Step 2.
Locate pin-1 of the 50-pin
SCSI connector on the Ultra Narrow
SCSI HardTape Bay PCB. (See
Figure 2).
Step 3.
Identify pin-1 of the SCSI ribbon cable connector. This will be
the same side as the colored line on the ribbon cable itself (See Figure 2).
Step 4.
Connect the SCSI ribbon cable connector to the Bay PCB
connector aligning pin-1 to pin-1.
Step 5.
Connect the 4-pin power cable to the Bay PCB.
Configuring jumper settings on your Ultra Narrow SCSI HardTape Bay.
There are three functions to set via jumper selection on the SCSI
HardTape Bay JP2 connector (See Figure 3):
•
Terminator enable/disable
•
Terminator power on/off
•
SCSI ID number setup
Figure 3
Figure 2
Please follow the instructions below to determine your jumper setting.
Step 1. Terminator Enable / Disable (pins 9-10)
When your device is at the end of the SCSI bus cable or there is only one
device on this cable, the terminator should be enabled. If you need to
disable the terminator, remove the factory installed jumper from pins 9
and 10 (see Figure 4).
Pins
1, 3, 5 : SCSI ID Number
2, 4, 6 : SCSI ID Common Ground
7,8 : Not Used
9, 10 : Terminator Enable/Disable
11, 12 : Terminator Power On/Off
Figure 4
Step 3. Terminator Power (Pins 11-12)
Default setting is on. However, you can turn it off by removing the
jumper between pins 11 and 12.
Figure 5
Step 2. SCSI ID Number (Pins 1-8)
For every device on one SCSI adapter card, there is a unique ID number
identifying that device. Use the information in Figure 5 to set a unique ID
number for your SCSI bay.
