Please pay attention to the consistency of the parameter data record; it is espe-
cially important to choose the correct modem.
Different procedures are necessary for commissioning the integrated RDT,
depending on the operating mode (dial-up line, GSM modem or TCP/IP net-
work).
Dial-up line
GSM
GSM wireless
modem
TCP/IP network
Dial-up Line:
1)
Remove the DSfG connector on the back of the
gas-net
device if a local
DSfG bus exists.
2)
Connect the modem and COM2 interface at the
gas-net
device using the
supplied V24 cable. Pull the telephone plug out of the TAE socket outlet.
3)
Switch the supply voltage of the
gas-net
device off and on again.
Switch 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
.
4)
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 representing the bus master, i.e.
which contains the entity with the EADR “_”.
Invoke the
DSfG
menu (
System
module) at the
gas-net
device, if this
hasn’t happened yet. You may view the station list here and compare it
with the planned bus configuration to check.

If an entity of the
gas-net
device is the bus master, initiate the general polling via the
operator panel at the device:
•
Switch to the main display of the
System
module.
•
Invoke the menu and select the subordinate menu item
DSfG
.
•
Press the Menu key again and confirm the subordinate menu item
General polling.
