+ | 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. | ||

+ | == EVENT == | ||
+ | The EVENT pins are used for event system signalling. EVENT_ADDR0 is the least significant bit of the 3-bit event address. EVENT_TRIGGER is used to trigger the event. The state of the EVENT_ADDR pins will be read when on the rising edge of the EVENT_TRIGGER line. Voltage signalling is at 3.3V TTL, active high. Pin definitions and usage is detailed in the [[ice: | ||
+ | === Safety Interlock BNC === | ||
+ | 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. It must be pulled to ground with less than 1kΩ of impedance. This pin can be permanently shorted directly to ground if safety interlock functionality is not required. | ||
