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.

NXC-IRS4 SEND_COMMANDS

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.

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>"

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 com-
mands, and then send a
single IR pulse. Set the
Pulse and Wait times
with the 'CTON' and
'CTOF' commands.

Syntax:

SEND_COMMAND <DEV>,"'CP',<code>"

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>"

Time = 0 - 255. Given in 1/10ths of a second. Default is 5
(0.5 sec).
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>"

Time= 0 - 255. Given in 1/10ths of a second. Default is 5
(0.5 sec).
Example:

SEND_COMMAND IR_1,"'CTON',20"

Sets the IR pulse duration to 2 seconds.

GET MODE
Poll the IR/Serial port's
configuration parame-
ters and report the active
mode settings to the
device requesting the
information.

The port responds with: <port #> <mode>,<carrier>,<io link
channel>.
Syntax:

SEND_COMMAND <DEV>,"'GET MODE'"

Example:

SEND_COMMAND IR_1,"'GET MODE"

The system could respond with:

PORT 4 IR,CARRIER,IO LINK 0

IROFF
Halt and Clear all active
or buffered IR commands
being output on the
designated port.

Syntax:

SEND_COMMAND <DEV>,"'IROFF'"

Example:

SEND_COMMAND IR_1,"'IROFF"

Immediately halts and clears all IR output signals on the IR_1
port.
