LCX-K107 digital I/O ports and binning function. A further option for the LCX100/LCX200 instruments is a set of digital I/O ports. This includes a trigger input (implemented as a BNC connector) and eight data lines for binning. With this function, the measurement results can be divided into up to eight tolerance ranges and the measured components sorted by their values (controlled via these digital lines) into sorting containers installed by the customer. The hardware of the LCX-K107 option is already installed; the function is activated using a keycode.
