More than a diagram, its actually in the docs.

It is a bit difficult to do that in the PlasmaC docs as there are several different ways of doing it, for instance there is the way Rod linked to plus there is the another method described in the primer using the ohmic component plus there is a method that uses a separate probe that is extended etc, etc. So all PlasmaC provides is an output and an input that hopefully will allow all these different methods to work.

Ah that's where it was hiding. I searched the manual and did not find it It would be nice to put a link in the main manual to the primer .

I had read the Primer when PlasmC first started but forgot it had that in it.

On the fourth line:

I don't think there is any place for instructions about hardware and circuit diagrams in the plasmac software manual. It really should be in the primer.

Sorry Rod but I can't agree with that The Primer is an introduction and not a manual and there are examples of all sorts in the manual including RS-485 connections and and ArkOK suggestions. A link around section 29 would help others looking for it.

I know that you and Phil are very active and probably can recite the manual backwards. But once you have read the primer then you progress to the manual and that for most people is the bible .

Or perhaps, there could be just one document starting with the primer then following on to the manual

Don't wish that on us!

Just wondering what could be wrong in having the two docs amalgamated into one. The first being a preface

I See that there are two totally different topics. One is a background document about the plasma process with design tips to help you build your machine and how things work.

The other is a software manual. They need to be kept seperate as you don't need the background once you have built your machine. You just need to know how to use the software.

If you follow that thinking all of the RS485 setup stuff in the plasmac doc should migrate to the Primer.

I'm not saying that because I put the primer together but I am big on compartmentalising stuff. We should not be mixing hardware build with software... I don't mind if others edit the primer document if they follow those rules.

I agree

Agreed but you also need to know how to install it. The PlasmaC manual was designed as an IOM.

I disagree here, the RS485 referred to in the PlasmaC is to connect to PlasmaC, it seems odd to look in a generic background document to connect it then a IOM to use it. It belongs in the IOM
