USER GUIDE

Check interval - Interval for reporting again to the Dynamic DNS server by IP
Extender.
IP Extender has its own independent real time clock. Ensure the time setting is
correct by configuring a timeserver see page 30.
IP Extender registers itself to the Dynamic DNS server slightly different from the
time configured. To reduce load peaks on the server we add a random time (0-10
min) to the absolute time value.
70. Modem Settings
IP Extender has the option of remote access using a telephone line. Connect the
modem to IP Extender’s serial interface. Using a telephone line means building up a
dedicated point to point connection from your console computer to the IP Extender.
The IP Extender acts as an Internet Service Provider (ISP) to which you can dial in.
The connection is established using the Point-to-Point Protocol (PPP).
Before connecting to IP Extender, configure your console computer accordingly. For
instance on Windows based operating systems you can configure a dial-up network
connection, which defaults to the right settings like PPP. The modem settings are
part of serial settings panel (see the section above).
Enable modem on RS 232
Enable or disable the modem on the serial interface adapter of IP Extender. When
enabled, IP Extender tries to initialize the modem using an initial string of AT
commands and waits for incoming connections.
Serial line speed
The speed IP Extender communicates with the modem. Most modems today support
the default value of 115200 bps. Try lowering the speed of old modem if you are
having problems.
Modem Init String
The initialization string used by IP Extender to initialize the modem. The default
value works with all modern standard modems directly connected to a telephone
line. If you have a special modem or the modem is connected to a local telephone
switch that requires a special dial sequence to establish a connection to the public
telephone network, you can change this setting by giving a new string. Refer to the
modem’s manual about the AT command syntax.
