00001 - 00229	IR commands.
00229 - 00253	May be used for system call feedback.
00254	Power Fail. (Used with the 'PON' and 'POF' commands).
00255	Power status. (Shadows I/O Link channel status).
00256 - 65000	IR commands.

IR/Serial Send_Commands

The following IR and IR/Serial Send_Commands generate control signals for external equipment.

IR/Serial Send_Commands

CAROFF	Syntax:
Disables the carrier signal	SEND_COMMAND <DEV>,'CAROFF'
until a CARON command is	Example:
received.
	SEND_COMMAND IR_1,'CAROFF'
	Stops transmitting IR carrier signals to the IR_1 port.
CARON	Syntax:
Enables carrier signals	SEND_COMMAND <DEV>,'CARON'
(default setting).	Example:
	SEND_COMMAND IR_1,'CARON'
	Starts transmitting IR carrier signals to the IR_1 port.
CH	Syntax:
Sends IR pulses to select a	SEND_COMMAND <DEV>," 'CH',<Number>"
channel. All channels below	Variable:
100 are transmitted as two
	Number = 0-199
digits. If the IR code for

If the channel is greater than

	• 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 NXI performs steps 5 and 6.
	• Transmits IR signals for Enter (IR code 21).
	• Waits for the time set with the CTOF command elapses.
CP	Syntax:
Clears buffered IR com-	SEND_COMMAND <DEV>,"'CP',<Number>"
mands, and sends a single IR	Variable:
pulse. You can set the Pulse	Number = 1-252 and 256-65,000 (253-255 reserved)
and Wait times with the
CTON and CTOF commands.	Example:
	SEND_COMMAND IR_1,"'CP',2"
	Clears the active/buffered commands and pulses IR_1 port's channel 2.
