It was required last year too.

Port 1 and Port 2 are on different networks. Both the deployment and the driver station packets need to be on the Port 1 network. You can use a camera or 2CAN or other Ethernet device on Port 2, just not the 2 functions you were trying.

Addressing the devices is a problem even with the BDC-COMM program. So it seems like wiring. We have gone through every possible combination of Jaguar, wire connection, and terminator. We've swapped all the different components (save the Jaguars) with parts from last years robot.
It seems like the serial to CAN translation is not occurring. The serial interface is working but the next device does not see any signal.

Make sure all your cables are straight through. Make sure you have 100 Ohm terminators installed. Make sure there aren't any shorts on the CAN bus (especially in the DB9 serial adapter).

Sure, if you have a scope or a differential DAQ system.
