		1	Commands are sent as comma delimited ASCII text. White space characters are removed but should be avoided. Multiple commands can be sent in a single transaction, and each command must be separated by <CR><LF> (0x0D & 0x0A HEX) characters.
		2
		3	The format for commands sent to a cRIO is as follows:
		4	Base_command,Parameter_1,Parameter_2,Parameter_3,Parameter_N
		5
		6	Base commands are:
		7	\|OPEN\|Sets a channel to TRUE
		8	\|ON\|Sets a channel to TRUE
		9	\|TRUE\|Sets a channel to TRUE
		10	\|CLOSE\|Sets a channel to FALSE
		11	\|OFF\|Sets a channel to FALSE
		12	\|FALSE\|Sets a channel to FALSE
		13	\|CLOSE-ALL\|Sets all channels on all modules to FALSE
		14	\|SHUTDOWN\|Sets all channels on all modules to FALSE
		15	\|FLUSH-QUEUE\|Clears the scheduled event queue
		16	\|SCHEDULE\|Creates a new scheduled event in the queue
		17
		18	__Parameters__
		19	OPEN/ON/TRUE/CLOSE/OFF/FALSE:
		20	\|Parameter 1\|Module number\|Integer representation of module number\|Valid modules for an NI-9074 are 1, 2, 3, 4, 5, 6, 7, 8\|
		21	\|Parameter 2\|Channel number\|Integer representation of channel number\|Valid channels are module dependent (0-8, 0-16, 0-32)\|
		22
		23
		24	CLOSE-ALL/SHUTDOWN:
		25	These commands have no parameters
		26
		27
		28	FLUSH-QUEUE:
		29	The flush queue command has no parameters
		30
		31
		32	SCHEDULE:
		33	\|Parameter 1\|Date-Time stamp\|The date and time for the task to be executed\|Format must be "YYYY/MM/DD@hh:mm:ss" in 24-hour format\|
		34	\|Parameter 2\|Task command\|The command to execute at the specified date + time\|Valid commands are OPEN,ON,TRUE,CLOSE,OFF,FALSE,CLOSE-ALL,SHUTDOWN\|
		35	\|Parameter 3\|Module number\|Integer representation of module number\|Valid modules for an NI-9074 are 1, 2, 3, 4, 5, 6, 7, 8\|
		36	\|Parameter 4\|Channel number\|Integer representation of channel number\|Valid channels for an NI-9074 are 0-32\|
		37
		38	Some example commands are shown below:
		39
		40	{{box}}
		41	FLUSH-QUEUE
		42	OPEN,1,0
		43	CLOSE,3,16
		44	SCHEDULE,2014/10/31@22:00:00,OPEN,3,16
		45	SCHEDULE,2014/10/31@23:00:00,CLOSE,3,16
		46	{{/box}}
		47
		48	These commands will:
		49	Clear the command queue
		50	Open (set to true) channel 0 on module 1 immediately
		51	Close (set to false) channel 16 on module 3 immediately
		52	Create a scheduled event for Oct. 31, 2014 at 10:00 PM to open (set to true) channel 16 on module 3
		53	Create a scheduled event for Oct. 31, 2014 at 11:00 PM to close (set to false) channel 16 on module 3
