About 3 years ago I purchased a second Legacy control system based on advice provided here that I most likely had a defective remote with the older version. Older version is 1.3?; newer is vs 1.52. Main problem with older remote was malfunctioning reverse plus a few other issues. Thus, I bought a newer system and relegated the old to operating two pair of remote switches on my Christmas layout, which it worked fine. Never got around to adding my engines to the new Legacy unit until now. I recently bought a new Legacy Polar Express Berkshire, cab #1225. Decided to add that one first. Opened the engine owner’s manual to see the steps required to get the engine going in Cab 2. The instructions appeared simple enough, but did not work. The remote came on as Cab 1 and the center touch screen did not work. Note that no mention of using the prgm switch beneath the engine in the initial start up instructions. The program switch is first mentioned in the manual 4 pages later and the wording indicates it is used to change the engine ID #. I left the switch in run mode as it was set at the factory. The only sign the engine was alive was the two engine # boards on front were lighted. Should I have switched to program mode? Did not want to do that until I consulted here. If that is the issue, then great. Otherwise, please provide some guidance as what to do next.
