Starting Sony DSR-50 and DSR-DU1 in record mode with a timer?

Discussion in 'Professional Video Production' started by Paolo Bellutta, Apr 29, 2004.

  1. I am assembling a system to automatically capture images from a
    camera. Since the environment where the system is installed will be
    pretty rough, I am planning to connect the camera to the DSR-50 and
    daisy chain the DSR-DU1 to it. Actually this is my system setup:

    Horita (GPS-based sync)
    GPS-MTG
    |
    |
    v composite IEEE1394
    camera --------> DSR-50 ---------> DSR-DU1
    ^
    |
    Horita ------------
    GPS-MSG

    (GPS-Based Time Code)

    What I want to accomplish is GPS-time code labeled images to tape and
    disk. This system needs to start recording automatically when a
    trigger event is received. The trigger event will provide power the
    the entire system but what I am getting concerned about is start of
    the recording on the two DSRs. Start of recording on the two devices
    does not need to be simultaneous, but I want to make sure record mode
    is started without having to press any buttons or configuring the
    devices.

    I never used these machines and tried to get some info from Sony and I
    have done my homework on google, but I have come out empty. I was
    thinking to try to interface on the 26-pin connector and use the
    camera trigger (which pins?) to start recording or use the foot switch
    connector on the DSR-50. But what about the DSR-DU1? I see that it
    is dockable, so I assume there is a way to start recording from camera
    as well, but could not find any info on this.

    Thank you for your time.

    The DU1 is designed to be triggered from the camcorder just like a VTR would
    be from the 26 pin connector or so Sony says. The connection between it and
    the camera, the firewire cable, carries the record trigger. I think it also
    has a pre-trigger recording capability of 8 seconds or so IIRC.
