What is/are your question(s)?

I’m working on setting up my opengenset Molex connector with my generic power pact with evolution 1.0 controller and want to make sure I’m understanding the pinout correct for end to end setup. Can someone double check my logic?

opengenset. Powerpact

Pin 1 (GND)————–Pin 2
Pin 2 (+5v)—————Pin 1
Pin 5 (RX)—————–Pin 8 (TX)
Pin 6 (TX)—————–Pin 7 (RX)

and those would be the only cables I’ll have connected since opengenset can run off +5v.

The pinout is on this page: https://github.com/jgyates/genmon/wiki/3.1--Making-a-Cable

I also replied to your contact request with the below information (I'm the main guy behind PintSize), but posting here for anyone who stumbles by later.

OpenGenSet can be powered by the 12v or 5v pins on the Molex or by the USB-C port. On OpenGenSet, HATs, pHATs, and the USB adapter the top two pins on the right are the data pins and the bottom row is 5v (usable by OGS and USB products), ground, 12v and the floating ground (not connected on OGS).

@jgyates can appendix R be deleted? There is no need for custom cabling as the PowerPact controller has the same pinout as the other supported Generacs.

I think so. I will do that later today.

[jgyates]

done.

Dropping some wiring pictures here incase someone needs help in the future, the standard cable from Pintsize would have worked but I removed unused cables and repinned due to looking at the diagrams incorrectly.
