There is a new version of firmware and user manual for the 2CAN. Please visit: http://www.crosstheroadelectronics.com/2CAN.htm to download the latest. The LED states have been updated to help with troubleshooting and diagnostics. The user manual has been updated to reflect these changes. The CAN wiring diagrams have also been updated. There is also a new plugin for the cRIO. Both downloads are available in the ‘Downloads for FIRST’ section.
I see 2.0 but not 2.1 . . .
Also does this mess with sending raw frames?
There are two different verisons of the firmware. First and non-FIRST. You need to download the link under the ‘Downloads for FIRST section’

Sending raw frames should still be supported.
