# Getting Started

A quick start guide to help you setup your Syrus 4G IoT Telematics Gateway.

Syrus 4

# What you get

  • Syrus 4G IoT device
  • 1 internal battery
  • 5-in-1 combo antenna (WiFi x2, GPS/GNSS, LTE/Cellular x2)
  • 3 wiring harnesses (4 pin - Power, 14 pin - Interfaces, 16 pin - Inputs/Outputs)

# What you'll need

  • Power supply (12-36V DC)


  • Micro USB cable
  • Ethernet cable (CAT 5/5e/6)
  • microSD card (up to 512GB)
  • SIM Card (standard size)

# Connection

5in1 Combo antenna connection

5in1 Antenna Connection

Pinout connections

Note that for dual colored cables, the first color is the primary which accounts for 90% of the cable's color, the secondary color is a thin line of the cable.

# Setup

If you have a Micro USB cable (opens new window) you can follow these steps:

  1. Make sure the Syrus is powered down.
  2. Connect the 5-in-1 combo antenna to the device antenna connectors.
  3. Plug in the USB cable to the computer and connect the micro connector to the Syrus.
  4. Connect the 4 pin power molex to the Syrus and connect the RED and BLACK power cables to the 12 volt power supply. Wait 60 seconds.
  5. From the same molex connect the YELLOW (Ignition) cable to 12V in order for the device to remain ON and not go into power saving mode.

Depending on the operating system your computer could automatically recognize a new USB device and install the necessary drivers.
Give it another minute while it detects and installs it, if successful you can move on to the User Interface section or shell access.

Otherwise keep reading for intructions on installing the drivers manually.

# Windows

If 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 (opens new window) / Alternate driver (opens new window).

# User Interface

The Syrus 4 UI, also known as the management tool interface, is the graphical UI that allows you to interact and program the device.

With the micro USB cable connected to the computer open a web browser and visit the page: (opens new window)

You should see the following screen on login

The default login info is:

Username: syrus4g
Password: 123456

# Hotspot/Router discovery

Syrus 4 comes preprogrammed to find an access point with the following credentials over the 2.4GHz band:

SSID: Syrus4G
Pass: syrus1234

this means that once it's powered up if you have a router broadcasting that SSID and password, Syrus can connect to it and you can find it on your network. Check the troubleshooting page for instructions.

# Getting Online

# Wireless

The Wireless tab on the user interface gives you access to wireless access points on the 2.4 GHz network. Select the network and enter the passphrase to connect.

Once the device has an IP address assigned you can unplug the USB cable and visit that IP address to access it:

Alternatively you can visit the hostname syrus-IMEI.local on a web browser to access it, example: http://syrus-867698040012345.local

# Cellular/Mobile

Syrus comes with an embedded SIM card that requires activation. To activate it you must first put it in a MB monthly plan and then change the status to "Active" in your Pegasus Gateway instance. Once it's in a plan and activated you can instruct Syrus 4G to use that SIM card via the Mobile menu.

You can also choose to select an external SIM and enter its APN settings below.

# Shell access

For secure shell (SSH) access you can use the following ssh command on terminal or a similar program like PuTTY (opens new window)

ssh syrus4g@

You can also get the IP address from your router's device list or from a network scanning smartphone application (make sure your phone and the Syrus are on the same network).

# Programming

In order to program the Syrus to report to any endpoint you'll need to go into the Application Manager section from the menu and there you'll find the SyrusJS app. Click the Check for updates button to make sure you're running the latest version.

After downloading the latest version you'll want to expand the menu and create an instance of the application.


Open the instance and navigate to the DATA FOLDER tab, then upload any of the configurations from our repo (opens new window).

Go back to the INFORMATION tab and click Start.

You can view the logs from the LOGS menu.

# 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 via an apx tool or the Syrus 4 UI.

# Remote management

Syrus 4 communicates with a remote management software called Syrus Cloud, that's used for administering and configuring your Syrus 4 devices remotely. For more information visit Syrus Cloud.
