New to 2CAN and Jaguar

And I am also assuming the cRIO will communicate with the 2CAN using 10.xx.xx.10 as its IP address. What else did I miss?

The 2CAN acts as a gateway to CAN the cRIO simply passes the CAN frame over UDP, the 2CAN has no other interaction with the CRIO.

What you see in the web dash is the result of interactions between the 2CAN and the JAG's over CAN, this and the green led on the 2CAN means you are successfully communicating with the jaguars over CAN and you are successfully communication with the 2CAN plugin on the cRIO. Your problem is most likely in your code.

I noticed that you are calling the closed loop functions. If you are trying to just control the Jag in voltage control mode you do not need to to do this. Also I do not see where you init the Jaguars.

The functions used in CAN are the same regardless of the gateway used (serial or 2CAN). The only difference is the plugin. Make sure you have the most recent plugin and 2CAN firmware (version 2.18).

A couple questions:

1. What is the state of the Jaguar LED? blinking orange or solid orange.
2. What version of 2CAN firmware and plugin are you running?

The -44087 is a timeout error.
