Rear START, STOP and RESUME terminals are use for remote batch control
using one of next methods:
A USB port (type B) is available on the M9.50 PCB. The USB connection
allows the updating of device software. To do updating it is necessary to have:
USB cable (M9.KUSB); the interface software "FLS Calibration System” and
