The node should stop if you get a VN:Permission denied message, so I don't think you would be getting any output data after that error. Can you copy paste the full log of the launch?

I don't think I'm getting any data to the node after the error either since the node is closed, it's more of I believe that the computer is getting IMU serial data at least. Here is the log launch:

Just to make sure, are you really connected to serial port 1 (pins 2 and 3) since the that port requires special cables to do the voltage level conversion from RS-232 levels to something that the USB can handle. Most likely you've connected the FTDI cable to pins 8 and 9 on the device, which are serial port 2. Do you get the error even if you set the binary_async_mode to 2?

Oh I had switched to the TTL and not changed the binary sync to 2! It works now! Thank you!
