Once in awhile it happens.

I received a LM-1 dirt cheap so cheap I couldn't pass up the deal.  I hadn't done any research before buying the LM-1 and never gave it much thought as to it's capabilities. It had a wiring harness that I have to replace as a few wires are cut off too short. I was surprised that there was two purple wires coming out of the module with a plug attached.  I really didn't know that it had sound? So as far as I know which is next to nill, LM-1 were only sound? Could this be? TOF in Yuma Arid-Zona HOT

Glenn   I found that on RP's website just a few minutes ago. I was surprised about the sound. I thought about using this LM-1 on a On30 diesel switcher that only needs control and lights but now I'll see what about diesel sound.  I might get a chance tomorrow morning to plug it in and see what happens. Follow up soon ------ TOF

They have sound, but very limited storage capacity, so it will not hold the ultimate sound files. There is a recent update for the light files. Check the updates on RPA.
