7.1.2.2 PPP connection

The PPP connection can be established over PSTN, Leased Line or private lines.

ED-20 can act as a PPP Server, PPP Client or both.These functions is set on the ‘Modem settings’ tab in ED-Tool for ED-20. See application example on page 30.

Connections can be established in several ways depending on the application:

•Standard PPP dial-up networking tool.

•‘Connect’ command on CH2: or via TELNET

•Using the ‘Brouter’ function.

7.1.2.3 Brouter function

The Brouter function will establish a dial-up connection when valid outbound IP address (Defined on the tab ‘Brouter Settings’ in ED-Tool for Ed-20) is sent to the ED-20.

See application example on page 31.

The connection will be open until one of following is true:

•There is no traffic during and the ‘Idle Time’ parameter is set to a value greater than zero.

e.g. Idle Time is set to 600s and there is no traffic sent to the ED-20 for more than 10 minutes.

•‘Close’ command on CH2: or via TELNET

Note! It may be wise to use the Firewall function while the Brouter function being used to reduce the traffic over the PPP link.

7.1.2.4 Firewall function

The Firewall function can be set-up to allow or block certain IP Addresses through the ED-20. See application example on page 31.

7.2 Configuration mode

Local or remote configuration is managed by ED-Tool for ED-20.

ED-Tool for ED-20 is a Windows based set-up programme which provides easy configuration.

Configuration is possible locally by using serial connection and remote using network (telnet) connection. Configuration mode will be entered automatically by ED-Tool for ED-20. ’Config ’ LED will lit when ED-20 is in configuration mode. (The unit is not in configuration mode until the ‘Write config’ button been pushed.)

The unit will be in configuration mode until a reboot is made.

First time configure: ED-20 is shipped with IP-address 169.254.100.100.

Please make sure that 169.254.100.100 is compliant to your network, before ED-20 is connected. Otherwise use serial interface to locally set a valid IP address compliant with the network in use and not chosen arbitrarily, ask your network administrator when in doubt.
