I am a retired alarm installer and have just been working on my Gardtec 816,
I have an old windows XP PC which I keep for programming this and some other old stuff.
Today I successfully connect to the alarm panel after a while it lost communications and I seem unable to get it to work.
I have tried all the obvious stuff: restart PC, check the leads, ensure alarm panel setting are correct to allow connection.
I am hoping somebody will have some experience with this and can suggest some ideas to help.
Thanks Colin
