2. Description of ER75i router 2.1. Introduction EDGE router ER75i is a compact electronic device based on the MC75 module of SIEMENS which enables data transfers using GSM, GPRS and EDGE technologies. Primarily, the ER75i router expands the capabilities of the MC75 module by the option of connecting more PCs by means of the built-in Ethernet interface. In addition, the firmware of the ER75i router provides automatic establishment and maintenance of GPRS connection.
Basic delivered set of ER75i includes: • EDGE router ER75i • power supply • crossover UTP cable • external magnetic antenna • installation CD containing instructions and drives In addition to the basic it is possible to deliver: • modul of port PORT1 (RS232, RS485, RS422 a MBUS) • USB A-B cable • External magmetic antenna • plastic clips for the DIN bar with fixing screws Router ER75i is standardly designed for • mounting to a panel using through holes.
2.4. SIM Card Reader The SIM card reader for 3 V and 1.8 V SIM cards is located on the front panel of the modem. For putting the modem into operation it is necessary to insert an activated SIM card with unblocked PIN in the reader. 1. Make sure that the modem is not being power-supplied. 2. Press the small yellow button next to the reader to eject the reader holder. 3. Insert the SIM card in the reader holder and slide it in the reader. 2.5. Power Supply ER75i requires +10 V DC to +30 V DC supply.
2.7. Description of individual components of ER75i 2.7.1. GSM/GPRS/EDGE module SIEMENS MC75 OEM module is used for GSM network wireless communication. It is integrated in the printed circuit board. The slide-out SIM card reader is accessible from the front panel. The FME antenna connector is accessible from the back panel. The MC75 module is equipped with the USB 2.0 Full Speed interface which is brought to the USB-B connector marked USB.
Integrated Dynamic DNS client allows automatic updating of third order domain, which it is provides by server www.dyndns.org so, that this domain will always route on IP address subsidiary GSM operator. The modem settings are saved in the FLASH EEPROM memory. All configuring of the modem can be done through a web interface (HTTP) which is security passwords. 2.8.

3. Configuration setting Monitoring of status, configuration and administration of the ER75i router can be performed by means of the web interface which is available after entering the IP address of the modem in the web browser. The default IP address of the modem is 192.168.1.1. Configuration may be performed only by the user "root" with initial password "root".
3.2. DHCP Status Information about IP addresses which was allotted of DHCP server to ER75i, it is possible find in menu in sum DHCP: • • • • • lease 192.168.1.
3.3. IPsec status Information on actual IPsec tunnel state it can be call up option entries NTP in menu. Detailed information description here painted it can be find on the following link http://www.freeswan.org/doc.html. 3.4. GPRS Status The item GPRS in menu contains information about PLMN (code of operator), cell, channel and signal (information are by a single application find out on power up MC75).
3.6. System Log In case of any problems with connection to GPRS it is possible to view the system log by pressing the System Log menu item. The upper part of the window displays possible errors at GPRS connection establishment. After switching on the log daemon by pressing the Start button, the bottom part of the window displays detailed reports from individual applications running in the modem. To update the contents of the window press the Refresh button. 3.7.
3.8. GPRS Configuration To enter the GPRS connection configuration select the GPRS menu item. If the Create GPRS connection option is checked, the modem automatically tries to establish GPRS connection after switched on. In the window it is possible to define APN, Username, Password and IP address. If the APN field is not filled in, the APN will be automatically assigned by the IMSI code of the SIM card. If the PLMN is not in book of APN, then will be use default APN “internet“.
Annotation: • • MRU (Maximum Transmission Unit) – it is identifier of maximal size of packet, which it is possible transfer in given environment. MTU (Maximum Receiving Unit) – it is identifier of maximal size of packet, which it is possible received in given environment. By other set it may get to incorrect transmission of data. 3.9. NAT Configuration To enter the Network Address Translation configuration, select the NAT menu item.
Example of the configuration with one connection equipment on the ER75i: At these configuration it is important to have mark election Send all remaining incoming packets it default server, IP address in this case is device address behind ER75i. Connected equipment behind ER75i must have setting Default Gateway on the ER75i. At distant PING on IP address of the SIM card matches connected equipment.
Example of the configuration with more connected equipment: At these configuration the address define Server IP Address equipments wiring behind ER75i. At distant PING matches ER75i. Access on web interface of equipment behind ER75i it is possible by the help of Port Forwarding, when behind IP address of SIM is indicating public port of equipment on which we want come up.
3.10. IPsec Tunnel Configuration IPsec tunnel configuration it can be call - up option Ipsec item in menu. In window it can be define off - side tunnel IP address (Remote External IP Address), address nets behind off - side tunnel (Remote Subnet), mask nets behind off - side tunnel (Remote Subnet Mask), address LAN (Remote Subnet), mask LAN (Remote Subnet Mask), sharable key for both parties tunnel (Pre shared Key), service life keys (Key Lifetime) and service life IKA SA (IKE Lifetime).
