Connecting Wide SCSI-3 Devices (68 Pins)
It is possible to connect a wide SCSI-3 device (68 pins) to the K1297
Protocol Tester using the delivered SCSI adapter.
The SCSI interface of your Protocol Tester is wired like a SCSI-1
interface. To connect a wide SCSI-3 device (68 pins) you need this
specially qualified 50-to-68 pins SCSI adapter.
CAUTION.
Some commercially-made adapters may cause a short circuit
between TERMPWR and GROUND if they connect pins 12, 13 and 37 of
the 50 pins SCSI interface to pins 17, 18 and 51 of the wide 68 pins SCSI
interface. Such an internal wiring will cause the failure of the SCSI
connection.
Use only the SCSI adapter delivered with your Protocol Tester.
The following table shows the crucial pin connections of the qualified
Tektronix 50-to-68 pin SCSI adapter:
