EXTEND HVD SCSI COMMUNICATION LENGTH WITH A Paralan RegeneratoR™

The maximum SCSI cable lengths are limited to 25 m (82 ft.) for HVD SCSI and 6 m (20 ft.) or less for SE SCSI. Often SCSI communications may be needed over greater distances.

This distance may be increased using a Paralan RegeneratoR™, which also isolates the two SCSI bus segments connected to it allowing hot-swapping of SCSI devices.

• Get double, triple, or even greater bus length
• Put Narrow and Wide devices on the same bus
• Isolation - Change or remove devices from the SCSI bus without affecting other devices

No need to modify software or hardware! Just connect your SCSI cables to a RegeneratoR™ and all devices on the bus will be available at an extra bus length. It's as easy as that!

An example showing daisy chaining is shown below. For a full discussion on SCSI Extension see the Extending SCSI page, and the article The Case for SCSI Expanders.

THE REGENERATOR™ IS NOT JUST A REPEATER!

Cable causes timing delays of approximately 1.5 ns per foot of length. When SCSI-specified cable length is exceeded, this cable-caused delay would normally cause a system to malfunction. Logic circuitry in the RegeneratoR™ manages this delay such that disconnect, reconnect, arbitration and all other SCSI features are not affected. The SCSI signals are regenerated, reshaped, and retransmitted, all transparent to the system.
