I mistakenly posted this over on the Electronics forum
Pusher Service using Railboss
Hey Jon - i never actually tried this combination before, but it makes sense! Glad to see you are having fun with your RailBoss products. More in the pipeline 
Thanks Del - Did you read the other thread - It explains how I run the operation by switching the Plus board off-line with the loco select switch, then controlling the Enhanced board independently for switching.
Follow the link at the top of my first post to get to the other thread.
