Q: What is the exact reset procedure for a TF4? I tried both with series 3 procedure (CV8) and the other mobile decoders procedure with no success. My TF4 remains out of control. However, the white output makes the LED on my decoder testing board flicker. A: Since CV8 to 08 only works on series 3 and later decoders, it does not work on the function only decoders. TF4's CVs must be reset manually to factory values. The Factory Default Values are: CV64 000 CV61 002 CV49 000 CV50 000
Q: Can I use non-Digitrax decoders on a Transponding layout?A: Yes. If you want to add transponding to a decoder that does not have the feature, add TL1 or TF4 to the decoder. Some non-Digitrax decoders that use supersonic features are not compatible with transponding unless you switch off the supersonic feature. Digitrax supersonic decoders are compatible with transponding and can be used in supersonic mode while transponding.
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 ...
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 ...
Installing the TF4 in the Loco or Rolling Stock1. Connect the TF4's RED and BLACK wires to the matching RED and BLACK track feed wires of an installed DCC mobile decoder.2. If the TF4 is used by itself, for example in a caboose or box car without a DCC mobile decoder installed, connect the TF4's RED wire to the right hand track pickup and the TF24s BLACK wire to the left side track pickup.3. No other parts are required to set up the transponder current pulses, since this is self-contained in the TF4.4. Install the lamps using the TF4's blue, ...
Program the TF4's Address & Function Outputs1. Before using your TF4, set its address. This may or may not be the same address as a mobile decoder already installed in the loco or car depending on how you are planning to use the TF4. In the case of TF4's being used as a stand alone transponder or as a function decoder, choose an address that is not the same as another mobile decoder address in use on the layout.2. Connect the RED & BLACK wires of the TF4 to a service mode DCC programmer and program the TF4's address as ...
A TF4 can be used with any decoder that is not transponder equipped to add transponding capability to the loco. It can also be used in any piece of rolling stock with track pick ups to add transponding. For example, you could use a TF4 to add transponding and lighting effects to a caboose if it is equipped with track pickups to provide power and signal to the TF4.A TF4 should not be connected to an existing transponder equipped DCC decoder unless the DCC decoder's transponder is disabled. This avoids having 2 transponders responding to the same address in the ...
