It's been really long ago that I had to make custom GPIB/HPIB bus connections. Are those the regular 24-pin Centronics like this one?Reason is that the Prologix adapter bangs into the wall behind the equipment rack. And I don't want any of those garden hose cables, never no more :-)-- Regards, Joerg"gmail" domain blocked because of excessive spam.Use another domain or send PM.

Yes. I have a whole tray of 60 surplus AMP 552740-1 24 pin PCmount on hand.-- Goggle Groups, and Web TV users must request to be whitelisted, or I will not see your messages.If you have broadband, your ISP may have a NNTP news server included inyour account: There are two kinds of people on this earth:The crazy, and the insane.The first sign of insanity is denying that you're crazy.

GPIB: 24-pin Centronix connectors?

Oops; I overstated. The end device should be PRESENT if the termination is to be correct, but the UDMA document I was thinking of (ATA-ATAPI 5 rev. 3) only requires the master at the end in section 5.2.13.2 saying "For ... all 80-conductor cable assemblies... device 0 shall be at the opposite end of the cable from the host" and this relates not to the termination condition but to the cable-select feature.

The termination of master and slave (device 0 and device 1) is not different in the electrical sense.

the plugs are not straight-through plugs. most of the pins are but each colour of plug has a few of the pins tricked (eg:open or gounded) in a different way.

Thanks!

my appologies to all for attempting intelligent discussion with Archimede's Lever who (like his hypothetical namesake) is apparently thicker than two short planks.

Complete crap. I have made 40 conductor IDE cables with straight cables and standard ide connectors.

Picky picky picky. Worse, you have been around here long enough to know better.

no, it's true.

yeah 40 conductor cables are wired straight-through (optionally with the cable-select pin extracted or conductor cut on one of the plugs.)

and the 80 conductor cables used in PCs have tricked up plugs so that some pins they aren't wired straight-through, and because of this they can be detected by measuring logic level on the pins.

No cut wires, twists or any other crap, just 40 pins straight through.

Lost interest in the cables long enough ago that i have not DPA 'd an

80 pin cable. Maybe i will do that some day, just to find out for sure.
