    5 Electrical Interface 5.1 Interface Box The Interface Box that accompanies the OS2 is designed to allow the sensor to be operated for test and evaluation purposes. It terminates the interface cable from the sensor, allows it to be powered up and provides access to the sensor gigabit Ethernet Interface via a standard RJ45 connector.

  • Page 13: Direct Cable Connection And Pinout

    The OS2 can be operated without the use of an Interface Box. Warning: Ouster is not responsible for any errors in wiring as a result of bypassing the Interface Box and this activity may result in a voiding of your warranty if it results in damage to the sensor.

  • Page 14: Digital Io

    6 Digital IO 6.1 SYNC_PULSE_IN is a dedicated input channel that is accessible within the Interface Box Jumper J4. This SYNC_PULSE_IN channel expects an input pulse sequence which can be used for time synchronization. See the Soft- ware User Manual for more information on configuring this input. Any references to pulse polarity in this document references the signal polarity on the pin of the sensor.

    6.2 MULTIPURPOSE_IO (M_IO) ) is a configurable input or output channel accessible within the Interface Box MULTIPURPOSE_IO M_IO Jumper J4 connected to the MULTIPURPOSE_IO pin of the Interface Box. Detailed information on how to configure this channel using the sensor TCP interface can be found in the API Guide. By default this channel is disabled.
  • Page 16 Table6.2: MULTIPURPOSE_IO - OUTPUT Interface Requirements Parameter Pull Up Voltage 15 V Sinking Current 25 mA When this channel is configured as an INPUT, the can accept a standard NMEA $GPRMC UART M_IO message. These messages are a common way for GPS systems to share timestamp information in UTC time format.
