GPIB: 24-pin Centronix connectors?

Not true. It is NOT a "cable select" cable.

Why should anyone believe this claim of yours?

If the volumes are high enough, the extra cost won't be much.

It probably pays for itself by allowing easy visual inspection and/or simplifying the text in the installation description.

Sorry... Had a "duh" moment. The problem I was speaking of is that the shell of the prologix device often interferes with the case of the instrument. I had thought that that was what you were having trouble with.

There is NO difference. 1M of any of the 3 connectors is the SAME PRIVE. Placing them into three different bins in your warehouse is the SAME PRICE. Using them during an assembly process is the SAME PRICE.

The idiot that thinks making the cable would cost more has no clue how manufacturing works, large or small volume.

It is a visual aid, and there have been others over time.

We all have our "duh" moments. I had mine yesterday at church. A friend and I mounted the motly collection of loose gear and cables into a nice rack, laid everything in cables channels, looks really professional. Turned it on for a test of all the sound channels. Big hum on all the Sennheiser wireless channels. Bit my tongue, after all you don't want an "unsuitable exclamation" slip out in a sanctuary. Turns out that all the cables from there to the mixer were non-diff. Great, just great ...

Hey Shit for brains, I never said any different.

this is where you are WRONG WRONG WRONG WRONG.

NO, never has, never will.

the drive has to be set in a compatible mode with any other drives on the cable, that is all.

Maybe they DO work, but PROPER TERMINATION requires the end device be a 'master', and the UDMA documents DO specify this. Noise margin is important, and "they work" is a very weak statement.

the

The cables support cable select function (or they aren't UDMA compliant); the choice of how to jumper the drive is not forced by this circumstance.

have you got a link for that? As far as I can determine AC termination is used at both drives

I've seen a few computer systems that actually reported that you had not used an 80 pin IDE/UDMA/ATAPI cable.

How does the mainboard tell 40 pin from 80 pin? Does it detect reflective noise or what?

On the other hand, I thought this was a thread about IEEE488/GPIB/HPIB and I didn't catch how it devolved into IDE/UDMA/ATAPI from there.

I vaguely recall that once there were minor but not to be ignored differences between those almost identical ""standards"".

Apparently lab instruments is the last niche for '488?

I was scratching my head about the "garden hoses" comment but it congealed when some comments came up about multiple piggy backs and I recalled how ugly four or five '488's piggybacked really were!

In modern medlab or electronics labs, have USB 2.0 or Firewire become the new standard?

You are full of shit.

You are a goddamned retard. Always has... always will.

Wrong. When using 'cable select' feature, BOTH drives get set to cable select, AND a MODIFIED 'cable select' cable MUST ALSO be used. In such cables, the RIBBON gets holes punched in it and THAT is what detaches certain pins on the assembly where the SAME CONNECTORS are used throughout the ENTIRE INDUSTRY.

If you were any more clueless, you'd be named Roy!

Dumbfuck! In an IDE channel there is ALWAYS a master, you stupid f*ck. The drive is where the controller is!

You're a goddamned idiot. In ALL IDE channels, one drive is the channel's master, and the other drive, if and when present, is SLAVEd to the first drive.

You're a goddamned clueless f*ck, and you are not even qualified to be having this debate, punk.

You're an idiot, and you're stupid as well, so you likely bought some lame brand of drive that is a master, regardless of what the stupid consumer brained installer (you) sets it to.

Standard IDE did not matter. UDMA is twice the data rate, and it DOES MATTER, and the reason is because of reflections.

I'd call it "old". Anything designed now would use USB.

Yes.

All PCs come with USB ports. Hubs and cables are readily available at low cost.

GPIB/488 adapter cards are expensive.

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.
