I think you have just repeated what I suggested but I do not accept that wiring a 1/2 duplex line like a spiders web will cause no issues.

Data buffer, not caused issues with it missing from g2

Nothing is foolproof to a sufficiently talented fool.

I doubt you will have an issue on a light loaded line without a termination resistor. There is one in the panel so most of the swr will be dealt with. Imo dont worry

Thanks everyone for your replies. I won't worry about it too much then. Sorry to have stired up such a debate!

Hi,

I installed a Galaxy G2+44 panel today and have just realised I forgot to install the 680Ω EOL resistor across the data line in the last Keyprox. I programmed it and everything was working fine when I left. Does anyone know how likely is it to cause me problem/callouts?

Thanks

Unless your data run is silly lengths then you should be fine.

It's all to do with reflections causing Probs on long runs and polling.

wont cause an issue, most that fit still forget to remove the jumper/cut resistor in panel when using two data lines.

 

Honeywell never ship them with keypads or RIOs which is a shame.

 

We do fit them but use standard alarm cable for anything under 100M now

i personally like to use Cat5e sheilded

Not good.

Technically, it works, but built in service faults.

how ? its twisted pair? its built for data lines 485 is a type of data so there is no issues

And it's brittle and snaps.
