Premium Members SergeiFranklin Posted March 17, 2007 Premium Members Report Share Posted March 17, 2007 I have been using a PRO system with TB-6 for about 6 years . I like my system but directly connecting multiple video devices causes incorrect termination. I had been using an external VDA with my recorder on my previous steadicam system and have used this till now. I have just purchased a chasecam.com PDR100-H and realized I needed to redesign the video system. There is room inside the battery module between the recorder and transmitter Lemo for a VDA from VAC model number 11-011-504 http://www.vac-brick.com/CompositeVideoDAD...oductFamily=MFB I attached the DA with Velcro. I replaced the recoder/playback switch with a DPDT version C&K T201SHZQE digikey part number CKN 1089-ND (radioshack's does not have the same thread pitch, so you need to order this) Now the recorder/playback switch is finally functional and my Modulus looks better. I mount my video transmitter on the bottom of the sled. With this modification you would always want the transmitter on the bottom. I have done this for years without any problems ( CIT antenna with Sony tuner). I cut the power to the 5 pin and power the recorder from the camera battery as powering from the video battery causes noise in the system. I think the XCS electronic level and PDR-100 on the same battery cause the noise. It can also be powered from internal batteries. I am still working on this with chasecam. I will report more on the PDR after I test it on a few jobs. So far it is a big improvement over my DV deck. Quote Link to comment Share on other sites More sharing options...
Premium Members Charles Papert Posted March 18, 2007 Premium Members Report Share Posted March 18, 2007 Does this solve the issue of recorders that have separate and simultaneous inputs and outputs causing a ghosting effect on the sled video (because the image is feeding back on itself)?

Yes it will as the VDA outputs are isolated. you would use the same wiring except that in and out go the same pin on the 5pin lemo. I used to use an external DA from VAC with a switch so the recorder is fed via the vda for record and direct for playback. Its a lot more elegant inside.
