Instructions
Install a Digitrax transponder device to detect occupancy. Transponding devices emit low-current pulses of electricity that are detectable by receivers mounted on the trains. The transponder detectors will detect a signal burst and move the tracks in a certain way or stop the train, if needed. Transponders can operate on different radio frequencies, allowing you to use multiple transponder systems concurrently.
Install an occupancy detector in your Digitrax track control system to alternatively detect occupancy. These devices connect directly to the track's main controls and detect any locomotive that's being powered. It also detects un-powered rolling wheels that are equipped with electronic resistors.
Plug the Digitrax occupancy detector into the open serial port on your Digitrax LocoNet track control system to install the occupancy detector, which will automatically configure itself to determine how many locomotives are in operation.
