COM1,3,4:RS-232,
COM2: RS-232/422/485) in one COM port connector. The COM port
connector is a 40-pin, 20*2P 180D(M) 2.0mm, connector. It provides
connections for serial devices (a mouse, etc.) or a communication net-
work. You can find the pin assignments for the COM port connector in
Appendix C. COM2 can be configured to operate in RS-232,RS-422, or
RS-485 mode. This is done via J5.
2.17 VGA/LVDS interface connections (CN7, CN8,CN9)
The PCM-9587’s AGP SVGA interface can drive conventional CRT dis-
plays and is capable of driving a wide range of LVDS flat panel displays.
The board has three connectors to support these displays: one for standard
CRT VGA monitors, one for LVDS type LCD panels and one for DVI
type LCD panels.
2.17.1 CRT display connector (CN7)
