Programming Information
NXC-IRS4 SEND_COMMANDS
CAROFF
Disable the IR carrier
signal until a 'CARON'
command is received.
CARON
Enable the IR carrier
signals (default).
CH
Send IR pulses for the
selected a channel.
CP
Halt and Clear all active
or buffered IR commands, and then send a
single IR pulse. Set the
Pulse and Wait times
with the 'CTON' and
'CTOF' commands.
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.
CTON
Set the total time of IR
pulses transmitted and is
stored in non-volatile
memory.
GET MODE
Poll the IR/Serial port's
configuration parameters and report the active
mode settings to the
device requesting the
information.
IROFF
Halt and Clear all active
or buffered IR commands
being output on the
designated port.
Syntax:
SEND_COMMAND <DEV>,"'CAROFF'"
Example:
SEND_COMMAND IR_1,"'CAROFF'"
Stops transmitting IR carrier signals to the IR_1 port.
Syntax:
SEND_COMMAND <DEV>,"'CARON'"
Example:
SEND_COMMAND IR_1,"'CARON'"
Starts transmitting IR carrier signals to the IR_1 port.
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.
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.
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.
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.
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
Syntax:
SEND_COMMAND <DEV>,"'IROFF'"
Example:
SEND_COMMAND IR_1,"'IROFF"
Immediately halts and clears all IR output signals on the IR_1
port.
NXC-IRS4 SEND_COMMANDS (Cont.)
POD
Disable previously active
'PON' (power on) or
'POF' (power off) command settings.
This command is used in
conjunction with the I/O
Link command.
POF
Turn OFF a device
connected to an IR port
based on the status of
the corresponding I/O
Link input.
PON
Turn ON a device
connected to an IR port
based on the status of
the corresponding I/O
Link input.
PTOF
Set the time duration
between power pulses in
.10-second increments.
Time is given in 1/10ths
of a second.
This time increment is
stored in permanent
memory.
PTON
Set the time duration
between power pulses in
.10-second increments.
Time is given in 1/10ths
of a second.
This time increment is
stored in permanent
memory.
SET INPUT LINK
Sets an IR device to link
to an input channel for
use with 'PON' and 'POF'
commands.
The input channel is
used for power sensing
(via a PCS).
Channel 255 changes are enabled.
Syntax:
SEND_COMMAND <DEV>,"'POD'"
Example:
SEND_COMMAND IR_1,"'POD"
Disables the 'PON' and 'POF' command settings on the IR_1
device.
If at any time the IR sensor input reads that the device is ON
(such as if someone turned it on manually at the front panel),
IR function 28 (if available) or IR function 9 is automatically
generated in an attempt to turn the device back OFF. If three
attempts fail, the IR port will continue executing commands in
the buffer. If there are no commands in the buffer, the IR port
will continue executing commands in the buffer and trying to
turn the device OFF until a 'PON' or 'POD' command is
received.
If the IR port fails to turn the device OFF, a PUSH and
RELEASE is made on channel 254 to indicate a power failure
error. You can only use the 'PON' and 'POF' commands when
an IR device has a linked I/O channel. Channel 255 changes
are disabled after receipt of this command. You can only use
the PON and POF commands when an IR device has a linked
I/O channel.
Syntax:
SEND_COMMAND <DEV>,"'POF'"
Example:
SEND_COMMAND IR_1,"'POF'"
Sends power down IR commands 28 (if present) or 9 to the
IR_1 device.
If at any time the IR sensor input reads that the device is OFF
(such as if one turned it off manually at the front panel), IR
function 27 (if available) or IR function 9 is automatically generated in an attempt to turn the device back ON. If three attempts
fail, the IR port will continue executing commands in the buffer
and trying to turn the device On.
If there are no commands in the buffer, the IR port will continue
trying to turn the device ON until a 'POF' or 'POD' command is
received. If the IR port fails to turn the device ON, a PUSH and
RELEASE is made on channel 254 to indicate a power failure
error.
You can only use the 'PON' and 'POF' commands when an IR
device has a linked I/O channel. Channel 255 changes are
disabled after receipt of this command.
Syntax:
SEND_COMMAND <DEV>,"'PON'"
Example:
SEND_COMMAND IR_1,"'PON'"
Sends power up IR commands 27 or 9 to the IR_1 port.
This command also sets the delay between pulses generated
by the 'PON' or 'POF' send commands in tenths of seconds. It
also sets the delay required after a power ON command before
a new IR function can be generated. This gives the device time
to power up and get ready for future IR commands. It also sets
the delay required after a power ON command before a new IR
function can be generated. This gives the device time to power
up and get ready for future IR commands.
Syntax:
SEND_COMMAND <DEV>,"'PTOF',<time>"
Time = 0 - 255. Default is 15 (1.5 seconds).
Example:
SEND_COMMAND IR_1,"'PTOF',15"
Sets the time between power pulses to 1.5 seconds for the
IR_1 device.
This command also sets the pulse length for each pulse generated by the 'PON' or 'POF' send commands in tenths of seconds.
Syntax:
SEND_COMMAND <DEV>,"'PTON',<time>"
Time = 0 - 255. Default is 5 (0.5 seconds).
Example:
SEND_COMMAND IR_1,"'PTON',15"
Sets the duration of the power pulse to 1.5 seconds for the
IR_1 device.
Syntax:
SEND_COMMAND <DEV>,"'SET INPUT LINK
<channel>'"
Channel = 1 - 4. Setting the channel to 0 disables the link.
Examples:
SEND_COMMAND IR_1,"'SET INPUT LINK 0'"
SEND_COMMAND IR_1,"'SET INPUT LINK 1'"
Sets the IR_1 port link to I/O channel 1.
SET IO LINK
Link an IR or Serial port
to a selected I/O channel
for use with the 'DE',
'POD', 'PON', and 'POF'
commands.
SET MODE
Set the IR/Serial ports for
IR or Serial-controlled
devices connected to a
CardFrame or NetModule.
Sets an IR port to either
IR or Serial mode.
SP
Generate a single IR
pulse.
XCH
Transmit the selected
channel IR codes in the
format/pattern set by the
'XCHM' send command.
XCHM
Changes the IR output
pattern for the 'XCH'
send
command.
Syntax:
SEND_COMMAND <DEV>,"'SET IO LINK <I/O
number>'"
I/O number = 1 - 4. An I/O channel to 0 disables the I/O link.
Example:
SEND_COMMAND IR_1,"'SET INPUT LINK 1'"
Sets the IR_1 port link to I/O channel 1. The IR port uses the
specified input as power status for processing PON and POF
commands.
Note: This command is included for older programs only. The
Input port is not an I/O. No output functions are available.'SET
IO LINK' applies the same configuration as the 'SET INPUT
LINK' command.
Syntax:
SEND_COMMAND <DEV>, 'SET MODE <mode>'"
Mode = IR or Serial.
Examples:
SEND_COMMAND IR_1,"'SET MODE IR'"
Sets the IR_1 port to IR mode for IR control.
You can use the 'CTON' to set pulse lengths and the 'CTOF' for
time off between pulses.
