@Mike CT posted:Have two Atlas SD 35's, one, the R2LC 07 board, that failed. I replaced it, with an R2LC08 board, available at that time. There were some differences, associated with detail lighting, requiring small wiring changes. IMO Mike CT.
Edit/add: These models also came with a blind driver axle set, that could be swapped-out, with the installed center flanged driver axle, on the SD trucks, for operation, on smaller diameter curves.
Mike—thanks for the info on your Atlas SD-35 upgrade. You mentioned some differences with some detail lighting when you went to the R2LC-08. I have noticed that my red marker lights do not function anymore now that I’ve done my CC-M upgrade and swapped in a new R2LC-08. My original DCDR board did not have any connections for the marker lights and so the only wire I have going into the 10 pin connector on the new CC-M board is the serial in from the R2LC and that is connected to pin 1 of the that connector. The CC-M directions have pins 3 through 6 as being outputs for the marker lights but again, my original DCDR did not have outputs for the marker lights so I’m at a loss as to how to get my marker lights working again. Any insight?
