CH SEND_COMMAND
Instruction Manual – DXLink Fiber Transmitters and Receivers
IR SEND_COMMANDs (Transmitters and Receivers), continued
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.
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.
CTON
Set the total time of IR pulses
transmitted and is stored in
non-volatile memory.
• 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' (see page 88) and 'CTOF'
(see page 88).
Syntax:
SEND_COMMAND <DEV>,"'CH',<channel number>"
Valid responses:
channel number = 0 to 199 channels
Example:
SEND_COMMAND IR_1,"'CH',18"
The IR port on the DXLink Fiber 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 elapses.
If the IR code for Enter (IR code 21) is programmed, the unit performs the
following steps:
• Transmits IR signals for Enter (IR code 21).
• Waits for the time set with the CTOF command elapses.
Pulse and Wait times can be set with the 'CTON' and 'CTOF' commands.
Syntax:
SEND_COMMAND <DEV>,"'CP',<code>"
Valid responses:
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.
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>"
Valid responses:
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.
This command sets the pulse length for each pulse generated by the 'CH' (see
page 88) or 'XCH' (see page 89) Send Commands in tenth of a second
increments.
Syntax:
SEND_COMMAND <DEV>,"'CTON',<time>"
Valid responses:
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.
