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.
This is how your tracker hardware should be connected. Completed the steps in the sections below.
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.
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 -).
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.
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.
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.
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.
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.
Plug fan into Jetson board using the 4 pin connector
Next, attach the Adafruit GPS.
Connect the USB Micro-B adaptor to the Ultimate GPS and plug USB-A into a spare port on your Jetson device.
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.
Plug the USB3 storage into a spare USB port on the Jetson
Clip the NVMe drive to the Xavier e.g. as shown here https://www.youtube.com/watch?v=ZK5FYhoJqIg
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.
With a Dahua camera you can adjust the following settings for video, conditions and profile
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
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
Set day and night mode transition times in the schedule UI e.g.
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:
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).
Ensure all your hardware in connected like in the diagram at the top of the page i.e.
Router -> Ethernet switch
Ethernet switch -> Jetson
Ethernet switch -> camera
Barrel jacks connectors
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!
