NetLinx Control Cards and NetModules

NetLinx Control Cards can be installed in either the NXF CardFrame, 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 input

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

1-65,000 Generates the IR or serial command assigned to that channel.

1-199 Provides intelligent feedback; if a channel with an 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

Disables the 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

Enables carrier signals

(default setting).

Syntax:

SEND_COMMAND <DEV>,'CARON'

Example:

SEND_COMMAND IR_1,'CARON'

Starts transmitting IR carrier signals to the IR_1 port.

Sends IR pulses to select a

channel. All channels

below 100 are transmitted

as two digits. If the IR code

for ENTER (#21) is loaded,

an Enter will follow the

number. If the channel is

greater than or equal to

100, the IR function 127 is

generated for the one

hundred digit.

Syntax:

SEND_COMMAND <DEV>,"'CH',<Channel>"

Channel: 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

(duration) is set with the CTON command.

• Waits until the time (set with the CTOF command) elapses.

• Transmits IR signals for channel 8 (IR code 18).

• Waits for the time (set with the CTOF command) to elapse. If the

IR code for Enter (IR code 21) exists in the program, the NXC-

IRS4 performs step 5.

• Transmits IR signals for Enter (IR code 21).

Clears buffered IR com-

mands, and sends a single

IR pulse. You can set the

Pulse and Wait times with

the CTON and CTOF

commands.

Syntax:

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

Number: 1-252 and 256-65,000 (253-255 are reserved)

Example:

SEND_COMMAND IR_1,"'CP',2"

Clears the active/buffered commands and pulses IR_1 port's

channel 2.

CTOF

Sets the duration of off time

(no signal) between IR

pulses for channel and IR

function transmissions. Off

time settings are stored in

non-volatile memory. The

factory default for channel

off time is 5 (.5 second).

This command is

associated with the SP

(single pulse) and CP

(clear pulse) commands.

The CTON command sets the pulse length for each digit and CTOF

command sets the time between digits or any other pulse.

Syntax:

SEND_COMMAND <DEV>,"'CTOF',<Time>"

Time: 0-255 in tenths of a second increments

Example:

SEND_COMMAND IR_1,"'CTOF',10"

Sets the off time between each IR pulse to 1 second.

CTON

Sets the total time of IR

pulses transmitted, and is

stored in non-volatile

memory. The factory

default time setting for

pulses is 5 (.5 second).

Syntax:

SEND_COMMAND <DEV>," 'CTON',<Time>"

Time: 0-255 in tenths of a second increments

Example:

SEND_COMMAND IR_1,"'CTON',20"

Sets the IR pulse duration to 2 seconds.

GET MODE

Polls the IR/Serial ports

and reports the active

mode settings to the device

requesting the information.

Syntax:

SEND_COMMAND <DEV>, 'GET MODE'

Example:

SEND_COMMAND IR_1,'GET MODE'

System response example:

PORT 4 IR,CARRIER,IO LINK 0

IROFF

Halts and clears all IR out-

put 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.

POD

Disables active PON

(power on) or POF (power

off) command settings.

Channel 255 changes are enabled. This command is used in

conjunction with the I/O Link command.

Syntax:

SEND_COMMAND <DEV>,'POD'

Example:

SEND_COMMAND IR_1,'POD'

Disables PON and POF command settings on the IR_1 device.
