SCSI Internal Cable

The SCSI VUE Teflon Flat Ribbon
Cables are the best internal cables available
on the market. With both dielectric and
crosstalk properties that are far superior to
PVC. With the perfect impedance (90 ohms).
Teflon is the best material for Fast and
Ultra SCSI Bus.


it provides exactly
what the SCSI bus
needs and improves
performance


Using a patented 3 prong Gold Connector System,
the SCSI Vue Teflon Flat Ribbon is the most
reliable internal cable available for for SCSI.
The connector actually makes contact with each
wire in four Locations, offering twice the security
of standard connectors.

 Granite Digital offers the unique service of custom cables in one day. If you do not find the cable you need in the above list, you can have a special cable made.

Two common custom cables are shown below. We have added a connector to the far right end of each cable so that our High Precision Active Terminator can be attached to the end of the cable.

The advantages of doing this is that you now no longer have to worry about terminating the drives. If you add or subtract drives it becomes a simple matter of setting the SCSI ID and making sure the terminator is removed or turned off. The other advantage is that our Active Terminator is a matched fit for our 90 Ohm Impedance cables. Using them guarantees the best possible data transfers and the highest reliability. Also note that our 68 pin cable can have 50 pin adapters attached. See picture to the left.

50 Pin Cable Construction Hints:
Start measuring from the SCSI Host Adapter. Connectors are facing you, watch for orientation, notches right or left.
(note that most drive notches face upwards but some don’t. If possible leave 12″ between drives so that you can reverse the connector if necessary) If you want the connectors to be attached in both directions (top and bottom)
you must also draw a side sketch showing their orientation. Make things slightly longer. (nothing worse than a cable that is a little short)

Additional Considerations: for 68 Pin Cables:
Try to keep all lengths as similar as possible, and do not go shorter than
6″. There is a property called Reflection and it can cause a problem if the
drives are too close together. 12″ is the optimum length between drives.
