GSM Wireless Modem:
Important note:
Before starting with the commissioning of the integrated RDT,
make sure the accurate PIN number of the SIM card has been set in the
parameterization of the
gas-net
device (
Integrated RDT
module). The reason is
that the entry of a wrong PIN is only possible twice; if you enter the wrong num-
ber a third time, the SIM card will be deactivated.
GSM
1)
Remove the DSfG connector on the back of the
gas-net
device if a local
DSfG bus exists.
2)
Disconnect the wireless modem from the supply and pull the V24 cable off
the
gas-net
device.
Check whether the V24 cable is plugged in the modem. Test the antenna
installation (has the antenna been connected?).
Insert the chip card in the modem if you haven’t done it yet
.
3) Switch off the
gas-net
device and plug in the V24 cable at the
COM2
interface. Switch the GSM modem and
gas-net
device on again.
4) Change to the basic display of the
Integrated RDT
module. The current
status of the RDT is visible here. The device will try to initialize the modem
directly after start-up.
If the initialization fails, you will regularly receive
No modem
status mes-
sages between the individual initialization attempts. Check the modem set-
tings of your parameterization in this case.
Once the initialization has been successful, the status indication will
change from
Modem initialization
to
Basic status
.
If the status indication shows the text
RDT not in operation
, the SIM card
could not be recognized (for instance, because the card is defective or the
PIN is not parameterized correctly). In such a case, the integrated RDT
remains deactivated until the next start-up of the device will take place.
5) Check the modem’s data signal quality via the
Integrated RDT – GSM
menu (cf. description in Volume 1 under
Integrated RDT Module, Display
and Operation
).
6)
If there is a local DSfG bus, plug in the connector marked
DSfG
on the
back of the
gas-net
device. Perform a general polling at the device repre-
senting the bus master, i.e. which contains the entity with the EADR “_”.
Invoke the
DSfG
menu (
System
module) at the
gas-net
device. You can
view the station list here and compare it with the planned bus configuration

If an entity of the
gas-net
device is the master, please refer to Footnote 13, Page 8-

, for information on how to perform a general polling.
