Re: Information on 37203A HP-IB Extenders
Mark KAHRS
Well, looking at this here manual, there is a RUN/TEST switch (A1S1).
The test switch is A1S2 ( 6 pin DIP sw) . You need to set the COAX/OPT switch (A1s5) TO coax... finally, you have to set the rate. The test switches A1S2 should be in the OFF position BTW. What else? |

Information on 37203A HP-IB Extenders
I've recently tried to use a pair of old 37203A HP-IB Extenders to extend the distance of several IEEE-488 instruments from the controller.? I don't have a manual on hand, but I thought the units should be fairly straightforward to use.? I set the "controller end" as Master and the "instrument end" of the link as "Slave," the rates at the same setting (Normal), and connected the power and -488 instruments.? Although I can see a series of negative-going pulses on the coaxial interconnecting cable, I can't seem to get communications between the controller and the instruments.? The length of the cable is about 150 meters. Can anyone give me any guidance for their operation?? There are a few "mystery switches" inside the units along with a jumper printed wiring board -- I left all these as they were.? Any help would be sincerely appreciated. Regards -- Tom Leedy |
Re: Digest Number 50
Ian,
In the HP 8558B service manual, it looks like those switches are just assemblies of many different HP part numbers. I could be wrong. I've never looked at an 8558B. But I didn't notice a part number for an entire rotary switch assembly, except "Front Switch Assembly (Mechanical Parts)", HP part number 08558-60100, which includes all of the mechanical parts for the entire front panel switch(es) assembly. Your BEST bet is probably to find an 8558B "parts unit" to get the parts from. You can probably find one on , eventually. Note that you can put an "auto-search" on eBay, so you'd be automatically emailed whenever anything matching your search came up for auction. Just go to "My Ebay", then "Favorites". Darn! I just searched ebay, for "8558B", and then clicked on "Show Completed items", and it looks like an 8558B Front Panel Switch Assembly sold on Dec 15th, for $57.55. Maybe you could contact the buyer and see if you can get some parts from it, or maybe just get all the rest of it after he gets what he needs. You can go to and then click on the winning bidder's ID (kcands). You could also contact the seller, similarly, to see if they might have more of them, or the parts you need. (They are a test equipment dealer in Wyoming.) Also, you could try asking Walter, at Sphere Research, at: But, if you do need any HP part numbers for individual switch parts, such as rotor/contact assemblies, shafts, or whatever, I can look them up for you. You would need to be very specific about the locations of the parts, since the rotary switches' parts are not all interchangable. I also have the full service manual available (362 pages in two manuals), on CD, at: Good luck!

Re: HP 4952A software copy protection?
From what I have heard (so cant confirm) is that when the progs are
copied from the orig disks there is a bit set on the orig and the copy of the program that allows only one copy. If the orig disks are copied with a program (on a PC) that will make a "image" of the disks you should be okay. Regards Steve Hi AllThese have been copied using the LIFUTIL utility. However wheras the datagive an error "Application Denied". I suspect and have read somthingabout this being some HP copy protection. |

I'll gladly contribute some dead A/D boards to the reverse engineering cause. This board is probably the single largest failure card in the 54111D family. People will buy up 54111D carcasses just to rob the A/D boards. On occasion I have seen working A/D boards sold (off Ebay) for as much as $1500 each, when you can find them at all. I own of the beasts, one working, one about to be working, and one parts carcass (which I robbed the A/D boards out off 8^) If the schematics and board overlays still exist somewhere inside the organizational train wreck that has swept through HP over the last few years then the only way they will ever see the light of day is through a clandestine smuggling job from the inside. Agilent/HP wont even release the copyrights to the manuals for equipment that has been obsolete for 40 years let alone the schematics for a 10 year old piece of gear I wish you luck with your dream.

So, my advice isn't as applicable. Looking at the pictures in the two auctions below, the probe tips aren't just simple wires. Note the wires all go into a plastic block, which then attaches to the HP 10271A and HP 10272A boxes. You need these wires ends, right? They probably have some kind of RC network in them, like the pods described in the PDF file above. You might try contacting vendors that rent or sell used equipment. These units are old enough that they may have a set laying around which they are willing to sell for cheap. Good luck. Sorry I wasn't much help. Mike -- ---------------- Michael Lohmeyer mike@... |

Hello Mike,
To understand better how your 1631D cables are wired and howyou can use them, look for the PDF file manual on Agilent's web sitesells. The manual is continually updated for the current equipment, butmost of it is still applicable to the older logic analyzers. It showsthe pinout and electrical characteristics of the cable ends (withoutyou get desperate, let me know and I can probably dig up the manual forDo you mean this pdf?

Every now and then, someone puts up a set of grabbers (just grabbers without the pods) and they tend to go for about $20 per set of 20 grabbers. Of (just in case I misunderstand), if you need the pods as well, they also come up on ebay a lot (more often than just the grabbers). My definition of pods is the part that attaches to the end of the long ribbon cable, and has the loose wires coming out the end (GND, clock, and 16 data leads). The grabbers would then attach to the loose wires. Complete pod sets (pods, grabbers, ground leads, etc.) seem to go for about $30-$40 per pod, or $120-$160 a set of 4, on ebay. I just picked up a brand new set of 4, never opened for the low end of that price.

I thought the Pods have MTAYou can also buy grabbers from any of a number of different places that sell wires and things (like banana plugs, lab interconnect wire, meter and scope test leads, etc.). They won't be exactly the same as the original HP grabbers, but they may be acceptable for your needs, or you might even find better grabbers (though, probably for a much higher price). Anyway you look at it, though, grabbers are expensive. I just finished buying pods and grabbers for my logic analyzer. I had to buy 12 pod sets. Ugh! Luckily, I got better than average deals for them on ebay, but it still adds up quickly. Mike -- ---------------- Michael Lohmeyer mike@... |
HP 4952A software copy protection?
Richard
Hi All
I have obtained some software for the 4952A protocol Analyser. These have been copied using the LIFUTIL utility. However wheras the data files work fine the applications (things like a VT100 emulator) give an error "Application Denied". I suspect and have read somthing about this being some HP copy protection. Can anyone help or make any suggestions? Many Thanks Richard |
