Advanced Navigation Boreas D90 - Pressure Depth Transducer (Deprecated); Left Wheel Speed Sensor; Right Wheel Speed Sensor; Wheel Speed Sensor

10.6.1.20 Pressure Depth Transducer (deprecated)
Type:
Frequency Input
GPIO Port:
1, 2
Auxiliary:
Receive
Description
:
This function is designed for interfacing with a legacy pressure depth transducer. These
are no longer available and the function is now deprecated.
10.6.1.21 Left Wheel Speed Sensor
Type:
Frequency Input
GPIO Port:
1, 2
Auxiliary:
Receive
Description:
This function is designed for the left wheel of a vehicle with dual wheel speed sensors.
10.6.1.22 Right Wheel Speed Sensor
Type:
Frequency Input
GPIO Port:
1, 2
Auxiliary:
Receive
Description:
This function is designed for the right wheel of a vehicle with dual wheel speed sensors.
10.6.1.23 Wheel Speed Sensor
Type:
Frequency Input
GPIO Port:
1, 2
Auxiliary:
Receive
Description
:
This function is designed for high resolution vehicle speed sensors and wheel speed
sensors. It expects a normally low input with a high state for the trigger. If the pulse length
is more than 0.1 metres the odometer input function should be used, if it is less than 0.1
metres the wheel speed sensor function should be used. Contact Advanced
Navigation support@advancednavigation.com for help integrating with your speed
sensor.
