8.0 Auto-Reversing
Note that an auto-reverse section can only use detection sections that are con-
tained in a BDL16 zone that is correctly set up for auto-reversing , see Figure
3: Reverse Section Wiring for a wiring example.
9.0 LED Occupancy Indicators
9.1 LT5 Tester
Each BDL16 comes with an LT5 that will help you with layout wiring and
troubleshooting for transponding & detection with Digitrax BDL16 LocoNet
Occupancy Detector. The LT5 plugs onto the LED Connections of BDL16 and
the LEDS on the LT5 light when detection sections are occupied. The status of
power to each zone is also shown.
9.2 Panel Indicator Wiring
For a front panel display of status with user supplied LED’s, connect to the
four 0.1” 2x5 headers, and wire up LEDs as shown in Figure 4: LED Panel
Indicators Wiring. DigiKey (1-800-DigiKey) part number M1AXA-1036R-
ND is a convenient plug and cable assembly that you can use to wire LED
indicators. Header “A” includes the 4 detection indicators for detection sec-
tions 1 to 4 and the zone power indicator for zone A that includes these four
