T401, Version .15 viii © ORBCOMM Proprietary OGi Modem - Hardware Guide 1 Overview The OGi modem is an L-Band mobile device and provides either an AT interface or an OG interface for command and control. Hardware using an AT interface operates on the IsatData Pro gateway while hardware using an OG interface operates on the ORBCOMM gateway. ORBCOMM’s turn-key OEM solutions are intended for early integration into M2M applications. An OGi modem contains a satellite transceiver and a GNSS receiver, and requires a specific passive antenna. The modem accepts commands and returns responses via a serial interface. The modem is suitable for both industrial and fixed applications such as: Transportation and Distribution Fleet management and security Asset tracking, monitoring and control 1.1 Overview of the Messaging System The IsatData Pro service allows OEM Integrators to offer particular applications and/or services to their clients. As shown in Figure 1, the OEM Integrator communicates with the modem through a centralized gateway. The gateway is the communications hub of the system, controlling access to the modem and routing traffic to the modem, regardless of where it is deployed in the world. Figure 1 Messaging Gateway Satellite GPS Satellites Internet Solution Provider and Customer Site Land Earth Station (LES) Gateway OGi Modem Computer Configuration and data retrieval from the modem can be easily accomplished through Internet-based application services provided by OEM Integrators or by integrating existing customer enterprise software to receive information from the Gateway. IsatData Pro provides the following key features and benefits: Two-way communication Messaging to a host connected to the modem © ORBCOMM Proprietary T401, Version .15 OGi Modem - Hardware Guide Broadcast messages Low latency messaging Up to 6,400 bytes from-mobile messages for the AT Interface; up to 6,000 bytes from-mobile messages for the OG Interface Up to 10,000 bytes to-mobile messages for the AT Interface; to-mobile messages for the OG Interface are truncated Acknowledged messages Global service 1.2 OGi Modem The OGi modem provides easy integration and the highest level of EMI/EMC shielding that reduces integration risk when the modem is co-located with other electronics. Figure 2 OGi Modem 1.2.1 Remote Antennas Two passive antenna types are available: a standard antenna (Figure 3) and a low elevation antenna (Figure 3). The standard antenna has an elevation angle of 20 to 90° and the low elevation antenna has an elevation angle of -15 to 90°. The OEM Integrator is responsible for providing a specific RF cable to connect the antenna to the modem. Both the standard and low elevation antennas are: Available with a side or bottom connector Sealed for operating in outdoor environments Provide four mounting tabs for installation Available with an SMA connector Available packaged or unpackaged T401, Version .15 10 © ORBCOMM Proprietary OGi Modem - Hardware Guide Figure 3 Antennas Low Elevation Antenna Standard Antenna Figure 4 Antenna Bottom Mount (standard antenna shown) 1.2.2 Unpackaged Antennas Both antenna types, standard and low elevation, are also available in an unpackaged form. Both feature an IPX connector for connection to the modem and four mounting holes for installation.

The modem operating modes are described in Table 1. Table 1 Operating Mode Transmit Mode Receive Mode Satellite Modem Operating Modes Description In transmit mode the modem is transmitting a signal to the gateway. In receive mode the modem is attempting or actively listening to the satellite (listening on the bulletin board channel or on a traffic channel). 1.4.2 GNSS Receiver The GNSS receiver is a module peripheral that is either on or off. T401, Version .15 12 © ORBCOMM Proprietary OGi Modem - Hardware Guide 2 Compliance At this time, all certifications listed in this section are pending for the OGi modems. Once approved, these certifications and test results will be available to OEM Integrators for use as a baseline for the certification approval of their enclosure. However, the OEM Integrator is responsible for ensuring that their final enclosure complies with all local regulatory requirements, and electrical and safety codes wherever the enclosures are sold or used. As the OEM Integrator’s enclosure contains the OEM Integrator’s power supply and possibly other circuitry that affects the modem, the OEM Integrator most likely needs to perform additional testing or repeat some of the tests listed below.

