Communications (USB)
The load cell to USB adaptor will communicate as a simple serial device rather than a ‘native’ USB device. Once the device is plugged into a PC and the supplied drivers are installed, the device will appear as a Virtual Serial Port to the PC. Standard Modbus drivers, configurations and libraries can be used with this device. Mantracourt will also supply a driver for its own ‘Instrument Explorer’ software. Because each device, when plugged into a PC, creates an additional serial port, the total number of devices that can be attached to the PC may be limited by the communication software’s ability to utilise these multiple ports i.e. an existing Modbus communication program may only support COM1 to COM4.
