AGFA Horizon Ultra Scanner Owner's Manual page 27

If your Horizon Ultra scanner is the only SCSI device to be connected
to your Apple Macintosh:
1. Connect the smaller 25-pin end of the System 25-pin to 50-pin
cable to the SCSI port on your Apple Macintosh.
2. Connect the 50-pin connector to the scanner.
3. Place the terminator on the scanner's remaining 50-pin
connector.
4. Snap the diamond shaped wire clips into the clip brackets to
secure the connection.
If your Horizon Ultra scanner will be connected to your Apple
Macintosh together with other SCSI devices:
1. Connect one end of the SCSI cable (supplied with the scanner)
to the adjacent SCSI device.
If you install the scanner at the end of your SCSI chain, remove
the terminator from the last device in the SCSI chain. Connect the
cable to the SCSI port that has become available on this device.
If you install the scanner between two other devices, disconnect a
SCSI cable from one of these two devices, and connect the free
end to the scanner. Connect the SCSI cable between the scanner
and the remaining open port.
2. If the scanner is the last device in the SCSI chain place the
terminator (supplied with the scanner) on the unconnected SCSI
port of the scanner.
Remember your Horizon Ultra scanner has no built-in terminator.
3. Snap the diamond shaped wire clips into the clip brackets to
secure the connection.
Warning: Make sure there are no more than two terminators in your SCSI
chain. Some SCSI devices have built-in terminators and must therefore be
placed at the end of your SCSI chain. Please check the documentation of
each of your SCSI devices if you are not sure whether the device has a
built-in terminator.
Apple Computer, Inc. recommends using its proprietary black
terminator for the Apple Macintosh IIfx.
