SK509 is a high-power industrial-gradecode-coded remote wireless four-way switch control module from NiceRF. Itprovides four-way signal input and four-way control output interface, featuringsimple interface and reliable operation. Users can also use the user-friendlyPC software to configure and modify the relevant parameters inside the modulein a wireless manner. The DIP switch on the module can change the workingfrequency of the wireless module (16 groups optional), working mode, etc.,which makes the module very flexible and convenient to use. However, manycustomers have responded that they do not know how to use the DIP switch on theSK509 module. This article summarizes the usage method DIP switch the module onthe dial switch, hoping to help the majority of users.
DIPswitches 1-4 are the operating frequency channel selection, a total of 16groups (default factory channel interval 0.5M), the frequency value can bereconfigured by PC. The correspondence between the state of the DIP switch andthe working frequency channel set by the PC is as follows:
Note:The position of the DIP switches 1-4 between multiple modules must be the same,otherwise the communication will not be successful.
ON-is the normal communication working mode when the dial 5 switch is closed.OFF—The configuration parameter mode is when the dial 5 switch is disconnected,as shown in the figure:
（Open configuration mode）
TheDIP switch 6 is in the code mode. This mode allows the instant mode masterchannel to follow the slave channel pair code, and the channel after the codecan be controlled. When the code pair mode is performed, both modules must beDIP6 to perform the code alignment. Otherwise, the code cannot be successfullyexecuted. Figure:
(Turn on the code mode)
DIPswitch 7 is used to set the master-slave mode, the host can only set one, andthe slave can set multiple. DIP7 is closed to the main unit, and the slave isturned on. As is show below:
（Master-slave mode setting）
Remarks:Many customers find that the alarm light is always on when they are using. Mostof them are because the master-slave mode is not set, so the module can'tcommunicate, and the alarm light will be on.
（Turn on timing mode）
Ifwe modify one of the eight DIP switches, it must be re-powered before it willtake effect. Please be sure to pay attention to this.
