^*1 When the measurement range is narrowed in accordance with the binning settings.
^*2 When the measurement range is set to minimum, binning is ON, and parallel imaging is ON. All other settings are default values.
^*3 When binning and parallel imaging are both ON. All other settings are default values.
^*4 Positive common connection is supported for NPN input devices, and negative common connection for PNP input devices.
^*5 Exclusively for synchronised I/O between controllers (LJ-X8000A).
^*6 The PC application (LJ-H2X) includes communication libraries (DLL) and a sample programme. Types of communication libraries (DLL): Profile output, changing various settings, laser ON/OFF control, trigger input, etc.