The mobile ID is a 15-digit alphanumeric identifier in the format NNNNNNNNSKYXXXX. Figure 20 shows the location of label. Figure 20 Mobile ID Location Mobile ID T401, Version .15 28 © ORBCOMM Proprietary OGi Modem - Hardware Guide 4 Integration Guidelines This section contains a number of guidelines to assist the OEM Integrator in building their enclosure. It must be recognized that this section provides guidelines only and each OEM Integrator must use their own discretion to finish the integration approach that works for them. 4.1 Regulatory Guidelines The OEM Integrator must recognize the importance of regulatory requirements for their integrated design. These requirements can have a major impact on the product design functioning and schedule. Further, as the regulatory requirements can be quite complex, ORBCOMM recommends that OEM Integrators always seek the advice of a regulatory expert prior to starting integration. This advice allows the OEM Integrator to properly plan and schedule design and test requirements. When the regulatory tests are defined, it is also important to identify authorized test labs that are qualified to perform the required tests. Prior to a design, critical tests should be identified. It is recommended that the OEM Integrator pretest any high risk critical specifications early in the design stage. 4.2 Compliance Refer to section 2 for compliance information. 4.2.1 Reference Power Supply The internal power supply operates between 5.0 and 15.0 VDC. A full RF output requires an input voltage above the minimum operating voltage. 4.2.2 Review Process The OGi modem integration can be challenging as the modem is a sensitive receiver that has stringent emission specifications. To help minimize integration risk, ORBCOMM recommends that the OEM Integrator consult with ORBCOMM and review the mechanical integration prior to starting a detailed design. 4.3 EMI/EMC Guidelines The modem and antenna form a highly sensitive receiver that can receive very weak satellite or GNSS signals. The highly sensitive receiver can also pick up noise or other interference. Components such as processors and support circuitry should be shielded with good quality shielding. It is also recommended that RF coupling/bypass capacitors be added to the power supply rail, as close as possible to the modem's power pin. Digital interface devices should be shielded, and care must be taken to ensure the digital interface cable does not run close to the antenna. © ORBCOMM Proprietary 29 T401, Version .15 OGi Modem - Hardware Guide 4.3.1 Typical Integration The modem is intended to be used in a larger system. The system must provide adequate power (low noise and relatively high current) and must possess an electrical signaling mechanism compatible with the modem. Ensure that the custom designed circuit board does not create undesirable signals that can impact the performance of the modem. An external antenna is required to complete the modem design. Figure 21 Typical OEM Integrator Modem Design 4.3.2 Antenna Cable Guidelines The OEM Integrator is responsible for designing a custom-made RF cable to connect antenna and modem. The following recommendations provide some guidelines for RF cable selection: Application Cable Type Connector Packaged/Remote Antenna cable Unpackaged Antenna Cable RF Coaxial 50 Ω RF Coaxial 50 Ω MMCX male/SMA male MMCX male/IPEX plug male Max. Total Loss at 1.6 GHz 1.5 dB Cable Example 0.5 dB LMR195 4.3.2.1 General Guidelines for Antenna Positioning Antenna placement is important. When positioning the antenna consider EMI performance of the integration product and visibility to the sky. Depending on the EMI performance of the integration product, the satellite antenna may need to be paced a distance away from the integration product. The antenna must be positioned such that it has a good view of the sky and there is no metal/circuit board nearby to interfere with or block the antenna. 4.3.3 Host Shielding In a typical integration, the modem is controlled by microcontroller. The microcontroller and supporting circuitry, such as memory, high speed data/address bus, clock references and power supply sources are normally noisy and could potentially T401, Version .15 30 © ORBCOMM Proprietary OGi Modem - Hardware Guide affect the highly sensitive satellite or GPS receiver performance if the antenna is placed too close to the circuitry. The following guidelines are provided when building a microcontroller using the modem. Microcontroller and circuitry should be fully shielded. Digital interfaces such as serial ports, USBs and I2C along with their tracks should be shielded. Avoid running any digital interface connector and cable close to the antenna. Do not route any metal or cable above the ground plane of the antenna card or above the antenna. 