The Windows-Based Auto-Discovery Manager
The Auto-Discovery Manager is a mechanism for remotely monitoring the Universal IP functioning. It also provides
support for configuring several key parameters, such as DHCP Status (enable/disable), IP Address, and the Host
Name of an MT100SEM-IP.
The Auto-Discovery mechanism is utilized by running a Windows-based Server Application that can
monitor/configure the MT100SEM-IP. Communication between the MT100SEM-IP and the Windows-based Server is
through MAC level broadcasts on a configured UDP port.
Two Ways to Use Auto Discovery: Auto-Discovery can be performed by using AT Commands (see the Universal
IP AT Commands Reference Guide – included on the Universal Kit CD) or by using the Auto-Discover Manager
Software (also included on the Universal Kit CD).
Auto-Discovery Manager Software
The Auto-Discovery Manager is composed of two components:
• The Client Component – The Client component periodically broadcasts its current configuration over
the network.
• The Server Component – The Server component receives the broadcasts from the client.
Client Component
The Auto-Discovery Client component is integrated with MT100SEM-IP. It broadcasts its current configuration
over the network on a specific UDP SERVER-PORT. By default the SERVER-PORT is set to 1020. The
configuration parameters broadcast are
• Version details
• MAC Address
• Static IP Address
• DHCP Status
• DHCP Assigned IP Address
• Host Name
• Broadcast interval
• Port number on which the client listens
Auto-Discovery Manager Software – Server Component
The server component provides server side support software for the remote user. It listens on the SERVER-
PORT and receives the broadcasts from the client and updates the list of configuration parameters. This list can
be viewed through the User Interface:
