I15007_en_02
If the signal LED is OFF, this generally indicates that the defined VPN connection is not
present. Either the VPN connection was not established or it has failed due to an error.
If the signal LED is illuminated, the VPN connection is present.
If the signal LED is flashing, the VPN connection is being established or released.
Analog line (for integrated modem)
WARNING: The analog connections (TIP, RING) should only be connected to the tele-
communications cable provided.
The TIP and RING contacts are for connection to the fixed-line telephone network (analog
connection).
For the contact designations specified on the front plate, the following designations are usu-
ally used in Germany:
TIP = a RING = b
ISDN line (with integrated ISDN terminal adapter)
WARNING: The ISDN connections (TX+, TX-, RX+, RX-) should only be connected to an
ISDN S0 bus.
Contacts TX+, TX-, RX+, and RX- are designed for connection to ISDN and identify the
mGuard industrial rs as a device in the ISDN network. The table below describes the as-
signment of the contacts to 8-pos. connections both for plugs and for sockets, for example
RJ45:

In the case of direct connection to an ISDN-NTBA, the mGuard connections must be estab-
lished as follows:
NTBA a1 -----> mGuard Pin 9 (Rx+)
NTBA a2 -----> mGuard Pin 7 (Tx+)
NTBA b1 -----> mGuard Pin 10 (Rx-)
NTBA b2 -----> mGuard Pin 8 (Tx-)
Serial port
WARNING: The serial interface (RJ12 socket) must not be connected directly to the tele-
communications connections. To connect a serial terminal or a modem, use a serial cable
with RJ12 plug. The maximum cable length of the serial cable is 30 m.
The serial port (serial interface) can be used as follows:
To configure the mGuard via the serial interface. There are two options:
