Wireless control of multiple MDR follow focus units from a single Preston HU3 hand unit
16 years old. Gear and prices may have changed since.
DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- MDR1 units can be tuned to the same wireless channel to be controlled simultaneously from one hand unit because they function as receivers only
- MDR2 units are transceivers rather than simple receivers, making simultaneous dual control potentially problematic
- Preston offers firmware for MDR2 units designed to enable stereo setups that synchronize two MDR2 units with a single HU3 hand unit
- Using firmware-enabled stereo mode may face challenges when operating two cameras simultaneously that are not positioned side by side
- If only one camera operates at a time, switching off the MDR2 on the inactive camera allows standard setup to function without issues
Depends on
- The transceiver nature of MDR2 units creates technical uncertainties not present with MDR1 receivers
- Stereo firmware configuration was not confirmed as tested for the specific scenario of operating separate cameras on a dolly and motion control robot
- Practical viability of wireless dual control for non-adjacent camera positions remained unresolved in the discussion
