Product Support for: Detection & Signaling -> LocoNet Occupancy Detector, 16 Detection Sections (BDL16)

RD2 Remote Sensing Diodes for BDL16 series occupancy detectors

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 ...

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 ...

Security ElementsThe Digitrax Signaling System is organized around the concept of what we call "security elements", which are similar to what U.S. prototype railroads call "plants" or "interlockings". The Digitrax SE8C signal decoder displays aspects for up to 32 heads for 8 individual security elements (plants) using either a LocoNet Throttle or a computer with compatible software. When used with associated occupancy detectors and compatible software, the SE8C can be set up to protect the turnout with signals as shown by the example below. Note that trains can move from A to B, A to C, B to A or ...

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 ...

Testing the installed TF4 for correct transponder operation1. Place the unit with the installed TF4 on an empty transponding track section. This test assumes that the transponding track section is already set up, tested and is working before you start TF4 testing.2. Using a DCC throttle, select the TF4 address that was programmed into the TF4 and verify that the transponder detector identifies the presence of the transponder device. Depending on how you have set up your transponding reporting to the system, your system should detect the presence of the address in that transponding section.For example, if you have an ...

If I use a non-Digitrax compatible system, what features of the PM42 Auto reverse/Short Circuit Managers (SCM) will I lose?The PM42 can be used as a stand alone Auto reversing unit and Short Circuit Manager with many other non-Digitrax systems, but for systems without LocoNet capability a number of networked management features will not be available.For example, the PM42 sends out real-time, event driven (non-polled) information to the LocoNet about fault problems and resolution, auto reverse actions and also identifies the affected sub-districts. This allows other devices, such as PCs, the Digitrax Signaling system, Digitrax Transponding or other detection and ...

  Do you have a recommend wiring procedure for the 44-pin edge connector on the PM42 and SE8C?PM42, PM4, BDL168, BDL16, BDL162 & SE8C use a 44-pin edge connector. Connecting wires securely to this connector requires soldering skills. For connections to the 44 pin connector, Digitrax recommends using 16 gauge stranded wire. For all other soldering connections, Digitrax recommends 14 gauge (AWI) stranded wire for electrical connections on your railroad. 1. Use individual short lengths of 16 gauge wire to connect to the 44 pin connector. 2. Strip and tin both ends of the wire. 3. Bend one end into ...

Digital Command Control (DCC) has specific electrical requirements that must be provided for your layout control system to operate properly.Input PowerAll DCC systems require an external power supply.  Digitrax manufactures several power supplies for our command stations and boosters: The 3 Amp PS415 (the Zephyr Xtra power supply) The 5 Amp PS515 for all Digitrax 5 amp command stations and boosters The powerful 20 Amp PS2012 can be used for multiple 5 and 8 amp command stations and boosters  Additionally, the PS14 is available to power various other devices for your railroad.  Digitrax strongly encourages you to use our power supplies to insure satisfactory ...

The Kelana Jaya Rail Line model is a DCC intense layout, using many Digitrax command control components to achieve the goal of training operators of the actual rail line. The railroad was built in the 1990's and many of the Digitrax devices used for the Kelana Jaya Rail Line model have been superseded with improved units. Components used for the Kelana Jaya layout: 28 Mainline turnouts 11 Yard turnouts 39 Tortoise switch machines 84 Dwarf signals (yellow/green, red/green, red/yellow) 38 Mainline block signals 38 Heavy duty SPDT switch relays Digitrax Components Used for the Kelana Jaya layout: 1 DCS 100 ...

We recommend testing your new SE8C prior to installation on your layout. The following testing procedures will help familiarize you with the general operation of the SE8C. Track power needs to be ON, a working LocoNet connection and a throttle or PC running DCC control software. Pre-Installation Set-Up 1. Solder one wire from a 12V AC or 15V DC power supply to Pin 3 and the second wire from the power supply to the Pin C on the 44-Pin edge connector; this powers the SE8C. Digitrax manufactures the PS14, which is appropriate for this installation. Multiple SE8Cs can be powered ...
