Basic Process to Program DCC Accessory Decoders

Programming a DCC accessory decoder differs from maker to maker, but the basic process is the same: the entire process is done with the power ON.

 The device needs to be put into “programming mode.” This is usually done by adding or removing a jumper, a small wire, or pressing a setup button. Then, you typically have a certain length of time to complete the process before the device times out and stops listening. One important detail is whether the board requires you to ENTER programming mode with the power ON or OFF. It can be either one. NCE components are designed to enter and leave programming mode with the power ON.

1. While the device is “listening,” you use your DCC system to send a command to the desired accessory address. On the NCE system, this means using “select accy” and entering the number, then pressing enter.
2. You then complete the process by going through the motions of “throwing the switch” by selecting (1 or 2 )  (N or R) on the cab—it does not matter which one.
3. Once the DCC system sends the command, the new device captures the new address and stores it in memory.
4. The board is now programmed.
5.  If you had to add a programming jumper, remove it now
