8.1.3 Setting the TZ88N-TA SCSI ID
The TZ88N-TASCSI IDis set with a push-button counter switch on the rear
of the unit. Push the button above the counter to increment the address;
push the button below the counter to decrement the address until you have
the desired SCSI ID selected.
8.1.4 Cabling the TZ88N-TA
Youmust connect the TZ88N-TA tabletop model to a single-ended segment
of the shared SCSI bus. It is connected to a differential portion of the
shared SCSI bus with a DWZZA-AA or DWZZB-AA. Figure 8–6 shows a
configuration of a TZ885 for use on a shared SCSI bus. You can replace the
TZ885 shown in the illustration with a TZ88N-TA. Toconfigure the shared
SCSI bus for use with a TZ88N-TA, follow these steps:
1. Youwill need one DWZZA-AA or DWZZB-AA for each TZ88N-TA.
