| − | + | {{damage|SimpleMotion V2 devices use pins 3, 6 and 8 (RS485_A,RS485_B and GND) for serial communication. If something interferes these lines, communication may fail or devices may be damaged. Before powering 24V to any of the pins, ensure that pins 3 and 6 are not connected to any external circuit. It's also highly recommended to use current limited 24V power source for initial tests to reduce risk of damage (0.15-0.3A limit).}} | |
