HO GE 44 Ton Switcher

[gem629]

I have a HO GE 44 Ton Switcher (Strasburg RR #33) Soundtraxx Tsunami2 Dcc Sound equipped #68203. I am trying to put this engine in my Roster in decoder pro, but decoder pro cannot read back the decoder, but it is asking me to manually input the decoder, but I cannot input it because I do not have the model number of the specific decoder that is in the engine. Can you provide me with the information so I can complete my roster. Thank You
