    You might want to browse this thread. It talks about ICSNet termination.

    You can make your own terminators or buy the ones from AMX.

    But my problem it only happen when there is lightning strike or heavy rain.if it a dry weather the master will work perfact.i already installed a ups and lightning arrestor to master power.

    That doesn't eliminate the possibility of noise introduced on the line from static discharge. They should be terminated, no matter what; that could still be your issue. Those things are very sensitive.

    The DMS could be bad - corrosion on the board maybe? I've seen that quite a lot in harsh environments. Corrosion on the RJ-45's is possible too. How long is the wire run to the DMS? Any splices? It seems it almost has to be something in your system that is shorting out partially under high humidity conditions.

    Thanks,DHawthorne.
    At system 1,i got 2 dms hub with 4 dmskeypad each.Both of the hub at different part of the house.
    Plz give any idea what should i check or install?

    Aside from visually inspecting everything to make sure the connections are solid and there is no corrosion, I'm out of ideas :(. I don't think there is any other hardware that can help the issue. One of the problems troubleshooting DMS keypads is that one bad one can take out the rest installed on the same hub. It's hard to pinpoint which is causing the trouble unless it is obvious from looking at it.

    this is true! I did a job a while back that had 9 DMS keypads as well as 6 AMX ICSNet T-Stats. it was a nightmare getting all of them working on the three hubs involved.

    I did find that a few of the DMS keypads had mysteriously changed address (right on top of each other) That can really cause problems. I ended up doing a very exhaustive, one-at-a-time assessment of them. I'd basically plug one in, let it sit for a while, if all seemed well, add another. Wash, Rinse and repeat...

    it took a full two days to finally home in on the problem(s). One Keypad was just plain flaky and was replaced. The other was a Hub turned out to be bad and would wig out for no apparent reason. Once, we solved these two problems, the system has worked quite well.

    I, too, am afraid that it's not going to be easy or quick to figure out. We dont' have access to the ICSNet bus and it's communications. If we did, it might be easier to solve problems more quickly.

    Maybe one of those DMS analyser could help out to give you more information about the status of the bus.

    I'm sure that is what he meant. I've not found them to be very helpful myself.
