Installing IDE, Floppy & SCSI Devices 8-15
2 - Connect SCSI Cable (Power Off)
Make certain that both ends of the SCSI cable are terminated and that all devices in
between the ends are non-terminated. The SCSI connector on the TEK-AT4LVG board is
terminated.
The following list includes approved vendors for the J2 connector’s mating parts:
Robinson Nugent IDS-C50PK-TG,
Amp 1-746285-0 [optional strain relief: 499252-4],
Thomas & Betts 622-5030 [optional strain relief: 622-55041].
(50-pin flat cable connector).
Attach one end of the SCSI cable to the J2 SCSI 50-pin connector. Make sure line 1 of the
cable is matched with pin 1 of connector J2.
Attach the other end to your SCSI device, making sure line 1 is matched with pin 1 on
your device.
You must also install a cable from your power supply to your device.
3 - Follow Specific Device Installation Instructions (Power On)
Follow installation instructions provided with your SCSI peripheral device to install it in
the host.

Each device being installed must be assigned a unique identifier called a SCSI
Target ID. The lower the ID, the lower the priority level of the device in the
SCSI sub-system. The host adapter is usually assigned the highest priority
level (i.e. 7). Table 8-3 lists common SCSI Target IDs.
