Dave, in Device Explorer, assign channels 16 and 17 to outputs ports 1 and 2 of your RX3. Power patch port 3 of RX3 (a Y from one of the CB200 servo outputs). Output 4 of RX3 goes to CB200 as usual.
Use low power demanding things as channels 16 and 17 connected to RX3.
That's the way I have it in some of my planes.
The important issue is the power patch !!! CB200 won't handle more than 200 mA from ports RX1 and RX2.
