Serial port
NOTE: The serial interface (RJ12 socket) must not be connected directly to telecommu-
nications 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:
– A PC is connected directly to the serial interface of the mGuard (via the serial interface
of the PC). The PC user can then use a terminal program to configure the mGuard via
the command line.
– Alternatively, a modem may be connected to the serial interface of the mGuard. This
modem is connected to the telephone network (fixed-line or GSM network). The user of
a remote PC, which is also connected to the telephone network by a modem, can then
establish a PPP (Point-to-Point Protocol) dial-up connection to the mGuard and config-
ure it via a web browser.
To manage data traffic via the serial interface instead of the WAN interface of the mGuard.
In this case, a modem should be connected to the serial interface.
