Compatibility of follow focus systems with Alexa Plus built-in wireless receiver

14 years old. Gear and prices may have changed since.

What the thread found

  • The Alexa Plus built-in receiver and motor driver only works with C-motion and Arri Radio Follow Focus systems, not with Preston equipment.
  • C-motion cVolution handunits and camin receivers can be upgraded with a white radio module to become compatible with Alexa systems.
  • The white radio module signifies the frequency chip, and matching antenna colors between transmitter and receiver are required for proper operation.
  • C-motion equipment can be mixed and matched between cVolution, WCU-3, and wireless ZMU-3 units to control separate channels, with the first operator assigned to each channel.
  • Camera and LDS data display automatically on compatible C-motion handunits when connected to Alexa systems.
  • Upgrading C-motion equipment with the white radio module requires an investment that some users consider substantial.

Depends on

  • The discussion is from 2012 and technology may have evolved since then.
  • No Preston support exists as of the discussion date, despite past negotiation attempts between manufacturers.
  • Arri-provided follow focus kits sometimes had compatibility issues in real-world use.
  • The solution requires purchasing new or upgraded equipment rather than using existing Preston systems.
