NetLinx Programming of DXLink Transmitters and Receivers

Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver

IR SEND_COMMANDs

On the DXLink Transmitters and Receiver Modules, IR CHANNELS and SEND_COMMANDs are sent to Port 3

(IR output).

IR CHANNELs

IR SEND_COMMANDs

Channel Function

1-255 Generate the IR or serial command assigned to that channel.

IR SEND_COMMANDs (Transmitters and Receivers)

Command Description

CAROFF

Disable the IR carrier

signal until a 'CARON'

Send Command is

received.

Syntax:

SEND_COMMAND <DEV>,"'CAROFF'"

Example:

SEND_COMMAND IR_1,"'CAROFF'"

Stops transmitting IR carrier signals to the IR port.

CARON

Enable the IR carrier

signals (default).

Syntax:

SEND_COMMAND <DEV>,"'CARON'"

Example:

SEND_COMMAND IR_1,"'CARON'"

Starts transmitting IR carrier signals to the IR port.

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.

Note: Set the Pulse and Wait times with 'CTON' and 'CTOF' (see the next page).

Syntax:

SEND_COMMAND <DEV>,"'CH',<channel number>"

Variable:

channel number = 0 to 199 channels

Example:

SEND_COMMAND IR_1,"'CH',18"

The IR port on the DXLink TX or RX 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 to elapse.

If the IR code for Enter (IR code 21) is programmed, the module performs the following

steps:

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

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

Halt and clear all active or

buffered IR commands,

and then send a single IR

pulse.

Pulse and Wait times can be set with the 'CTON' and 'CTOF' commands.

Syntax:

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

Variable:

code = IR port’s channel value 0 to 252 (253 to 255 reserved).

Example:

SEND_COMMAND IR_1,"'CP',2"

Clears the active/buffered commands and pulses IR port’s channel 2.
