To change the IP address of this device, enter the address, subnet mask, and gateway, then click "Change IP". Set the IP address to 255.255.255.255 to specify that DHCP should be used to obtain an IP address upon power-up. IP address change will take effect upon next power cycle (or when Restart is clicked on the Config File page). The "Refresh" button only updates the information shown on this page, it does not submit a DHCP renewal request. DHCP renewal is automatic.

The numbers shown to the right of input windows are the actual numbers in the system. For example, entering an IP address of 255.255.255.255 causes the system to acquire a dynamic IP address via DHCP. The IP address shown to the right is the currently leased IP address. When DHCP is used, static DNS entries are ignored, and the actual DNS entries provided by DHCP are shown.

The default port for web page serving is 80. If you wish to change it, enter the port number and click Set Port. This change will take effect upon the next power-up. If the port is anything other than 80, you must include the port number in the URL. For example, if you would normally use http://10.0.0.101/ to get here and you change the port to 8215, you would now use http://10.0.0.101:8215/. You cannot disable the web port. If set HTTP to port 0, it will revert back to HTTP port 80. (Note: The port change is accepted only if you are logged in as the root user.)

Domain name lookup will be required if using the HTTP Client Update. If domain names are used, you must supply the IP address of at least one DNS server here. The DNS server must be at a static IP address. These changes take effect immediately. Note: If you are using DHCP, the DNS addresses will be supplied by the DHCP server and should be set to 0.0.0.0 here.

If the device is functioning as an HTTP client behind a proxy server, enter the proxy host name or IP address and its HTTP port in the proxy entries. Set the proxy port to zero to indicate no proxy is being used.

Client update requires a special server. HTTP Client Update is a method of reporting data from a remote site with no on-site configuration other than obtaining Internet access. Contact Control Solutions (support@csimn.com) for information about server requirements for using this feature.
