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.

What works well for me is the PMDX-126 "breakout board". It has a feature where it can multiplex inputs. I have a in-expensive probe with the led, and a set of touch plates )one fixed and one mobile) on the same pp pin..

The PMDX has a OR feature. If either input is triggered then the probe input is triggered.

Yep, Steve at PMDX added that feature as a result of requests from MSM users... makes interfacing probes and touch plates easy.
