Powering a remote follow focus receiver on a Steadicam Flyer with limited power connectors
18 years old. Gear and prices may have changed since.
What the thread found
- A Steadicam sled with a single 2-pin Lemo power output can supply multiple devices if the connectors are wired in parallel, allowing both input and output functionality on the same connector.
- RF interference from a video transmitter can leak back through the power cable and block the follow focus receiver signal, requiring testing before production use.
- A Lemo splitter with one male 2-pin connector on one side and two female 2-pin connectors on the other side can be purchased as a molded part or fabricated from standard connectors.
- Follow focus receivers can be powered using XLR connectors as an alternative power distribution method.
- The Lemo connector commonly used for Steadicam sled power is described as size 0 type B two-pin.
Depends on
- The advice about parallel wiring applies specifically to BarTech follow focus units and may not apply to all follow focus models.
- Testing with actual transmitter RF output is necessary before field use due to potential signal blocking.
- The 20-year-old focus system mentioned uses D-sub and XLR connectors rather than Lemo, making it a different configuration.
- Specific Lemo part numbers and sourcing information is from a single recommendation and should be verified.
