I recently bought the RVL PMS 2 because I managed to ruin my PMS 1. I'm using the old USB-C PD because I already had it and heard that they should work together. However, some of the connection names differ between the two versions, so I want to make sure I know what I should be connecting to what before I start trying things. Obviously stuff like BTN, CHRG, 5V and GND are self-explanatory. I would initially assume that the PD's SDA and SCL would go to the PMS's SD and SC, respectively, but I don't know that for sure. Are those correct? That leaves VSYS on the PD left to deal with. What should I connect to that? Also, is either PW or UP a 5V connection that I could connect to 5V on the PD? That one is mostly for simplicity's sake, to have all the connections to the PD on one side.
