Hello alaa; Th gimac-I website staes that it communicates over Modbus RTU. Without dongle, you could try this application, provided by our friend TIB68: MODBUS RTU MASTER FOR CP340/341/441-X (NO DONGLE REQUIRED) However, the gimac-i manual provides no information on the Modbus mapping (internal registers of the unit). This is somewhat important, as you must program the functions of the CP 341 to request specific data for your communicqtions. You should ask LSIS about that information. Hope this helps, Daniel Chartier
