Welllllllll.... I bought one of these gadgets to do some debuging. I
just wanted the lights which show the control lines on the scsi buss
Anyway to quote from their manual
" SCSI Rx allows maximum daisychain distances of up to 80feet....
designed to meet ANSI fast and wide performance stnadards
I bought this at a local electronics computer store. Tech contact for
the manufacturer (per the manual).
Model number FPT-1000 Force Perfect Terminator
(there are several others for various kinds of scsi buses)
Mail: Interex Computer Products

Phone 316 524-4747 ext 232 Mon-Fri 8-5 CST
fax 316 524-4636
The name of the company is really Data Share, Inc. dba Interex...
I have seen mention of force perfect termination in one or more scsi
spec documents on the net. That is what gave me the idea to buy this
thing when I was having some termination problems (turned out to be a
bad cable).
Good Luck
Michael
