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.

Thanks. Should UP be connected to 5V then, or should I just not have anything connected to UP?

Connect 5v to 5v. Do not use UP
