To make set up simpler and easier for non-Digitrax layouts to use the BDL168,
there are two quick configuration buttons that let you set up your unit to work
with either direct home or whole layout common rail without using a Digitrax
throttle or computer.
1. If you are using direct home wiring, use Section 5.1 as an example for
wiring detection sections. If you are using whole layout common rail
wiring, use Section 5.2 as an example for wiring detection sections.
2. Connect the left-most pin of the RJ12 socket (the RailSync pin) to Rail A
output of your system.The source of the DCC signal must match the DCC
signal being sent by the booster to the detection sections handled by the
BDL168. It is best that this signal stays active even when the booster output
is shorted or disconnected from the BDL168 zone inputs, for example by a
PM42 Power Manager.
3. Configure the BDL168 for your wiring system
a) For direct home wiring layouts, the “ID” switch behind the green ID
LED is held down when AC power is first applied, the BDL168 will operate
on direct home layouts (the factory setting). When DCC packets are sup-
plied to the RailSync pin of the RJ12 connector the ID LED will be lit and
“wink” off once every 2 seconds to indicate direct home operation is select-
ed.
b) When operating on a whole layout common rail system, the “OPTION”
switch behind the red option LED is held down when AC power is first
applied to the BDL168. When DCC packets are supplied to the RailSync
pin connector the ID LED will be lit and “wink” off twice every 2 seconds
to indicate whole layout common rail operation is selected.
Note: If either switch is pressed when the BDL168 is first powered up, the
BDL168 will be re-configured.
4. To make multiple BDL series detectors work with non-Digitrax DCC lay-
outs, they must be connected via LocoNet. One of the BDL series detectors
must be set up as a master by setting OpSw 11 to thrown (See Section 7 for
information about setting option switches). This allows LocoNet to commu-
nicate occupancy status to a computer.
