3.3 With GPIO pins
There is only one GPIO pin that is an input to the module. This provides another way to shut
down the laser. This is intended as a safety feature when work is being done on the rear of
a live Flashlink rack.
When the GPIO pin is pulled to ground, the laser is disabled. See Table 1: Connector
functions in ch. 1 for GPIO pin-out.
