Iridium 9603 SBD Transceiver Product Developers Guide Revision 1.0 1 Product Overview The Iridium 9603 Short Burst Data Only Transceiver (9603) is designed to be integrated into a wireless data application with other host system hardware and software to produce a full solution designed for a specific application or vertical market. Examples of these solutions include tracking a maritime vessel or automatic vehicle location. The 9603 only supports Iridium’s Short Burst Data (SBD) capability. It does not support voice, circuit switched data, or short message service (SMS). The 9603 is designed to meet the regulatory requirements for approval for FCC, Canada, and CE assuming an antenna with a gain of ~3 dBi and adequate shielding. This allows the 9603 to be integrated into a variety of wireless data applications or retrofitted into existing SBD-only applications that utilize SBD with the current Iridium 9602, 9601, 9522A, 9522B or 9522 L-Band transceiver- based products. (Note that additional development work will be required). Such finished products, when integrated together, require regulatory and safety testing to be conducted by the integrator. The 9603 is a single board transceiver provided as a ‘black box’ transceiver module with all device interfaces provided by a single multi-pin interface connector in addition to the antenna connector. The Product only provides the core transceiver. All other end user Field Application functions such as GPS, microprocessor based logic control, digital and analog inputs, digital and analog outputs, power supply and antenna must be provided by the solution developer. The device interface across the user connector consists of a serial-data interface, DC power input, network available output and a power on/off control line. The 9603 does not incorporate nor require a Subscriber Identity Module (also known as a SIM Card) to be inserted into the Transceiver. The 9603 is intended to be used as a transceiver module fitted within another host system. The 9603 module is designed to comply with the standards for Radio Emissions Compliance, Electromagnetic Compatibility, and AC Safety in the United States, European Union and Canada, for host systems that provide safe connections to power supply and external antenna or cable distribution system. The Iridium 9603 is described within this document as “Iridium 9603,” “9603 SBD Transceiver,” “Transceiver,” “Modem,” and “ISU.” All of these terms refer to the same product. 1.1 Key Features  Single board transceiver  Small form factor  No SIM card  Designed to be incorporated into an OEM solution  Maximum mobile originated message size 340 bytes  Maximum mobile terminated message size 270 bytes  Automatic Notification to the Transceiver that a mobile terminated message is queued at the Gateway  Global operating capability  RoHS compliant Proprietary & Confidential Information 7 Distribution of guide restricted to product developers only • Information contained in this guide is subject to change without notice.

Iridium 9603 SBD Transceiver Product Developers Guide Revision 1.0 2.2 Mechanical Dimensions – Motherboard Mounting The Iridium 9603 SBD Transceiver must be fitted within an enclosed host system. With appropriate external connections, the host system motherboard and host system enclosure can be designed to meet full transceiver regulatory tests. The Iridium 9603 SBD Transceiver is provided with two mounting holes on the opposite side from the system connector. The module should be assembled onto the motherboard of the host system, by pushing the module onto matching connectors on the motherboard and then securing the two mounting holes to the motherboard using screws.

Iridium 9603 SBD Transceiver Product Developers Guide Revision 1.0 Figure 5. Motherboard mounting suggestions for the 9603 Transceiver 1. This example of a host system motherboard footprint is shown for illustrative purposes only. The host system may require a different PCB layout or mechanical arrangement. 2. The 9603 is designed to be incorporated within a host system. As such, the antenna or cable distribution system that feeds the host system should be terminated in a robust RF connector that is suitable for the end-application. 3. Safety isolation requirements for external antennas or cable distribution systems should also be taken into consideration when designing the motherboard. A suitably safe design for the RF connections should be incorporated into the host system motherboard, ideally using a chassis-bonded ground connection to the antenna cable shield. 4. The surface below the modem should be a conductive ground plane such that the modem bonds to the motherboard ground system thus reducing the possibility of radiated emissions. This also requires that the mounting screws be properly tightened to 10 cNm of torque. 5. The modem is to be installed in a “service access only” area not accessible by untrained personnel. Warning- Although the modem dissipates very little power, its use in ambient temperatures in excess of 60 degrees C will make the caseworks considerably hot.

User Connector Pin Number Designation 3.2 DC Power Interface The DC power interface is comprised of the DC power inputs and a control signals as summarized in Table 7. The +5V Inputs and 0V supply returns are used to supply DC power to the 9603 and ensure that enough current can be drawn across the connector without the 9603 malfunctioning during transmit due to lack of current supply. Note that all power and ground pins should be connected externally. The DC power supply requirements for the 9603 are summarized in Table 9 below. Note that these requirements apply to DC power measured at the 9603 User connector input and not at the output of the power supply. Long power supply cables can cause a voltage drop sufficient to cause the voltage to be out of specification at the physical power supply input to the 9603.

