* ''Ch1/2 Row/Col'' − Analog current inputs to the readout system. Ch1 refers to the first channel within the plugin slot in question and is associated with the readout field on top of the screen. Ch2 is the 2nd channel displayed at the bottom. Row/Current signals accept negative currents in 100 μA steps; typically, plugins contain resistors from time slot signal lines to row/current lines. | * ''Ch1/2 Row/Col'' − Analog current inputs to the readout system.
