ARRI Simplifies Wireless Camera and Lens Control With New Radio Modules
The ARRI ERM-2400 LCS is wireless system designed for control.
When it's impossible for an operator to get their hands on the camera, wireless control is a logical solution. ARRI unveils its new ERM-2400 LCS system which can control compatible tech with a LCS, LBUS, or EXT interface.
The ERM-2400 LCS operates on the 2.4 GHz frequency band allowing users to wirelessly control ARRI handheld devices like the WCU-4 or SXU-1. Offered as a set of two, either unit can act as the transmitter or receiver, so there's no need to worry about which one is which. Once plugged into the hand unit and the camera, the ERM-2400 LCS will pair automatically by finding the optimal frequency channel. If any interference occurs, the device will automatically select a new channel using its auto search feature.
The ERM-2400 LCS provides an operating range up to 1,000 meters (3,280 feet). Each pair is pre-configured and can be identified by a matching number code on the back of the device. If multiple systems are being used on set, my suggestion would to be further label them with different colored gaffers tape or markings so managing them is quick and easy.
Possible pairing solutions:
- ARRI WCU-4 or SXU-1 and ALEXA Plus
- ARRI WCU-4 or SXU-1 and ALEXA Mini
- ARRI WCU-4 or SXU-1 and ALEXA Mini LF
- ARRI WCU-4 or SXU-1 and Universal Motor Controller UMC-4
- ARRI Master Grip or Operator Control Unit OCU-1 and cforce motor
- ARRI Digital Wheels DRW-1 and Digital Encoder Head DEH-1
- cmotion cPRO hand unit and cforce motor
The ERM-2400 LCS is designed as a lens control system. ARRI also has the ERM-2400 which controls stabilizing remote heads like the SRH-3. The original ERM-2400 is available in either 2.4 GHz or 900 MHz frequency band. Though the two product share similar names, they offer completely different functionality. So when inquiring, be sure to identify the preferred control system.
The ERM-2400 LCS set includes two radio modules, antennas for LCS, LBUS, and EXT, adapter cables, and a D-Tap power cable. There isn't a direct product page from ARRI yet, but cinematographer Greg Fraser is using it on the new Batman film from director Matt Reeves, so it's sounds like they're getting battle tested.
