ProtoThrottle - additional features

A bit more detail about the ProtoThrottle's features, including reverser and brake options. A couple of corrections/clarifications regarding statements I made in the video: 1. The reverser config default for the PT is that the reverser sends a DCC "forward" command when the reverser is right and a "reverse" command when the reverser is left. Whether that matches the direction on your layout or not, depends on how the locomotive consists have been configured. Turning reverser swap ON swaps that configuration. 2. The variable brake feature doesn't take advantage of any features from the decoder manufacturers - it actually is implemented by ISE as a workaround because no decoder manufacturer has a truly real-time variable brake. The PT pulses the standard on/off brake function to get effectively less than full braking. The brake setting on ESU decoders just sets the strength of the on/off brake, which lets you adjust it at configuration time, but during operation the PT is still just pulsing it to get the "variable" braking effect. Same for Soundtraxx.
