Product Description

Overview
This User Guide is intended to be a user manual for the Industrial GPS Asset Tracker, henceforth referred to as the Tracker for brevity, developed by TEKTELIC Communications Inc.
The Tracker is a multi-purpose LoRaWAN IoT asset tracker intended to allow assets to be located via a LoRaWAN network. The location is obtained from a GNSS receiver. The Tracker is equipped with an IoT targeted MCU that has Bluetooth compatibility, a LoRa-based radio, a GNSS device, an accelerometer, and three battery gauges. Table 1-1-1 presents the available Tracker model.

Installation

Included Product and Installation Material
The following items are shipped with each Tracker:

• Industrial GPS Asset Tracker in a ruggedized IP67 polycarbonate enclosure with D-cell LTC batteries installed
• Magnet to wake up the Tracker from DEEP SLEEP (activate the Tracker)

Safety Precautions
The following safety precautions should be observed:

• Use only LTC cells.
• Should the Tracker be opened and powered externally, do not exceed the maximum specified terminal voltages.
• All installation practices must be in accordance with the local and national electrical codes.

Unpacking and Inspection
The following should be considered during the unpacking of a new Tracker:

• Inspect the shipping carton and report any significant damage to TEKTELIC.
• Unpacking should be conducted in a clean and dry location.
• Do not discard the shipping box or inserts as they will be required if a unit is returned for repair or re-configuration.

Commissioning and Activation
The Tracker is shipped in closed enclosure with the batteries installed and engaged. However, the Tracker is in a state of DEEP SLEEP where it draws infinitesimal current, until it is woken up (activated) by the provided magnet1.

The Tracker does not need to get opened for activation. Assuming that the Tracker has been commissioned on the NS, use the magnet to wake up the Tracker as illustrated in Figure 2-1. A magnet presence is achieved by attaching the magnet to the enclosure at the magnet sign. A magnet absence is achieved by taking the magnet at least 2 cm away from the enclosure.
Here are the steps as illustrated in Figure 2-1:

1. Attach the magnet, then take it away, then attach it back again, all at a normal pace.
2. Keep magnet attached to the enclosure at the magnet sign for at least 3 sec but less than 10 sec.

As soon as the specified magnetic pattern is applied to the Tracker, the Tracker is reset and tries to join the network. See section 4.3 for the expected LED behaviour of the Tracker during the join process. It may take about 10-15 sec from the Tracker reset to seeing the LED activity showing join attempts.
Note that the specified magnetic pattern always triggers a module reset, even during normal operation. Such a reset also activates an already in-DEEP- SLEEP module.

The Tracker can be put into DEEP SLEEP at anytime by opening it up and pressing the internal sleep button labeled as SW2 and located visibly on top of the Tracker PCBA. If put to DEEP SLEEP, the Tracker can be woken up (activated) again using the same procedure explained above, i.e. by the use of the magnet. Removing and reinserting the batteries can also activate the Tracker.
Note: Replacing the batteries of the Tracker does not cause the Tracker to go to DEEP SLEEP. As soon as new batteries are inserted, the Tracker boots up and tries to join a LoRaWAN.

Mounting
On either side of the enclosure there are two mounting holes, see Figure 2-2. These mounting holes can be used to screw the enclosure to a solid surface. The mounting holes are T-shaped slots so the device can be secured with ropes, zip ties or screws depending on the user’s needs. The recommended mounting screw size is M3. Mounting screws are not provided with the Tracker.

The mounting surface must be capable of holding > 2 kg (4.5 lbs).

Battery Replacement
Open up the Tracker using a #2 Phillips screwdriver. The Tracker has 12x enclosure Philips screws at the bottom. Be careful not to misplace the silicone cover gasket.
Replace the battery(-ies). The Tracker accepts D-size, 3.6 V, LTC batteries. The Tracker can operate with one or two batteries. One battery yields half the capacity of a two-battery module. In the case of one battery, the battery can be inserted in any of the two battery holders. Suggested replacement batteries include,

• Tadiran TL-4930/S or TL-5930/S
• Xeno Energy XL-205F STD
• Saft LS33600

Once the Tracker is powered and tries to join (see Section 3.3 for LED behavior), replace the cover and gasket. Make sure that the gasket is properly seated in the cover before placing on the Tracker housing. Tighten the 12 cover screws to 2.5 lbf-in (30 N-cm).

Operation, Alarms, and Management

Configuration
The Tracker supports a full range of OTA configuration options. Specific technical details are available in the Tracker TRM. All configuration commands need to be sent OTA during a Tracker’s DL windows.

Default Configuration
The default configuration on the Tracker is:

• Report the battery voltages once every day.
• Report UTC and GNSS position fix coordinates once every hour.
• Scan and report up to 8 discovered BLE devices with the largest RSSIs once every 6 hours.
• Report the battery voltages when the magnetic switch is triggered 3 times in 3 sec.

LED Behaviour
See Figure 1-1 for the location and identification of the Tracker LEDs. During the boot and join process:

• Both LEDs will come on briefly when power is first applied.
• After a small delay (< 1 second) the LEDs will turn off and one of them will blink briefly.
  • If the System (green) LED blinks, then all health checks on the board have passed.
  • If the LoRa (red) LED blinks, then one of the health checks has failed. Consider replacing the batteries, or moving the Tracker to an environment within the temperature range.
• Immediately after the delay, the join procedure will begin. During this time the System LED blinks for 1 sec every 10 sec until the Tracker joins a network.
• During normal operation, the LoRa LED blinks whenever LoRa activity occurs on the Tracker (transmitting or receiving packets).

Activation, Putting to DEEP SLEEP, Resetting, and Shutting Down
Table 3-1 shows how to activate, put to DEEP SLEEP, reset, or completely turn off the Tracker.

Table 3-1: How to Activate, Put to DEEP SLEEP, Reset, or Shut Down Tracker

• Apply the specified magnetic pattern described in Section 2.4 to the Tracker (no need to open the Tracker)
  OR:

• Remove and reinsert the batteries

• Apply the specified magnetic pattern described in Section 2.4 to the Tracker (no need to open the Tracker)
  OR:

• Remove and reinsert the batteries

Completely power off| Remove the batteries

NOTE: Shutting down or resetting the Tracker will cause all unsaved user configurations to be lost. Save your desired configuration to the Tracker flash before powering off, putting to DEEP SLEEP, or resetting the Tracker.
