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 register the Modbus Server will need to be enabled and a
Modbus Server address will need to be configured (See 3.15 - “Modbus I/O Transfer” for details on how this is done).
After enabling the Modbus Client you can then access the following information by reading the corresponding Modbus
Address at the Server ID address.
Note: ‘wi0’ is the normal default interface. If more interfaces are added by entering in virtual WDS
connections (either Client or AP) in section 3.17 - ”Repeaters (WDS)” then they will take on the next
available interface number i.e. wi1, wi2, etc

interface
5013
AP Only
Wireless Adaptor (wi0) - Points to the starting register of the AP's Station
List. First interface (wi0) will always start at 5200 and dynamically enter data
depending on the number of STA’s. Remaining interfaces (wi1-wi10) will be
entered after wi0 data. Register 5023, 5033, etc will indicate starting location
for each interface.
5014
STA Only
Wireless Adaptor (wi0) – RSSI & BGND of Rx message from AP e.g. Hex
5F5D = 5D for RSSI and 5F for BGND (Convert value from hex to dec and
add a “-“ e.g. 5F = -95dB)
