Toshiba XM-6401B Instruction Manual page 15

Daisy-Chaining - If the CD-ROM you are installing is one of two or
more SCSI devices you have connected to your system, you will need
to use a custom built SCSI interface cable. Remember that the termi-
nator jumper on the CD-ROM drive must have the jumper installed
when the drive is the last device in the chain.

TXM6401F1/XM-6401B DAISY-CHAIN CONNECTION (MULTIPLE DRIVES)
Notes:
1. Terminator jumper must be jumpered when CD-ROM is the last or only device on the SCSI BUS.
2. Terminator jumper should be removed when CD is in a "daisy-chain" and is NOT the last drive.
3. The TXM6401F1 uses an external terminator which must be attached to the last drive of a "daisy
chain". The external terminator is an optional item.
