Multiple ETH8020 relay board in a network

[sjaaaf]

Hello

I have a ETH8020 relay board ( 3 in total ) with I use in my company

I use a visual studio program to control the board. In fact I use the DEMO software from your website
in this DEMO program I made some visual adjustments to fit my needs and this is working very good
but now it works so well I need to control to boards with this program and that I can't get to work.

I did give 2 boards a fixed IP address, when I use 2 browser screen to log on to the 2 board it work and I can control the 2 board perfectly.

But when I use my program or the DEMO program with 2 board connected the program will show NO boards in the drop down box???
I tried to change the software coding but I don't that much experience in programming that I con get it to work.

Is there any way you can help my with this problem, I now have 3 boards in total and I really need them to word from within one program.

Any help is welcome
