NOTE
It is important to use only differential terminators
on a differential SCSI bus.
B.3.2 Interface Cable and Terminator Installation
To properly cable the drive:
1. Make sure that your host system has an appropriate SCSI interface card
and software drivers installed.
2. Inspect the terminator and make sure it is a differential type, to match
your system. SCSI terminators should be clearly marked “differential”.
3. Determine whether the module is to be connected in daisy-chain
fashion with other devices, or a single bus for each device.
4. If configuring each device for a single device per bus, the host
connection should be connected to the first connector for each device
and the terminator installed in the adjacent connector (refer to figure
B-5).
5. If configuring as a daisy-chain, the host cable connects to the first
Library connector, the second Library connector is then connected to
the DLT1 connector, and the terminator is connected to the adjacent
DLT1 connector. If configuring a second DLT drive remove the SCSI
terminator from the DLT1 connector and install supplied 1-foot SCSI
cable between DLT1 connector and the first DLT2 connector. Install
the SCSI terminator into the adjacent DLT2 connector. This
configuration is not recommended for the two tape drive DLT
MiniLibrary.
6. Make sure that the cable you use meets the specifications listed earlier
in this appendix.
7. Measure the cable length to connect the module to the computer
system.
8. Be sure that the length of the entire bus falls below the maximum
permissible length given in the section on SCSI cable specifications
