Fujitsu Scan Partner 300C Instruction Manual page 16

Configuration II: the number of devices attached to the SCSI bus (including the host PC) is three. The scanner is
located at the end of the connection, as shown below.
Host PC
Terminator
If there is already another device linked to the host via SCSI cable, remove the terminator from that device. If the
terminator can not be removed, it is recommended that the connection of Configuration I be used.
1. Set scanner's SCSI terminator switch on
2. Plug one end of the SCSI cable to one female connector of the previous device or the host.
SCSI specifications require that:
1. Only one terminator may be attached to each end of the daisy chain.
2. The total length of the daisy chain must not exceed 6 meters. The vendor suggests that the SCSI cable be two or
three meters in length to allow other devices to be attached to the SCSI bus.
3. Each device on the chain will be assigned a different ID. Devices with the same SCSI ID will cause them to
malfunction.
4. There is no restriction on the position of the devices on the daisy chain.
