question
Can this be used between a Sony A7R2 (4K HDMI) and the older model Convergent Design 7Q (dual 3G-SDI)?
Yes, this can be used. Make sure it can accept Quadlink 4K.

Does this converter take a 4k input and output ...
Does this converter take a 4k input and output that 4k signal to 4 different hd signals (ie top left, bottom left, top right, bottom right)?
The AJA HA5-4K 4K HDMI to 4K SDI Mini-Converter does not support split-screening.

question
What does Dual link or Quad Link SDI Output mean? I want to use this with the Canon XC10 and send the 4K signal to a monitor with a single SDI input.
There are a few different strengths of SDI signal. The strength needed for 4k at 60fps is 12G-SDI. Some devices achieve 12G-SDI by having four 3G-SDI connections, which is what Quad Link SDI Output means and what this AJA unit offers. To achieve 4k at 30fps you need 6G-SDI, which some devices get by having two 3G-SDI connections, that is a Dual Link connection.To achieve this conversion with a single SDI cable you will need a device that converts to a single 12G-SDI output. The Blackmagic Design Teranex Mini HDMI to SDI 12G Converter is what you would need for this application.

question
Do you need HDMI 2.0 to be able to do 3840x2160 at 60 fps or this converter with HDMI 1.4 can do 3840x2160 at 60 fps ? I thought HDMI 1.4 maximum frame rate at 3840x2160 resolution was 30 fps.
You would need HDMI 2.0 for UHD at 60 fps, which this converter does support as well. So if you have a device that outputs HDMI 2.0, it will work with this converter.

question
I have 2 questions.Can this device AJA HA5-4K 4K HDMI to 4K SDI Mini-Converter - be powered on from the V-Mount battery with a P-Tap cable - that do P-Tap to Barrel power and what is the size of barrel 2,1 mm or 2,5mm?And the Second question is can I use this device with a Sony a7SII that do output thru Micro HDMI to HDMI cable (I am using that cable Atomos AtomFLEX HDMI (Type-A) Male to Micro-HDMI (Type-D) Male Coiled Cable B&H # ATOM4K60C2 ) that goes into HDMI input of this device and than from this device I need to use 2 6G-SDI cables that goes into Odyssey 7Q+ recorder that now supports 6G-SDI inputs (that was saying on the B&H site SDI inputs now support 6G-SDI in addition to 3G-SDI.) so I use two 6G-SDI cables that are coming out from the device to Odyssey recorder is that correct? So I can have 4K input and recording up to 60fps 4K?Am I right or I can't make it happen?
There is a P-Tap cable for this product, it is B&H # COXPAJA5. However the Sony A7SII only outputs UHD 4K at 30fps. This product will not change that, nor are we aware of any product that will allow you to get 60fps out of the A7SII.

I need to do a multicamera 4k UHD production with ...
I need to do a multicamera 4k UHD production with 4x Sony FS7. 4k output on FS7 is only via HDMI. I will be using Black Magic 4k Production Studio which has only SDI inputs. I assume I will need 4 of the Aja cards in the Open Gear Frame. Do the cards have HDMI inputs and SDI outputs? How can I achieve the foregoing using this set up?
Yes, this card has four 3G-SDI outputs and two HDMI 2.0 inputs. You would place these cards in the AJA openGear Rackmount Frame.

question
So I still have a question about quad link 3G-SDI.So if I need to receive the UHD signal (3840 x 2160) from HDMI output of my camera Sony a7SII to SDI I need to use four 3G-SDI cables (quad link 3G-SDI) but how I can input all four 3G-SDI cables into Convergent Design Odyssey 7Q+ (it's saying in specs that this recorder supports Single Link, Dual Link, Quad Link) if it has only 2 SDI inputs, can anyone explain me how quad link 3G-SDI is working?And what exact SDI cables I need to buy? Thank you?
The HA5-4K has a single HDMI 1.4 input, it does not have any SDI Inputs. Also, the 7Q+ can record 4K directly from HDMI. You would not need a converter to use the A7SII with the 7Q+.

question
Can this be used between Sony FS7 & FOR A - HVS 110 4 K switcher ? If so what is the maximum distance cable we can use for live switching ?
Sorry, can't help. I sent it back. I was using it between an X70 or A7s and Odyssey 7Q, and it got unreasonably hot in minutes.
