Spektrum telemetry receiver

[Skye]

I have just purchased a Spektrum DX3S and am not sure which ports I can use. The throttle and steering are self explanatory, but then there is Bind, Auxillary, then Lap, Temp and RPM for the telemetry.

Ignoring the telemetry for a moment, I have my PT and power cap to plug in. One can go in the Aux port, but can the bind port be used for the other? If so, then does it matter which one goes in which port? If I can't use the Bind port for either the PT or Power Cap then what do I do? It says not to use the telemetry ports as it will cause damage so they are out of the question....
