There is a good manual on the 'Software > ExpertRemote system' tab explaining the set-up. If is very straight forward. Suggest you start by getting the Remote Server/Remote Client software set-up firstly before attempting to set up the separate Web browser version. You will need a PC to host the Remote Server software. This software will talk to the Radio using IP Address:Port Number. You can check these by opening the ExpertSDR2 software, Options > Device > SDR Address. Note the IP address and Port number. The trickiest bit is probably the Port Forwarding rules that you will need to set-up on your router. You will need 2 port forwarding rules. Assuming the radio port is 50001, then create a rule 50001-50003 TCP/UDP pointing to the IP address of the PC hosting the Remote Server software. Then another rule for port 5050, assuming you didn't change the default when the Remote server software was installed. This second rule also needs to point to the IP address of the PC hosting the Remote Server software. To be able to use the system from any location, you will need either a static external IP address on your router, or use a service to map the dynamic IP address assigned by your internet provider to a fixed domain name. The new v3 remote software doesn't need the static IP address.
