Interfacing probes to breakout boards

[DaveCVI]

Hi All,
Attached to this post is a short paper that describes an issue which can arise when interfacing a probe with an internal LED to a Break out Board that uses Opto isolated inputs.

The Wildhorse Econo-probe and tne Gecko G540 are used in the paper as an example (I wrote this up as a result of helping a MSM user with that combination).

This info will be included in a revision of the MSM user manual. In the mean time, I thought this might be of help to others.

Hi Dave,

Could you post the white paper?
Thanks

Sorry, that would help.... The file should now be available from the original post.

Thank you David.

I just installed a PMDX-126 (Rev A3) and have not hooked up the probe yet so that information is very helpfull and timely.

The PMDX126 makes things easy - it can combine two separate physical inputs into the mach probe input line - that takes care of the active hi/active low combination problem that results when you have both a probe and touch plates.

Hi Dave

I have currently this question to interface 2 econo probe on my system. One is used as a touch probe and the other is used as a Tool high setter and it is attached to the machine at tool change position. In the input table (associating parallel port pin to event) I have probe that is associated to my touch probe. How I can generate a probe event with my tool setter (second probe). I have one available pin on my breaker board I can use for that.

Thank you

Please see this thread before going down the path of using a moving tool setter.... "warning: there be dragons there..."
