Technical Data i-modul GPRS/EDGE 3.1 3.3.1 Exemplary Calculation for Dimensioning a Back-Up Capacitor A back-up capacitor is dimensioned based on an existing power supply of 5 V/1 A. C U ( I max L I U q ) * t ESR U mod The following applies: t: Duration of a transmit burst t = 577µs I q : The voltage controller can supply a current I q of 1 A at 5 V in this example. I L : The GSM engine can be considered as a current sink with an I L of 2.5 A in the moment of the transmit burst. This is the maximum possible value, which may occur. The actual value depends on the quality of the GSM signal at the site and the adaptation of the antenna. ΔU max : maximum allowed voltage drop (from the nominal voltage) at the GSM engine (during the transmit burst). Specification: ΔU max = 400 mv U mod : Voltage drop at the connector transitions of the i-modul GPRS/EDGE 3.1 Ethernet. Typically: U mod = 100 mv U ESR : Voltage drop at R ESR (equivalent series resistor) of the used electrolytic capacitors. Assumption: U ESR 100 mv This results in the specified case for the capacitor C: (2,5A 1A) *577s C 400mV 100mV 100mV 4327,5F This result is the lower limit for the capacity. Moreover, aging (by thermal load) as well as the high tolerance of electrolytic capacitors (typically 20%) must be observed. In order to keep the influence of the ESR (equivalent series resistance) of the capacitor as low as possible, the capacity should be divided into several capacitors 10

i-modul GPRS/EDGE 3.1 Technical Data connected in parallel (preferably low ESR types). In order to provide sufficient reserve, a parallel connection of 2 pcs. 2200 µf and one 1000 μf electrolytic capacitors with 10 V dielectric strength is recommended for example. The compliance of the ESR must be tested again after selecting the components. RESR U ESR 100mV U ESR RESR 66, 67m I I I I 2,5A 1A L q L q The complete ESR of the used capacitors should not exceed a value of 66.67 mω to comply with the assumption of U ESR = 100 mv made in the capacity calculation. Example: Electrolytic capacitors from the LXZ series of "NIPPON CHEMI-CON" are used: LXZ 10 VB 1000 J16 for 1000µF with an RESR of typ. 68 mω LXZ 10 VB 2200 K20 for 2200µF with an RESR of typ. 38 mω R ESRtot = 68 mω 38 mω 38 mω = 14.85 mω Moreover, it must be observed when designing the power supply, that the back-up capacitors are placed as close as possible to the connector transitions of the module, and the VCC tracks are as wide as possible to reduce the line resistance here. 11

Technical Data i-modul GPRS/EDGE 3.1 3.4 SIM card The i-modul GPRS/EDGE 3.1 Ethernet requires a 3 or 1.8 Volt SIM card from a GSM provider for operation. The SIM card is the identification against the network provider. The SIM card must be inserted into the holder with the contacts facing down that the contacts get contact. Caution! Damage of the SIM card! Function loss of the SIM card. Changing the SIM card must only be performed with deenergized device. Moreover, it is possible to route the pins 26-30 outside to implement an external SIM card holder. Otherwise, the pins remain unconnected. Certain approval guidelines are valid for implementing an external SIM card holder, e.g. the maximum line length and the used SIM card holder are defined. Refer to support@insys-tec.de for more detailed information. 12

i-modul GPRS/EDGE 3.1 Connections 4.5.3 Indication Signals Pin Signal Type Description 25 STATUS Output Optional output for connecting a TTL logic or a low-power LED. A serial resistor (820 Ohm) against GND is present. On: low resistance against GND Signalling: Initialisation phase: Slowly blinking (500 ms on, 500 ms off) during boot procedure Normal operation: Off: not registered with the GSM network Slowly flashing (100 ms on, 1900 ms off): registered with GSM network On: PPP connection to the Internet established 31 SIGNAL Output Optional output for connecting a TTL logic or a low-power LED. A serial resistor (820 Ohm) against GND is present. On: low resistance against GND Signalling: Indicates the field strength of the received signal by blinking (the faster, the better). 32 SYNC Output Optional output for connecting a TTL logic or a low-power LED. A serial resistor (820 Ohm) against GND is present. On: low resistance against GND Signalling: Indication of the GSM/GPRS transmit burst. The SYNC pin will be enabled 180 µs before a transmit burst and remains enabled during the transmit burst. On the one hand, this can indicate any send activity of the GSM/GPRS engine generally via an LED. On the other hand, this can be used to determine the time of increased power consumption to be able to supply the i-modul with sufficient power. Table 8: Pin specifications - indication signals 17

