    The LPM can be controlled via commands on its serial (RS485) interface, using the Modbus RTU protocol. It is possible to control every aspect and setting of the LPM, as is done by the Stauff LASPAC- View control software. All results and counts are available in all supported formats. We suggest using LASPAC-View to initially configure the LPM and check it is performing correctly, and then the customer- written software only has to read the test results.
