EAP-E
Once the IP address of the EAP-E is known it is possible to open a telnet session connecting to
the built-in ETRX2. By default the port connecting to the ETRX2 is port number 10001 as shown in
Figure 3. Please note that Figure 3 also shows a local command echo, which is why the characters
of the command ATI are repeated.
Figure 2: The Lantronix DeviceInstaller
The default Port number of 10001 can be changed to any port number in order to allow multiple
EAP-Es to be addressed via the internet. To do this the local router/firewall needs to be set up to
forward incoming ports to the respective port of the corresponding local EAP-Es. All you need now
to connect to your ZigBee® network via the internet is the remote IP address and the port number.