4.3.4 Decoupling The following are recommendations for the power supply and digital lines to reduce emissions that could be picked up by the modem. RF decoupling/bypass capacitors (22pF 0403 or 33pF 0603 typical) be added as close as possible to the modem's power pin on the power supply rail of the processor and high speed digital circuitry. RF decoupling/bypass capacitors added on the interface power rails. 4.4 Maximum Current It is recommended that the power supply be designed with a margin to supply the maximum current required by the modem. Refer to sections 3.4.1 and 3.4.2 for maximum current and inrush current requirements when designing a power supply. 4.5 Enclosure Design The modem is not designed for outdoor environments. Consequently, the enclosure typically requires a robust environmentally sealed enclosure that can house the modem. The following guidelines are recommended for the enclosure design. An IP67 rating5 or better for outdoor use. Use enclosure materials that are transparent to L-Band (1-2 GHz) radio signals. Lexan Resin EXL 9330 is a common recommended enclosure material, but there are many other suitable materials. The unpackaged standard antenna is supplied with a dielectric cap, a piece of plastic over the ceramic patch antenna that helps to negate the effects of different enclosure materials on the performance of the antenna. With the dielectric cap, the standard unpackaged antenna can be placed as close as desired to the adjacent enclosure material. The unpackaged low elevation antenna is less sensitive to enclosure material selection and does not require a dielectric cap. IEC 60529 © ORBCOMM Proprietary 31 T401, Version .15 OGi Modem - Hardware Guide Do not use metallic paint or tinting that may be conductive. 4.5.1 Label Guidelines The label on the modem includes its mobile ID. If the modem is placed inside of an enclosure that is not intended to be opened, an exterior label must be affixed to the enclosure, in a visible location. When integrating the modem into an enclosure, you must do one of the following: Provide visibility of the modem through a window. Provide an easy way to get to the modem when an access panel or door is removed. Place a label on the outside of the final enclosure that contains the following information: A copy of the ORBCOMM logo Text that indicates the enclosure contains a transmitter The mobile ID A list of all valid certifications (for example, ETSI, Industry Canada, etc.) With this information on the enclosure, installers can readily identify the required information. 4.5.2 Mating Connector Guidelines Refer to section 3.1 for connector guidelines. 4.6 Modem Mounting Guidelines As shown in Figure 22 the modem has a hole in each corner of the enclosure sized for M2.5 hardware to secure the modem to an application card or other environmental enclosure surface. Figure 22 Modem Mounting Holes Screw holes (2) Mate with a Mini PCI Express Connector T401, Version .15 32 © ORBCOMM Proprietary OGi Modem - Hardware Guide MMCX Connector The modem inserts into the connector at an angle, and is held in place with screws and standoffs that match the connector height. The standoffs and screws generally interface to a ground connection on the host board. Mounting screws should be properly tightened to 0.80 N-m (7 pound-inches) of torque or as per the specifications of the connector Manufacturer. 4.7 Unpackaged Antenna Mounting Guidelines As shown in Figure 17 the unpackaged antenna has a set of four holes sized for M3.5 hardware to secure the antenna to an environmental enclosure surface. A second set of holes at the corner of the card can be used for mounting with #4 hardware, but the holes are tight fitting and tolerances need to be considered, so SkyWave recommends the larger hole set for mounting. © ORBCOMM Proprietary 33 T401, Version .15 OGi Modem - Hardware Guide 5 Antenna Installation The following section contains ORBCOMM's recommended installation guidelines for installing the antenna. It is recommended that the OEM Integrator include these in the installation guidelines for end users. 