I just read this article:
What is DiveCAN® and why should I care? - Shearwater Research
It says:
I want to put a NERD2 Monitor on my rEvo (which has a Predator DiveCAN controller w/rMS).
- The NERD2 Monitor cable that rEvo has appears to be a 4-pin DiveCAN connector on one end and 3 individual Molex connectors on the other end, which connect directly to individual O2 sensors. I thought the NERD2 Monitor was supposed to be digital. How can it be digital if its only input is the analog signals from the individual O2 sensors?
- rEvo sells a NERD2 Monitor for $2500 or so. Dive Gear Express sells NERD2 Monitors for $1750. If you order from DGX, you have to choose from JJ, O2ptima, or Prism2. But, the Shearwater article says those 3 and the rEvo are all interchangeable. So, what's the difference between them?
- if you order from DGX, why do you have to choose between those 3 instead of just having 1 choice that will work with any of those 3?
- will any of those 3 from DGX work with a rEvo?
- if one of them will work with a rEvo, does that mean it will work by connecting to the rEvo 4-pin cable that has 3 Molex connectors on the other end?
- I have a Shearwater Pursuit HUD on my rEvo now. Is it possible that the NERD2 Monitor would connect to the existing cable for the Pursuit?
I also have a Predator EXT on my rEvo. I am really just trying to figure out the most cost effective way to ditch the Predator EXT and the Pursuit HUD and have a NERD2 as my monitor - and without using a Fischer cable.
What would be really nice is a cable that goes from the O2 sensors to a black box like the Pursuit HUD has, and then a wireless feed of the O2 data from the black box to a NERD3 Monitor. I.e. a wireless DiveCAN Monitor bus. That would sure make it a lot nicer and easier to also use the same NERD3 when diving OC.
Thanks for any information you can provide!

It says:
a NERD, the new DiveCAN LED HUD, or a secondary Petrel DiveCAN handset can all be swapped freely and are generic among all manufacturers, except ISC who have their own connector and bus messaging. A common DiveCAN connector is being used by the rEvo, JJ, Hollis, SF2 and O2pitma, so monitor bus devices are compatible.
