Confirmation of the Challenge Password
The email address of a contact person that is responsible for the U8/16-IP and its security.

Serial Port
The U8/16-IP Serial Settings allow 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 U8/16-IP 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 U8/16-IP.
Connecting to the U8/16-IP using a telephone line allows you to set up a dedicated point-to-
point connection from your console computer to the U8/16-IP. In other words, the U8/16-IP 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 U8/16-IP, make sure you
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 remote access to the U8/16-IP 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 U8/16-IP is communicating with the modem. Most 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.
