@gilbo2 That's a very interesting fact about "Reset eLink on start=2". I don't know if you were aware of this, but, when RM starts up, it sends out to the track bus, a few commands for each loco in your loco group, ensuring that for each loco, the speed is zero, and all of the functions are off. Further, as part of the DCC protocol, the controller for locos (whether Elite or eLink) will thereafter continuously send out commands for each loco it has so far encountered, repeating the current speed and current settings (off or on) for all functions. I am wondering whether the "=2" setting causes the RM startup procedure to skip past sending out the initial commands for all locos in the group for the eLink, so that the output traffic to the track bus only grows in the number of locos whenever a new loco is selected during the current RM session. This would mean that the eLink might spend less time maintaining the output message traffic, or have more time to handle incoming commands from RM. Might also reduce the amount of memory used inside the controller itself. Just a thought or two ! Ray
