4. Address is the IP address of the router or device that connects your network devices to Wide Area Network or Internet It is a gate door that opens into WAN or another LAN When sending data to devices in WAN or Internet you need GATEWAY IP address to exit from Local Area Network Subnet Mask This should be same SUBNET MASK used in the LAN Check the Router s or Gateway s configuration to get the SUBNET MASK used Most LANs uses 255 255 255 0 for SUBNET MASK By this way 255 devices can be connected to one LAN If SUBNET MASK is 255 255 0 0 it means 255 255 65025 device can be connected to the same LAN If the Subnet Mask of the network and the device does not match then connection may not be established with that device Module IP This is the Local IP address of the module The IP number entered into this field should be unique in the LAN otherwise communicating with the device may not be possible IP address of the module should consistent with the LAN properties For example when the Gateway IP address is 192 168 1 1 and the subnet is 255 255 255 0 then the Module IP address must be within 192 168 1 2 192 168 1 255 Module Port This is the UDP port of the module is listening to Remote device will connect to this port If Ethernet Module is going to be accessed outside of the LAN and if there is a firewall or router in the LAN this port should be directed to Module IP address in the security virtual server settings of the Gatew