Connections i-modul GPRS/EDGE 3.1 4.6 Connection Example for Indication Signal Figure 5: Connection example of an indication signal 18

i-modul GPRS/EDGE 3.1 Connections 4.7 Connection Example for the SIMPRES Input SIMPRES informs the GSM engine whether a SIM card is inserted (low signal) or not (high signal). If the GSM engine detects that a SIM card is inserted, it enables the supply voltage for the SIM card. For the case that the SIMPRES input is not to be used in the application, a pulldown resistor pretends the presence of a SIM card to the GSM engine that this enables a continuous SIM supply. If SIMPRES is to be used, this pull-down resistor must be "overwritten". For this, use the circuitry in Figure 6. If the switch S1 is open, T1 connects through and VCC_+5V is present at the SIM- PRES input via R3. R3 forms a 1:1 voltage divider with R2 (on the i-modul), which results that approximately 2.5V (high) are present at the SIMPRES input. The GSM engine interprets this as "No SIMCARD" and disables the SIM supply voltage. If the switch S1 is closed, T1 blocks and SIMPRES is connected to GND (low) via R2. The GSM engine interprets this as "SIMCARD inserted" and enables the SIM supply voltage. If VCC = 3.3V, the resistor R3 of the shown circuit must be replaced with 1k. Figure 6: Connection example for the SIMPRES input 19

Functions i-modul GPRS/EDGE 3.1 Under "DynDNS State", the state of the DynDNS registration of the current WAN IP address is displayed. The status values can be output in text form by entering "http://<ip- Adresse>/status.txt" into the address line of your web browser (e.g. http://192.168.1.1/status.txt). 8.2 GSM/GPRS The WAN connection establishment, the mobile radio parameters, the periodic logout/login or the periodic restart and the connection check are configured on the "GSM/GPRS" page. 8.2.1 Establishment of the WAN Connection The WAN connection can either be established automatically or controlled via input 1. The WAN connection will be re-established following every restart and every interruption for an automatic connection establishment. If the connection establishment is controlled via input 1, the connection will be established, if input 1 is closed, i.e. connected to GND. As soon as the connection is established, output 1 will be enabled. Output 1 remains enabled as long as the connection is established. If input 1 is opened again, the WAN connection will be terminated again. Configuration with the web interface In order to establish the WAN connection automatically, select under "WAN-LINK" the radio button "always on". In order to establish the WAN connection controlled via input 1, select under "WAN-LINK" the radio button "controlled by Input IN1". Save your settings by clicking on "Save". Changed settings become only effective after a restart. 8.2.2 Mobile Radio Parameters Besides the PIN of the SIM card and the GPRS access data, the selection of the network provider will be specified here. If no network provider is specified here, an automatic network selection will be made, i.e. the i-modul GPRS/EDGE 3.1 Ethernet tries to register with the own network provider. If this fails, the i-modul GPRS/EDGE 3.1 Ethernet registers with the strongest available network provider. If an exclusive network provider is specified, the i-modul GPRS/EDGE 3.1 Ethernet will only try to register with this. If a preferred network provider is specified, an automatic network selection will be made, if the preferred network provider is not available. The i-modul GPRS/EDGE 3.1 Ethernet will need the PIN of the inserted SIM card (if the SIM card is protected by a PIN) to register with the mobile network and establish CSD or IP connections. 26

i-modul GPRS/EDGE 3.1 Functions It is necessary for a CSD connection to enter a phone number (e.g. the Internet provider). For a packet-based connection (GPRS/EDGE), the APN (Access Point Name) of your network provider must be entered. Depending on the network provider, a user name and a password may be necessary for the PPP dial-up. "*99***1#" must be entered as phone number for a packet-based connection. Note Loss of function of the SIM card! An incorrectly entered PIN can cause that the SIM card will be locked after a wrong code has been entered for three times. Take care, that the passed SIM PIN corresponds with the SIM card or disable the PIN request of the SIM card. A possibly configured PIN has no influence if the PIN request is disabled.

