RIA-1 Radio Interface Adapter
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.
Depending on the transmitting power needed when using an RF-900 Radio Module with the RIA‑1, users can choose between Standard Mode, which transmits 100 mW, and Hi-Power Mode, which transmits 1 W. Hi-Power mode is recommended for long-range situations only.
Select Client Mode when hardwiring the RIA‑1 to a hand unit, OCU‑1/Master Grip, or cmotion’s steady/pan-bar zoom. Select Host Mode when hardwiring the RIA‑1 to a camera.
Yes, you can. This setup allows you to use the OCU‑1 remotely as an additional lens control unit with the ability to view lens data and control camera user button functions. A possible use case would be for the DIT’s iris adjustments, where the OCU‑1 can be mounted neatly near a monitor.
Yes, via the new Cable CAM (7p) to LCS (5p) (K2.0034580) which connects the CAM connector of the RIA‑1 to the LCS connector of ARRI ALEXA Plus type cameras. It provides camera REC start/stop, tally, camera settings, and status information via either the Hi‑5 hand unit or cmotion cPRO hand units (license required).
