Here is the reason. When I bought the DNxIO I also purchase a HIB card just in case my card was problematic. I was pretty much told that it would work with my existing card and in fact it did and I've never had a problem or reason to switch to the new card.
I routinely have to switch between my NitrisDX and the DNxIO to maintain compatiblilty with work systems I work on. There is an issue as to how Avid processes Safe Color Limit effect when using Avid hardware and 3rd party hardware. It's the 0IRE vs. 7.5IRE confusion that happens. Even though the DNxIO is Avid branded it still behaves like 3rd party hardware in this regard. It's annoying when I bring a 4K project home that has been done on NitrisDX system and I run the DNxIO and all the safe color limiter effect then jump the black level 7.5IRE units washing out the image. So in those cases I hook up to the NitrisDX.
Today I am in exactly the position I anticipated where I'm going to have to farm out my DNxIO to my work system for a short while but still be able to work at home on other projects. So I will need my existing HBI and the new one on the farmed out system.
Once this is over perhaps I will consider putting the newer HIB into my home system now that I've heard that there may be issues. Until today all I had heard was if you plug it in and it works then everything is fine and no reason to swap to the new card. Today's information has opened that up for reconsideration. Gotta love the shared information on the L2.
The most important thing I've learned is I can take my new HIB to the work system and still run it's older NitrisDX. This will allow me to do a faster swap when the time comes to monitor 4K in that bay in a week or so. Nothing like format, monitor, color space, raster size, componet compatibliity, OS version etc... challenges at every step of the way.

I do have a HIB that came with my DNxIO purchase back in 2015 when they had the deal to trade in an AJA IO Express for a price break. To your knowledge does this problem potentially exist in a mac based system.

When Desktop Video 10.7 or later are installed in a Windows system with the HBA card with Avid part number 7030-30048-01, your system may experience hangs. Systems with newer HBA cards are unaffected. Therefore, Avid does not recommend installing the Desktop Video 10.7 or 10.8 software on a system with this card until the issue is resolved. Avid and Blackmagic Design are actively working to resolve this issue.BG

Subject: [Avid-L2] Re: Will DNxIO connect using an existing PCIe HBA from older NitrisDX?
Following up on this thread regarding older Host Bus Adapter Cards from a circa 2009 NitrisDX Purchase. I'm assuming as Dom pointed out in this thread originally that the older HBA card is probably of the passive V1 variety.
If I were to just shot gun this and plug my DNxIO into this older HBA is there any chance of damage to any of the components or is it just a matter of no communications?
I do own a spare HBA card that came with the DNxIO so I can swap out the older card but I'm also concerned if the newer Active V2 or V3 card that I have will still talk to the older Nitris DX unit at work.
On my home system the HBA for my NitrisDX that I purchased in 2012 works with my DNxIO. Does this mean that if I put my spare HBA into my work computer it will still work with the 2009 NitrisDX. Basically I'm asking if the newer PCIE HBA cards are backward compatible.

That is like pulling a Decklink card out of the PCIe slot while the computer is on. You must shut down before you move the cable to or from the DNXIO.AFAIK, if you use the 2 older HIB cards, DNXIO is not detected correctly by the OS and/or Media Composer.I have no experience or knowledge regarding the HIB card with the DNXIO. If the part number is the same, I assume it would work.Dom Q. SilverioOn Wed, Sep 21, 2016 at 8:24 PM, bigfish@... [Avid-L2] <Avid-L2@yahoogroups.com> wrote:
I'm going to check the model number on the HBA or is it HIB at work. I would guess given it came from 2009 era it will be an older HIB that is either passive of active Ver. 1. Is there any harm in just plugging it in to see if it works. Would the older HIBs somehow damage the DNxIO? Also if the work HIB is the older model if we get a new one compatible with the DNxIO would it still work with the older NitrisDX bob. I would like to have the ability to just switch the PCI3 cable between IO boxes in case I need universal mastering and any other feature that I might lose with the DNxIO.

However, the manual for the BM version just says:
"You can either purchase the UltraStudio 4K Extreme PCIe Cable Kit or you can use 'off the shelf' cards and cables from other manufacturers. PCIe is a universal standard for computer expansion cards so any adapter cards will work with UltraStudio 4K Extreme. To install a PCIe adapter card:"
