The plugin has not changed since it was originally written for VRUT. Here is the code for the CommandSensor function of the LabJack:
Code:
void CommandSensor(void *sensor)
{
	long idnum=-1;
	long demo=0;
	long numCh=4;
	static int tog = 1;
	long trisD = 3;
	long trisIO = 0;
	long stateD1=1;
	long stateD2 = 2;
	long state;
	long stateIO = 0;
	long updateDigital = 1;
	long outputD[3];
	long result;
	long overVoltage;
	float voltage;

	SetThreadPriority(GetCurrentThread,THREAD_PRIORITY_TIME_CRITICAL);		
	
	switch( (int) ((VRUTSensorObj *)sensor)->command) {
	case 0:						// Both eyes closed			
		state = 0;
		DigitalIO(&idnum, demo,&trisD,trisIO, &state, &stateIO, updateDigital, outputD);
		break;
	case 1:						// Left closed, right open
		state = 1;
		DigitalIO(&idnum, demo,&trisD,trisIO, &state, &stateIO, updateDigital, outputD);
		break;
	case 10:						// Left open, right closed
		state = 2;
		DigitalIO(&idnum, demo,&trisD,trisIO, &state, &stateIO, updateDigital, outputD);
		break;
	case 11:						// Both open
		state = 3;
		DigitalIO(&idnum, demo,&trisD,trisIO, &state, &stateIO, updateDigital, outputD);
		break;
	case 2:
		fprintf(stdout,"%.2f %.2f\n",((VRUTSensorObj *)sensor)->data[0],((VRUTSensorObj *)sensor)->data[1]);
		result = EAnalogOut(&idnum,demo,((VRUTSensorObj *)sensor)->data[0],((VRUTSensorObj *)sensor)->data[1]);
		fprintf(stdout,"result = %d, idnum = %d\n",result,idnum);
		break;
	case 3:
		EAnalogIn(&idnum,demo,0,0,&overVoltage,&voltage);
		fprintf(stdout,"voltage = %.2f\n",voltage);
		break;
	}
	SetThreadPriority(GetCurrentThread,THREAD_PRIORITY_NORMAL);
}
