9 Radio Readout
9.1. General Information about Radio Readout
The transmission of radio data depends on the technical specifications of the buildings and
their surroundings. Due to these external factors, a readout may not be possible at certain
times and in certain locations. It is solely incumbent on the user to check the radio propagation
conditions at the planned installation point.
9.1.1 Mobile Readout Radio Sontex (Sontex 566)
The heat cost allocator Sontex 566 is read out mobile with the radio modem Supercom 636.
The modem has a transmitting/receiving section and a radio antenna. The radio modem
operates on the frequency 433.82 MHz and is connected to a portable computer, a tablet PC or
a smartphone.
The software Tools Supercom features the following options:
Readout and display of an individual radio heat cost allocator.
Readout and display of a group of radio heat cost allocators.
Addition of devices in a router file.
Removal of devices in a router file.
Configuration of an individual or a group of heat cost allocators via radio.
9.1.2 Mobile Readout wM-Bus (Sontex 868)
The Wireless M-Bus radio communication interface enables data to be relayed using Wireless
M-Bus radio protocol (EN 13757-4) and complies with open metering system (OMS) specifica-
tions version V4.0.
The Sontex 868 uses one-way radio technology and transmits the consumption data and saved
settings every 120 seconds for short (OMS) or long (walk-by) telegrams.
Since the Sontex 868 radio heat cost allocator uses one-way radio technology, it must be used
with a Supercom 637 radio modem mobile data receiver and a laptop computer or touchscreen
tablet with the corresponding software program.
