NXC-IRS4 Send_Commands (Cont.)

Command	Description

CH	Send IR pulses for the selected a channel. All channels below 100 are transmitted as two digits. If the
	IR code for ENTER (function #21) is loaded, an Enter will follow the number. If the channel is greater
	than or equal to (>=) 100, then IR function 127 or 20 (whichever exists) is generated for the one
	hundred digit. Uses 'CTON' and 'CTOF' times for pulse times.
	Syntax:
	SEND_COMMAND <DEV>,"'CH',<Number>"
	Variable:
	channel number = 0 - 199.
	Example:
	SEND_COMMAND IR_1,"'CH',18"
	The NXC-IRS4 performs the following:
	• Transmits IR signals for 1 (IR code 11). The transmit time is set with the CTON command.
	• Waits until the time set with the CTOF command elapses.
	• Transmits IR signals for 8 (IR code 18).
	• Waits for the time set with the CTOF command elapses. If the IR code for Enter (IR code 21) is
	programmed, the IRS4 performs the following steps.
	• Transmits IR signals for Enter (IR code 21).
	Waits for the time set with the CTOF command elapses.

CP	Halt and Clear all active or buffered IR commands, and then send a single IR pulse. You can set the
	Pulse and Wait times with the 'CTON' and 'CTOF' commands.
	Syntax:
	SEND_COMMAND <DEV>,"'CP',<code>"
	Variable:
	code = IR port's channel value 0 - 252 (253 - 255 reserved).
	Example:
	SEND_COMMAND IR_1,"'CP',2"
	Clears the active/buffered commands and pulses IR_1 port's channel 2.

CTOF	Set the duration of the Off time (no signal) between IR pulses for channel and IR function
	transmissions. Off time settings are stored in non-volatile memory. This command sets the delay time
	between pulses generated by the 'CH' or 'XCH' send commands in tenths of seconds.
	Syntax:
	SEND_COMMAND <DEV>,"'CTOF',<time>"
	Variable:
	time = 0 - 255. Given in 1/10ths of a second. Default is 5 (0.5 seconds).
	Example:
	SEND_COMMAND IR_1,"'CTOF',10"
	Sets the Off time between each IR pulse to 1 second.

CTON	Set the total time of IR pulses transmitted and is stored in non-volatile memory. This command sets
	the pulse length for each pulse generated by the 'CH' or 'XCH' send commands in tenths of seconds.
	Syntax:
	SEND_COMMAND <DEV>,"'CTON',<time>"
	Variable:
	time = 0 - 255. Given in 1/10ths of a second. Default is 5 (0.5 seconds).
	Example:
	SEND_COMMAND IR_1,"'CTON',20"
	Sets the IR pulse duration to 2 seconds.
