Hello Ken

Thank you for replying to my questions.

One of the reasons for purchasing the Nee controller back then was it's ability to produce the G-codes from a drawing, thereby I would not need to learn G-coding or machine codes. However little did I know that I would find myself in the position I find myself today with no access to the controller to export code into it.

I'm hoping you might be able to help me, right now I cannot decide if the dongle has broken down or there is a software counter inside the dongle, i.e. a time clock or a counter on how many times it has be fitted to different computer parallel ports Or the output from these three computers parallel ports is giving out the wrong voltage or speed signals.
Having read your comments on the 486 I am now cobbling together a very old computer to see if that does the trick, but I am not holding my breath.

I'm being forced to have a look at other controllers i.e. the Mach3 but having read the Mach3 installation manual on page 34 it shows the pin out on the parallel port and it also states there could be a problem with parallel ports for the very same reason. I have no idea how the hi or the low voltage on each pin is set or where you set it from, this sort of stuff is beyond me.
Do you have any ideas on how, a parallel port outputs can be tested, it would be interesting to find out what the three computers are sending out to the parallel port.

In the Bios there are a number of different option on the parallel ports, what is your Nee computer set at? On the Nee GPS installation software Cd there is a statement from Rainbow, who have a SET SSI_ACT. exe file in there, I am assuming that ties up with the Bios setting.
I have downloaded and got going both lots of dongle finding software from Sentinel/Rainbow but even that could not find the dongle i.e. dongle not found.

By the way I have traced down the family tree of the Nee controller, and who eventually purchased it, the final owners is ITT who closed everything down 10 years ago, so we are both trying to keep obsolete equipment going, just like my car.
Right now I am spending hours trying to get this problem solved but until it is one way or another I cannot move forward but it does not look good.

Please keep in touch
kind regards
