CANrange¶
CANrange is a CAN-enabled Time-of-Flight distance measurement sensor. This product uses laser measurements to calculate precise distance to a surface parallel to the sensor. Users can also configure the CANrange to act as a limit switch or beam break sensor in the Device Configs.

Status Light Reference¶
Important
If the status lights do not exactly match any of the blink codes below, the device may be alternating between multiple blink codes (most commonly between good and bad CAN).
| Blink Codes | |||
|---|---|---|---|
| Animation (Click to play) | LED State | Cause | Possible Fix |
| LEDs Off | No Power | Provide 12V to V+ and V- inputs. | |
| Blinking Alternating Red | CANrange does not have valid CAN. | Ensure good connections between CANH and CANL (Yellow and Green) & robot controller is on. | |
| Blinking Alternating Orange | CANrange has a good CAN connection. Measured distance is not within detection threshold. | ||
| Blinking Alternating Green | CANrange has a good CAN connection. Measured distance is within detection threshold. | ||
| Alternate Red/Orange | Damaged Hardware. | Use Tuner X Self Test to confirm the LEDs and that the hardware fault is set, then contact CTRE | |
| Single LED alternates Green/Orange | CANrange in bootloader. | Field-upgrade device in Tuner X. | |
The rate at which the LED is blinking can be used as a rough indicator of measured distance. For example, the below LED shows that the detected distance is close to the CANrange.
