detection sections.

The BDL16 incorporates current setting resistors to set the LED current typi-

cally about 3mA. If you use higher LED drive currents you can external tran-

sistors etc to amplify the LED current.

The LED drive from the BDL16 is active high at about +5 volts above the

BDL16 ground pin, via a 1 kilo-ohm resistor. Note that the ribbon cable

includes separate ground return conductors for each LED that allow a 10 con-

ductor ribbon cable to be split into 5 pairs to conveniently route to individual

LEDS. Be sure to connect the +ve active output leads to the LED anodes.

10.0 BDL16 Board Address

When the BDL16 is connected to LocoNet, it will communicate coded detec-

tion information to the system. If you wish to report BDL16 status to LocoNet

and attached devices or computers that can interpret these messages, you will

probably want to set up a unique board address for each BDL16.

10.1 To set up the board address

1. Power up your BDL16.

2. Press the switch behind the green ID LED for about 1 second, then release

it. The green ID LED will blink. The red option LED will not light. This let's

you know that you are in board address set up mode.

3. Connect a DT or UT series Digitrax throttle to the BDL16's LocoNet con-

nector.

4. Go into SWITCH mode. Dial up the switch number that corresponds to the

board address you want to set and issue a closed "c" command to set the board

address. The board address is changed as soon as you issue the SWITCH com-

mand. See below for instructions for specific Digitrax throttles.

DT100 or DT200 series throttle, press "MODE/DISP" on the throttle to enter

SWITCH mode. Use the throttle dial up the board address you would like to

assign to the BDL16. When the address is in the display, press "c" to issue a

closed command. This will set the board address for the BDL16. The green

LED will then go steady green to indicate BDL16 Power on.

UT series throttle, press RUN/STOP and DISP/OPSW at the same time to

enter SWITCH mode. With a UT throttle, dial up the board address you would

like to assign to the BDL16. Press the "c" key until the corresponding LED is

lit. This will set the board address for the BDL16. The green LED will then go

steady green to indicate BDL16 Power ON. When you are finished setting up

BDL16's board address, return to LOCO mode by pressing RUN/STOP and

DISP/OPSW at the same time to exit SWITCH mode.

11.0 Troubleshooting: Checklist

11.1 Packet Reception

Be sure the green ID LED is ON & is "winking" off about every 2 seconds.

This means that correctly formatted DCC packets are being decoded from the

left most (Railsync) pin of the RJ12 LocoNet socket. For DCC detection, the

same DCC packet signal that drives the booster must be connected to the RJ12

socket's leftmost pin. If you are using LocoNet, and you do not see the green

LED blinking pattern described, check to be sure that the system is powered up

and that your LocoNet cable connections are good. You can use your LT-1 to

test the LocoNet cables if you suspect there is a problem with them. If the

green LED on the BDL16 is not lit, check the external power connections.

11.2 Mode Indication

The winking on the green ID LED indicates the primary BDL16 mode. A sin-

gle wink indicates standard Digitrax compatible Direct Home track wiring and

detection logic will be used, a double wink indicates Common Rail wiring and

detection logic is to be used. For Common Rail, all 4 BDL16 zone connections

must be made to the System Common ground point. Be sure the BDL16 con-

figuration is appropriate for your usage.

11.3 Occupancy Debug

Use the LT5 provided with your BDL16 as described in Section 9.1. You can

also build a simple LED display debugger as follows. Use a 10 pin plug and

cable such as DigiKey (1-800-DigiKey) part number M1AXA-1036R-ND that

will plug into one of the 4 occupancy LED headers on the BDL16 and solder

LEDs to the wires to create an array of LEDs. By plugging this display array
