I have an ADFWEB N2K/MB TCPIP interface that I need to program at some point for another project, and they do sell a CAN unit, but I was hoping for something native. We have tons of stuff on CAN, and even more of the devices that we read on stuff like MB TCP/IP is using a built-in bridge. HVAC is a good example. Currently using a Red Lion DSP, which I never would have spec'd myself due to price, but am enjoying using. Natively it's all CAN.
