IBM 100/10 User Manual

The PCM-9575 provides all major audio signals on a 16-pin flat-cable 
connector, CN4. These audio signals include Microphone in (mono), Line 
in (stereo), Line out (stereo), and Speaker out (stereo). If you use tradi-
tional telephone jack connectors for these audio signals, you will need an 
adapter cable. 

Any CD-ROM drive can provide analog audio signal output when used as 
a music CD player. The CN2 on PCM-9575 is a connector to input CD 
audio signals into the audio controller. The audio cable of your CD-ROM 
drive will be used to connect to CN2.

The PCM-9575 provides four 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, dual-inline, male header. It provides connections for serial 
devices (a mouse, etc.) or a communication network. 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 JP6