5.1 Antenna Mounting Guidelines CAUTION Mount the antenna at least 20 cm away from humans. The following guidelines for mounting the remote antenna also apply to an OEM Product that includes the unpackaged antenna where applicable. For fixed installations ensure that the antenna is pointing toward the equator, facing south if in the Northern Hemisphere and facing north if in the Southern Hemisphere, and its line of sight to the sky (satellite) is clear of obstructions. For a mobile installation, mount the antenna at the highest point on the vehicle or vessel where it has a clear view of the sky (satellite) in all directions. Do not mount the antenna near metal objects. The antenna can communicate with the satellite through fiberglass, but not through metal. Metal causes interference if it is above the antenna and within 10.2 cm from the top of the antenna. Respect the 20° or -15° elevation angle requirement with metallic object. Ensure that the antenna is at least 1.3 cm higher than the metallic surface in cases where it must be mounted next to a vertical metallic surface. Ensure that any paint above the antenna is non-metallic and non-metallic flake, if the installation is under fiberglass or composite wind fairings. Mount the antenna on a surface that does not exceed the antenna's maximum operating temperature. Locating the antenna where temperatures exceed the recommended range might compromise performance. Do not mount the antenna close to an exhaust pipe due to the excessive heat and the potential for the exhaust pipe causing satellite blockage. Do not mount the antenna close to air horns or any tractor roof hardware (for example, emergency lights) that could interfere with satellite communications. Mount the antenna on the driver's side of the vehicle, if possible, when there is a possibility of strikes by overhanging tree branches. Do not drill any holes before checking that you have room for the bend radius of the low loss coax cable. For reliable operation, do not go below a bend radius of 1.3 cm. Measure the bend radius of the cable as shown in Figure 23. T401, Version .15 34 © ORBCOMM Proprietary OGi Modem - Hardware Guide Figure 23 Antenna Cable Bend Radius Bend Radius (Minimum 1.3 cm) Correct Mount on a surface that is free from dirt, grime, water and grease to avoid damaging the mounting surface or the vehicle’s paint. Mount so that the cable end faces the rear of the vehicle. 5.2 Mount a Remote Antenna Two mounting options are available for the remote packaged satellite antennas: screw mount or silicone mount. OEM Integrators, who have included an unpackaged antenna within their product, should apply any packaged antenna restrictions mentioned in this section, to the mounting of their own product. 5.2.1 Screw Mount If mounting a remote antenna the following tools and materials are required: Drill M4 hardware Outdoor waterproof adhesive sealant (silicone) To mount the antenna, follow the steps below. 1. Find a location for the remote antenna following the guidelines provided in Section 5.1. 2. Use the mounting template (APPENDIX A) or the antenna as a template, to mark the location of the mounting holes. CAUTION Cable management and connector strain relief MUST be incorporated in the installation. Secure the cable no more than 15 cm from the antenna enclosure and at regular intervals along its length as part of the installation to prevent cable wear and eliminate strain on the terminal connector. Damage to the terminal connector interface or cable might otherwise result leading to hardware failure. 3. Drill the mounting holes using the drill. 4. Apply waterproof sealing compound, such as RTV silicone, around the drill holes so water does not seep into the asset. © ORBCOMM Proprietary 35 T401, Version .15 OGi Modem - Hardware Guide CAUTION Adhesive or silicone cannot block the air vent features shown in Figure 24. Figure 24 Air Vent Feature Do Not Block These Features 5. Secure the antenna in place with self-tapping screws or machine screws and nuts depending on access to the mounting surface. The remote antenna might also be mounted using adhesive or a high strength outdoor grade silicone when mounting holes are not an option in the mounting surface. Note: The recommended torque specification is approximately finger tight plus a 45 degree rotation using an 8 mm wrench. CAUTION Cable management and connector strain relief MUST be incorporated in the installation. Secure the cable no more than 15 cm from the enclosure and at regular intervals along its length as part of the installation to prevent cable wear and eliminate strain on the terminal connector. Damage to the connector interface or cable might otherwise result leading to hardware failure. 5.2.2 Adhesive Mount The remote antenna might also be mounted using adhesive or a high strength outdoor grade silicone when mounting holes are not an option in the mounting surface. Refer to the adhesive manufacturer's recommendations for application temperature, application conditions, compatible bonding materials, and minimum curing times when working with an adhesive. Failure to follow the manufacturer's guidelines could result in the remote antenna separating from the mounting surface. CAUTION T401, Version .15 Adhesive or silicone cannot block the air vent features shown in Figure 25. 