Description 
SK509 is an industrial four channels wireless switch control module with pairing function, it provides maximum four channel signalinput and maximum four channel control output. It features in simple interface and reliable performance. The parameters can bemodified by PC software / UART command / remote controller (SK509-S). DIP switch on the module can used to change operating frequency (maximum 16 group),operation mode etc. Using this module, user canreplace wired device with the wireless connection, which significantly reducethe cost and save much time.

Application circuit

The typical schematic circuit is as below:

 

 

 

 

Typical application: 

 The input port is pulled up internally, leave open or connect with 3.3V will result in high level, it is low level when connect to GND.

 

High level will make the output of the other side short out. And low level will make the output of the other side open. Below is regular connection:


 

Pin Definition:

 Dip switch Settings (valid when power on again )
DIP8—Normal working mode selection
ON—Real-time mode ( In this mode, when state changes in input port , it transmit signal immediately)
OFF—Timing mode (Signal transmitted at the predefined time interval according to the setting of DIP6)
DIP7—master/slave selection
ON—the master
OFF—the slave
DIP6—Time interval selection of timing mode
ON—Slow time (configurable, default 30S)
OFF—Fast time (configurable, default 2S)
DIP5—Mode selection
ON—Normal working mode
OFF—Configuration mode (Wireless setting on PC via configuration module SK509
DIP4~1 —Working frequency channel selection, total 16 channels(default channel interval: 0.5M), frequency is
configurable through PC software / UART Command/ Remote controller SK509

How to connect Antenna: The antenna is important in the communication. For this module, the match impedance is 50 Ohm. We have many kinds of antenna for customer to choose, please contact the corresponding sales engineer for help, or find the antenna in our website.

 


 

 Tips for antenna:

*Don’t close to the ground, metal, magnet, big current;

*If you are using the sucker antenna, pull the wire as straight as possible, the sucker foundation should stick with metal
