CDR-3100 (250-1098)        Adapter/Cable Install       Faxback Doc. # 2598

The following steps describe how to connect the data and power cables
between the CD-ROM drive and the adapter interface card.

1. Plug one end of the supplied ribbon cable into the CD-ROM's 16-pin
   connector. Be sure the index notch on the drive's connector matches the
   cable's connector. (cable should be labeled "drive end")

2. Plug the other end of the ribbon cable into the adapter interface
   card's connector labeled P2. The cable is "keyed" -- do not force the
   connection.

CAUTION: The owner's manual for the CDR-3100 does not adequately explain
         how the data cable is connected between the drive and interface
         board.  The cable connects in only one direction. However, if
         forced the cable can be connected backwards. The data cable has
         two header connectors, one end is "keyed" by blocking one of the
         pin locations; this end should be connected to the P2 connector
         on the interface board. The other end is not keyed, but does have
         a label that states "drive end" which should be plugged into the
         CD-Rom drive.

If the cable is plugged in backwards. They may experience these type of
problems:

    The drive does not work at all.
    The error "fail int 24" when a directory is taken of the CD disk.

Note: An audio CD may play just fine, but the data CD will produce the
      "fail int 24" error when accessed.

Your CDR-3100 has a stereo headphone jack and volume control on its front
panel. These let you use stereo headphones to listen to compact discs
(CDs).

Faxback Document # 2400 will provide instructions on playing audio CDs.

The adapter interface card has audio output jacks that let you connect the
CD-ROM's audio output to an external amplifier and speakers. Using cables
with RCA plugs on the ends, connect the adapter interface card's audio
output jacks (the top jack is the right channel and the bottom jack is the
left channel) to your amplifier's LINE IN jacks.

Note: The CD-ROM drive's VOLUME control does not affect the signal from
      the adapter interface card output connectors.
