(Models SIR-xx)
Now when your SCSI bus is just a bit too short, there is a simple, economical solution: Paralan's SCSI Isolating RegeneratoR. A Paralan RegeneratoR sends and receives SCSI transmissions at maximum sustained SCSI data rate - up to 40 Mbytes/sec Ultra SCSI.
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!
To obtain one extra SCSI length, simply select the RegeneratoR model appropriate for your system, and plug in your cables. Daisy chaining of three or more RegeneratoRs is also possible, depending on model.
Wide SCSI (16-bit) may be placed on one side and narrow SCSI (8-bit) on the other side. SCSI communication will be accommodated and all lines will be properly terminated.
Devices on one side of the RegeneratoR may be disconnected and not affect devices on the other side, as the signals on each side are isolated.
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.
Paralan RegeneratoRs are completely compatible with all devices that conform to the full ANSI X3T9.2 standard. They are available either as stand-alone units utilizing wall power, or as board-level units for installation in other equipment.
RegeneratoR models are available for both single-ended or differential systems; fast and wide (16-bit) or fast and narrow (8-bit).
For differential SCSI applications specify the differential versions of the SCSI RegeneratoR (Models SIR-xx). Paralan also has Converters (Paralan SDxx series) for converting between differential and single-ended SCSI devices.
Paralan is the world's leader in SCSI extension. If your needs require longer lengths than those managed by Isolating RegeneratoRs, Paralan offers SCSI Fiber Optic Extenders that extend the SCSI bus up to 1000 feet. Or if your needs only require extension to 300 feet we offer SCSI coaxial extension.
Paralan has single/differential converters that can also be used as extenders. Please contact us for literature.
