1. Install BDL16 series occupancy detector(s). BDL16, BDL162 and BDL168 occupancy detectors can be used together on the same layout.2. Add RX4 transponder receivers to the zones you want to set up for transponding. (You won't need to cover every detection section on the railroad for effective coverage and reporting. Some areas will be detection only sections while others will have full transponding as needed.) Use either two RX4s with your BDL168 to set up 8 transponding zones or use one RX4 if you only need 4 transponding zones.3. All current production Digitrax decoders are transponder equipped. If you have decoders ...
When the BDL168 is connected to LocoNet, it will communicate coded detection information to the system. If you wish to report BDL168 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 BDL168. This is done so that the BDL168 Board ID does not conflict with the Board ID of other devices on the railroad. Board addresses can range from 01 to 999. It is recommended that you make a record of the addresses you use for all devices connected to your layout. Setting ...
My question is: How do I mount the PM42? Do I need a special housing in order to mount it under table? It appears to me that mounting it flush against a surface would prevent, or make it extremely difficult, to attach the 44-pin connector. Digitrax manufactures three devices which have a 44-pin connector. These are the BDL168 (and its predecessor the BDL16), the SE8C and the PM42 (and its predecessor, the PM4). These best approach to mounting these devices is to screw the connector directly to the wiring panel board. Drill mounting holes in the end of the 44-pin ...
How to read back and change BDL168 Option Switches (OpSw): 1. Power up your BDL168 and connect it to LocoNet. 2. Connect a DT series or UT1, UT2 Digitrax throttle to one of the the BDL168's LocoNet connectors. NOTE: The UT4 will not work as its design is different for the original UT series throttles.3. Press the switch behind the red option LED for about 1 second, then release it. The red option and green ID LEDs will flash alternately to let you know that you are in option switch setup mode. 4. Go into SWITCH mode on your throttle. ...
The option switches and settings you can use to customize your BDL168 are indicated in the table below. These option switches on your BDL168 are set up using a Digitrax throttle's SWITCH commands. (This can only be done with a Digitrax LocoNet throttle or equivalent software). SWITCH mode is normally used for operating turnouts by issuing closed ("c") or thrown ("t") commands. In the case of your BDL168, each switch address is a BDL168 option switch. The following table shows what each OpSw is used for when it is set for thrown or closed. Factory settings are indicated by shaded ...
The BDL168 is designed to be used with power management devices such as PM42. The BDL168 is designed to operate “downstream” of the Digitrax boosters and power management devices. The BDL168 is the "last" device in the chain from booster to power manager to BDL168. It is connected directly to the track detection section. There should be no other connections to any detection section that will draw track power or the detection section will always show occupied. If a device is used to switch off power feeding the BDL168 and the track it is connected to, for example, a PM42 ...
The BDL168 does not require a heatsink to operate efficiently, however, large scale operations may generate higher heat levels with the BDL168 and you can make your own to add to the unit. The BDL168 design does not include a provision for a heatsink. There is not a kit available for adding on a heatsink, but you can make your own if you believe it necessary for your system. The following drawing will provide the correct measurements to produce a heatsink that will slip in between the two rows of rectifiers on the BDL168 Circuit Board. This will raise the ...
Reducing Sensitivity for Outdoor Layouts Outdoor layouts may require reducing sensitivity to allow for more accurate occupancy reporting through the BDL168. Resistors are connected between the detection zone and the zone common from the blue connector to reduce sensitivity. A 1KOhm resistor will reduce the sensitivity by 1/2. A 100 Ohm resistor will reduce sensitivity by a factor of 10.
BDL168 Pin Out Configuration: Notes: 1) All connector pins are paired top (component side of the BDL168) and bottom (solder side of the BDL168) except 11/M and 12/N. For 6 Amp current rating with 3 Amp connector pins, track/zone wires must be connected to both pin pairs: e.g. Zone A = pins 1 & A (See Figure below): 2) Letters G, I, O & Q are not used as pin designations on the connector. 3) Power connections should be made to a power supply dedicated to BDL168 use only. Multiple BDL168 units can be supplied by a single shared supply ...
Common Rail Wiring Many older model railroads use Common Rail wiring because they were initially wired to operate with electrical toggle switches. Conversion to DCC is possible with Common Rail, but it is not recommended. Whole layout common rail is a method of wiring layouts where power districts and their boosters are electrically connected using a common rail or common power bus return wire. Whole layout common rail wiring is a disadvantage when it comes to detection systems since detectors cannot independently monitor whether zone power is on or off so they can't tell whether occupancy detection is working in ...
Direct Home Layout Wiring Digitrax strongly recommends direct home wiring where each power district and its booster are electrically isolated. This method of wiring has safety advantages and makes troubleshooting problems easier. In addition, direct home wiring makes detection work more prototypically. 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. 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 ...
Here are some terms that you might find useful as you work with the BDL168. Direct home wiring is a layout wiring method where each power district and its booster is electrically isolated. The track within each power district uses a "common return" wiring method for occupancy detection and/or power management. Direct home wiring is the wiring method recommended by Digitrax for safety reasons & also because it makes detection work more prototypically. Power district is the power wiring, track, components and equipment attached to that wiring, driven by a single properly isolated booster. The track for a power district ...
The BDL168 manual states that 2 RX4's can be connected but it only shows how to connect one of them on Aux 2. How is the second RX4 connected? The RX4 is a 4 Zone Transponding Receiver Add-on for BDL16 series occupancy detectors. Each RX4 is made up of 4 RX1 sensors, a ribbon cable and a connector that lets you plug the unit into a BDL16-series detector. The earlier BDL16 and BDL162 occupancy detectors had the capacity for hosting one RX4. BDL16 & BDL162 boards are labeled with AUX1 & AUX2. Only the AUX2 connection should be used for ...
Is it possible to connect my BDL168 across two power districts (Boosters). I envisage using zone 1 & 2, with detection sections 1-8 one one booster (DCS100), with zones 3 & 4, with detection sections 9-16 on another booster (DB150). Will this work? Please refer to the chart below: Note that Pins 1 & A, 6 & F, 13 & P, and 18 & V are identified as "Connection to Booster for Zone *. Each Zone can support up to four detection sections. So, for your application, the DCS100 would be connected to Pins 1 & A and 6 & ...
What is the physical size of the BDL168? The board itself approximately measures 3 3/4" wide by 3 5/8" long by 1 1/4" high. For those who use metric, it is 94mm by 92mm by 30mm. In addition to the board itself, the edge connector measures 4 1/32" (112mm) by 3/8" (10mm); it has edge connector pins which make the connector 5/8" wide (18mm). The edge connector pins will need additional clearance for the connected wires. Users have found that the heavier bus wires used in most applications are difficult to connect to the edge pin connector; in ths situation, ...
