Class CanCBXAI420

java.lang.Object

org.lsst.ccs.subsystems.fcs.drivers.CanOpenDevice

org.lsst.ccs.subsystems.fcs.drivers.CanCBXAI420

All Implemented Interfaces:

org.lsst.ccs.framework.HasLifecycle, ADCInterface, AlertRaiser, PieceOfHardware, EmergencyMessageListener

public class CanCBXAI420
extends CanOpenDevice
implements ADCInterface

This class represents the electronic device used in autochanger to plug the proximity sensor. The proximity sensor is used to know at which distance are the autochanger trucks from the focal plan. The value returned by the sensor is the quantity readAnalogInput for the input where the sensor is plugged (01). It has to be multiplied by NANO_VOLTS_PER_BIT to obtain a voltage value in nano volts.
