I had some time this morning and this is what I found in my tests.... using a ERR Cruise Commander and RailSounds 5.5 board from a ATSF E6 Atlantic.
- The ERR R4LC board that is included with the kit, does not put out a 9 bit serial data. Only 8 like John and GGG were saying.
- The Legacy R.S. Board in this case the 5.5 version did see the 8 bit and will operate in TMCC mode with no quilling whistle feature.
- I put a Lionel R4LC board a true 9 bit board from the E6 Atlantic on the ERR cruise commander. I did get lighting and coupler control but no motor control in LEGACY Control Mode. But I did get Legacy RailSound control (Quilling Whistle)
- Now, If you go into the #900 LEGACY Cab-2 Controller and set the engine to TMCC control and then set the Sounds to LEGACY. You will be able to control the motor function with the Lionel 9 bit R4LC and also be able to control the LEGACY Sound features such as the Quilling Whistle/Horn.
- Have not tested this with the CAB1-L. I don't have one. I don't know if it is possible due to the basicness of the controller system.
