Digitrax UR90 Infrared Receiver Panel
The UR90 is the IR receiver unit. The UR90 also looks similar to a UP5 and is mounted in the fascia of the layout.
The UR90 is simply an addition to your existing LocoNet so no additional wiring is needed. The UR90 will support approximately 10 Infra-Ready throttles. Most layouts will need more than one UR90 because IR is line of sight and the receivers must be able to "see" the IR signal. UR90 & UR91/UR92 can be used together on your layout to provide both wireless methods at the same time.
