I am trying to program the decoder using JMRI and a DCC++ control setup. The locomotive appears to talk properly with JMRI. Doing  a read the decoder I am offered two choices 2 function and 4 function since this is a fairly basic locomotive I assume its the 2 function version. I go through the normal steps to assign it a road number and decoder number. I can see the loco is communicating.

I do the write and save I ask for it to be read back all seems fine but the loco will just sit and not respond to the JMRI throttle after programing. It is no longer responding to 3 but also is not responding to the new address. I did try the four function decoder set but ti doesn't seem to be any more successful.

So A what decoder is this? Second any suggestions on what is going wrong. I had no trouble programing the Withcomb diesel I have using this setup. I am at my wits end with this.
