The following parameters can be configured:
Note: The parameters must be adapted to the deployed
radio receiver.
1. Radio mode and encryption (security profile acc. OMS) [1]
• Select the radio mode: C1 or T1.
• Select the encryption: “None” or “OMS security profile A
(mode 5)” or “…B (mode 7)” (higher security).
Note: In Germany, encryption according to the OMS
security profile B (encryption mode 7) is necessary for
radio transmission to a smart meter gateway.
2. Data telegram [2]
• Select the required data telegram.
Note: If an encryption is selected for the data telegram,
the data telegram names are extended by the addition
“OMS-…”
3. Transmission interval [3]
• Set the transmission interval in 2-seconds steps.
The transmission interval can be set from a range of 16 sec-
onds to about 18 hours.
Example for 15 minutes: 15 x 60 = 900 seconds
Note: The update of the data between meter and the
radio module is always done in a fixed pattern. This
pattern is 10 seconds for mains supply and 15 minutes
for battery operation.
4. Telegram composition [4]
• The telegram composition can be selected individually
for the data telegram “wM-Bus / OMS – user-defined”.
Proceed as follows to compose the data telegram individually:
• Select the required values from the column “Available
values”.
• Transfer the required values in the column “Data Tele-
gram” by drag & drop.
The values not required can be transferred from the column
“Data Telegram” into the column “Available values” by drag &
drop.
Note: The frequency band allocation is automatically
checked. If the frequency band allocation is above
100%, the transmission interval or the telegram compo-
sition must be adjusted. The minimum transmission
interval is automatically displayed as a suggestion.
5. Age of Data [5]
The radio module retrieves data from the T550 calculator in a
time grid of 15 minutes. The transmission interval has a differ-
ent, parameterizable time grid. The "age of data" indicates the
time difference between the transmission and the fetching of
the data.
• Put a tick by “Age of Data”.
Note: In Germany, this option must be activated when
connected to a Smart Meter Gateway.
6.4 Apply settings
Proceed as follows to apply the settings:
• Click on the “OK” button.
After a successful parameterization, the following message
appears:
“OMS Parameters have been set.”
6.5 Leave parameterization
Proceed as follows to leave the parameterization operation:
• Click on the icon in the quick launch bar.
After a few seconds the following message appears:
“Meter is in Nb.”
The meter is now in normal operation (Nb-Mode) and the pa-
rameterization is completed.
6.6 Activating the radio module
Proceed as follows to activate the radio module:
• Press the button on the radio module for at least 2 sec-
onds.
The module immediately starts to send data telegrams accord-
ing to the selected parameterization.
The status and the radio mode of the radio module can be
checked in “Loop 4” on the meter.
Type “RF” in slot “Module 2” in 2 s. cycles
with one of the lower rows:
• For T550 (UH50…) FW ≥ 5.23:

• For T550 (UH50…) FW < 5.23 und T550 (UC50…):
Note: Each further press of the radio button triggers
the transmission of a data telegram with updated
data.
6.7 Deactivating the radio module
Radio deactivation by Service Software
Proceed as follows to deactivate the sending of data tele-
grams:
• In the menu bar, select the menu Parameterization → Ra-
dio module 868 MHz.
For T550 (UH50…) ≥ FW 5.23, the following window appears:
• Remove the tick from the option “Radio” [6].
Radio deactivation by Para-menu
Proceed as follows to deactivate the sending of data tele-
grams:
• Press the service button for at least 3 seconds until
appears on the LCD.
