NI-3101-SIG Signature Series NetLinx Integrated Controller
IR/Serial Send_Commands (Cont.)
Command Description
CH
Send IR pulses for the
selected 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',<channel number>"
Variable:
channel number = 0 - 199.
Example:
SEND_COMMAND IR_1,"'CH',18"
This device 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 Controller performs
steps 5 and 6.
• 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 commands, and
then send a single IR pulse.
You can set the Pulse and Wait times with the 'CTON' and 'CTOF' commands.
Syntax:
SEND_COMMAND <DEV>,"'CP',<code>"
Variable:
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>"
Variable:
time = 0 - 255. Given in 1/10ths of a second. Default is 5 (0.5 seconds).
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>"
Variable:
time = 0 - 255. Given in 1/10ths of a second. Default is 5 (0.5 seconds).
Example:
SEND_COMMAND IR_1,"'CTON',20"
Sets the IR pulse duration to 2 seconds.
