AMX NXC-IRS4 Installation Manual

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.

Programming Information

NXC-IRS4 SEND_COMMANDS
CAROFF Syntax:
Disable the IR carrier
SEND_COMMAND <DEV>,"'CAROFF'"
signal until a 'CARON'
Example:
command is received.
SEND_COMMAND IR_1,"'CAROFF'"
Stops transmitting IR carrier signals to the IR_1 port.
CARON Syntax:
Enable the IR carrier
SEND_COMMAND <DEV>,"'CARON'"
signals (default).
Example:
SEND_COMMAND IR_1,"'CARON'"
Starts transmitting IR carrier signals to the IR_1 port.
CH All channels below 100 are transmitted as two digits. If the IR
code for ENTER (function #21) is loaded, an Enter will follow

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).
• Waits for the time set with the CTOF command elapses.

Sets the IR pulse duration to 2 seconds.
