  • Page 5: Purpose

    When a data terminal equipment (DTE) is connected to the 9602-LP with SatTerm software installed (or any terminal emulator software), the DTE can be used to setup the operating parameters of the 9602-LP via a serial connection. A DTE can be a desktop computer, a laptop computer or a PDA.
  • Page 6 DC power supply. Users must take into account voltage drop across the power supply cable to ensure adequate current provided to the 9602-LP during SBD sessions. If input voltage does not stay above 3.0VDC during surge or high current demand, the 9602- LP will reset itself.

    One of the limits may be exceeded but not both As long as power is provided to the 9602-LP, the GPS receiver will store ephemeris data in its memory before powering down (sleep between reports). The ephemeris data are valid up to two hours and can be used in future startup to improve time-to-first-fix.
  • Page 9 THE JUMPER. The jumper can be found by removing the modem’s top plate. With the 9602-LP held in the position shown in Figure 2 (DB15 connector to the left), the 9602-LP is set for 3.6VDC to +5.3VDC when the red jumper is on the middle and top pins and is set for +6.0VDC to +32VDC when the jumper is on the middle and bottom pins.
  • Page 10 9602-LP. 4.3 TTL/CMOS Inputs/Outputs The 9602-LP has four TTL/CMOS inputs and three TTL/CMOS outputs. All I/Os are brought out to the multi-interface connector. SatTerm should be used to configure these I/Os as shown in Figure 3 under the I/O tab.

  • Page 11: Configuration Settings

    5.0 CONFIGURATION SETTINGS 5.1 Modes of Operation The 9602-LP can be in one of two operating modes at power up: (1) Command mode, or (2) Tracking mode. When in Command mode, AT commands can be entered to configure the 9602-LP’s operating profiles or the 9602-LP can be operated as a 9602-G (standard SBD-modem with GPS).
  • Page 12 Figure 4. Different Operating Modes of the 9602-LP. Normal Tracking Mode Normal Tracking is the mode when the 9602-LP is configured to power up with AT^START1 command or after transitioning from Command mode to Tracking mode with the AT^TRK command. Normal Tracking offers a wide range of unique settings as shown in Figure 5.
  • Page 13 9602-LP’s operating profile to be re-configured remotely in real-time. Since the Iridium RF board is ON at all times, the 9602-LP will consume the most power in between reports (~110mA at 5VDC). The GPS receiver can be left either ON or OFF in between reports to reduce power by ~40mA at 5VDC.
  • Page 14 DC converters and serial interfaces. The only active components are the microcontroller and the motion sensor. The 9602-LP will draw the lowest current in between reports of around 60A at 5VDC. The 9602-LP will not respond to any entered commands including the +++. The +++ command will work only while the tracker is waiting for GPS acquisition or is transmitting a report.
  • Page 15 When in motion, the sensor produces continuous on-off contact closures (a series of TTL level logic or pulse train) as it chatters open and closed. The signal level is fed directly into the 9602-LP’s micro- controller. When at rest, it normally settles in a closed state.
  • Page 16 (Yes)” and “Callable (No)” configurations. When in motion the 9602-LP uses a set of “Callable (Yes)” parameters to send GPS reports and when not in motion the 9602-LP uses a set of “Callable (No)” parameters to send GPS reports. The goal is to allow users the flexibility to define different set of parameters for different operating conditions.
  • Page 17 Normal Tracking. The Emergency GPS reports have a special data bit activated to alert the recipient of the message type. The 9602-LP allows GPS reports to be saved on its non-volatile memory when an Iridium satellite is not available.
  • Page 18 The Miscellaneous tab offers four settings. “Remote Update Password” sets the required password when a remote update to the current active operating profile is made from a command center while the 9602-LP is in the field. The <password> entered must be 8 characters in length and all printable characters are allowed.
  • Page 19 Using AT command ^IPS, the 9602-LP can also be set to power up by pressing the power button when DC power is first applied to pin 1 or pine 9. If the device is sleeping in between reporting cycles, pressing the power button will turn the 9602-LP on for 10 seconds.
  • Page 20 Gateway or if a message received from the Gateway contains an error(s). The LED blinks only after the 9602-LP is powered up with the last SBD session having an error but the next SBD session is error-free.
  • Page 21 “Remote Message Format” sets format of the messages that will be sent to the command center. “GPS Always ON” forces the GPS receiver to stay on in between reports allowing hot-start each time the 9602-LP wakes up. “Start-Up Mode” sets the power-up mode of the 9602-LP.

  • Page 22: Motion Sensor

    The 9602-LP has a built-in sensor that can reliably detect motion. It is truly an omni-directional movement sensor and will function regardless of how the 9602-LP is mounted or aligned. It is sensitive to both tilt (static acceleration) and vibration (dynamic acceleration). The sensor produces a series of TTL level logic or pulse train.

    2dB at the operating frequency of 1616 to 1626.5 MHz. NAL Research offers several types of antennas for use with the 9602-LP. These antennas include the fixed mast, mobile magnetic/permanent mount and portable auxiliary. For low-cost and applications where small form-factor and light-weight are required, NAL Research highly recommends model SYN7391-C as shown in Figure 15.

All the plots above show that the 9602-LP is more efficient (consumes less power) when operates in the 3.6VDC to 5.3VDC input range especially in between reports. It should be noted that the actual current profiles may vary for a number of reasons and users are again reminded to optimize their setup to attain the lowest possible power consumption.
