Well, I think it is... still experimenting.
I have 2 options:
1. Drill the IFBOX on the 'clean' left side and insert the three SDI outs out of the Multiplexer - That would give me 2x3G SDI outs and 1 HD SDI out. I would also leave the original 2 HDSDI outs intact. BUT, I think I would have to leave the audio boards out and cover the XLR ins. But, the great thing about this setup is that it gives many more recorder options (backup) and also it gives outputs to the left where most of us place our recording monitors and so we avoid longer wires getting tangled and breaking off.
2. Bridge the 2 SDI ports already existing and put them through the Multiplexer and then re-route it to one of the existing HD-SDI outs to be used as 3G when sending 12bit 444. My intial tests tell me that the problem is that the multiplexer does not switch the signal automatically to HDSDI because it is supposed to process the 2 inputs into a 3g signal, but it does not discriminate when the camera sends the HDSDI out and tries to make the 422HD into 444 anyway and so the signal gets jammed . So I don't think it will work. Unless I use the HDSDI out from the Multiplexer and 1 of the 3G outs and send those to the already installed SDI outs, out of the IF BOX... POSSIBLE BEST OPTION
3. Actually there is 3. Just make on IF box for 3G and if you need HDSDI, you use the camera monitor outs. This is the easiest and will keep the XLR's working... I think.
All I need is a 12-14v power down to 5v - 6W - about $10 from amazon and and wire it to the inputs into the camera XLR. Alternatively, I could try to tap into the Input from the camera and use the LEMO... I am not totally convinced about either one, except fitting the small Power Down Transformer may require that I remove the 4 Pin XLR input into the IFBOX.
Any suggestions, guidance or previous tests would be greatly appreciated, so share them below...
Will update as I move along.
