[time-nuts] Tektronix TM500 extender cable kit
I got in my prototype extender cable boards from OSHPARK.COM today. OSHPARK only builds boards in multiples of 3 and I only ordered three boards so could only build one cable. It seems to work very well. I tested it with several different TM500 and TM5000 modules (using another set of cables I have with the dual and triple wide modules) and they all worked fine... including some real power hogs like a Ball Aerospace rubidium oscillator. I have a bunch of circuit boards of a different design on the way from a new (for me) Chinese vendor. If they look good I'll order a couple hundred of the extender boards (it takes two boards to make one cable). I have also pimped out the original extender board silkscreen and added an LED to the +11.5V supply. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] Tektronix TM500 extender cable kit
I knew about the GPIB but since I don't use it 99% of the time its not a challenge especially since the only reason I extend a module is to fix it. I did not know that there were 3 bay modules. Learn something every day. But don't own one. Regards Paul WB8TSL On Tue, Aug 5, 2014 at 5:37 AM, David C.

Hi Mark, After all the effort you just put in, you'll be a touch annoyed that Jamma Boards have done a kit for TM500 extenders for ages ...

Re: [time-nuts] Tektronix TM500 extender cable kit
Mark; Could you describe your design a bit more? E.g., 1) There are connectors at both ends of those cables; what are your socket provisions for the module end? 2) Do you use 0.1 40-pin headers at both ends, or some other form of termination? BTW, I'd be interested in some, as well, depending on design. JimT Sent from *my* galaxy (Nexus).

Re: [time-nuts] Tektronix TM500 extender cable kit
Several people on the TekScopes/Tekscopes2 forums went through this a while back. It turned out that ribbon cable appropriate for this application was either not available or too expensive. John Griessen made a set of PWBs and sold kits consisting of a PWB pair, a connector pair and a set of pre-cut and pre-stripped wires. I believe he sold all the kits. I built one of mine and it works well. I use it with a TM-501 as a stand-alone test setup for single-wide plug-ins.

Re: [time-nuts] Tektronix TM500 extender cable kit
It turned out that ribbon cable appropriate for this application was either not available or too expensive. Are standard disk cables a reasonable length? (and a pinout you can use) I don't know the details, but there are two types of disk cables. The old style uses standard 40 pin ribbon cable with not-great grounding. The new/fancy style uses 80 pin cables but the same old connectors. I assume the extra wires are grounds with some magic in the connector to connect them all to the IDE ground pins. (so they won't work for arbitrary pin assignments) There is also twisted-pair ribbon cable. There are untwisted/flat sections every foot or so where you can install standard connectors. I'd expect it to work well if used with differential pairs. Digikey carries it. -- These are my opinions.

[time-nuts] Tektronix TM500 extender cable kit
Yes, all 56 pins are extended, including the PWR pin unique to the 5000 series (it is a power good/power-on reset sort of signal).Several of the TM500 modules are also double-wides and need two extender cables. I have not done an extender for the GPIB connector, but that would be easy to build. When I've needed to extend the GPIB bus in the past, I just used a cable that had a 20 pin ribbon cable edge card connector on it and a standard IDC header on the other end that plugged into the mainframe motherboard where the GPIB connectors connected (the mainfame I was using had the GPIB connector bus built out of IDC ribbon cable/connectors. - Am I right in thinking that two of these connector/cables would give the full facilities on the 5000 series units. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
Re: [time-nuts] Tektronix TM500 extender cable kit
You are right thats why I am thinking about 2. On the ribbon cable discussion I do agree ribbon cable can be fragile unless solidly tied down then they are pretty stable. An approach I have used in building extenders for RS sig gens that use Euro boards is the same stranded wire type for all pins. Granted all the same color but you can get pre-cut lengths and the wires much heavier gauge as you would want in an extender.

Well, just for grins, I did a small board for extending the TM5000 GPIB connector.
