Premium Members Mark Schlicher Posted March 25, 2012 Premium Members Report Share Posted March 25, 2012 This was bantered about a bit earlier but it must be buried in a thread, and the search function won't unearth it for me. The question revolved around using the SD video line as a second HD-SDI line. Does it work, how marginal is it, etc.? I had a little time to test with my Marshall monitor, which has an SDI "signal strength" indicator. Pumping HD-SDI video down the HD-SDI line, jumpered from the sled to monitor with SDI-rated RG-179, the meter registered 90%. Sending HD-SDI video down the SD line, through the Hirose power/video connector supplied by Tiffen to the monitor, the meter registered 80%. Being curious, I partially disassebled the topstage and looked at the cables in the loom. Both connectors were wired with what appear to be the same type of RG-179 coax. So, a good robust HD-SDI signal from both connections. Quote Link to comment Share on other sites More sharing options...

I use the "SD" port exclusively on my rig as it cuts down on clutter. I even loop it through my monitor and out to a wireless transmitter sometimes. I haven't had any issues yet.
