Frequently Asked Questions
Q: What protocol does the LIHTNE MD1202 RS485 DC motor controller use by default?
A: The MD1202 uses the PELCO-D protocol by default. If you require Modbus protocol support, this can be arranged as a custom configuration — please reach out before ordering to confirm your requirements.
Q: Can the MD1202 control two DC motors simultaneously?
A: Yes. The module features two fully independent H-bridge circuits, each capable of driving a separate DC motor at up to 2.8 A. Both channels operate independently, enabling simultaneous bidirectional control of two motors.
Q: What control methods are supported besides RS485?
A: In addition to RS485 serial communication, the MD1202 supports potentiometer control and switch control for motor direction and operation, giving you flexible integration options for a wide range of setups.
Q: What is the operating voltage range for this motor controller module?
A: The module accepts a supply voltage of DC 9V to 24V, making it compatible with most standard industrial and hobby power supplies commonly used in automation and robotics projects.
