6 Configure the Operation Modes
Use the cursor keys to select the parameter you want to change. Hit <Enter> to edit them. Type
the new value, or select provided options. Use <Esc> to leave a parameter or menu. Please check
the configuration of your Telnet, if there are any problems.
6.1.3 Serial Configuration
In some situations it may be impossible to get network access to the NetCom
+
Device. If this hap-
pens (e.g. by an accidentally misconfiguration), neither Telnet, nor the web interface is functional.
It may be even impossible to use the NetCom
+
Manager program.
In this case you must connect to the NetCom
+
via the serial port. Disconnect any serial cable from
NetCom
+
. Set the DIP Switches to "RS 232 Configuration" (all switches to Off, section
3.1
). Then
connect the NetCom
+
with your computer using a Null Modem cable. If your NetCom
+
is an old
model with a connector DB9 female, attach the supplied Null-Modem Adapter to the port first. Or
connect your computer to the female connector with a straight-through cable.
Open any serial terminal program (Hyper Terminal, minicom, PuTTY
6
, . . . ), select 38400 bps,
8 Bit, No Parity as configuration. Set your terminal to emulate a VT100 (recommended, but VT52
is also possible), including the Arrow keys.
Then power on the NetCom
+
. When connected to NetCom
+
you must define the type of terminal
used (VT100 or VT52), and optionally provide the password. This is the same configuration option
as described above at
6.1.2
, so follow the instructions for Telnet.
When the configuration is done, change the DIP Switches back to normal operation. Later con-
figurations can be done by web interface or Telnet. Of course this requires to have a functional
IP configuration defined.
6.2 NetCom Configuration Options
Some of the menus are very long, especially on the web interface. These are divided in their
logical sections throughout this document. Each section shortly mentions the way to access the
parameters. Short screen shots show the typical display when configuring the NetCom
+
. Usually
the web interface is shown on top, and the terminal interface (Telnet, serial port) is shown below;
a horizontal line divides the two. On few occasions the two screen shots are displayed side by side,
with the web interface to the left and the terminal interface to the right; then divided by a vertical
bar.
6.2.1 Server Configuration
In your web browser click on the Icon of “SERVER CONFIGURATION”, the browser opens the
basic server information, the server parameters related to the IP-configuration, the parameters for
Wireless communication, the section for encrypted communication, Password settings, and finally
the configuration for date and time.
In Telnet the
ServerConfig
offers the IP parameters, Wireless and encrypted configuration, Pass-
word settings, configuration for date and time, as well as basic server information.
