I guess I should add that my legacy base alone can’t drive really more than 6 devices reliably. You can get 7 devices working but one drops out every so often. After a long fight with Lionel Customer Service who indicated that only 3 devices are officially supported, I decided to take matters into my own hands and purchased a 232LBR9 signal amplifier from B&B electronics. I now have 14 devices connected to one legacy base and working flawlessly. I don’t know what the limit is with the signal amplifier, but I’m pretty sure I can add a few more devices without a problem.
Lionel insisted that I was the only one who had an issue with the limitation. It seems to me that comprehensive testing of serial based devices was left out of the development loop for legacy. I don’t understand why I am so unique. I use a TPC for every block, and a serial device to control every accessory. It’s not hard to get to 14.
