We have recently switched our web hosting so some of the links in Forum posts may be broken. I am working to make sure we get all of them reconnected so your patience is appreciated.
Current Software - Huntron Workstation 4.X / Huntron Workstation Remote Control
« Last post by admin on March 31, 2022, 03:20:18 PM »
The Remote Control feature in Workstation is one of those things that is somewhat difficult to explain. We took our best shot at explaining it in a recent video on our YouTube channel. The demonstration in the video surprisingly uses Excel to control Huntron Workstation running in the background by making function calls to the remote control DLL file.
Here is a link:

We have been adding a lot of new content to our YouTube channel recently.

Slowly but surely we are creating video versions of the "Quick Tips" posted on the Huntron Technical Support web page. (scroll down a bit and select the Quick Tips tab)

The latest video is a short 2 minutes on the popular Huntron Microprobes which we have been making since late 1976!
Huntron YouTube:

Another recent video discusses Huntron Workstation Remote Control. This has always been a difficult feature to explain to customers so hopefully the video helps clarify how it works.

Thank you fetron for the help, I will order today.

Thanks for the input, fetron. That part looks like a better solution than the original!

The original dc-dc converter pinout:
(1) +5V input, (2) -15V output, (3) output common, (4,5,6,7,8) blank, (9) not connected,
(10) output common, (11) +15V output, (12) input common

The new dc-dc converter:
A conversion board is required due to the terminal deviation.

I have checked all of the range resistors they are OK.
fetron pointed out a document that helped me isolate the problem to a (cdi 215D5FS) dc to dc convertor U49 that did not pass any voltage to the regulator.

Are there any current model dc convertors ? this part number is very old I may have to buy from overseas at a very high price.

Thanks fetron for the help

I believe the Relays here under the CRT can cause some strange problems on an old ProTrack as shown on attached photo.
An update on the fault would be interesting.

With help from Curtis I have used this method to test a number of circuit boards as I discussed on the Forum, but this time using Workstation to store the results.
Particularly useful useful for finding high resistance shorts between connector pins.
I found that the most reliable results against speed are obtained with a delay of 0.5 second using an Agilent 34410A +  workstation on my ProTrack + Scanner setup.
I work on agricultural circuit boards that are exposed to a damp,& dusty environment, and although only operating at 12 V.D.C. have lots of available current were a resistance of a few M Ohms, can rapidly fall to a few Ohms, and start heating up the area between connector pins.
As can be seen on my attached photo, and end up like the fire in second photo.
1 M Ohm  to 50 k Ohm short between pins can cause some strange CAN BUS faults for the Farmer.
If ever I get my hands on a 3200S, would be interesting to find the output from the relays and see if the same thing can be done. That is if it uses a similar internal setup?
If anyone wants details the adaptor used for this test just reply here.

Update to this test method developed by James--

It is possible to use Huntron Workstation to control the scanning with this setup.

The ProTrack is connected to the Scanner by the interface cable only and a Workstation supported DMM test line can be connected to the Scanner Channel A BNC connector. The COM connection on the DMM is connected directly to a common line that goes one side of all resistors on the fixture. The Channel A Scanner interface is connected to the fixture through a ribbon cable.
The test in Workstation is setup to use the Scanner as the Connection Type (set at the Component level).

The advantage here is that Workstation can be used to store and compare the measured DMM values captured through the ProTrack Scanner essentially using it as a switch matrix.

There is a tutorial on the Huntron website that discusses using a DMM with Huntron Workstation:
