Powering up

  1. Connect the RED and BLACK power cables to the 12 volt power supply (preferably to the DC connectors if you have one). Wait a few seconds while the device boots up. The boot up process takes about ~30 seconds.
  1. Connect the YELLOW (Ignition) cable to 12V in order for the device to remain ON and not go into an automatic power saving mode.

Your device is now powered up, proceed to either the desktop or mobile instructions below.

Accessing the device

Desktop instructions

Grab a micro USB cable and plug in the USB side to the computer and connect the micro connector side to the Syrus.

Depending on the operating system your computer could automatically recognize a new USB device and install the necessary drivers.

In the event your Windows computer does not recognize the Syrus, you'll need to download the one of the following drivers and install it manually.
Main driver / Alternate driver.

Syrus uses a programming language called Syruslang to quickly interface with its peripherals and start sending data to any endpoint, you can do things like once ignition is detected start a video stream and report a location message periodically every minute, it's highly customizable and you can learn more about it in our Syruslang guide.

To develop and work on your configuration locally we recommend you use the management tool's Application Manager to install and edit configurations quickly.

Once your configuration is ready you can upload it to your device remotely using Syrus Cloud's application page. This way you can make modifications over the air and synchronize it across your entire fleet of devices.


The installation of the device requires that you connect it to a power supply of 12-36V, follow the connect guide's General Installation page for more information.

Once your device is securely installed inside a vehicle you must calibrate it using the self alignment procedure, follow the connect guide Accelerometer Detection for more information.

Things to keep in mind

Automatic Sleep Mode
Once the Syrus is powered if the Ignition wire is not connected to power, the device will go to sleep automatically after 5 min. While the device is asleep the red LED will flash 1 time every 5 seconds.
To prevent the device from entering sleep mode simply power the yellow ignition wire from the 4 pin wiring harness.
You can change the sleep mode configuration remotely via the Power Save Mode (PSM) profile.
