The RS-485 bus protocol allows for multiple devices to communicate on a Bidirectional Bus with a master RS232 Controller such as a PC COM port.
While it is possible to use any commercially available RS485 converter with the EZStepper & EZServo products, this converter has been customized to combine the power wires with the serial data from a standard DB9 serial connector and send it to a 4 pin connector that has the same pinout as the EZStepper / EZServo 4 wire bus.
This converter operates from 12V to 40V. Please consult the factory if you need to run at a lower voltage.
