Versatile DC load control and connectability via CAN bus are the main features of OTM system. The system includes two types of devices one gateway with USB, WiFi/BLE and CAN interface and many CAN controller devices with ability to drive up to 10A/48VDC. Beside firmware upgrade via USB interface, device allows for real time control of the controlled device via Python script. In addition to the two types of the aforementioned devices a CAN enabled 70A/48VDC motor driver boards are used.
Requirements:
- USB interface for device configuration and control
- BLE/WiFi interface for device configuration and control
- Firmware upgrade via USB interface
- CAN interface for device interconnection
- DC Actuator control via relays.
