1. Safety information
Comply with ESD protection measures.
Avoid short-circuits on the PCB
Route connecting cables through the cable grommets
of the meter only.
Do not cut the grommets shorter than necessary
since this may lower the degree of protection.
Changes in the data telegram or the transmission
rate affect the battery life.
The meter sends no data telegram after delivery ex-
factory. The transmission starts after the installation
of the meter.
The module must not be plugged in during test-
ing / calibrating a meter on a test bench! For mount-
ing or removing the module, the 6-pole connector
shall be used for handling only!
2. Description of function
The radio module (firmware ≥4.69, see label on the rear side) is an
add-on module for the following types of meter: T550 (UH50…)
firmware ≥ 5.17 and T550 (UC50…).
Note: For meter of the type T550 (UH50…) firmware ≥
5.23, new functions are available (C1 mode, OMS
4.1.2 with security profile B).
The module enables the meter to communicate with a mobile
or stationary receiver using 868 MHz radio frequency.
The module supports OMS1- compliant data transmission.
The radio module is available in 2 different versions:
With integrated antenna (WZU-RF)
With external antenna (WZU-RF-EXT; cable length about
2,50 m)
1) Open Metering System Specification: Industry standard of a community of interest of
companies and associations. It develops open and vendor independent specifications for
communication interfaces and basic requirements for meters - http://oms-group.org
3. Installation and assembly
Up to 2 communication modules can be installed.

Note: You will find the permitted module combina-
tions in the respective Technical Description. The
radio functions depend on the T550 firmware.
Installing the communication module
The communication modules are connected via a 6-pole reac-
tion-free connector so that installation or replacement is possi-
ble at any time.
To install a communication module proceed as follows:
Press the 4 side lugs of the housing cover inwards and
remove the cover.
Put the communication module into the correct position.
Note: The module WZU-RF and WZU-RF-EXT may
be fitted at slot module 2 only.
Place the communication module carefully in both guide
slots and push it in.
To connect the antenna of WZU-RF-EXT, open one grom-
met matching the cross section of the antenna cable.
Note: Open the cable grommets in such a way that
they enclose the cable tightly.
Guide the antenna cable through the grommet from out-
side.
Plug the antenna cable to the module.
Note: When retrofitting a meter with radio module, the
voltage supply must be checked and, if necessary,
replaced. A battery type D or a power supply is re-
quired to operate a radio module.
4. OMS-compliant data output
The meter sends data telegrams acc. to the “open metering
system specification”:

6. Parameterization
The parameters for the radio operation such as
Radio mode,
Encryption,
Data telegram / telegram composition,
Transmission interval,
are pre-parameterized by the manufacturer. Adaption can be
done by using the service software UltraAssist.
Attention: Changes in the data telegram or the
transmission rate affect the battery life.
Note: Detailed information for the parameterization
with the service software can be found in the UltraAs-
sist user manual.
Note: Support for ordering can be found in the Tech-
nical Description.
6.1 Call up parameterization operation
To call up the parameterization mode, proceed as follows:
Hold the service button for about 3 seconds, until
appears on the LCD.
6.2 Starting the service software UltraAssist
To start the service software, proceed as follows:
Put the optical head on the optical interface.
Start the service software.
The service software starts automatically the status query.
After a few seconds the following message appears:
“Type T550 as UX50 (Version X. XX/ X.XX / flashversion) in Pb
(with calibration seal) found.”
If the service software is already started, just click on the
icon in the Quick launch bar.
6.3 Parameterization
To parameterize the radio module, proceed as follows:
Select the menu
ParameterizationRadio Module 868 MHz
The following window appears for T550 (UH50…) ≥FW 5.23. For
T550 (UH50) < FW 5.23 the new functions are not offered for
selection:
The following parameters can be configured:
Note: The parameters have to be adapted to the de-
ployed radio receiver.
1. Radio mode and encryption (security profile acc. OMS) [1]
Note: The module sends in T1 or C1 mode (unidirec-
tional) acc. to EN 13757-4.
Note: For data security, encryption acc. to OMS is
available: security profile A (Encryption Mode 5) or
security profile B (Encryption Mode 7).

Radio module WZU-RF, WZU-RF-EXT Subject to change 7
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.
