1 BDL168
1 44-Pin Connector
The BDL168 requires a 12V-16V AC or DC power supply which is sold sepa-
rately. Multiple BDL16 series detectors can be powered from the same power
supply as long as 100mA is provided for each BDL16 series detector. One
Digitrax PS12 power supply can run up to three BDL16 series detectors.
Digitrax Manuals and Instructions are updated periodically.

  • Page 4 BDL168; this enables 4 transponder zones on the BDL168. In this case, each transponding zone may encompass one to four detection sections. Each BDL168 can host an additional RX4 giving you a total of 8 transponder zones that can be shared across the available 16 detection sections of the BDL168.
  • Page 5 The form, BDL16 Series Planning Worksheet, is also available in the same section for documenting your setup for future reference and trouble shooting. Whether you are building a new layout or installing your BDL168 on an exist- ing system, there are two basic wiring formats: direct home wiring and whole layout common wiring.

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.

    3mA. If you use higher LED drive currents you can use external transistors etc to amplify the LED current. The LED drive from the BDL168 is active high at about +5 volts above the BDL168 ground pin, via a 1 Kohm resistor. Note that the ribbon cable includes separate ground return conductors for each LED that allow a 10 conductor rib- bon cable to be split into 5 pairs to conveniently route to individual LEDS.
