KYL-815 4-way wireless ON-OFF Module
I. Introduction
This 4-way ON-OFF module is to transmit the ON-OFF condition to a remote place
wirelessly in time. When here the switch condition is ON, the output in the remote
place is ON. When the local switch condition is OFF, the other terminal is OFF.

Working method

DIP8:Working
ON—input changes trigger transmission. Once you change any of the 4-way's
condition, the module will send out this info.
OFF---fixed time transmitting. The master transmits 4-way's condition to the
slave every 1s or 2s (not real-time transmitting).

ON—slave,OFF—master
Data collecting mode choosing
DIP6
DIP6:Data
ON---Point to point transmission mode
OFF---Data collection mode
The master collects input condition or controls output condition via sending data. In
data collecting mode, the module can't send out data actively. That is to say touch off
transmitting and fix time transmitting are both invalid at this mode.
Feedback choice
DIP5

ON--feedback function close
OFF--receiver will send back the received data to transmitter
Channel choosing

DIP1-4:Channel
To avoid interference, please use different DIP switch mode and choose different
channels when you use several pairs of modules in the same place , Maximal 16
channels.

Notice:
* For most users "touch off transmitting mode" is OK-----DIP7-ON
* To avoid interference caused by more pairs of modules working in the same place,
please choose different channels for different systems.
* In timing mode, there should be a master and a slave.
* changing the DIP switch just takes effect after the module is re-powered on.

VI.. How to use KYL-815
1. Consider your specific application, set the DIP switch, connect VCC (12V-30V
DC) and connect input and output cables as per the above instruction.
2. Power supply for the module.

3. The factory setting is input changes trigger transmission mode and current
channel is No.1.
4. Choose different frequency points to avoid interference caused by more pairs of
modules working in the same area.
VII
VII.. About the LED Indicator:
1. The power LED--It is always ON if modem is power supplied.
2. The data LED--It blinks once modem transmits or receives data
3. The working LED--It blinks every 1s, this indicates modem is working normally
4. The output LED--It's on indicates the corresponding output condition is connect.
It's off indicates the corresponding output condition is disconnect.
VIII
VIII.. Working Mode Instruction
1. Touch off transmitting mode
Once there is any input change happens, the module will send it out. This mode
has the advantage of high speed, real-time transmission, and low power
consumption. Because module only transmits if there is input changes.
2. Fixed time transmitting mode
Under this mode, there should be one master and one slave module. The master
will synchronize with the slave every 1s, means the master will transmits its
condition to slave every 1S and the slave will transmits its condition to master
every 1S. If the master cannot synchronize with slave, the buzzer inside of module
will alarm. And all contacts will disconnect at the same time. This alarm will stop
automatically until the master is synchronize with slave again.
There will be at most 1s ON-OFF delay under this mode.
