3.2 Assigning the IP through the serial port
After the LAN-Modem has been reset, a time window of
approx. 1-2 seconds is provided during which you can
assign a new IP address by entering at least three „x“.

In contrast to the previously described using ARP,
this serial path works regardless of whether the
L A N - M o d e m a l r e a d y h a s a n I P a d d r e s s o r n o t . T h e
procedure can be repeated as often as desired. This
method is therefore recommended if you do not know the
IP address or have forgotten it.
First connect the serial port of the LAN-Modem to a
computer. For a standard PC or a laptop, you will require
a 1:1 modem cable (see section
2.2 The RS232 connection ).
The serial transmission parameters of the terminal program
used are configured for
9600 Baud, no Parity, 8 bits, 1 stop
bit, no handshake . Interrupt the supply voltage to the LAN-
Modem to perform a reset. If the green Status LED comes on,
enter the letter „x“ at least three times on the terminal until
the LAN-Modem has returned the prompt „IPno.+<Enter>:“.
Use the usual format (xxx.xxx.xxx.xxx) to enter the IP
address and finish your entry by pressing <
Enter >. If the

assigned IP address. Otherwise a „
FAIL “ message is
returned with the last current IP address.
All other settings such as the gateway address, subnet
mask, etc. are made using the Telnet configuration menu
(see section 3.5
Configuring the subnet mask and gateway ).
