OK, I had a few minutes to try this, and had great success. I just added 120 ohms in a terminal strip between CAN-H and CAN-L wires.
I'm able to see some messages from the device now. Next steps will be to build up enough messages to be able to get the pressure from the device. There's a lot of ...

Re: Direct connection to DeviceNet device possible?
Thanks for the fast reply - It's almost definitely the cable. I didn't know there needed to be a termination resistor at all - I just blindly hooked up CAN-L and CAN-H signals. The device uses a 5 pin bayonet connector that also needs 24V for power, so I'm resorting to a custom cable.
I'll look at ...

Direct connection to DeviceNet device possible?
I've never done any DeviceNet communication before, but it seems that DeviceNet is built on top of CAN.
I thought that I'd be able to connect a DeviceNet device directly to a PCAN-USB and at least view some traffic. So far, I haven't been able to do that. I'm not able to see any communication from ...
