Bluebolt TCP IP Ethernet Card

well this is John Renault leave real-time automation today I'd like to talk to you about tcp/ip stacks I've been getting a lot of questions from customers about what a tcp/ip stack is one you know where do I get one how can i how do I use it and why I can't transfer it from one piece of equipment to another piece of equipment so let's get some background first what is Ethernet Ethernet is you know a wire the devices move a message from one place to another that's all it does to do that you need to have it at the hardware level we need to have a Phi a Phi is a special chip that takes in the voltages bits that are at the voltages of the computer and puts out bits that are at the voltages of Ethernet so this wire is you know a cap v wire or you know whatever whatever it is some some kind of you know it could be a bit various kinds of electrical interface electrical yeah electrical signals
