A hub for the Hi-5 ecosystem

Capable of functioning as a receiver, transmitter, or motor controller, the RIA‑1 Radio Interface Adapter is a highly versatile component in the Hi‑5 ecosystem. Compact and robust, it supports ARRI's exchangeable radio modules and provides multiple connectors for wireless control of ARRI or third-party cameras and lenses.

Compatibility

Having worked with ARRI wireless focus systems almost exclusively for over 20 years, using SUP 2.0 for the Hi‑5 and RIA‑1 is a game-changer in terms of responsiveness, stability, Focusbug integration, and customization to my personal needs. A lot of thought and diligence went into the development, which shows at once. Thank you for making my life as a focus puller that much easier!

For me the greatest thing the RIA‑1 offers is flexibility and options. With the RIA‑1 I have been able to make the most of the RF-2400 modules in extremely busy RF environments where the standard radio modules would not have been able to perform as well. On top of this, I can utilize the RIA‑1 to create compact wireless solutions for any LBUS device, like the OCU‑1 or Master Grips. This has enabled extremely portable control setups for any axis controller.

The RIA‑1 is the perfect complement to the Hi‑5 platform. With the RIA‑1 I can use the RF-2400 Radio Module on the Hi‑5, which gives me improved connection at locations with difficult radio situations. Another bonus is the improved speed of the Cine RT because of the new high-speed protocol integrated into the RIA‑1, which makes it a powerful helper in certain situations, saving my bacon. The RIA‑1 is now a standard part of my working setup.

The ability to seamlessly integrate the Focusbug and its menu onto my Hi‑5 was only possible because of the RIA‑1!

The RIA‑1 is a fantastic device with huge possibilities. My favorite configuration is RIA‑1 together with OCU‑1. Thanks to this configuration DP or DIT can control the iris and functional buttons at the same time as I pull focus, which is very comfortable while working with crane or Steadicam.
