AXB-IRS4 IR/Serial Interface (4 Ports)
Send Commands (Cont.)
Command Description
'CH',channel number Transmit the IR pulses that select the proper channel. Enter all channel
numbers below 100 as two digits. For example, enter channel 1 as 01. If
the IR code for ENTER (#21) is loaded, an ENTER follows the number. If
the channel is greater or equal to 100, the IR Function Number (FN) 127 is
generated for the one-hundredth digit.
Variable:
channel number = 1-199
Example:
SEND_COMMAND 2, "'CH',18"
The AXB-IRS4 performs the following:
• Transmits the IR code pulses for 1 (IR code 11) for the time set by CTON.
• Waits for the time set by CTOF.
• Transmits the IR code pulses for 8 (IR code 18) for the time set by CTON.
• Waits for the time set by CTOF. If the IR code for ENTER (IR code 21) is
programmed, steps 5 and 6 are performed.
• Transmits the IR code pulses for ENTER (IR code 21) for the time set by
CTON.
• Waits for the time set by CTOF.
'CP',code Transmit IR code pulses and clear all commands in the buffer. Pulse time
is set by the CTON and CTOF commands.
Variable:
code = 1-252
Example:
SEND_COMMAND 2,"'CP',2"
Clears all pending commands in device 2, and pulses command number 2.
'CTOF',time Set the off time in tenths of a second. Default time is 5 (0.5 second). The
time is stored in non-volatile RAM.
Variable:
time = 1-255
Example:
SEND_COMMAND 2,"'CTOF',15"
Sets channel pulse's off time for device 2 to 1.5 seconds.
'CTON',time Set the on time in tenths of a second. Default time is 5 (0.5 second). Time
is stored in non-volatile RAM.
Variable:
time = 1-255
Example:
SEND_COMMAND 2,"'CTON',10"
Sets the channel pulse's on time for device 2 to 1 second.
IROFF Stop all IR code or pulses from being generated.
Example:
SEND_COMMAND 3,'IROFF'
Stops the current IR output on device 3.
