There are two connectors for power but you only need to provide 24VDC power to one of them. **Important** : Connect the SG (signal ground) terminal to the ground of the main unit (CUWIN, CPCV5, etc.) in addition to the + and - terminals of the 485 communication port. {{ :modport:md-h485:mdh485.png?nolink |}} * RS-485 Port (57,600 baud, 8 data bits, 1 stop bit, no parity, Modbus RTU only) (Fixed – Cannot be changed) * Power LED * DC 24V power input x2 (barrel jack & 4 pin terminal) * 5V internal circuitry [[modport:index|MODPORT]]
