Function description and mode setting
Receiving module
When the module is powered on and started, the red and blue LEDs will light up
for configuration, and go off to represent the completion of configuration,
after which if the red LED blinks twice to represent the receiving mode, the
blue LED blinks twice to represent the transmitting mode.
Momentary mode: press the learning button of the receiving module once,
and the red indicator will be on after flashing once. Press the key of the
transmitting module to be matched, and the red indicator of the receiving
module will flash 5 times, indicating that the matching is successful. After
that, press and hold the button of the matched transmitting module, the output
pin of the receiving module outputs high level, release the button, the
corresponding pin output of the receiving module becomes low level, and each
time the receiving module receives a signal, the transmitting module will
receive a feedback signal, and the blue indicator will flash for 3 times and
then go out. Toggle mode: press the learning button of the receiving module
twice, and the red indicator will flash for 2 times and then be on normally.
Press the key of the transmitting module to be matched, and the red indicator
of the receiving module will flash for 5 times, indicating that the matching
is successful. After that, press the key of the matched transmission mode, the
output pin on the receiving module outputs high level and remains unchanged.
Press the same key again, the corresponding pin output of the module becomes
low level. Each time the receiving module receives a signal, the transmitting
module will receive a feedback signal, and the blue indicator will flash for 3
times and then go out. Latched mode: press the learning button of the
receiving module for 3 times, and the red indicator will be on after flashing
for 3 times. Press the button of the transmitting module to be matched, and
the red indicator of the receiving module will flash for 5 times, indicating
that the matching is successful. Then, press the key of the matched
transmission mode, and the corresponding output pins on the receiving module
output high level, which remains unchanged, and other pins output low level.
If two keys are pressed at the same time, all output pins on the receiving
module output low level, which remains unchanged. Each time the receiving
module receives a signal, the transmitting module will receive a feedback
signal, and the blue indicator will flash three times and then go out.
Clear code reset function: after pressing the learning button of the
receiving module for 8 times, the red indicator light on the receiving module
flashes for 8 times and then goes out, all output pin outputs become low
level, and all stored transmission module addresses on the receiving module
are cleared.
Mode conversion function: after pressing the learning button of the
receiving module for 5 times, the red indicator on the receiving module
flashes 8 times, the module switches from the receiving mode to the
transmitting mode, and the red indicator on the receiving module flashes
twice, indicating that the conversion is successful.
Transmitting module
Mode conversion function: after pressing the learning button of the receiving
module for 5 times, the red indicator on the receiving module flashes 8 times,
the module switches from the receiving mode to the transmitting mode, and the
red indicator on the receiving module flashes twice, indicating that the
conversion is successful.
Transmitter Module
When the module is powered on and started, the red and blue LEDs will light up
for configuration, and go off to represent the completion of configuration,
after which if the red LED blinks twice to represent the receiving mode, the
blue LED blinks twice to represent the transmitting mode.
Package size
Matters needing attention:
RF devices are voltage-sensitive devices. If the power supply is unstable or the ripple is large, please add a filter at the power input to ensure that the power supply voltage does not exceed the maximum working voltage of the product. This device is an electrostatic-sensitive device, and anti-static measures must be taken during transportation and use.
Make sure that the temperature does not exceed 245 ℃ when mounting. It is recommended not to use spring antenna with rubber in application to ensure better yield of products.
