Ir Send_Commands - AMX DXLink Multi-Format Wallplate Instruction Manual

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
IR SEND_COMMANDs (Transmitters and Receivers)
Command
CAROFF
Disable the IR carrier
signal until a 'CARON'
Send Command is
received.
CARON
Enable the IR carrier
signals (default).
CH
Send IR pulses for the
selected channel.
CP
Halt and clear all active or
buffered IR commands,
and then send a single IR
pulse.
Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Channel Function
1-255 Generate the IR or serial command assigned to that channel.
Description
Syntax:
SEND_COMMAND <DEV>,"'CAROFF'"
Example:
SEND_COMMAND IR_1,"'CAROFF'"
Stops transmitting IR carrier signals to the IR port.
Syntax:
SEND_COMMAND <DEV>,"'CARON'"
Example:
SEND_COMMAND IR_1,"'CARON'"
Starts transmitting IR carrier signals to the IR 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.
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.
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.
