Proprietary & Confidential Information 16 Distribution of Guide Restricted to Product Developers Only Iridium Communications Inc. 9602 SBD Transceiver Product Developers Guide Revision 1.2 (DRAFT 2) Information Contained in this Guide is Subject to Change Without Notice Notes for Figure 4 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 9602/9602N 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 get properly tightened to 7 pound-inches 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 deg C will make the caseworks considerably hot. Iridium Communications Inc.

The +5V Inputs and 0V supply returns are used to supply DC power to the 9602/9602N and ensure that enough current can be drawn across the connector without the 9602/9602N 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 9602/9602N are summarized in Table 9 below. Note that these requirements apply to DC power measured at the 9602/9602N 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 9602/9602N.

The external power supply needs to guarantee the following: • • • • The supply voltage droop over for a 8.3ms burst of 1.5A (9602)/ 1.3A (9602N) current should not be more than 0.2 Volts. 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. 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.

The 9602/9602N 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 9601 product 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 9602/9602N 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 9602/9602N 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 9602/9602N 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. Figure 6 provides a graphical representation of the typical supply current profile of a 9602 SBD Transceiver sending and receiving SBD messages. Iridium Communications Inc.

The 9602/9602N presents a 9-wire data port to the FA (Field Application), where the interface is at 3.3V digital signal levels. With respect to this interface, the 9602/9602N behaves as a DCE (Data Communication Equipment), and the FA behaves as a DTE (Data Terminal Equipment). The terms “FA” and “DTE” are used interchangeably throughout this document; similarly for the terms “9602” and “DCE”. Autobaud is not supported in 9602/9602N SBD Transceiver. The baud rate can be set via the AT+IPR command. The default rate is 19200 bps. 3.3.1 9-Wire and 3-Wire Operation By default, the serial interface operates as a 9-wire connection. Table 10 describes each of the signals, where “input” means an input to the 9602/9602N, and “output” means an output from the 9602/9602N SBD Transceiver. Iridium Communications Inc.

A subsequent transition of DTR to ON returns the data port to DCE mode and resets it to its power-on state. • The UART test mode is provided for factory testing of the data port UART. An FA should never activate test mode; if it does, the 9602/9602N will stop responding to AT commands until the data port is returned to DCE mode. Active low handshaking output The 9602/9602N drives DSR ON when the data port is in DCE mode, and OFF when the data port is in test mode. The DTE may use this signal as an indication that the 9602/9602N is powered up and ready to receive AT commands. Active low ring indicator output The 9602/9602N drives RI ON when it receives a Automatic Notification from the network that a Mobile Terminated SBD Message is queued at the Gateway, and drives RI OFF after 5 seconds or when the DTE initiates an SBD session, whichever occurs first. Active low handshaking output DCD is driven OFF at all times. Note that the Ring Indicator (RI) pin is used by the 9602/9602N SBD Transceiver to indicate that a Mobile Terminated SBD (MT-SBD) message is queued at the Gateway. The Field Application can monitor this pin and use appropriate AT Commands to command the Transceiver to retrieve the MT-SBD message. The serial interface may be operated with a 3-wire connection, where only transmit, receive and ground signals are used. However the 9 wire interface offers better control and is the recommended implementation. Iridium is only able to provide limited 3-wire interface support. Due to the small code space and limited processing resources of the 9602/9602N the flow control is limited. When operating with a 3-wire connection, the following rules apply: • • • AT&Dn must be set to AT&D0 to ignore the DTR input AT&Kn must be set to AT&K0 to disable RTS/CTS flow control The other output signals may be connected, and operate as follows: • CTS driven ON (low) • DSR operates as normal • RI operates as normal • DCD driven ON (low) Iridium Communications Inc. Proprietary & Confidential Information 25 Distribution of Guide Restricted to Product Developers Only Iridium Communications Inc. 9602 SBD Transceiver Product Developers Guide Revision 1.2 (DRAFT 2) Information Contained in this Guide is Subject to Change Without Notice Notes: 1. RTS/CTS flow control, when enabled, is only used when the data port is in SBD data mode. In AT command mode, RTS is ignored and CTS is driven ON (low). 2. If the DC input to the modem is to be disconnected, the developer will need to “tri-state” the serial interface to prevent a possible latch-up condition. 3.3.2 Configuration Settings The 9602/9602N allows the DTE to configure the data port communication parameters. The three configuration types are active, factory default, and stored. The active configuration is the set of parameters currently in use. They can be changed by the DTE individually via specific AT commands. The factory default configuration is stored in permanent memory. This configuration can be recalled at any time through use of the AT&Fn command. Two groups of settings, or “profiles”, can be stored as user-defined configurations. The DTE first creates desired active configurations and then writes them to memory using the AT&Wn command. These profiles can be designated to be loaded as the active configuration upon 9602/9602N power-up through use of the AT&Yn command. The 9602/9602N can be reset without loss of power to these profiles through use of the ATZn command. The configuration settings are stored in “S-register” locations and are detailed further in the “ISU AT Command Reference”. 3.3.3 Modes of Operation The serial interface is always in one of three modes: command mode, SBD data mode or SBD session mode. When the data port is in command mode, AT commands can be entered to control the 9602/9602N. In command mode, flow control has no effect, with the RTS input ignored and the CTS output driven ON (low). When in SBD data mode, the 9602/9602N is transferring binary or text SBD message data to or from the DTE. In SBD data mode: • All characters from the DTE not forming part of the message data are ignored (i.e. no AT commands may be entered) • No unsolicited result codes are issued. • RTS/CTS flow control, if enabled, is active. When RTS is OFF (high), the 9602/9602N suspends transfer of data to the DTE; when CTS is OFF (high), the 9602/9602N expects the DTE to suspend transfer of data to the 9602/9602N. When in SBD session mode, the 9602/9602N is attempting to conduct an SBD session with the network. In SBD session mode: • The DTE must wait for the +SBDI [X][A]session result code. • All characters from the DTE are ignored. • Unsolicited result codes are issued where those codes have been enabled. Transitions between the modes of operation are performed automatically by the 9602/9602N in response to the SBD AT Commands; the DTE has no other control over the mode. Iridium Communications Inc.

