Hardware setup

Now that you have all your tracker hardware, follow the instructions on this page to prepare and connect all your tracker hardware. Use the Contents Menu to navigate around this page.

Overview

This is how your tracker hardware should be connected. Completed the steps in the sections below.

Step 1- Power Supply

The first part you will prepare for your tracker is the power supply which is based upon the ATX PSU. These PSUs are not immediately compatible with the tracker hardware so you will need to prepare some male barrel jack connectors for the Jetson, camera, ethernet switch, and add a master on/off switch.

Before proceeding, note that you could purchase an ATX breakout board such as the following which would avoid the need to cut wires off the ATX connector.

Double check the voltages on all hardware labels before preparing the barrel jacks.

  1. For items requiring 5v (e.g. Nano), cut a red and black wire from the ATX connector and attach to the correct screw terminals of a barrel jack (i.e. red +, black -).

  2. For items requiring 12v (e.g. Xavier, Camera), cut a yellow wire and black wire and attach to the correct terminals of another male barrel jack (yellow +, black -). This will gives a 12v connector.

  3. Finally, cut the green wire and a black wire and screw to the terminals of the SPST toggle switch. This will be a master power on/off for your tracker.

Keep in mind safety - the PSU should be unplugged. Also be aware you are likely voiding your PSU warranty.

Step 2 - Jetson

If you have chosen the Jetson nano, you will need to secure the Noctua fan to the Jetson using the following steps. However, if you have either the Xavier NX or AGX you do not need do this as they have integrated fans.

  1. Place fan on top of the Nano's heatsink. Orient fan so that the airflow blows away from the heatsink (see diagram on fan ). This will work with the PSU fan in the enclosure.

  2. Secure fan to heatsink using the 4 rubber strips provided (these work as vibration dampers). You could use 4 nylon cable ties for a temporary fix. We recommend you don't use screws.

  3. Plug fan into Jetson board using the 4 pin connector

Step 3 - GPS

Next, attach the Adafruit GPS.

  1. Connect the USB Micro-B adaptor to the Ultimate GPS and plug USB-A into a spare port on your Jetson device.

  2. If using the optional external GPS antenna, clip the uFL connecto to the GPS board then attach the antenna as shown below.

The ultimate GPS has a mount for CR1220 3v battery which helps the unit maintain it's state if/when the tracker is powered down [optional but recommended]. The mount will need to be soldered to the bottom of the board.

Step 4 - Storage

Jetson Nano

Plug the USB3 storage into a spare USB port on the Jetson

Jetson Xavier NX and AGX

Clip the NVMe drive to the Xavier e.g. as shown here https://www.youtube.com/watch?v=ZK5FYhoJqIg

Step 5 - Camera setup

Next, power on your camera and connect to your network. Follow the camera initialization according to the manufacturer's instructions and set a username and password.

It’s recommended that you assign a static IP address for the camera which you should be able to do from your router settings page.

With a Dahua camera you can adjust the following settings for video, conditions and profile

Video
Conditions
Profile
NTP
Video
  • Set Encode Mode to H.265. H264H cannot be used because Flexible Macroblock Ordering is not supported by our video decoder.

  • Disable the sub stream

  • Disable the watermark

  • Change Bit Rate Type to VBR

  • In the overlay tab it's possible to put the tracker name on the video as origin

Conditions

  • In night mode switch to b/w and raise the gain a bit and adjust to the local lightnoise

  • Turn off the IR mode

  • Day - Anti-Flicker Outdoor, Mode Auto, 3DR On 60

  • Night - Anti-Flicker Outdoor, Mode Manual, Shutter 1/3, Gain 0-100, 3DR On 60

Profile

Set day and night mode transition times in the schedule UI e.g.

NTP

Check the NTP checkbox and enter your Tracker IP address (you will need to return to do this after completing the setup).

Step 6 - Micro SD

With the hardware setup complete, it's now time to install the Ubuntu operating system on your micro SD card. You will need to use another computer to do this. Follow the Nvidia Instructions for flashing the Ubuntu 18.04 Jetson image to the card:

  • Download Nano Jetpack 4.4 image here, then follow the instructions from step 2 here

  • Download Jetpack 4.4 NX image here, then follow the instructions from step 2 here

  • Xavier AGX (image comes preinstalled)

After that is complete (~10 mins), insert the SD into the SD slot on the Jetson (opposite USB ports under heatsink).

Step 7 - Power on the tracker

Ensure all your hardware in connected like in the diagram at the top of the page i.e.

  • Ethernet cables

    • Router -> Ethernet switch

    • Ethernet switch -> Jetson

    • Ethernet switch -> camera

  • Barrel jacks connectors

    • Jetson device

    • Ethernet switch

    • Camera

  • Connect the Jetson to a monitor / tv using HDMI or DP port. Also connect a USB keyboard and mouse to the ports on the Jetson (one time only)

  • Finally, switch on the PSU toggle switch to power everything on for the first time!
