Ok, so to get telemetry to work with the DX3R you need the following items:
Receiver-
SR3000
SR3001
SR3300T
These are the ONLY Telemetry-compatible receivers

If You're using the SR3000 or SR3001 You will also need
SPM1325- On Board Module
The SR3300T has that integrated into it

From here you can pick up whatever sensors you'd like, or simply get the Nitro or Electric Telemetry Packs (SPM1300- Nitro, SPM1305- Electric). The telemetry pack will also include the SPM1325 on-board module and the sensors. It also comes with the hand held unit (SPM1320).

You may want to check out the video I did recently on how-to monitor the main battery pack voltage with the Spektrum Telemetry. It may help answer some of your questions as well.
