The transmitter and the receiver are used to
collect data from the consumption meters and
to forward theses data to other nodes in the
network the data memory stores the consump-
tion data. It is protected against temporary
mains power failures by the backup battery.
The network nodes WTX16.GSM and
WTX16.IP are equipped with a gateway to
store data of up to 2000 meters and to provide
a possibility for remote readout via GSM or
Ethernet. The gateway has an additional M-
Bus master that can drive up to 5 additional
external M-Bus unit loads (e.g. up to 5 addi-
tional M-Bus meters). Usually, however, the
M-Bus master is used to connect nodes of
different networks to be able to read more
meters using only one gateway.
For extension of M-Bus, is it possible to con-
nect a repeater to the gateway.
The gateway can be programmed using an
additional RS232 interface.

The network node WTX16.MOD-1 is equipped
with a gateway for remote readout via GSM or
GPRS.
It has no M-Bus master, though. Therefore it
can read data from one network only (max.
500 meters).
