8.1.3 Setting the TZ88N-TA SCSI ID

The TZ88N-TA SCSI ID is 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

You must 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. To configure the shared SCSI bus for use with a TZ88N-TA, follow these steps:

1.You will need one DWZZA-AA or DWZZB-AA for each TZ88N-TA.
