The Digitrax RX4 is a top - notch 4 - zone transponder detector designed for use with Digitrax occupancy detection systems. It allows you to not only spot which blocks are occupied but also recognize what's inside. With the RX4, you can precisely know the layout zone location of locomotives and rolling stock equipped with transponders. Each unit handles 4 transponding zones efficiently. Its low - current pulses won't cause interference with DCC decoders or other track signals. It can be combined with other occupancy detection methods to customize your layout's feedback system. Compatible with most DCC systems and can be adapted for other command - control systems too. Location and identification data are continuously updated on LocoNet and can be set to display on a track diagram. You don't need to modify existing equipment; just add the transponding components and you're good to go. It offers more features than other 'bi - directional' communication methods. Note: RX4s must work with a Digitrax BDL16 series occupancy detector to function. Suitable for use with BDL168, BDL162, and BDL16.

Using the Digitrax RX4 is quite straightforward. First, make sure you have a Digitrax BDL16 series occupancy detector as the RX4 needs to work with it. You don't have to modify your existing equipment; simply add the transponding components to get started. Once installed, the RX4 will start detecting occupancy in 4 zones. It'll continuously update the location and identification information on LocoNet. You can configure it to display this location data on a track diagram. When it comes to maintenance, keep it in a dry and clean environment. Check the connections regularly to ensure there are no loose wires. If you experience any interference issues, check if the low - current pulses are being affected by other devices. Overall, it's a great addition to your model train setup and will enhance your occupancy detection experience.
