The Cine RT System

The Cine RT System is one of the most popular distance reference tools available to professional focus pullers, and the best ultrasonic cinema rangefinder & transmitter tracking system in its class.

Designed by camera assistants

Widely recognized for its operational flexibility and exceptional performance, the Cine RT satisfies a broad range of working methods on film and digital cameras.

Purpose built components

Our components are constructed from pro-grade materials and electronics rated to work within industrial operating temperature range - built to withstand a life on set.

Expansive toolset

The innovative distribution of ultrasonic transducers across the custom-built wireless component family enables an expansive toolset unique to the Cine RT.

LCS Integrations

Custom-designed and third-party serial protocol outputs deliver fast distance data to lens control systems by ARRI, Preston, c motion, Teradek, and Heden.

The System Package

The component family enables multiple working modes to display real-time subject measurements and facilitate the collection of focus marks. 

Ultrasonic Base Sensor

The lightweight, low-profile ULTRASONIC BASE SENSOR is the computational center of the Cine RT System and the only system component required on the camera, making it ideal for all camera builds.  

Handset Control Unit

The HANDSET CONTROL UNIT is both a remote command centre and a handheld tape measure. It contains a pressure-sensitive touchscreen to access system-wide operational settings and display multiple distance readout modes.

Multiple

Use multiple displays

High-Bright LED Display

The compact HIGH-BRIGHT LED DISPLAY receives data remotely from the BASE and relays distance information with ultra-bright LED numbers.

0
Use up to four bugs

Ultrasonic Bug Transmitter

The miniature ULTRASONIC BUG TRANSMITTER is milled from rugged ABS, weighs virtually nothing and can be easily hidden under most fabrics.

LCS Integration

The Cine RT System’s utility goes even further by connecting to all popular lens control systems. Custom or native serial protocols deliver fast distance data to products by ARRI, c motion, Preston, Teradek and Heden. In 2022 Focusbug’s partnership with ARRI advanced the integration to include the Focusbug License for bi-directional operational compatibility with the Hi-5 focus handset.

If your Cine RT Serial or Y Cable was purchased at the end of 2021 onward and has blue shrink wrap it is Bi-Directional and supports use of the Cine RT’s ARRI Hi-Speed Protocol Output.  If you have a cable purchased before Q4 2021 you can output ARRI Classic but will need a Bi-Directional Cable to use ARRI Hi-Speed.

A quick update regarding some additional announcements (and clarifications) regarding the Cine RT Hi-Speed Serial Output as related to the ARRI LCUBE SUP 3.0 firmware update.1.  cmotion cPro and cPro Plus users can now take advantage of the Cine RT’s ARRI Hi-Speed Serial Output for faster display of distance data and bi-directional control of some select Focusbug Cine RT settings such as FPO, Limits and Sensitivity!  A Bi-Directional Serial or Y Cable (blue) is required and can be purchased directly from Focusbug.2.  For the ARRI Hi-Speed Serial Output to be sent, a bi-directional handshake is required between the Cine RT and LCUBE.  This handshake is needed for use of the ARRI Focusbug License AND for the display of distance data on a Hi-5, WCU-4 or cPro.  Accordingly, a Bi-Directional Serial or Y Cable (blue) is required for all use-cases.3.  If you have an older Uni-Directional Cine RT Serial or Y (black) cable you can continue to use the ARRI Classic (or cPro) Serial Output; however, you will require a bi-directional cable to use ARRI Hi-Speed.  We apologize for any misinformation regarding this requirement.4.  Focusbug does not have an exchange program for older uni-directional cables.  These cables have not been sold since Q4 2021.  All cables sold since are bi-directional.  If you do not want to purchase a bi-directional cable and would prefer to have a local technician repurpose your uni-d cable connectors, you can purchase a Bi-Directional Serial or Y “Cable Body” from Focusbug for $150 USD (shipping not included). The cable body contains the required in-line electronics and flying leads which you can have cut to your preferred length.  Please be aware that Focusbug cannot provide a warranty for cables assembled by a third party.We hope this information provides some good news for c motion product users and serves to clarify the difference between bi-directional and uni-directional cable usage as pertaining to the Cine RT ARRI Hi-Speed Serial Output.
