#1: A correct CAN network topology is important to avoid CAN communication errors caused by signal reflection or disturbance. The user must ensure proper termination on the CAN bus. The XVN cable must be at most 30 cm to the CAN bus line. If you require a longer cable, you must provide a setup that ensures the integrity of the communication.
#2: When using the I/O connector, the PWR_SHDN pin should be driven low. To shut down the sensor, drive this pin high (3-12 V). The sensor will only restart when the pin is driven low again. This behavior applies to all sensors with version number 1.2A/B or later (refer to the label on the sensor). For sensors with version numbers 1.0 and 1.1, the pin must be driven high during operation (3.3 V) and can be driven low to reset the sensor.
#3: When using the I/O connector, the pin 6 should be driven low.

GNSS connectors

The Vision Navigator contains two GNSS receivers that can connect to an antenna via the female SMA connectors labeled GNSS 1 and GNSS 2.

 

 

WiFi connector

The Vision Navigator can significantly increase its Wi-Fi range by connecting a Wi-Fi antenna to the female RP-SMA connector labeled Wi-Fi.

 

 

USB-C connector

The Vision Navigator contains a USB-C port to connect an external drive for data recording. With firmware version 2.63 and later, the user can also use this port to access the recovery mode (see Sensor configuration).Note that the USB-C port must only be used as a service interface, not during operation.
