Sony EVI D30, D31 + VISCA over RS232 - anyone got a predone scene?



  • I've relinquished an old Polycom video conferencing box of it's internal EVI D30 camera & it's currently hooked up to my Macbook Pro via a Prolific USB to Serial converter running as COM3 using Repleo drivers, with it's SVHS feed coming in via BlackMagic Intensity Shuttle. All is working perfectly, and I'm using the "Send Raw Serial Data" actor to send hex codes to the camera and it's all behaving as it should. Am just wondering if anyone's already got a scene set up with all the commands in etc to save me having to build from scratch?

    If not, I shall carry on and just build the whole thing...! *shrug*
    NB: it's MUCH easier getting it to work via Isadora than trying to get libVISCA to behave on OS X - original plan was to control via python-libVISCA from a web interface. Think now I'm just going to use OSC from my phone via Isadora instead. This appears to be the only satisfactory way to control an analogue PTZ camera from OS X, which I found vaguely surprising.
    See further down the thread for final patch files.


  • I had a patch that did this previously but it is on a drive that I can't access right now.... it was based on a patch I found on the old forum. 

    @Skulpture is the old forum still online, I can't find it?


  • @marci , i think it was this patch but can't verify it without a visca cam … 215694-canon_vc-c4_vc-c50i.izz.zip

    Yes I could remember that someone adapted my canon patch but I thought it was in the new forum so I could not find it. But HERE is the link to the thread in the old from where you (trukske) posted a patch for sony evi d70.

  • Ace - thanks muchly folks!!



  • Finally had chance to sit down today and look at both patches mentioned above... neither was a perfect fit, but @Michel - I loved your methodology for triggering the stops and allowing momentary buttons, so stole it. Anyways, managed to put together the below covering the majority of the D30 / D31 feature set - I've been picking these up dirt cheap off eBay recently, and via a cheap SVHS to USB stick with VideoGlide and a Black Magic Intensity and a few analog and digital matrix switchers I can now switch between 4 HDMI inputs and 4x SVHS Inputs, still with another 2 remaining for use within Isadora!

    Fully tested with a combination of Sony EVI D30 (NTSC) and D31P cameras, 4 total, wired via VISCA Daisy-Chain to RS232 via Repleo cheap USB>RS232 adapter on OS X Yosemite with latest Isadora.
    All pan / tilt / zoom / focus / white balance / speed options are handled at the moment. 
    In the future I _may_ add relative drive positioning for pan / tilt / zoom via a USB joystick x / y / z axis (or some variant thereof - have got a few Leo Bodnar boards kicking about and some spare sliders & pots).
    I **_WILL_ **be adding OSC to this and a Touch-OSC template in the very near future. (done)
    NB: Everything assumes serial port is 1\. Sorry. Will add a controller to the panel for this also. (done)
    New files added to post further down the page...

    Glad you could get at least a few hints from the other patches.

    Best Michel



  • As per the above, updated with control to choose Serial Port, OSC streams are now set up, and matching Touch-OSC template (for iPhone 5) 741814-evi-d30-d31-visca-over-rs232-control.izz aafebf-visca.touchosc.zip
