Connecting Several SCSI Devices
Because the CD-ROM drive is a SCSI device, it is possible to connect it to your
OmniBook in series with other SCSI devices—this is called a "daisy chain"
connection. Follow these guidelines for connecting your CD-ROM drive with other
SCSI devices:
The CD-ROM drive must be the last device in the daisy chain (the furthest from
the OmniBook).
The CD-ROM drive terminator DIP switch (switch 4) must be set to ON.
Each device in the daisy chain must have a unique SCSI ID number that is not
zero.
All SCSI cables must use shielded cable with the proper connector ends. The
cable should be shorter than 5 feet (1.5 meters).
The SCSI terminator and ID number DIP switches are located on the bottom of the
CD-ROM drive. Each switch is numbered: 1 through 3 are the ID number switches,
and 4 is the terminator switch.
The table below shows how to set the ID switches for different SCSI ID numbers.
