5.1 Wiring the BDL168 for a Digitrax Direct Home Wiring Layout
1. After mounting the 44-pin connector to the board (see section 4.0), label the
top of the 44-pin connector for easy identification of the wires, using zone
letters (A,B,C,D) and detection section numbers (1-16) (See
Figure 1
).
Note, these are not the same as the pin identification numbers that are
already molded on the connector.
Make sure to double check the connec-
tor orientation before plugging in the BDL168 board to avoid possible
damage that can result if it is plugged in using the incorrect orientation.
Hint
: Some users assign each BDL168 board a letter designation to use
with the detection section number for tracking outputs. For example the first
BDL168 board would be “A” and the detection sections connected to it
would be labeled “A1”, “A2”...“A16” on the wiring panel terminal strip, on
the rough layout and on the layout diagram for easier troubleshooting.
2. Solder one wire (AC1) from a 12-16V AC or DC power supply to the pin
12 and the second wire (AC2) from the power supply to the pin N on the
BDL168's 44-pin connector. This powers the BDL168. Multiple BDL168
units can be supplied by a single shared supply as long as you provide at
least 100mA for each BDL168. This power supply should not power any
devices other than BDL168s.
3. Solder the ground wire from the Digitrax booster ground or common (case)
to pin 11 of the 44-pin connector. Nothing is connected to pin M.
4. The end of the wire from each zone common and detection section should
be stripped approximately 1/4” and inserted through the holes in each pin
pair on the connector as indicated in
Table 1 and Figure 4.
Solder the wire
to each pin. The zone common connections to the booster should be as short
as possible and relatively heavy gauge, since they are common to all four
detectors in the zone. For example, a 12AWG zone connection to the boost-
er should be less than 10 feet for best performance.
5. Plug the BDL168 board firmly into the 44-pin connector.
6. Connect a LocoNet cable into one of the BDL168's LocoNet jacks.
7. Apply power to the unit. The red and green LEDs will light up as power is
applied to the unit. The red LED will go out and the green LED will stay on
and “wink” off once, approximately every 2 seconds, indicating that it is
connected to LocoNet and seeing DCC packets.
The BDL168's option switches are factory set at the values that will work for
most direct home wired layouts. You can fine-tune the BDL168's characteris-
tics using its option switches which can be set using a Digitrax compatible
throttle or a PC with LocoNet compatible software that can control turnouts.
See Section 7:
"Customizing your BDL168 By Setting Up Option Switches.
