Modem Init String
The initialization string used by the U8/16-IP to initialize the modem. The default value will
work with all modern standard modems directly connected to a telephone line. In case you
have a special modem or the modem is connected to a local telephone switch that requires
a special dial sequence in order to establish a connection to the public telephone network,
you can change this setting by entering a new string. Refer to your modem’s manual about
the AT command syntax.
Modem server IP address
This IP address will be assigned to the U8/16-IP during the PPP handshake. Since it is a
point-to-point IP connection virtually every IP address is possible but you must make sure, it
is not interfering with the IP settings of the U8/16-IP and your console computer. The default
value will work in most cases.
Modem client IP address
This IP address will be assigned to your console computer during the PPP handshake.
Since it is a point-to-point IP connection virtually every IP address is possible but you must
make sure, it is not interfering with the IP settings of the U8/16-IP switch and your console
computer. The default value will work in most cases.
Pass-through access to serial port via Telnet
Using this option, it is possible to connect an arbitrary device to the serial port and access it
(assuming it provides terminal support) via Telnet. Select the appropriate options for the serial
port and use the Telnet Console, or a standard Telnet client to connect to the U8/16-IP.

Date And Time
Here you can set the internal real-time clock of the U8/16-IP. You can adjust the clock manually
or use an NTP timeserver. Without a timeserver your time setting will be lost if the U8/16-IP is
powered down for more than a few minutes. To avoid this, you can use an NTP timeserver
which sets up the internal clock automatically to the current UTC time. Because the NTP server
time is always UTC, there is a setting that allows you to set up a static offset to get your local
time.
Note:
The U8/16-IP does not adjust to daylight saving time automatically. So you have to set
up the UTC offset according to the local conventions of your country.
