Ok, fixed the Windoze problem by moving a dll into path and looking at the full dump for the Linux run we have a similar but not the same error:  It's wanting a library called "jspLux86" instead of "jspWin" so I figure I've got another problem as that name is not present in the install files.

Below is a dump of the error message.  There is a real COM1 on this laptop and it works with all the miriad of other PLC packages I use.  The editor, TL53.jar is working fine.  A side note:  The reason why I have not reported this earlier is because this is the first time I personally tried to program our T100MD+.  The usual laptop is not here for me to compare with at the moment.

Mark:  You misunderstand me, I didn't post the whole thing again because I no longer have it.  I typed it online and it got erased when I clicked "Post".

Wow!  That's one high-pressure looking sales job.  Anyone that fits that description is a walking corporate dream.

I've recently been experimenting with setting up the office with a Linux based PC and just installed SetupTL5.exe under the MEPIS distro using CrossOver.  After chasing missing icons I found that there were plain .jar files that could be run straight from Linux.  I did so, using the command from TL5.bat, and the editor popped up just fine.  

Sadly, apon trying to load an example PLC program it would fail saying it couldn't find the file.    However, I can make a new program and save and reload it in the examples directory so there must be a file format problem (eg: CR/LF vs LF only).

Also, it's getting tons of font errors listed via stdout/stderr which, not surprisingly, causes much lose of info in the rendering of the editor.

I suspect there is not much stopping this.

I tried running the server using "java -DSERIAL_PORT_LIST=/dev/ttyS0  -jar TLServer21.jar" but it was less succesfull complaining that:

Anyone in the development team been experimenting?

Looks like you are in luck, I found that there is cheaply priced chips that perform isolation via capacitors instead of the more expensive transformer method and whats more they do it completely internal to the chip so you only need deal to power supply and scaling.  

http://focus.ti.com/docs/prod/folders/print/iso124.html

You should be able to wire it up using the battery sense wires as the input supply.  This will be quite accurate due to your circuit drawing a constant current and there not being any possible earth loop.  The only concern there is whether it's happy to operate from a single supply rail.


Cheers,

Full isolation is indeed the most reliable way to go but is way more expensive and also has many more parts that can fail including another power supply.

Instead, you can use differential sensing and rely on full earthing to give a resonable common-mode reference.  With this method you still use twisted-pair for sense wires but need just one op-amp to convert to single-ended and it can do the scaling at the same time.  Best to use an "instrumentation" op-amp, it doesn't cost much more and combines three op-amps into a particular config for better common-mode rejection.  Also, sometimes these only require a single resistor for gain setting.  

The limitation of this method is the noise and particularly the signal levels must stay between the power rails.  If it floats away then you will get wrong readings.
