The SE8c breakout board brings out all the connections available on the SE8c's edge connector. The multiple input breakout board for the BDL168 block detection eliminates soldering connections to the card edge or card edge adapter of this product. The single input breakout board for the BDL168 block detection eliminates soldering connections to the card edge or card edge adapter of this product.
If you have a need for a custom breakout board that needs a different physical footprint, custom inputs, wire terminals, or you would like to have a single board that will allow you to connect a PM42 directly to the BDL168 with no additional wires, we will work with you to design a solution to resolve your quandry.

This photo is BDL168 Number 5 (board address 102) in the wiring diagram in Section I of the Home Page. This photo shows BDL168 number 3 in the wiring diagram (board address 105) with two of the Detection Zones fed by a DCC Specialties OGAR (On Gaurd Automatic Reverser). Detection Zone 1 and 2 are fed by the DB200 and Detection Zones 3 and 4 are fed by the DCS100.
This shows BDL168 number 1 in the wiring diagram (board address 103) with three of the detection zones fed by a DCC Specialties OGAR (On Gaurd Automatic Reverser).
Section 103-9 feeds Reverse Loop 2 which is a passing mainline for both Destin and Dos Vias. At the facia switch the White common is the center connection and the brown up and the black down.
I bought all the parts and a good punchdown tool at Lowes and simply connected all the like terminals together on the back.
Direct Home Layout Wiring Digitrax strongly recommends direct home wiring where each power district and its booster are electrically isolated.
These board eliminate having to solder connections to your Digitrax(c) PM42, BDL168 and SE8c DCC accessory boards. Each output has a set of jumpers that allows you to set that particular section to reversing, assuming the correct OpSwitches have been set inside the PM42's memory.
This includes the 8 slow motion switch machine drivers, the 8 pushbutton inputs and the 8 sensor connections as well. This design has 4 inputs separate inputs, each tied to a specific detection zone; each zone has 4 individual detection sections. This design has a single input, meaning all 4 detection zones (and all 16 sections) are connected to a single booster, command station or DCC circuit breaker.
I have a Digitrax Super Chief system and will be using a PM42 for power management and a BDL168 for block detection.
I assume you will have another red line from SD2 to the common side of detection zone 2, and so on. Also, if you need more than 4 detection sections in a given sub-district, you can wire the PM42 output to more than 1 BDL-168 input.


You probably already realize this, but you each Detection Zone (DZ) doesn't need to have an exclusive Power Subdistrict (SD) feeding it.
You just plug the board in and the breakout board has screw terminals to attach the actual wires to. After the bundle leaves the board it is joined with the appropriate Black Track terminal wire from the Booster. You must have computer control to use the SE8C (or some other method to compute the signal logic).
The wiring diagram and description is on the Home Page Section I DCC Programming Track Drawing. To keep track of where everything goes, the upper left is always the incoming LocoNet Cable and the top right is always the outgoing cable to the next box. If you would like to detect a reversing section of track or use additional boosters all on a single BDL board, this is the product for you.
Multiple BDL168 units can be supplied by a single shared supply as long as you provide at least 100mA for each BDL168. I have been reading through all the Digitrax manuals plus about a zillion blogs and message boards and think I have my overall track wiring strategy mapped out. Therefore, there are bundles of 5 wires (track busses) that run under the tracks to which are connected the drop wires soldered to the track. Note, these are not the same as the pin identification numbers that are already molded on the connector. 4) The Ground connection, pin 11, must be made to the booster for correct BDL168 operation. I have posted a high-level diagram below--can y'all do a quick review and let me know if I have got this right? With direct home wiring, the BDL168 can determine and indicate whether any of its 4 zones is powered or not (possibly short-circuited) even when there is nothing on the rails in the detection sections.
Make sure to double check the connector orientation before plugging in the BDL168 board to avoid possible damage that can result if it is plugged in using the incorrect orientation.
Confirm that the 44-pin connector is plugged in to the BDL168 in the correct orientation to avoid damage to the BDL168 when power is applied. Detection Zones 1 and 2 are fed by the DB200 and Detection Zones 3 and 4 are fed by the DCS100.
The BDL168 factory-set logic causes the detection sections to show "occupied" if the associated zone's power is off (because in this case, detection is not possible). And it has been mentioned here before but the Accu-Lites Digitrax breakout boards are worth every penny! Also note that my turnouts at the ends of passing sidings are wired as independent blocks since I want to eventually have a prototypical CTC installation. Hint: Some users assign each BDL168 board a letter designation to use with the detection section number for tracking outputs.


By doing this, the turnout blocks will serve as interlockings or control points within the signal system. The Figure below shows an example of a direct home wiring layout with a single power district with multiple detection sections. Zone A with 4 detection sections (1-4) and zone D with one detection section (16) has been wired in this example.
This is in a sense overkill (although I think it eliminates certain kinds of wiring errors, at the cost of a few more feeder wires) and you don’t need to work this way to use a BDL168.
This keeps problems on one track from affecting others and problems in one part of the layout from affecting the same track elsewhere.
It also requires lots of electronics, and gives me lots of occupancy detection sections (which I like having).
To use transponding you need to use a Digitrax (or other) decoder that supports it, and turn the feature on (typically by setting a CV; see the decoder manual). The NMRA is working on a different, multi-vendor system called RailCom, but it’s not as mature as Transponding today. Even though the computer is old and a bit slow to load the software, I saw no problems with it during testing (I also did a few tests with a much newer Intel-based laptop for comparison).PM43 (left), BDL168 (right) and eight RX1 sensors ( labeled AA - BD here)Terminology and AddressingThe sixteen outputs of the BDL168 are numbered 1 to 16.
That’s annoying, but ultimately not a serious problem as this all gets hidden from the user inside the JMRI configuration. The maximum current-carrying capacity depends on heat, and limits are defined for wire in open air (which is what likely applies to most layout wiring) and in enclosed spaces (which could apply to a long feeder run within scenery). Digitrax’s own manual makes frequent reference to 12 gauge wire, which would be impossible to use. The application note suggests use of terminal strips to convert between the local and bus wiring, and this is what I used.
BDL168 with four LT5 LED sets: Block 2 (left) and block 12 (right) occupiedTransponding is a bit odd. And I had problems with a fifth quickly traced to the test-track feeder hanging too close to the sensors on the board. I tested for that using my decoder tester with a DZ123 decoder, a full size bright-white (high current) LED and a 470 ohm resistor, generating a current around 20 mA on a zone with just 100 mA (20% rather than 2%). The problem persisted, so I don’t think an undersize resistor on the decoder is the issue here.
I may just give up and write-off use of transponding for now so I can get back to making the occupancy detector boards and installing them. All of this makes clear that Lenz’s RailComm is their not-yet-quite-standardized choice for what they call Decoder Transmission.
