Can someone tell me if the PMU24 has a built in termination resistor on CAN 1? The diagram shows essentially two resistors in the wiring but no mention if there’s one built into the unit on CAN1

You can find this information in a pinout document:

We will add this information to the manual—thank you for the heads-up.

_Edit: information added to both PMU and ADU manuals._
