Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi JMan, All,

@JMan,

Thanks for that, it looks readable (sort of) but boy it is a heap of code to digest.. I am currently exploring the possibility of using a Static IP address, (actually a range of static IP addresses to select from) or at worst case enter one in on power-up.

I have asked the question to see if there is an IP address that is un-allocated that I can permanently use, but as the system hasnt yet been installed that information probably is, at this stage, unobtainable.

I figure we can do a WSPING from the main control room end and find an IP that hasnt been allocated and adopt that at worst case.. So it is still a possible route to go with.

Kind Regards,

Mick Edited by bigmik 2017-04-18
