From the Tech.me website, it looks like they are selling a "converter box" that would allow you to connect the solid-state cells to existing computers such as Shearwater. The cells, being digital, likely need DC current supplied to function. Standard O2 cells are actually tiny fuel cell batteries and generate current of their own. The tech.me box likely has a lithium battery to supply the cells and a circuit board that converts the cell's digital output to the typical analog voltage ranges output by standard O2 cells. This would enable Shearwater to function normally.
And this is spot on - that extra box both supplies the power to the cells as well as converts the digital signal to analog, and then any electronics, like DiveSoft or Shearwater, can read it as it receives the very same signal as it would have when using "analog" cells.
And you literally plug the computer there directly.
You can also use the above approach with the DiveCan interface, just then need an extra cable and possibly an extra hole, as computer cannot be plugged directly into the extra box, instead this need to be ran back to OBOE/SOLO. You can see the two mini-molex connectors where you plug the solid state in and two "normal" molex connectors, which you plug in in place of your analog cells, so the signal goes via this box and back into "regular" one. (Note that this also can be used for 4 Pin, depends on whether you have the additional "cable gland" thingie it seems)
But this is the part where Shearwater needs to actually do something (that is if i understand correctly....) - while one can use it as is, its kinda strange as digital signal is first converted to analog and then converted back to digital (as DiveCan is digital as opposed to 4 Pin). So would be great to get rid of all those converters and be able to have signal going straight from cells direct to the SOLO/OBOE board. That might require some re-design of the electronics (as in the connector part) but rest should be just firmware update i.e. just tell the darn thing what to do with those 0's and 1's, that's about it. Unless one could also integrate extra power needed in the existing boxes, then that would also eliminate the need for the extra box.
So let's see how long that one takes.....pinged Dive Rite about it months ago, they spoke with Shearwater apparently but radio silence since...
