Recieving CAN messages from External Source

Hello All,

I have an Arduino Uno and CAN shield (equipped with a MCP2515 chip) that I am using to listen to messages sent over a CAN network via PEAK PCAN interface. Messages are sent at 50 kbytes/s and ids range form 0x0-0x7ff.

I confirmed that CAN messages transmitted via Arduino /CAN shield are received via Arduino, but am unable to receive messages when transmitting only through PCAN. Therefore the issue appears to originate either from the PCAN-View software or the PCAN USB-to-CAN controller itself.

Where may lie the issue or how should I troubleshoot? Side note I did not bridge the 120 ohm resistor, however I didn't do this for the CAN shield and it still works fine. Thanks!
