The BDL168 is designed to operate “downstream” of the Digitrax boosters and
power management devices. The BDL168 is the "last" device in the chain from
booster to power manager to BDL168. It is connected directly to the track
detection section.
There should be no other connections to any detection
section that will draw track power or the detection section will always
show occupied.
If a device is used to switch off power feeding the BDL168 and the track it is
connected to, for example, a PM42 Power Manager, it should break the track
power to both the zone and detection common rail. If a device only switches
off a single leg, then it must be placed in the detection common rail wiring.

The BDL168 can report occupancy information via the LocoNet connection or
via direct output to a user created LED panel.
11.1 LocoNet Devices
The BDL168 provides occupancy messages to LocoNet that can be used by
computer software for a visual display of occupancy status on the layout or to
other devices on the layout. For instance, the Digitrax SE8 or SE8c can use
these messages to control signals on the layout. See the operations manual of
your computer software or the SE8C for details on installation and operation.
11.2 LT5 Tester
Each BDL168 comes with an LT5 that will help you with layout wiring and
troubleshooting for transponding & detection. The LT5 plugs onto the LED
connections of BDL168 and the LEDS on the LT5 light when detection sec-
tions are occupied. The status of power to each zone is also shown.
