I am using a SN65hvd233 and it has 60 ohm termination across CANH/CANL. When I transmit into the device I would expect data on pin4 (R) of this part. However, I am not seeing anything on the scope. Any ideas on what I am missing or how to better debug this?
FYI, I've tried normal and extended frame - changing the bitrate from 100kbs to 50kbs. I've added a common ground (even though this shouldn't be needed).
