  • Page 11: Speed Ramps

    The WRC-1 allows the camera speed to be changed while simultaneously retaining a constant exposure. Several different compensation methods can be selected.

  • Page 12: Functions

    A RUN LED is also integrated. In the CAM mode, the OPEN button on the WRC-1 serves as the PHASE button on the camera. In CAM mode the WRC-1 serves purely as a camera remote control unit, without any wider programming options.

  • Page 13: Wrc Mode

    Example: the WRC rotary switch is set to fps, the COMPEN- SATION rotary switch is set to Iris. The camera speed is adjusted with the handwheel, while the WRC-1 automatically keeps the film exposure constant, adjusting the iris of the lens.

    4. Setup 4.1 WRC-1 in wireless mode In order to be able to use the WRC-1 in wireless mode, it must be mounted on a Wireless Main Unit (WMU-1). The Wireless Main Unit supplies the WRC-1 with power and establishes the radio link with the camera.

  • Page 18: Mounting The Wrc-1 On The Wireless Main Unit (Wmu-1)

    Swing out the unit and then remove it by pulling it upwards. • With the wide black pin photo insert the WRC-1 into the free space on the Wireless Main Unit WMU-1. Then press the WRC-1 onto the WMU-1 until the module audibly snaps into position. Note: The WRC-1 cannot be mounted on a WMU-1 together with other modules.

  • Page 21 • Connect the CCU socket on the camera with the CCU socket on the UMC-1 using the UC-R1 cable. • Select the same radio channel on the UMC-1 as is set on the WMU-1 (see LCS Instruction Manual, photo chapter 5.1.2.1). If several lenses are to be remotely controlled independently of each other, the radio channels 0 and 5, 1 and 6, and 3 and 7 can not be used simultaneously.
