Hi,
I have some vague questions about these devices:
- Is it easy to configure them, in general?
- The way to tell the device its IP number is through the serial interface?
- The protocol is connectionless?
- Which one is the cheapest you know of?
Thanks a lot.
Configure using web browser
They come preset to a specific IP address, and you can connect to this IP address to change it.
Usually three options - TCP Server, TCP Client or UDP. Once connection is established it is transparent. There are settings to control packetising - i.e. send packet after certain time out or if certain end of message character is recieved.
We use a product from moxa -
What if you forget it?
Also, according to what you say, it looks like I could not first set up and wire a network with several nodes and then assign IPs. Is this right?
More info please. What are you connecting it to. Have you already designed the circuit. Can you choose a processor to use with your circuit?
This is to connect around 100 monoliths at an airport, each one with a PC board and some extra electronics governing a turnstile that allows removing / inserting luggage carts inside a guide. The "extra electronics" has an RS-232 input, so the PC boards could hopefully be replaced by serial-to-ethernet adapters. The processor in the extra electronics was already chosen (designed and built). The one (if the converter actually uses one) in the serial-to-ethernet converter can be any one. That should be transparent to me. The goal is to minimize cost yet still allowing the same functionality.