The external power supply needs to guarantee the following:  The supply voltage droop over for a 8.3ms burst of 1.5A current should not be more than 0.2 Volts. 1  The power supply should limit the in-rush current to 4 Amps maximum  The power source shall provide for over current protection in case of device malfunction.  The supply noise should be less than the limits in the following profile: 100 mVpp from 0 to 50 kHz 5 mVpp at 1 MHz measured in 50 kHz bandwidth 10 mVpp at 1 MHz measured in 1MHz bandwidth 5 mVpp above 5 MHz measured in 1 MHz bandwidth. 1 In rush limit refers to the impedance of the modem when it is unpowered is very low. When power is supplied from an unlimited supply the instantaneous current can exceed 4 Amps If the current exceeds this value damage can occur. This can be limited in several ways, included using a supply that cannot provide more than 4 Amps instantaneously; or providing some series inductance/resistance to the supply lead.

Iridium 9603 SBD Transceiver Product Developers Guide Revision 1.0 3.2.1 Power On/Off Control An external on/off input is provided on a pin of the User connector. The 9603 starts up when power is applied and the power on/off input is high. As long as the input voltage is applied, logic high on this line turns the transceiver on and a logic low turns it off. If this line is not required then it must be connected directly to the +5 V supply. Note that this on/off control is similar to the Iridium 9601 and 9602 products, but it is not the same as the 9522, 9522A or 9522B products. Prior to turning off the modem a “flush memory” (AT*F) command should be issued to ensure all memory write activity is completed. When a transceiver has been turned off, Product Developers should not reapply power on a unit until more than 2 seconds has elapsed after power has reached 0V. Additionally, if a unit does not respond to AT commands, power off the module, wait for 2 seconds and then power it back on. When a 9603 is powered off the power on reset circuit requires 2 seconds for voltages to decay. If the 2 second wait time is not adhered to the reset circuit may not operate and the modem could be placed in a non-operational state. The state is not permanent and can be rectified by the above procedure. 3.2.2 Typical Power Usage Profile This section is designed to give the Product Developer some insight to the electrical power profile that the 9603 uses. It does not describe every situation and permutation possible. It should be used as a starting point for the Product Developer to continue its own development design. The actual usage profile can vary for a number of reasons: 1) View of the sky – if in poor visibility of the sky where a clear line of sight is not available between the transceiver and the satellite. 2) The higher the antenna VSWR the higher the current consumed 3) How often the 9603 module is activated/deactivated by the Host Controller system 4) Manufacturing variation from transceiver to transceiver. The host system designer should ensure their design covers for worst case power consumption scenarios.

Iridium 9603 SBD Transceiver Product Developers Guide Revision 1.0 3.3 Serial Data Interface The data/fax serial interface is an RS-232 9-wire interface at 3.3V digital signal levels over which the 9602 and FA transfer commands, responses, and SBD message data. With respect to this interface, the 9602 behaves as a DCE (Data Communication Equipment), and the FA behaves as a DTE (Data Terminal Equipment). If RS-232 voltage levels are needed, the FA must include an LVTTL/RS-232 level-shifter. Autobaud is not supported. The baud rate can be set via the AT+IPR command. The default rate is 19200 bps. See the ISU AT Command Reference Specification for information on the data/fax interface. 3.4 Network Available Output This is a digital output that can be used by an application to know when the transceiver has visibility to the satellite network. This is useful in applications where the transceiver may move around terrain that reduces the amount of time that clear line of sight to the satellite constellation is available. The Product Developer can use this output to preserve battery life by reducing the number of attempted transmissions by including this logic output in the application decision logic. Network Available means only that the 9603 can successfully receive the Ring Channel, or, put more simply, it can see an Iridium satellite. Network Available is not a guarantee that a message can be successfully sent. The Network Available state is evaluated every time the Ring Channel is received or missed. If the Ring Channel is visible, then that is typically every 4 seconds. If the Ring Channel is not currently visible, then the update period can be as long as 2 minutes, depending on how long the lack of satellite visibility existed. This is because the 9603 attempts to conserve power by increasing the ring search interval while the satellites are not visible. Every time a ring search fails, the time to wait is increased and eventually limits at 120 seconds. If Network Available is currently off, the Field Application may still attempt an SBDI[X] session. This will force the 9603 Transceiver to look for the Ring Channel immediately, and on finding it, to attempt to send the message. In this case Network Available will not come on immediately. The Network Available does not turn on while in a +SBDI session. It will however turn on 4 seconds later assuming that the Ring Channel is present. After the SBD session completes, the 9603 performs a new Ring Channel search sequence, at the end of which Network Available gets turned on. That can take between 4 and 12 seconds. The wait time between search windows is reset to 4 seconds every time a search succeeds. Otherwise it continues to increase. So if the +SBDI attempt fails to find the ring channel, the search window does not reset to 4 seconds. Note that the behavior of +CIEV:1 is identical in to that of the Network Available output. 3.5 DC Supply Indicator Output A DC supply indicator signal is provided by the 9603 which could be used directly for driving an LED to provide a visible indication that the Transceiver supply is on. Alternatively the output signal could be used in application logic to determine if the internal Transceiver power supply is on.

