Programming

NXI NetLinx Integrated Controller (No Master)

IR / Serial Ports (8 - 15) Channels

IR/Serial Send_Commands

The following IR and IR/Serial Send_Commands generate control signals for external equipment.

IR / Serial Ports Channels

00001 - 00229 IR commands.

00229 - 00253 May be used for system call feedback.

00254 Power Fail. (Used with the 'PON' and 'POF' commands).

00255 Power status. (Shadows I/O Link channel status).

00256 - 65000 IR commands.

IR/Serial 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.

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.
