Re: cRio Serial to Can Bus Troubleshooting

*** Update ***

1) We reimaged the cRio with the none option for the CAN bus and the net console box ticked with java as the language option.

2) Then we commented out all the code that dealt with the black jaguar can bus.

3) Uploaded code to robot.

4) Flipped the console out switch on the cRio (8 slot with physical dip switches).

5) Hooked null modem cable up to cRio serial port and computer. (After no console messages I double checked by doing a continuity check on pin 2 on one side and pin 3 on the other and vice versa.)

6) On computer opened putty, configured for serial, tried both com1 and com3 on different instances @ 115,200.

7) Powered cRio and watched for console information.

We could not get any console information through the serial port. I am pretty sure the port is dead.