RS-232 interface chips can be fitted to the host system motherboard if connection to an external RS232 link is required. Note that these may invert the digital logic level, so another inversion may be required. 3.3.4.2 Data Port Outputs The five outputs from the 9602/9602N serial port (DCD, DSR, CTS, RI and RXD) are all at 3.3V digital levels. 3.4 Hardware Failure Reporting If the 9602/9602N detects a hardware problem during initialisation, the 9602/9602N may be unable to function correctly. The 9602/9602N notifies the DTE of this situation by issuing an unsolicited result code at the end of initialisation: HARDWARE FAILURE:, where identifies the software subsystem that detected the error, and is the subsystem-specific error code. Any AT commands that cannot be handled in the failure condition will terminate with result code 4 (“ERROR”). 3.5 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 9602/9602N 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 9602/9602N 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 9602/9602N 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 9602/9602N 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.

Proprietary & Confidential Information 27 Distribution of Guide Restricted to Product Developers Only Iridium Communications Inc. 9602 SBD Transceiver Product Developers Guide Revision 1.2 (DRAFT 2) Information Contained in this Guide is Subject to Change Without Notice 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. 3.6 DC Supply Indicator Output A DC supply indicator signal is provided by the 9602/9602N 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. 4 RF Interface This section describes the physical characteristics of the RF connectors and specifications of the RF Interface. 4.1 RF Connector Types When mating to the 9602/9602N RF connector use MMCX male connectors from SAMTEC part number MMCX-P-P-H-ST-TH1. This is a thru hole printed circuit mount connector with the correct mechanical spacing to allow the 9602/9602N to fit flush on the motherboard. Note - this 9602/9602N module has a different antenna connector than Iridium transceivers. Both RF connectors on the 9602/9602N module are intended for an inter-board connection to the host system motherboard and should not be directly connected to an external antenna cable or cable distribution system. Additional information can be found at: http://www.samtec.com 4.2 ANT Connector The main RF connector for the 9602/9602N is the antenna connector, labeled “ANT” in the board silkscreen. This provides the RF connection between the 9602/9602N module and the host system motherboard. Note that for safety reasons, both RF connectors on the 9602/9602N module are intended for an interboard connection to the host system motherboard and should not be directly connected to an external antenna cable or cable distribution system. The EN609502 compliance standard outlines that telecommunications equipment needs protection from a 2KV spike. The MMCX connectors are not capable of 2KV operations therefore protection needs to be provided on the developer’s motherboard and a larger connector needs to be used. Developers are encourages to review the EN609502 compliance standards for additional details. Iridium Communications Inc.

Table 11: Antenna Characteristics Parameter Impedance Gain Polarization VSWR (maximum operational) Value 50 Ohms nominal 3dBi RHCP 1.5 : 1 Note: • Existing qualified Iridium antennas may be used. (i.e. antennas designed for the 9601, 9522, 9522A and 9522B) • Existing antennas will require different RF connector types to than those for the 9601, 9522, 9522A and 9522B 4.3 GPS Connector The second RF connector, labeled “GPS” in the board silkscreen, is a pass-through connection from the antenna path and is provided for GPS receivers that wish to share the main antenna. An overview of this circuit is provided in Figure 7. The following operational points should be noted when using GPS receivers connected to this point. The GPS pass-through path is activated by detecting the presence of a DC voltage on the centerpin of the GPS connector. The 9602/9602N uses the voltage from the GPS center pin to switch on the RX path and requires minimal current (<100uA). The GPS path activated when this center-pin voltage is higher than 1.2V (9602) / 1.6V (9602N). There is a gain of approximately -3dB (9602) / +5.0dB (9602N) in the receive direction from ANT to GPS. The GPS receive path is temporarily switched off during transmissions from the 9602/9602N. As long as the 5V supply to the 9602/9602N is connected and the DC voltage on the GPS connector is present, the GPS pass-through path is made available. The GPS path is available even when the 9602/9602N module has been turned off using its ON/OFF control signal. If the GPS port is not used it may be left un-terminated with no adverse affect. The GPS receiver must present 50 ohm impedance across the Iridium band or SBD performance could be degraded. The output return loss is typically -8 dB. Iridium Communications Inc.

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. 4.6 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. The Test Interface Card (TIC board) implementation adds about 0.6 dB loss in the antenna path. 5. If the reading is near the decision threshold it would be easy to see a 1 bar difference Iridium Communications Inc.
