Network nodes
with gateway WTX16.GSM
WTX16.IP
WTX16.MOD-1
The WT…16… network nodes are used to receive and handle the data transmitted by
consumption meters of the Q AMR system. They are equipped with a gateway that
can provide data of up to 2,000 meters for remote readout. WTX16.IP can be read via
Ethernet while WTX16.GSM and WTX16.MOD-1 contain a GSM modem. They are read
via the telephone network.
Use
The WT…16… network node is a component of the Q AMR system. It has been designed
for use in buildings to create a radio network for receiving and storing the data transmitted
by the consumption meters installed in the building. Communication between several net-
work nodes is via radio also so that no wiring is required. All measured values acquired by
the consumption meters are continuously exchanged within the network, which means that
every network node stores the current consumption values, the values read out at the end of
the month, and the set day values of all metering devices on the network. Owing to this
operating principle, all network data can be read out at any of the nodes, or a QUNDIS gate-
way for remote data transmission can be used with any of the nodes.

*) The use of the GPRS application requires certain provisions by the network operator. To
use the GPRS option the user has to conclude a special contract with the service pro-
vider.
**) WTX16.MOD-1 has no M-Bus master. It cannot be used to interconnect different net-
works.
Combinations
All network nodes with gateway can be used in any combination with other QUNDIS network
nodes as long as the maximum number of 12 nodes per network is not exceeded.
Network nodes with gateway and integrated M-Bus master (WTX16.GSM and WTX16.IP)
can read external M-Bus meters complying EN1434/3.

The WT…16… consists of the following blocks:
transceiver for
Q AMR network
M-Bus
Master
5 unit loads
RS232
*) WTX16.GSM only **) WTX16.IP only
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.
***) user programmable
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).

The WT…16… consists of 2 major sections: The base and the housing with the electronics.
It is thus possible to mount the base prior to commissioning, enabling the electrical installer
to connect the WTX16 to the mains network. At the time of commissioning, the electronics
section is snapped on and the electrical connections are made.
The electronics section is identical for all types of network nodes. It contains control ele-
ments of the network:

If an unregistered IrDA-capable metering device (e.g.
WHE467) is connected in IrDA master mode, it can be
inserted into the network node by pressing the button
DISPLAY while ADD is displayed. The last 4 digits of device
number are indicated. (e.g. 20000123).
The registration of the device takes place and search mode
starts.
Delete (from
version 2.2)
for example
If an already registered IrDA-capable metering device is
connected in IrDA-master mode it can be removed from
the network node by pressing the button DISPLAY while
DEL is displayed. The last 4 digits of device number are
indicated (e.g. 20000123).
The removal of the device takes place and if necessary
search mode is stopped.

Connect the AC 230 V power supply line to the power pack of the WTX16… in the
following order: Remove the upper housing section of the WTX16… from the
base. For that purpose, remove the 2 cable connections (power supply (4) and M-
Bus (6)) between gateway and base. Then, use a suitable tool (screwdriver or
similar) to slightly open one of the two lateral fixing levers so that upper housing
section and base can be separated. Then, the top section of the WT…16 is to be
fitted using 2 dowels and screws (spacing of dowels is 184 mm with the
WTX16...).
Connection of the AC 230 V power line to the power pack of the WTX16... is to be made as
follows:
A 2-core mains cable (L and N) has to be preinstalled at the mounting site already. The
power pack must be connected by qualified staff. The cores must be sheathed with the en-
closed insulating sleeves to ensure compliance with safety class II. Then, the live (L) and
neutral (N) conductors must be connected to terminal “IN” of the power pack. Mains voltage
must be in the range from AC 100 to 240 V (50 / 60 Hz). There is no protective earth (PE)
connection. Then, cable strain relief must be provided by fitting cable ties.
Once the top section of the WTX16 is fitted, the housing with the electronics can be snapped
on. Then, the power supply connector can be plugged into the electronics section and the
WTT16 switched to installation mode by pressing the MODE button (red) for a few seconds.
Then, additional network nodes or consumption meters of the Q AMR system can automati-
cally configure themselves to form a network.
The standard baud rate of M-Bus master is 2400 Bd. To include 300 Bd M-Bus search it is
possible to switch this feature by parameterization software ACT21.
For updating M-bus device directory, there is an automatic search run for new connected
devices every 28 days. Devices, disconnected from M-bus, will be automatically deleted
from directory after 7 days.
After complete installation of all meters and network nodes, the gateway has to do a search
run to find all devices of network(s).
The search run started by triggering a command at the connected PC or by remote using the
software ACS26.

Connect the mains cable to
the power supply unit only!

SIM card
Network nodes WTX16.GSM and WTX16.MOD-1 require a SIM card and GSM- or GPRS
service contracts for voice- and data service. SIM cards, only sold for voice service or M2M
service, cannot be used.
For that purpose, remove the upper section of the WTX16.GSM from the base. Press the
SIM card slightly in the slot at the bottom of the gateway. Ensure that the chamfered corner
is in the correct position.