36 © ORBCOMM Proprietary OGi Modem - Hardware Guide Figure 25 Air Vent Feature Do Not Block These Features 5.2.2.1 Silicone Side Connector Mount The following tools and materials are required if mounting a side cabled remote antenna with silicone. Outdoor rated silicone adhesive sealant (GE RTV 108) Isopropyl alcohol or an equivalent To mount the antenna: 1. Find a location for the remote antenna following the guidelines provided in Section 5.1. 2. Clean the asset surface with isopropyl alcohol or an equivalent product that does not leave a residue. 3. Apply silicone around the hole in the asset and to the bottom surface of the remote antenna and position onto the assets surface. 4. Apply a generous bead of silicone around the entire perimeter of the remote antenna enclosure. The two vertical slots shown in Figure 26 are vent features and must not be filled with silicone. Figure 26 Apply Silicone to Remote Antenna Do Not Block These Features © ORBCOMM Proprietary 37 T401, Version .15 OGi Modem - Hardware Guide 5. Place some weight on the remote antenna while the silicone cures. CAUTION Cable management and connector strain relief MUST be incorporated in the installation. Secure the cable no more than 15 cm from the antenna enclosure and at regular intervals along its length as part of the installation to prevent cable wear and eliminate strain on the terminal connector. Damage to the terminal connector interface or cable might otherwise result leading to hardware failure. 5.2.2.2 Silicone Bottom Connector Mount The following tools and materials are required if mounting a remote bottom connector antenna with silicone. Outdoor rated silicone adhesive sealant (GE RTV 108) 5/16” or 8 mm wrench Drill 12 to 19 mm drill bit for a straight SMA cable connector 29 mm minimum drill bit (hole saw) for right angle SMA cable connector Isopropyl alcohol or an equivalent To mount the antenna: 1. Find a location for the remote antenna following the guidelines provided in Section 5.1. 2. Drill a 12 to 19 mm hole in the asset surface (Figure 27) when using a straight SMA cable connector. For a right angle SMA cable connector, drill a minimum hole diameter of 29 mm. Refer to the note in step 7 if the right angle hole is considered too large. Figure 27 Drill Mounting Hole 3. Clean the asset surface with isopropyl alcohol or an equivalent product that does not leave a residue. 4. Insert the cable through the hole, from inside the asset, and thread the cable connector onto the antenna. Torque the connector finger tight plus a 45 degree rotation using an 8 mm wrench. T401, Version .15 38 © ORBCOMM Proprietary OGi Modem - Hardware Guide Figure 28 Attach Cable to Antenna 5. Apply silicone around the hole in the asset and to the bottom surface of the remote antenna. Figure 29 Apply Silicone to Hole in Asset 6. Lower the remote antenna onto the mounting surface. The straight SMA cable connector can be lowered straight down onto the mounting surface. The right angle SMA cable connector, not shown, must be pivoted down onto the mounting surface to fit the right angle cable and connector through a larger clearance hole. Additional care is required with this installation to ensure the right angle cable and connector does not smear the silicone around the clearance hole when attempting to pivot the antenna into position. 7. Apply a generous bead of silicone around the entire perimeter of the remote antenna enclosure. The two vertical slots shown in Figure 26 are vent features and must not be filled with silicone. Note: If the large clearance hole required for the right angle SMA cable connector is considered too large, you have the option to use a smaller clearance hole in the mounting surface and install the cable from inside the asset after the antenna has been adhered with silicone. © ORBCOMM Proprietary 39 T401, Version .15 OGi Modem - Hardware Guide In this case, first confirm there is enough room from inside the asset to thread the SMA cable connector by hand and clearance for the wrench to apply the final torque. Also note that the silicone used to mount the antenna must be fully cured before the cable can be installed from the inside otherwise the seal and mounting are compromised. Figure 30 Apply Silicone to Terminal Do Not Block These Features 8. Place some weight on the remote antenna while the silicone cures. CAUTION T401, Version .15 Cable management and connector strain relief MUST be incorporated in the installation. Secure the cable no more than 15 cm from the antenna enclosure and at regular intervals along its length as part of the installation to prevent cable wear and eliminate strain on the terminal connector.
