E. Auto IP Report Protocol
OnCell Series provides several ways to configure Ethernet IP addresses. One of them is DHCP Client. When you
set up the OnCell to use DHCP Client to configure Ethernet IP addresses, it will automatically send a DHCP
request over the Ethernet to find the DHCP Server. And then the DHCP Server will send an available IP address
to the OnCell. The OnCell will use this IP address for a period of time after receiving it. But the OnCell will send
a DHCP request again to the DHCP Server. Once the DHCP Server realizes that this IP address is to be released
to other DHCP Client, the OnCell then will receive a different IP address. For this reason, users sometimes find
that the OnCell will use different IP addresses, not a fixed IP address.
In order to know what IP address the OnCell is using, you need to set up parameters in Network Settings via
Web browser. The figure below is the OnCell Web console configuration window. Enter the IP address and the
Port number of the PC that you want to send this information to.
ATTENTION
Search Utility and Driver Manager must be install
ed before using Auto IP report Format. Without Driver
Manager, the Auto IP port cannot be opened.
