5.1 Wiring the BDL162 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.

Hint: Some users assign each BDL162 board a letter designation to use

with the detection section number for tracking outputs. For example the first

BDL162 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

BDL162's 44-pin connector. This powers the BDL162. Multiple BDL162

units can be supplied by a single shared supply as long as you provide at

least 100mA for each BDL162. This power supply should not power any

devices other than BDL162s.

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 BDL162 board firmly into the 44-pin connector.

6. Connect a LocoNet cable into one of the BDL162'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 BDL162's option switches are factory set at the values that will work for

most direct home wired layouts. You can fine-tune the BDL162'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.

5.2 Wiring the BDL162 for Whole Layout Common Rail Wiring

Whole layout common rail wiring cannot independently monitor whether zone

power is on or off so it can't tell whether occupancy detection is working or not

in any given detection section. The BDL162 can be easily configured to over-

come this disadvantage by using detection section 16 to monitor track power--

if track power is on in section 16 then detection is working in sections 1-15.

1. After mounting the 44-pin connector to the board (see section 4.0), label the

connector Using the zones and detection section numbers for easy identifi-

cation of the pins when wiring. (See hint on labeling for wire tracing and

troubleshooting under 5.1.1 wiring for direct home wiring systems.)

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

BDL162's 44-pin connector. This powers the BDL162. Multiple BDL162

units can be supplied by a single shared supply as long as you provide at

least 100mA for each BDL162. This power supply should not power any

devices other than BDL162s.

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 detection section and zone common 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. Wire a 10K resistor from detection section 16 (pin 22) to the detection com-

mon return for the whole BDL162 ( Figure 2). Detection section 16 will be

active when the BDL162 sees track power and you will be able to tell

whether detection is actually available in detection sections 1 through 15.

6. Plug the BDL162 board firmly into the 44-pin connector.

7. Connect LocoNet via one of the BDL162's LocoNet jacks.

8. The first time you apply power to the unit, hold down the switch located

behind the red LED on the BDL162 to set it up for whole layout common

rail operation. 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 twice, approximately every 2 seconds, indicating that it is set up

for common rail wiring and that it is connected to LocoNet and seeing DCC

packets.

The BDL162's option switch 10 is set to

16 to be used to monitor zone power on a whole layout common rail wired sys-

tem. You can fine-tune the BDL162's characteristics 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 BDL162 By Setting Up Option Switches."
