March 11, 2011

This entry is part 3 of 11 in the series Lon over IP (709.1/852)

The CN/IP device is a more complex connector because is connects two different protocols and may also connect the protocols at different layers.

1.2 IP Tunneling

March 11, 2011

This entry is part 2 of 11 in the series Lon over IP (709.1/852)

The 852 protocol acts as the transport service to convey 709.1 messages over Internet Protocol (IP) networks, i.e. tunnel. As previously mentioned, in 852 parlance the tunneled protocol is a Component Network (CN) protocol. The 852 protocol is a generic tunneling protocol and is not limited to 709.1.

When the download is blocked nothing is transferred to the GR4 so nothing will be [...]
