6.4 DIP Switch Settings DIP-switches are accessible under the lid on top of the unit. Prevent damage to internal electronics from electrostatic discharges (ESD) by discharging your body to a grounding point (e.g. use of wrist strap), before the lid on top of the modem is removed. ! Warning! Do not open connected equipment. Prevent access to hazardous voltages by disconnecting the unit from AC/DC mains supply and all other electrical connections.
6.4.1 MAC address The MAC address of the unit can be found on the product label “00 30 56 F” + last 5 digits on IC2 see figure in section 6.4 Switch settings on page 12. Example: Label on IC2 “SC12 RTOS 0092C2” this will give the unit MAC address “00 30 56 F0 92 C2” The MAC address can also be find out with the DOS command “ARP –a”. (Perform the “PING” command with the ED-10 local IP address before the ARP command.) 6.
7. Functional description The ED-20 can be in either configuration mode or in application mode. Normally the ED-20 is in application mode, where the serial-to-network data transfer is enabled and all configuration settings are readable. Change of configuration parameters are done in ED-20 configuration mode. Configurable parameters are listed in chapter 6.3. 7.1 Application mode In application mode the ED-20 transfers data between the serial interface (CH1) and the network interface (10BaseT).
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.
8.

Dial IN/OUT Select the operating mode of the ED-20. -Dial IN, The unit will act as an PPP Server and only accept incoming calls. Modem Connect (Dial OUT) and the Brouter function will be disabled. -Dial IN/OUT, The unit will act both as an PPP Server and an PPP Client. When an incoming call is detected then the PPP Client is disabled. –Dial OUT, The unit will act as an PPP Client and not accept incoming calls. Modem Connect (Dial IN) and the function Connect at PWR on will be disabled.
Escape Sequence When communication is established with another modem it is still possible to reach the command mode by sending an escape sequence to the modem. Note! Refer to the user guide or installation manual to the attached modem. Default: +++ Escape Delay Define the delay time in seconds after the escape sequence been sent until the next AT-command will be sent.
Modem Hangup Command Hangup string that will be sent to the modem. Default: ATH Answer Expected answer from the modem on the sent command. Default: OK Timeout Define the time in seconds between the sent command and the expected answer before the command have failed.

Allowed values: 0 to 9999 Default: 1 Modem Connect (Dial Out) Command Dial out string that will be sent to the modem.
Answer Command that will answer the incoming call. Default: ATA Timeout Define the time in seconds, For how long time the ED-20 will accept incoming calls from power-up. Normally not used, leave as is. Allowed values: 0-9999 Default: 0 8.2.3 Network Settings Login The login username and password is used on the dial-in connection and when the ED-20 is configured with ED-Tool for ED-20 over a network connection. Authentication Select if authentication shall be used over the PPP link or not.
PPP Network Interface These values is used when the ED-20 is in Server mode. The server will provide the IP addresses for the PPP link. Note! When connecting to a private remote network via the ED-20 using Windows network connection wizard, Always Obtain an IP address automatically Local IP* When the ED-20 is in server mode, this will be the Servers IP address on the PPP link Note! The Network ID must be different than the Network ID on the remote network and the Network ID locally.
8.2.4 Brouter settings The brouter function will initiate outgoing connections. This function is only available in PSTN + Dial Out mode (Refer to section 8.2.2 – General – Modem settings and Dial IN/OUT.) When a IP packet sent to the ED-20 have a IP Address that match a IP Address in the entry list, the ED-20 will send the connect message to the attached modem.This will result in an connection to another location and establishment of a PPP link.
