ARRI CUB-1 LCUBE Miniature Signal Converter

The ARRI CUB-1 LCUBE Miniature Signal Converter converts LBUS protocols to serial protocols and vice versa. The UDM-1 can be connected to the ALEXA Mini via the LCUBE and a daisy chain of one or more cforce motors, delivering distance readings to the WCU-4, allowing focus tracking in the same way as is possible with other ALEXA cameras or the UMC-4 Universal Motor Controller.

Connecting the UDM-1 to the ALEXA Mini is just the first production advantage of the LCUBE. In future it will support various other serial protocols, permitting the latest ARRI ECS accessories to communicate with third-party cameras. 

Software Update:

ARRI has released Software Update Package (SUP) 2.0.2 for the LCUBE CUB-1. This release adds 3rd-party camera compatibility for the Master Grips, corrects a bug related to rounding issues of distance readouts with UDM-1 or Cine Tape Measure, and improves the general LBUS system performance. It also corrects an issue with imperial distance readouts on WCU-4 that slipped through in the previous SUP 2.0.1 release.

NOTE: ARRI highly recommends updating the LCUBE CUB-1 to this Software Update Package. Devices delivered from ARRI Austria from now onwards include SUP 2.0.2 (until superseded by future updates). This SUP adds the following new features and changes:

• 3rd-party camera compatibility for Master Grips
  
  • The LCUBE CUB-1 is a miniature signal converter that converts LBUS protocols to serial protocols and vice versa
  • This Software Update Package adds 3rd-party camera compatibility for the Master Grips, in particular REC start/stop functionality for Sony F5/F55, RED EPIC/DRAGON cameras and cameras using the LANC protocol (e.g. Canon, Blackmagic), as well as user button functionalities for RED Epic/Dragon cameras
  • NOTE: One of the following cables is required to connect CUB-1 with the respective cameras:
    • Cable CUB-1 to F5/55 Cameras (K2.0012631)
    • Cable CUB-1 to RED Cameras (K2.0012632)
    • Cable CUB-1 to LANC (K2.0012633)
• Bug Fixes:
  • This Software Update Package partly fixes an issue where distance readouts on UDM-1 or Cine Tape Measure displays would slightly differ from the WCU-4 readout due to rounding issues (the complete fix requires a software update for the WCU-4 as well, to be released soon)
  • This Software Update Package fixes a bug from the previous release version 2.0.1, where imperial distance readouts are not displayed on the WCU-4 handset
• Known Issues:
  • The LCUBE CUB-1 status LED indicates solid green instead of alternating green/red if connected to an LBUS device while no serial source is connected
