TECHNICAL DESCRIPTION
The RFM-TX2 radio module transmits
the data measured by the water meter
over which it has previously been
installed.
The radio transmission operates uni-
directionally, while the set-up data
communication is bi-directional.
The module can be mounted over every
size and version of our water
meter
s
GMDX-RFM
and GMDM-RFM.
The set-up data and the radio signal are
received
by
a receiving
module
connected to a PC using our proprietary
software the HYDROLINK.

receiver
and
the
HYDROLINK
software and then press the button
indicated by the arrow for the
module initialization. During the set-
up phase an LED will blink. For the
set-up instructions, please refer to
the software documentation.
Immediately after having set it-up,
install the module to the water
meter capsule. The 3 tongues
indicated by the letter A must plug
into the 3 slots indicated by the

Turn clockwise the RFM-TX2 module
until the module is blocked.
The module is now correctly
mounted and blocked.
NOTE: Please consider that there will
be 30 seconds to install the module
on the meter after having pressed
the button indicated by the arrow.
After this time the module removal
alarm
will
be
activated.
To disable it, a new set-up procedure
is required.
Two options are available to prevent
the fraudulent module removal:
1.to stick a self destroying security
label included in the package,
between the meter capsule side
edge and the module side edge.
2. to fit a metallic or plastic wire into
the hole indicated by number 2 and
then to seal it (seals and wire are not
included).
After the sealing, please make sure
the module is properly locked.
ATTENTION
The module is switched off at the
time of purchase. Once the module
has been initiated, it starts to
transmit and it can no longer be
turned off, but reconfigured only.
