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.

Bigmik,

REALLY PERFECT would be this Device, with an Openwrt Linux Image on it.
With WIFI, Rj45, RS232 and the complete World of Linux ( shell etc.) is open
for you.

No limits to the limits of your Imagination;-)

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
