Infrared Interference?

    I am using infrared detectors to throw the switches into one staging loop. If a train interrupts the IR beam they throw the switch so they will not run against a closed switch (bad in a hidden yard).

    Since I have started using my Digitrax Infrared Throttles the detectors stoped working. :angry: When I fire up the DT400R the detectors goes dead, when it goes into power save the are back "life" again.

    I am using radio for wireless ops, so I am not even keen on the IR feature.

    The detectors are in a hidden yard, but I am using a light-grey tiled floor, so there si always the chance of IR "bouncing".

    Does anybody have experience with this kind of "whiteout"?

    Any advice is appreciated...
    Cheers

    If you are using the radio feature of the DT400R, I believe you can set it to where the infrared transmitters are disabled. I have a DT300 and you can set it for infrared & radio, infrared only, or radio only.

    Yea, what he said ! :teeth:

    Another thing to consider would be adding some sort of shielding to your IR detectors (like a short section of tubing) to reduce exposure from off-axis "noise".

    Thanks Guys.

    I have changed the setting to "Radio Only", but still the same. Some more testing: The IR detectors go dead when I switch on the track power....???

    So I assume that I have an overspill of the track power bus into the 12V DC bus somewhere, so the meter reading at the detector do not change when I switch the DCC power on or off.
    Next step: I am going to discsonect the detectors and wire them to a stand-alome power source. Let's see what happens.

    Cheers

    Different power to detectors

    Caddy58,

    What you're doing would be my next suggestion...power the detectors from a different source and see what happens!
