3: Configuring Modbus IAP Device Server's IP Address The IAP Device Server is shipped with a default IP address of 0.0.0.0, which automatically enables DHCP within the IAP Device Server. With a DHCP-enabled IAP Device Server, if there is a DHCP server to respond to IAP Device Server's request when it is booting up, the IAP Device Server will then get an IP address, a gateway address, and a subnet mask from the DHCP server. These addresses will not be shown in the IAP Device Server's Setup (configuration) screens (you will still see 0.0.0.0); however if you enter the Monitor Mode and from 0> prompt, type NC (upper case), the IP configuration of the IAP Device Server will display. .
