This pin is used to supply the isolated interface on the ICE Platform with power. It is only necessary to supply 5V on this pin if the USB port is left unconnected. If the USB port is connected to a computer, the isolated interface will be powered from the USB cable. Even if both the USB port is connected and 5V is supplied on this pin, no damage will occur. The maximum current draw on this pin is 10mA. | This pin is used to supply the isolated interface on the ICE Platform with power.

- | The safety interlock signal prevents the Master Controller from releasing the safety interlocks on all attached daughter boards. The safety interlock is only applicable to daughter boards that have laser controllers. Without the safety interlocks released, daughter boards are prevented from powering on lasers. The safety interlock signal floats high to 3.3V and must be pulled down to ground to release the interlocks. This pin can be permanently shorted directly to ground if safety interlock functionality is not required. | + | The safety interlock signal prevents the Master Controller from releasing the safety interlocks on all attached daughter boards.
