2.7 Antenna connection
For proper operation of the communication module it is necessary to have
appropriate signal strength.
In places where the signal strength is strong it is possible to use internal antenna,
for areas with poor reception mount an external antenna (50 Ohm SMA-M
connected) to the antenna connector (6) of the device, which you can place inside
even inside the meter enclusre (under the plastic housing).
2.8 using the RJ12 connection
Connect the proper cable to the modem’s
RJ12 communication interface (11). The
listed registers can be readout on the cable (see Chapter 4).
The data is always active on the P1 interface, furthermore you can readout other
registers from the meters.
The RJ12 connection pinout can be seen in the following table.*
*The Pin nr. 2 inactvice in case of the relay
output version modem!
2.9 Relay connection
You can found the relay output (13)on the
modem’s optional
expansion. Then, by
using the Customer Interface, the client
can receive data in cyclic intervals from the
meter, which is switching the operation by
the current tarrif settings
–
due to the
modem’s
relay output switching.
