When trying to run or running a train using the DCS handheld I lose control of the speed through the handheld. I can not change the value of the speed in the handheld remote. If I move to another part of the basement maybe I can get control, maybe not. Even placing the handheld right over the TIU will not gain control, like they are not communicating. Lots of heating ducts in the ceiling, are they causing a problem?
Thanks,
Greg
