Pin out table

Note

The pin numbering may not be the same as the one used by the connector manufacturer. Please refer to SBG provided pin numbering (in drawings)

Note

All Synchronization inputs and outputs, as well as odometer input pins have inverted polarity when compared to the firmware documentation, web page configuration and API web interface.

The “Rising edge” configuration in the web page, firmware and API web interface will be in fact triggered on the falling edge at hardware level. This is because these inputs and outputs have been optimized for direct interfacing to a RS-232 receiver or driver, which can enable robust and safe connection to remote equipment.

An external inverting buffer can also be used to maintain LVTTL levels while putting back the signals to the same polarity as the firmware.

GNSS Antennas Connectors

 U.FL series has become a standard in the wireless industry. It provides an extremely small mounting area weight, offers high frequency performance and has a user friendly tactile lock feeling that ensures a reliable connection.

  • A1: Primary GNSS antenna,  used for positioning
  • A2: Secondary or Auxiliary GNSS antenna, used for dual antenna heading computation. When the dynamics are high enough like UAV applications, the secondary antenna is optional.

Interfaces functional specifications

Serial and TCP/UDP interfaces

Quanta Micro integrates 3x serial UART interfaces as well as 5x TCP or UDP interfaces that can be used in a similar way. These interfaces can be used for configuration, data output and interfacing with third party equipment.

The following table summarizes the capabilities of each serial interface.

Supported protocols

Quanta Micro has been designed to be connected to a large range of aiding equipment. In addition to the native sbgECom binary protocol, other third party or standard protocols are also supported such as:

  • NMEA
  • RTCM
  • TSS1
  • Septentrio SBF
  • Novatel Binary protocol
  • Trimble GNSS protocol
  • Third party ASCII outputs

For more information about protocols descriptions, please refer to the Firmware documentation.

Ethernet interface

The Ethernet interface brings various key functionalities to the Quanta Micro.

  • Web page for configuration and real time visualization purpose
  • 5x UDP / TCP/IP interfaces that can be used as additional bidirectional communication interfaces
  • FTP server for datalogger access
  • NTRIP client for easy RTK corrections input
  • PTP / NTP time servers

Odometer integration

Odometers should be connected on  ODO_A and ODO_B input signals.

Synchronization input and output

Sync In pins can be used to trigger external events and input external PPS information.

Sync Out A and B pins can be configured in the following modes :

  • Main loop divider: This event is activated at the sensor sample time, but its frequency is divided by the output divider. If the divider is set to 4, pulse output frequency will be 200Hz / 4 = 50Hz.
  • PPS: This simple output is synchronized with each top of UTC seconds. Validity should be checked by parsing the UTC messages status.
  • Virtual odometer: This output generates a pulse each X meters of travel, depending on user configuration
