Product Support for: Transponding -> 4-Zone Transponding Receiver Add-on for BDL Series Detectors (RX4)

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 ...

Operations mode (OPs mode) programming allows you to program decoders on the layout instead of having to move them to a separate programming track.  This is a write only programming method.  If you want to be able to read back the values written to a particular decoder using Ops Mode programming, you will need to install transponding on the layout.  If transponding is not active on the layout, you must use an isolated programming track for reading back CV values.The extent of the area with OPs Mode readback available depends on how muchof the layout is instrumented for transponding. The ...

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 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 ...

Is it possible to add a pair of PM42 Power Management Modules between the command station Rail A/Rail B outputs and run the resulting output from the PM42's on as many as 8 sets of Rail A/Rail B Wires to 8 isolated power Zones? These isolated power zones could have their Common Zone (Rail A) Wires running through RX1 transponding receivers connected to an RX4 ribbon cable running to the BDL168 for the purpose of interfacing with the SurroundTraxx Multi-Train Sound System. If this is possible, it would only require 5-6 of the DS lines on the BDL168 to be ...

Digitrax Complete Train Control By Zana & A.J. Ireland Digitrax Complete Train Control makes reliable, realistic train operation and simplified layout wiring a reality. Digital Command Control is incorporated within the Digitrax system to let you control multiple trains independently on the same section of track without blocking. In the real world, engineers control the speed and direction of real trains. Engines operate under their own power independent of the track. Each engine has its own motion characteristics like how fast it speeds up (acceleration) and how long it takes to slow down (deceleration). A locomotive's performance is influenced by ...
