Key length
This is the length of the generated key in bits. 1024 Bits are supposed to be sufficient for most cases.
Longer keys may result in slower response time of the IP module during connection establishment.
3-4.5 Serial Port
The IP module Serial Settings allows you to specify what device is connected to the serial port and how to
use it.
Configuration or console login
Do not use the serial port for any special function, use it only for the initial configuration.
Modem
The IP module offers remote access using a telephone line in addition to the standard access over the
built-in Ethernet adapter. The modem needs to be connected to the serial interface of the IP module.
Logically, connecting to the IP module using a telephone line means nothing else than building up a
dedicated point-to-point connection from your console computer
to the IP module. In other words, the IP module 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 you connect to the IP module, make sure to
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 panel allows you to configure the remote access to the IP
module using a modem. The meaning of each parameter will be described below.
The modem settings are part of the serial settings panel.
Serial line speed
The speed the IP module is communicating with the modem. Most of all modems available today
will support the default value of 115200 bps. In case you are using an old modem and discovering
problems try to lower this speed.
Modem Init String
The initialization string used by the IP module 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
