4.8 Remote Configuration
Because a module configuration is viewed and changed in a Web format (which uses TCP/IP protocol), you
can view or change the configuration of a remote module via the wireless link, provided the remote module
already has a wireless link established to the local 245U-E. To perform a remote configuration, connect a PC
to the local module, run Internet Explorer and enter the IP address of the remote unit (or device name if
using DNS). The Configuration page of the remote module will appear and changes can be made.
NOTE Care must be taken if modifying the configuration of a module remotely. If the radio
configuration is changed, some changes made may cause loss of the radio link, and therefore loss
of the network connection.
It is advisable to determine the path of the links to the modules you wish to modify and draw a tree
diagram, if necessary. Modify the modules at the “leaf nodes” of your tree diagram. These will be the
furthest away from your connection point in terms of the number of radio or Ethernet links. In a simple
system, this usually means modifying the client modules first and the access point last.

4.9 Internal Diagnostics Modbus Registers
There are a number of internal diagnostic registers that can be accessed via Modbus TCP/RTU that will help
with analyzing and diagnosing the radio network. To access these registers, the Modbus server needs to be
enabled and a Modbus server address needs to be configured. For details, see “3.15 Modbus I/O Transfer.”
After enabling the Modbus client, you can access the following information by reading the corresponding
Modbus address at the server ID address.
NOTE The normal default interface is “wi0.” If additional interfaces are added by entering virtual
WDS connections (either client or access point) as described in “3.17 Repeaters (WDS),” they will
take on the next available interface number (wi1, wi2, and so on).
