7 Commission RF converters
Determine the best location for the RF converter. The RF converter can be
powered by an external battery (using its USB connection) to search for the
optimum location. Additional information is available in Section "Locating RF
converters", page 25.
Ensure that all RF converters belong to the same radio network.
Ensure that all RF converters have the same Mesh ID and same channel ID
within a radio network. You do not need to change the Mesh ID if the blue LED
flashes for more than five minutes. You must change the Mesh ID if the blue
LED is on continuously after just a few minutes. The RF converter is configured
with the ACT531 M-bus configuration and readout software, version ≥ 2.0, or
locally using the S1 and S2 buttons. Additional information on the M-bus
configuration and readout software is available in document A6V10844345. See
section "Reference documents", page 7.
The M-bus operation mode (C+T/S-Mode) must be the same for both the RF
converter and the meters on the radio network. Mount the RF converter on the
wall. Additional information on mounting is available in document A6V11135905.
See Section Reference documents, page 7.
7.1 Data security and encryption
The radio network system supports devices with AES128 encryption
7.2 Troubleshooting the RF converter
The RF converter does not switch on.
Ensure that the required operating voltage (AC 100...240 V) is connected.
Check the quality of the USB cable if using the USB connection or whether
the PC is able to supply a current of 500 mA.
The blue LED flashes.
Ensure that the web server is switched on and the antenna is connected
and oriented to receive radio signals.
Ensure that the distance between the web server and the RF converters is
at least 5 meters. The minimum distance between individual RF converters
is also 5 meters.
Use the ACT531 software to ensure that the mesh network ID and the
channel ID are correct and match the mesh network ID and channel ID of
the web server. Further information about changing the mesh ID and
channel ID is available in document A6V10844345. See section
"Reference documents", page 7.
