Local GPIO Option
In addition to the GPIO / PXI-Trigger lines optionally available on J2, the optional pin-header
PGPIO provides another two GPIO lines available for user specific application. The 5V level TTL
signals sio_gpio16/17 are controlled by the on-board SIO IT8761E, with an internal 50k PU
resistor and capable of sinking 24mA each.
