Notes:
1) All connector pins are paired top (component side) and bottom (sol-
der side) except 11/M and 12/N. For 6 Amp current rating with 3 Amp
connector pins, track/zone wires must be connected to both pin pairs:
e.g. Zone A = pins 1 & A (See Figure 4).
2) Letters G, I, O & Q are not used as pin designations on the connector.
3) Power connections should be made to a power supply dedicated to
BDL162 use only. Multiple BDL162 units can be supplied by a single shared
supply as long as you provide at least 100mA for each BDL162.
4) The Ground connection, pin 11, must be made to the booster for correct
BDL162 operation.

To make set up simpler and easier for non-Digitrax layouts to use the BDL162,
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
BDL162. It is best that this signal stays active even when the booster output
is shorted or disconnected from the BDL162 zone inputs, for example by a
PM42 Power Manager.
3. Configure the BDL162 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 BDL162 will oper-
ate on direct home layouts (the factory setting). When DCC packets are
supplied 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
selected.
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 BDL162. 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 BDL162 is first powered up, the
BDL162 will be re-configured.
