Hooking up the UP/UR’s Track Status Indicator-Optional
The UP/UR's Track Status Indicators are bi-color LEDs that show the status of
the local track section to which it is attached.
1. Attach an 18-26AWG wire to one of the screw terminals on the back
of the UP/UR & connect the other end to either rail.
2. Attach another 18-26AWG wire to the other screw terminal on the
UP/UR & connect it to the other rail of the track.
3. If you are hooking up more than one UP/UR, be consistent in hooking
up all track sections alike with respect to which terminal is connect-
ed to which rail. This is not required but strongly recommended.
As you operate your layout, the UP/UR Track Status Indicator will be lit when
the track is powered. The LED glows red or green when you are operating an
analog locomotive and the system is "zero stretching." When you are using
DCC only, the LED will glow orange. This color change is a useful diagnostic
tool.
