NetLinx Integrated Controller (No Master) - Operation Reference Guide
IR/Serial Send_Commands (Cont.)
CH 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',<Number>"
Variable:
Number = 0-199
Example:
SEND_COMMAND IR_1," 'CH',18"
The NXI 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 NXI performs steps 5 and 6.
• Transmits IR signals for Enter (IR code 21).
• Waits for the time set with the CTOF command elapses.
CP Clears buffered IR commands, 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>"
Variable:
Number = 1-252 and 256-65,000 (253-255 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.
Syntax:
SEND_COMMAND <DEV>,"'CTOF',<Time>"
Variable:
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.
Syntax:
SEND_COMMAND <DEV>," 'CTON',<Time>"
Variable:
Time = 0-255 in tenths of a second increments; default = 5 (.5 second).
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