Functions i-modul GPRS/EDGE 3.1 forwarding are used. Only the public IP address of the i-modul GPRS/EDGE 3.1 Ethernet can be reached in the Internet. This IP address can still be used to access the local end terminals in the network of the i-modul GPRS/EDGE 3.1 Ethernet from the Internet, if NAT and port forwarding are used. Using Network Address Translation (NAT), the i-modul GPRS/EDGE 3.1 Ethernet replaces the source address of the packets of an outgoing connection with its own. The i-modul GPRS/EDGE 3.1 Ethernet stores the actual source address in its NAT table. If it receives a reply packet of the remote terminal of this connection, it replaces the destination address of the packet with the address of the original source. The i-modul GPRS/EDGE 3.1 Ethernet provides port forwarding. The i-modul GPRS/EDGE 3.1 Ethernet routes incoming packets from outside of the network to certain computers within the network. Outgoing packets of these connections from the network are being routed back to their destinations outside of the network. At certain ports, the i-modul GPRS/EDGE 3.1 Ethernet routes incoming data packets to one port of a certain destination address. You can use static rules to define which packets from outside are routed to which addresses and ports in the network. This means that you can make certain services available to computers in the network, using the Internet. 30 Configuration with the web interface In order to specify the time without data traffic that must expire before a connection entry in the NAT table will be marked as inactive, enter under "TCP-Timeout" the time in minutes. Inactive entries will be deleted from the NAT table, if there is not sufficient space for new entries. The NAT table can contain a maximum of 1024 entries. Save your settings by clicking on "Save". Changed settings become only effective after a restart. In order to create a new static NAT entry, enter under "New static NAT- Entry" the port on the WAN side of the i-modul GPRS/EDGE 3.1 Ethernet, at which IP packets are to be accepted, into the "WAN Port" field, the IP address of the destination computer in the local network into the "LAN IP Address" field and the port of the destination computer in the local network into the "LAN Port" field, and select in the drop-down list field "Protocol" the expected protocol. Click on "Save" then to take over the entry. A maximum of 20 static NAT entries can be entered. In order to delete an existing entry, click under "List of static NAT- Entries" on "Delete" behind the respective entry. The NAT table can be output in text form by entering "http://<ip-adresse>/nat.txt" into the address line of your web browser (e.g. http://192.168.1.1/nat.txt). The complete NAT table can be deleted permanently by entering "http://<iphttp://192.168.1.1/format_nat). Adresse>/format_nat" into the address line of your web browser (e.g.

i-modul GPRS/EDGE 3.1 Functions 8.5 DynDNS The parameters for the DynDNS service are configured on the "DynDNS" page. 8.5.1 Dynamic DNS Update The i-modul GPRS/EDGE 3.1 Ethernet can forward the IP address, which it was allocated during Internet dial-up, to a DynDNS provider, so it can be reached from the Internet with a domain name. This means that the network behind the i-modul GPRS/EDGE 3.1 Ethernet can always be reached with the same domain name from the Internet, also for dynamically allocated IP addresses (if the allocated IP address for incoming connections is not protected). The i-modul GPRS/EDGE 3.1 Ethernet will update the IP address connected to the domain name at the DynDNS provider during each dial-up. For this function, you will need an account with a DynDNS provider. A public IP address must also be provided from the provider for packet-based mobile connections (GPRS/EDGE). Otherwise, the device cannot be accessed despite this service. Configuration with the web interface In order to perform a dynamic DNS update, enter the domain name to be updated that is intended and registered for the i-modul GPRS/EDGE 3.1 Ethernet under "DynDNS Hostname" (maximum 40 characters). The DynDNS procedure generates data traffic that may cause costs depending on the contract. If you do not need a dynamic DNS update, this field must be left empty whereby this function is disabled. Enter the user name for DynDNS authentication under "DynDNS Username" (maximum 15 characters). Enter the password for DynDNS authentication under "DynDNS Password" (maximum 15 characters). To confirm the correct entry, enter the password once more into the field below. Select the DynDNS service from the drop-down list field under "DynDNS System". If the free service is used, "dyndns" must always be selected here. Enter the name of the DynDNS server under "DynDNS Server". This is generally "members.dyndns.org" for the provider DynDNS. Since the update protocol is pretty simple, an own DynDNS service can be installed and the appropriate DynDNS update server can be specified here. This is beneficial if the i-modul GPRS/EDGE 3.1 Ethernet is part of a VPN. Save your settings by clicking on "Save". Changed settings become only effective after a restart. 31

