# ENP-CAN
# CAN Bus Module
The CAN Bus Module is used to read data from devices such as vehicles, inverters, ventilation systems, valves, irradiance sensors, power meters and others. The CAN Bus Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.

# Lua API
Lua API lets to interact with 3rd party devices via our UCMs (opens new window). It includes functions that implement various kinds of interaction. For more information please visit Enapter Developer Toolkit (opens new window) and ENP-CAN Reference (opens new window).
# Troubleshooting
# The Module Is Not Receiving Telemetry
Check the jumpers inside the ENP-CAN module (install if needed):
- Dismount the antenna from the ENP-CAN module.
- Remove the front cover.
- Remove the back side of the module.
- Carefully push the module control board down.
- Install jumper J5, jumper J3 H.speed or both according to the picture below.
