Program the TF4's Address & Function Outputs
1. 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 you would any mobile decoder address.
TF4 Default Settings:
The TF4 can be programmed with a 2 digit or 4 digit address. Remember to set CV29 to the appropriate value per your Decoder Manual for 2 digit or 4 digit operation. For 2 digit addressing CV29 is most commonly set to x06/006 decimal. For 4 digit addressing, CV29 is most commonly set to x26/038 decimal.
3. Set up which function numbers control the TF4's white, yellow, green & violet function leads. Program values for CV61 & CV64 per the table below:
4. The TF4's white and yellow leads can be configured for a strobe effect with a value between 00 & 07 into CV49 for the white lead and CV50 for the yellow lead. (please see table, below). The green & violet lead can be used for standard on/off functions only.
5. The rate of these configured effects can be changed by programming a value between 00 & 07 into CV62 for the white lead and CV63 for the yellow lead. Please see table below.
6. When programming is complete, exit programming mode. Test for correct operation of the function after you install the TF4 in the locomotive.
7. Programming a TF4 after it is installed in tandem with a DCC decoder may yield unexpected results because of differences in the way various DCC decoders respond to programming. If you are not able to program your installed TF4, first try a different programming method. If this does not work, remove the TF4 and program it separately on the service mode track, then reinstall it in the loco.
