Interfaces and Connectivity

Depending on the device type, the device provides the following interfaces:

  • Cellular communication (4G/LTE)
  • GNSS for positioning data
  • Wi-Fi/BLE
  • Ethernet (Single-Pair Ethernet via dedicated connector)
  • CAN interface via main connector

External antenna connectors may be available for cellular communication and GNSS and Wi-Fi/BLE.

Some variants include an integrated battery for temporary backup in case of power failure.
The battery is not intended as a permanent power source.

These interfaces allow connection to external devices such as PCs, smartphones, or tablets for data transmission, visualization, and analysis.

Operating Modes

The device supports the following operating modes for wireless CAN data transmission via Wi-Fi and BLE:

- CAN-BLE interface – connection to a BLE central device

Environmental Conditions

The device is designed for use in industrial environments as well as in earth-moving machinery.

Protection class IP6K7 is achieved only when all connectors are properly sealed using appropriate connectors or protection caps.
