You can still use your SC-2 for switch and accessory control. But, if you want to see the position of a switch on your iPad or iPhone after an engine goes thru the switch and activates the anti-derailing feature, then you will need the new, not out yet, module STM2 that will transmit the position of the switches at any given time. This module will have to have the yellow wire from each switch connected to it...the signal that lights the green/red LEDs on the controller.
