Note: The SP-20000-PMCL does not have “Opto Coupled” in and out interface.
5.3.7 GPIO
GPIO is a general interface for input and output and controls the I/O for trigger signals and
other valid signals and pulse generators. By using this interface you can control an external light
source, make a delay function for an external trigger signal, or make a precise exposure setting
together with a PWC trigger.
