You can connect everything together via a single S-Bus port on the receiver.

The S-Bus2 port is where you plug in the telemetry. You would use S-Bus2 servos, only, when connected to the S-Bus2 port. S-Bus2 servos, however, will work on the S-Bus and regular analog servo pins. When you connect the S-Bus2 servos to the regular S-Bus port, you may have to reassign them to the different channels, but the S-Bus2 servos should work on the S-Bus port.
