Mark has prepared a presentation showing the essential steps in setting up telemetry with D-Series receivers. He concentrates on the FBVS-01 voltage monitoring sensor. The link is to his blog and includes a 4:41 minute video.
Taranis D-Series Telemetry: Lightning Version
- FBVS-01 is the voltage monitoring unit.
- The documentation is confusing. You don’t need to modify the default power options.
- FBVS-01 is supplied without connectors. Attach your own connectors as necessary.
- One end attaches to the D-Series Rx telemetry port. The other end attaches to your battery.
- Comes with a cable, attach it to the Rx.
- Only need to worry about the two left connectors, ground and positive.
- You can get rid of the other wires.
- Final connection: Battery — FBVS-01 — Rx
- Go the the Telemetry screen of your model setup menu.
- Set A1 Range to 13.30V. This monitors Rx voltage. You probably don’t care about this if you’re flying electric.
- Set A2 Range to 19.8V. We’ll cover why this is the right value later.
- Set the low and critical alarm values. For 3S, 10.5V and 10V are good.
- In the Special Function menu, set SF1: SB Down, Play Val, A2, 30
- When you flip switch B down, the current voltage will be announced every 30 seconds.
- When the voltage drops below the low and critical levels, you will get repeating announcements appropriately.
That’s all you need to get it working!