Iridium 9603 SBD Transceiver Product Developers Guide Revision 1.0 4 RF Interface This section describes the physical characteristics of the RF connectors and specifications of the RF Interface. 4.1 RF Connector The 9603 RF connector is a U.FL connector produced by Hirose. The part number is U.FL-R-SMT-1. This is a surface mount connector that is directly attached to the 9603 module. The U.FL connector mates with a pigtail which can link to an antenna. Note - this 9603 module has a different antenna connector than other Iridium transceivers. Note that for safety reasons, the RF connector on the 9603 module should not be directly connected to an external antenna cable or cable distribution system. Paragraph 7.3 of EN60950-1:2006 safety standard requires that users are protected against high voltages that might appear on these cables. This can be achieved either by inserting a high-voltage isolating capacitor in series with the signal or by grounding the shield of the coaxial cable. The 9602 RF connector has limited voltage capacity; therefore, protection needs to be provided in the host application. Developers are encouraged to review the EN60950-1:2006 standard for additional details. 4.2 Antenna Characteristics The 9603 should be connected to an Iridium-band antenna with the following antenna connector characteristics as described in Table 11. Table 11: Antenna Characteristics Parameter Value Impedance 50 Ohms nominal Gain (maximum) 3dBi Polarization RHCP VSWR (in Iridium band) 1.5:1 VSWR (out of band) 3:1 Note:  Existing certified antennas will require different RF connector types than those for the 9601, 9602, 9522, 9522A and 9522B 4.3 RF Interface Specifications The RF interface requirements for the 9603 are summarized in Table 12 below. Table 12: General RF Parameters Parameter Value Frequency Range 1616 MHz to 1626.5 MHz Duplexing Method TDD (Time Domain Duplex) Input/Output Impedance 50Ω Multiplexing Method TDMA/FDMA Proprietary & Confidential Information 22 Distribution of guide restricted to product developers only • Information contained in this guide is subject to change without notice.

Iridium 9603 SBD Transceiver Product Developers Guide Revision 1.0 4.4 Radio Characteristics Table 13 contains radio characteristics of the 9603 SBD Transceiver. Table 13: Radio Characteristics Parameter Value Average Power during a transmit slot (max) 1.6 W Receiver sensitivity (Typical level at module connector) -117dBm Max Cable loss permitted (Note 1) 2dB Link Margin – Downlink (Note 2) 13dB Link Margin – Uplink (Note 2) 7dB Note 1: Cable losses should be minimized. The total implementation loss for an antenna, connectors, cable, lightening arrestor and any other RF component between the transceiver and the antenna should not exceed 3dB. The total cable loss between the antenna and the modem includes losses in the motherboard. Implementation loss higher than this will affect the Iridium link performance and quality of service. Solutions with a loss higher than 3dB will not meet the requirements of Iridium Solution Certification. Note 2: Link Margins are given assuming a free-space propagation model. 4.5 S-meter Performance The numbers “reported over the AT command interface indicate the signal strength of the ring channel. Care should be taken when using the S-meter readings for comparisons between devices. Of particular note are the following: 1. There is a 0.5 dB tolerance on calibrating the S-meter. 2. Each bar represents a 2 dB increment 3. Multiple ring channels can be present at the same time so units can lock to different signals. 4. If the reading is near the decision threshold it would be easy to see a 1 bar difference Proprietary & Confidential Information 23 Distribution of guide restricted to product developers only • Information contained in this guide is subject to change without notice.

Iridium 9603 SBD Transceiver Product Developers Guide Revision 1.0 5 AT Command Set Description The 9603 is configured and operated through the use of AT commands. See the “ISU AT Command Reference” for the full set of AT commands and responses. Note that versions 3.2 and earlier of the ISU AT Command Reference do not mention the 9603. Subsequent versions of the reference will do so. At the time of writing of this version of this document, all information contained in the ISU AT Command Reference for the 9602 applies equally to the 9603. For differences in AT command support between 9603 software releases, see the relevant software release notes, which are made available to authorized Iridium VARs and VAMs on the Iridium Developer Extranet. It is the responsibility of Product Developers to check compatibility of applications software with the AT Commands on all 9603s used for both development and commercial deployments. See also the “Iridium Short Burst Data Service Developers Guide” for information on how SBD operates on the Iridium system.