CE/EMC Compliant Integration i-modul GPRS/EDGE 3.1 38 11 CE/EMC Compliant Integration When integrating the i-modul GPRS/EDGE 3.1 Ethernet into an application, the sysof the entire device. In or- tem integrator is responsible for the CE/EMC conformity der to integrate the i-modul GPRS/EDGE 3.1 Ethernet CE and EMC compliant into your application, we recommend the following for you to observe during develop- ment. 11.1 Your Application The motherboard for the i-modul must be designed according to the applicable CE/EMC guidelines. Always observe short signal lines and sufficient ground surface. Connect the i-modul with a conducting spacer bolt to the device ground. If you develop a platform, which is compatible with several, different i- moduls, you must maintain the respective design criteria for each i-modul (especially concerning the phone connection). The PCB tracks to the i-moduls with network interfaces, like Modem, ISDN, and Ethernet, must be designed with a track distance of 2.5 mm between the tracks of the network interface and all other signals (refer to EN60950). 11.2 Application Interface / Terminal Strip P1 The TTL RS232 interface should be equipped with ferrite beads directly at the module to reduce interference signals from the motherboard. It is also beneficial to design capacitors (preferably SMD) at all RS232 and I/O signal lines to GND, which can be equipped when needed. Short lines to the connector and good ground are important. The recommended value for capacitors is 22 pf to 47 pf. 11.3 Network Interface / Terminal Strip P2 (for Modem /ISDN) The line to the network interface (line from i-modul to device socket) should be as short as possible and not be routed close to sources of interference (e.g. switching power supplies). Provide the line with ferrite beads directly at the device socket. The phone interface (not for i-modul with Ethernet interface) should be provided with standard ferrite beads (e.g. Murata BLM31A601SPT or Würth Elektronik type 74279213) and with optional ceramic capacitors (100 pf/2 kv, Y2 standard) to ground. In case of extended requirements to the interference resistance of the phone line (especially burst), a current compensated impedance (e.g. Epcos B82790-C2475-N340 or Würth Elektronik type 744202) can be used. The strip conductors on the Ethernet side should have a wide design (minimum 24 mil).

i-modul GPRS/EDGE 3.1 CE/EMC Compliant Integration Ethernet receive PCB tracks must provide a minimum width of 25 mil, Ethernet transmit PCB tracks a minimum width of 100 mil (1 mil 0.0254 mm). The PCB tracks must be routed parallel and have the same length. 11.4 Antenna Connection (if equipped) The antenna connection must be connected to ground and a ferrite ring must be installed behind the ground connection (towards i-modul) to increase the interference resistance against burst and ESD at the antenna connection. 11.5 Further Recommendations The required measures will mostly depend on the connections and the layout (especially of the ground surfaces and good ground connections) of the motherboard. To save costs, some of the above mentioned capacitors or ferrite beads may be omitted. However, they should be considered in the layout to be able to integrate it without having to change the PCB, if the EMC tests show that these components are necessary. For the Ethernet module, insert bridges instead of the ferrite beads, while the ceramic capacitors remain unequipped. 11.6 Reference Documents Our evaluation board may be helpful for designing your application.

International Safety Instructions i-modul GPRS/EDGE 3.1 12 International Safety Instructions 40 12.1 The following safety instruction of Cinterion is valid for the used GPRS engine TC63i or EDGE engine MC75i. Following US FCC specifications, each device must have a sticker with a note referring to the FCC ID attached. Safety Precautions The following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating TC63i/MC75i. Manufacturers of the cellular terminal are advised to convey the following safety information to users and operating personnel and to incorporate these guidelines into all manuals supplied with the product. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. Cinterion assumes no liability for customer s failure to comply with these precautions. When in a hospital or other health care facility, observe the restrictions on the use of mobiles. Switch the cellular terminal or mobile off, if instructed to do so by the guidelines posted in sensitive areas. Medical equipment may be sensitive to RF energy. The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be affected by interference from cellular terminals or mobiles placed close to the device. If in doubt about potential danger, contact the physician or the manufacturer of the device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep their hand-held mobile away from the pacemaker, while it is on. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it cannot be switched on inadvertently. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communications systems. Failure to observe these instructions may lead to the suspension or denial of cellular services to the offender, legal action, or both. Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard. Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. Remember that interference can occur if it is used close to TV sets, radios, computers or inadequately shielded equipment. Follow any special regulations and always switch off the cellular terminal or mobile wher- it may cause interference or danger. ever forbidden, or when you suspect that Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a vehicle, unless it is securely mounted in a holder for speakerphone operation. Before making a call with a hand-held terminal or mobile, park the vehicle.

i-modul GPRS/EDGE 3.1 International Safety Instructions Speakerphones must be installed by qualified personnel. Faulty installation or operation can constitute a safety hazard. IMPORTANT! Cellular terminals or mobiles operate using radio signals and cellular networks. Because of this, connection cannot be guaranteed at all times under all conditions. Therefore, you should never rely solely upon any wireless device for essential communications, for example emergency calls. Remember, in order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Some networks do not allow for emergency calls if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features before you can make an emergency call. Some networks require that a valid SIM card be properly inserted in the cellular ter- mobile. minal or Note Export restriction for FCC! Possible offence against approval regulations. If the final product is not approved in the U.S. territories, the application manufacturer shall take care that the 850 MHz and 1900 MHz frequency bands be deactivated and that band settings be inaccessible to end users. If these demands are not met (e.g. if the AT interface is accessible to end users), it is the responsibility of the application manufacturer to always ensure that the application be not exported to countries within the area of validity of the FCC. 41
