So I have a coMputer with two ethernet ports. I use one to connect to the relay board and the other connects to a switch. For whatever reason when I type in the correct IP address for my board it does not open. If I unplug the ethernet cable connected to the switch then my board works. I wrote my own GUI using C#. Not sure why having two ethernet ports connected causes connectivity issue with my board. Is there something in my code I should be adding to prevent this?
Hi,
Network drivers aren’t generally designed to connect to two networks.
You can use software to create a bridge, although its dependent on the OS.
If you do this make sure you use a crossover cable and give the ethernet module a static IP address.
This is theoretical knowledge as these devices were intended for use on a managed network and we have not tested them in this particular configuration.
