[T404] LSF Developer Guide for FW v3.x [T405] IsatData Pro Service API Reference for FW v3.x T407, VERSION 0.10 BETA © ORBCOMM PROPRIETARY ST 6000 - HARDWARE GUIDE 1 OVERVIEW The ST 6000 provides a high performance, low latency, two-way communication solution that uses the IsatData Pro network. The device consists of a Lua application controller, integral antennas, a satellite modem for communicating with the satellite, an integral GNSS subsystem, several input/output feeds capable of monitoring and controlling external sensors and devices, and dedicated serial ports (two RS-232 ports and an RS-485). Solution Providers (SPs) must create a custom power supply for their particular application. Figure 1: ST 6000 The ST 6000 is suitable for both industrial and fixed applications, and it can work as a standalone data-messaging device, with built-in I/O data collection and processing capabilities. Feature-rich software tools make programming easy and shorten the design and testing time. 1.1 Key Features and Benefits The ST 6000 has the following key features and benefits: Designed to be incorporated into a custom solution Built-in GNSS receiver to calculate position, speed, and heading that uses the satellite antenna Broad operational temperature range IsatData Pro message payload and latency capabilities T407, VERSION 0.10 BETA © ORBCOMM PROPRIETARY ST 6000 - HARDWARE GUIDE 2 COMPLIANCE Certification is pending for all the items below. CE Mark Norms EN 301 426 EN 301 489-20; EN 301 489-1 EN 60950 IEC 62311 FCC Regulations FCC ID: XGS-ST6000 47 CFR 25 47 CFR 15 OET 65 Industry Canada Regulations IC ID: 11881A-ST6000 ICES-003 RSS-170 RSS-102 Note: Integrators who integrate ST6000 OEM module into their final products should follow FCC and IC labeling rules to indicate the final product "CONTAINS FCC ID: XGS-ST6000 and IC ID: 1181A-ST6000" on product label. In some cases, If the regulation is applied, Integrators may need to get their own FCC ID and IC ID for the final product. Anatel Anatel certification and test results are available to Solution Providers for use as a baseline for the certification approval of their ST 6000 enclosure. In all cases, the SP is responsible for ensuring that their final ST 6000 enclosure complies with all local regulatory, electrical and safety codes. As the ST 6000 enclosure contains the SP's power supply and possibly other circuitry that affects the ST 6000, likely additional testing or a repeat of some of the tests listed below may be required.

Figure 4: Onboard Antennas 3.3 Power 3.3.1 Input Power The ST 6000 has two power input pins (VAUX and VIN), and can be powered from either a single or dual external DC power source. VAUX supplies power to the ST 6000 baseband and RF processors. Regulated power must be applied to this pin continuously to keep the device alive and synchronized with the satellite network. VIN is the input power pin for the RF power amplifier circuitry. Regulated power must be applied to this pin whenever the device drives the TX_PWR EN line high and may be removed when the TX_PWR EN line is low. Alternatively, power may be applied to this pin continuously and TX_PWR_EN ignored. Note: Input power protection is not provided on the ST 6000.

Refer to the pin number descriptions in section 3.1.5 for an explanation of each I/O signal. To connect these ports to an external device you may need to use a suitable translator depending on what the signal is connected to. The I/O electrical characteristics of this interface are shown in Table 7 and Table 8 shows the analog characteristics. Table 7: I/O Electrical Characteristics Parameter Min. Typ. Max.

Note: This does not imply that the software must have the capability of generating high rate pulse trains at frequencies > 10 Hz. 3.5 Serial Interfaces The ST 6000 is equipped with various serial ports. To connect these ports to a standard RS-232 serial device such as a computer for example, you must use a 3.3 V TTL/CMOS to RS-232 translator device.

The auxiliary port is primarily intended for debug output or software upgrade downloads. The console and auxiliary serial port is connected directly to the UART of the microcontroller and therefore communicates via CMOS level RS-232 style signaling (0-3.3 V, noninverted). The console and auxiliary serial interfaces to the ST 6000 are asynchronous with 1 start bit, 8 data bits, no parity, 1 stop bit; the default rate is 9600 bps, while the maximum rate is 115.2 kbps. The interfaces are 3.3 V TTL compatible. T407, VERSION 0.10 BETA © ORBCOMM PROPRIETARY 18 ST 6000 - HARDWARE GUIDE 3.5.2 RS-485/J1708 Interface The ST 6000 has a dedicated TTL level serial port for interfacing to an RS-485/J1708 interface as an accessory bus and for SCADA interfacing. The ST 6000 does not incorporate a driver and termination resistor. The RS-485 serial port is connected directly to the UART of the microcontroller and therefore communicates via 3.3 V CMOS levels. 3.6 Accelerometer/GNSS/Temperature Sensor The ST 6000 supports an accelerometer, a multi-GNSS module, and a temperature sensor.

In powered devices where low power is not critical, GPS can be polled to detect motion. However, for low power applications frequent GPS fixes can dominate the power budget. To reduce power budget effects of GPS fixes, an accelerometer can be used to trigger a GPS fix to detect if motion occurred. The accelerometer thresholds to detect motion vary depending on the environment. In order to avoid, false motion detects, extensive testing is required to ensure that adequate acceleration magnitude thresholds and time durations are used. Refer to [T405] for further details about the accelerometer. Table 11: Accelerometer Specifications Parameter Condition Resolution 2g 3.91 mG software selectable ±2 ±4 ±8 ±16 1000 Hz Tracking Min.

T407, VERSION 0.10 BETA © ORBCOMM PROPRIETARY 24 ST 6000 - HARDWARE GUIDE 4 INTEGRATION GUIDELINES This section contains a number of guidelines to assist the Solution Provider (SP) in building their ST 6000 enclosure. It must be recognized that this section provides guidelines only and each SP must use their own discretion to finalize the integration approach that works for them. 4.1 Enclosure Design The ST 6000 is not designed for outdoor environments. Consequently, the ST 6000 requires a robust environmentally sealed enclosure that can house the ST 6000. The following guidelines are recommended for the enclosure design. An IP67 rating or better for outdoor use. Use enclosure materials that are transparent to L-Band (1-2 GHz) radio signals. Two recommended enclosure materials are: Xenoy® Resin 5220U. This plastic material offers good chemical and UV resistance and great impact resistance even at low temperatures. Lexan EXL 9330. 4.2 Ground Plane Requirements A metal plate is required under the antenna board. The optimal recommended separation between the metal plate and the modem card is 0.86”. This can be reduced to 0.5” with some moderate impact on low elevation gain. If the ST 6000 is installed on a metal surface larger than the metal plate size indicated in Figure 9, then no metal plate is needed as long as the surface-to-antenna distance is the same as shown in Figure 9. T407, VERSION 0.10 BETA © ORBCOMM PROPRIETARY 25 ST 6000 - HARDWARE GUIDE Figure 9: Ground Plane Requirements (in.) 4.3 Labeling The mobile ID on the ST 6000 is the network identification number. It is recommended that the SP place a copy of the mobile ID on the exterior of the enclosure housing the device. With the mobile ID on the enclosure, installers can readily identify the network identification number. T407, VERSION 0.10 BETA © ORBCOMM PROPRIETARY 26
