The Vampire 500 V2+ accelerator card doesn’t provide network ports, but you can build an SDNet device, which connects to the micro sd and solves that handicap. ApolloOS includes all software you should need: sdnet driver and Roadshow TCP/IP stack. The version of Roadshow that comes with ApolloOS is a demo version. It works for a few minutes and then shuts down, but you can buy the full version if you want. You can find a more detailed tutorial on Github.
