NetLinx Control Cards and NetModules

NetLinx Control Cards can be installed in either the NXF CardFrame, NI-4000, or NetModules. This document provides basic specifications and wiring information for the NetLinx Control cards. For detailed information on the cards, refer to the NetLinx CardFrame, Control Cards, and NetModules Instruction Manual.

NXC-IRS4 4-Port IR/S Control Card

The NXC-IRS4 4-Port IR/S Control Card provides four IR/Serial output control ports with LED status feedback. Each port in the NXC-IRS4 stores programmed commands for IR- or serial-controlled devices.

NXC-IRS4 Channel Assignments

The 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. If more than two device commands are sent simultaneously, only the first two devices receive the commands.

NXC-IRS4 Channel Assignments

Channel Description

1-255	Generates the IR or serial command assigned to that channel.
1-199	Provides intelligent feedback; if a channel with no IR command is turned on,
	the card will turn that channel off.
Ports 1-4 Generates 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.

	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>"
	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).
