Start a SimulationCRD300DA12E-XM3 Aux Port pinout
I'm trying to connect an encoder to the CRD300 and it appears the pinout for the Aux connector (J10), as specified in the CRD300 datasheet (rev B) and controller board schematic (rev 1.2), doesn't match the connector pinout according to its data sheet (and the numbers printed on the connector). After ohming out the whole connector it looks like what are labelled as even pins 2-26 on the schematic match the pins labelled 1-13 on the 3M connector datasheet (and odd pins 1-25 map to 14-26). Can someone confirm that I haven't lost my entire mind?
It looks like the mapping is correct if you follow the schematic symbol rather than the connector numbering, but if you are working off the XM3 datasheet as I did you'd never know that.

Hello jpl, the picture below shows the Aux. Connector (J10) pinout viewed from the top of the inverter. The numbers in black are the pinout from the controller schematic and the blue are from the 3M connector datasheet, so you will need to follow the schematic from Wolfspeed.
