Connecting Cables
SCSI Connections
The last device on the SCSI bus must be terminated. If no external devices
are connected to the SCSI bus, the terminator supplied with the Model 745
must be installed on the external bus connector.
When connecting external devices, be aware that SCSI specifications state
that a single-ended SCSI bus must not exceed 6 meters. The bus cable length
internal to the Model 745 is 1.5 meters (including the .5m cable connecting
the board computer to the mass storage module). Ensure that all device
cabling connected to the external SCSI port of the Model 745 does not
exceed 4.5 meters.
Figure 2-8 shows the SCSI connector.
