Radio System 121
13.3 Radio System
A radio unit is incorporated into the ALEXA Plus module. This enables
wireless communication of lens control and lens data information as well as
remote control of basic camera functions.
Yellow radio
The ALEXA Plus can be equipped with yellow radio. This radio system has
also been in use with ARRI film cameras, so it is an interesting option for
rentals that already own equipment with yellow radio. Yellow radio can be
identified by a yellow ring at the antenna mount pont.
Note: Only a limited supply of yellow radio units is still available. Yellow radio is no
longer produced and approaches will no longer be available once all existing units
are sold.
