Yeah, I'm not sure I'd use the term "older" for the NexStar + hand controllers with the serial/RJ connector (even though they are indeed older) ... we're now into latest, new, older, old, ancient, etc. hand controllers ... it's going to get confusing with the different terminology.
syscore - do you know if the Starsense hand controller is the same hardware as the NexStar+ ... "the same" aside from the label and the firmware of course?
There are a few trivial things that differ between my StarSense HC and Nexstar + HC, both purchased in 2016; and both RS232 (hence older); but I think these confuse rather than cause any real issues.
The newer USB port versions may differ as regards some functionality, but I know that ALL remain Serial inside despite having the USB port. For example, you still need a Windows 10 Serial Adapter DRIVER to update their firmware via that OS. But there are other differences....
For example, if you have added 10 (optional) 'additional alignment points' via Starsense you should not need 'SYNC' or 'Precise GoTo' which don't feature in its HC. The additional alignment points work like SYNC, but StarSense remembers ten (not one/last). If spread across ten constellations (better still across 12 months), you hence don't need these functions.
You also can't adjust the Evolution's tray and logo lights via the Serial/RS232 Starsense HC. But you can via SkySafari/WiFi (which most Evolution owners probably use). But it's no hardship to set them once only using the older (Nexstar +) HC. It is probably worth mentioning that the Starsense Serial/RS version HC did have a firmware upgrade in February 2016. Mine has performed better since that and the Evolution mount firmware update of August 2016. The Starsense camera firmware has not been updated in the last two years (if ever).
I believe that the newer USB HC + versions are a marginally different shape (don't fit old HC cradles) and have sculptured raised buttons (some reports of sticking due to poor QC). Frankly, I think we need to create a new descriptive convention. Such as Nexstar HC version xx; Nexstar + HC/RS; Nexstar + HC/USB etc. Else this will get ever more confusing. Referring to "old" and "new" no longer works.
