GS1900-8 web configuration

Hi @RonHal, 

Make sure your PC's IP address is in the same subnet as GS1900(EX: 192.168.1.100).
Furthermore, if your PC IP address is correct, but still cannot access GS1900, please make sure IP of GS1900 is default IP. You can press reset button on front panel to make it return to factory default. Then you should be fine to login with default IP address 192.168.1.1.  

By the way, if you have question in the future, you can try to go to

I found there are many people discussing GS1900.
