Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
IR SEND_COMMANDs (Transmitters and Receivers), continued
Command Description
CP
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.
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 to 255. Given in 1/10th of a second increments. 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' (see
previous page) or 'XCH' (see next page) Send Commands in tenth of a second
increments.
Syntax:
SEND_COMMAND <DEV>,"'CTON',<time>"
Variable:
time = 0 to 255. Given in 1/10th of a second increments. Default is 5
(0.5 seconds).
Example:
SEND_COMMAND IR_1,"'CTON',20"
Sets the IR pulse duration to 2 seconds.
GET MODE
Poll the IR/Serial port’s
configuration parameters
and report the active mode
settings to the device
requesting the
information.
Note: Works with Port 3
only.
Syntax:
GET MODE
The port responds with:
<port #> <mode>,<carrier>,<io link channel>.
Example:
SEND_COMMAND IR_1,"'GET MODE'"
The system could respond with:
PORT 3 IR,CARRIER,IO LINK 0
IROFF
Halt and clear all active or
buffered IR commands
being output on the
designated port.
Syntax:
SEND_COMMAND <DEV>,"'IROFF'"
Example:
SEND_COMMAND IR_1,"'IROFF'"
Immediately halts and clears all IR output signals on the IR port.
