Ah, so you don't run DC and DCC models simultaneously. The WiFi throttle will just act as a DC throttle when running in DC mode. That's pretty handy.
Yes it is handy. How many DC only guys would love to have a wireless phone throttle or the ability to run a WiFi throttle they built or bought, like a TCS-UWT-50 or -100, for $75 to $150?
Use a DCC-EX command station and you have that for 2 blocks/power districts on your layout and can expand that to 4 or 8 blocks for not much more. Then (DC guys) would also have the ability to try DCC on one or both blocks at any time with a simple menu option on their throttle. No wiring change, no throwing an electrical switch.
The command station can simultaneously be sending DC to one block and DCC to another...
