NXC-IRS4 Channel Assignments

The NXC-IRS4 channel settings listed in the following table set the IR output channels. The NXC-IRS4 can process up to two IR or serial device channel setting commands simultaneously.

NXC-IRS4 Channel Assignments

Channel	Description
1-255	Generate the IR or serial command assigned to that channel.
1-199	Provide intelligent feedback; if a channel with no IR command turned On, the card will turn that channel
	Off.
Ports 1-4	Generate PUSH and RELEASE statements corresponding to the state of inputs 1 - 4. A contact closure to
	GND is reported as a PUSH.
	• The PUSH and RELEASE channel is 255.
	• Channel reporting status is 255.
	• Channel 255 changes are disabled after receipt of the ’PON’ command.

Programming Information

The following NetLinx Send_Commands control the NXC-IRS4 Control Card.

NXC-IRS4 Send_Commands

Command	Description
CAROFF	Disable the IR carrier signal until a 'CARON' command is received.
	Syntax:
	SEND_COMMAND <DEV>,"'CAROFF'"
	Example:
	SEND_COMMAND IR_1,"'CAROFF'"
	Stops transmitting IR carrier signals to the IR_1 port.
CARON	Enable the IR carrier signals (default).
	Syntax:
	SEND_COMMAND <DEV>,"'CARON'"
	Example:
	SEND_COMMAND IR_1,"'CARON'"
	Starts transmitting IR carrier signals to the IR_1 port.
