DIP definition DIP function description: DIP8—communication mode selection ON – real-time mode ( In this mode, output sync to the input immediately once the input state changed) OFF - timing mode ( output sync to in the input at set time interval ) DIP7 - master/slave selection ON - the master OFF - the slave DIP6 – Pairing Mode Selection ON -Non-Pairing Mode OFF- Pairing Mode (In this mode, the host channel in instant mode can pair with the slave channel. Only the paired channels can be controlled) DIP5 - mode selection ON - normal working mode OFF - setting mode ( connect module to PC by SK108-S, set the parameters) DIP4 ~ 1 - working frequency channel selection, 16 channels in total (default channel interval is 0.5M), frequency can be reset by PC. Relationship between DIP switches and working frequency channel: ★Note: If any DIP switch changed, power off then power on the module again to make the set valid.

Working mode 1) Power on reset When powered on, all relays open, the LED is off, alarm LED blink once. 2) Real-time working mode In real time mode, both the master and slaver will send a inquiry signal at set time interval (default time is 3minutes) , the other side , master or slaver will reply the synchronized message. If this communication failed for continuous 3times, the alarm will light on to indicate, the related output will resume to open state； In real-time mode, if modules never paired before，it is in non paired mode. Each module has four independent input and four independent output. In real-time mode, the change of any input of the four channels will trigger the transmission, in other side the corresponding relay of the module will be synchronized after got the signal, then it returns a acknowledged signal. If no acknowledged signal come to the triggered modules, the alarm LED will light on. All the output relays will be resumed open if no acknowledge signal received for continuous 3 times inquiry. ★ Input and output status under normal working mode: The logic relationship of the module as below: Real-time mode（Bi-communication） Timing mode（One way communication） Master input Slave output Master input Slave output IN Open or pull high OUT Open IN1 Open or pull high OUT1 Open Short Close Short Close IN Open or pull high OUT Open IN2 Open or pull high OUT2 Open Short Close Short Close IN Open or pull high OUT Open IN3 Open or pull high OUT3 Open Short Close Short Close IN Open or pull high OUT Open IN4 Open or pull high OUT4 Open Short Close Short Close Slave input Master output Slave input Master output IN Open or pull high OUT Open IN1 X OUT1 Open Short Close IN Open or pull high OUT Open IN2 X OUT2Short Close IN Open or pull high OUT Open IN3 X OUT3Short Close IN Open or pull high OUT Open IN4 X OUT4Short Close

www.nicerf.com SK509 NiceRF Wireless Technology Co., Ltd. Rev 1.5 sales@nicerf.com - 7 - For example, communication between modulesA and B, the 4 output of moduleA is corresponding to the 4 input of module B, the 4 output of module B is corresponding to the 4 input of module A, shown as below: In real time mode,SK509 can work in pairing mode or non pairing mode. SK509 will work at pairing mode if it has been paired with any other SK509. Paired SK509 can only work with other paired SK509. It can’t communicate between paired SK509 and non paired SK509. For paired SK509, it is 2 way communication, the master can control the slave. Slave can control the master. But slave can’t control the slave and master can’t control the other master. In pairing mode, the status change of input (master or slave ) will synchronized to the output (paired slave or paired master ). If SK509 has not been paired with other SK509, or been unpaired, it works in non pairing mode. In non pairing mode, the change of input channel will synchronized to the same output channel in other side. ★ Application

www.nicerf.com SK509 NiceRF Wireless Technology Co., Ltd. Rev 1.5 sales@nicerf.com - 8 - a.How to pair the module 1. Power off the master and slave. 2. Pull the DIP6 to [OFF] side and DIP 5 to [ON] side 3. Power on the slave firstly , the alarm LED light on to indicate it is ready for pairing. 4. Power on the master , the pairing operation will start automatically, both alarm LED will light off when succeed pairing. 5. Pull both DIP6 of the master and slave to [ ON ] 6. Power off both the master and slave 7. Power on both master and slave for operation. b.How to unpair the module 1. Pull the DIP7 of the master to [OFF] side 2. Pull the DIP7 of the slave to [ON] side 3. Power off both the master and slave 4. Power on both master and slave for operation. 3) Timing working mode In timing mode, the module works in master mode or slave mode. The communication is one way. Communication is from master to slave. The master transmits the wireless signal to slave regularly, the corresponding relay of the slave will be synchronized after got the signal. The module can worked in fast mode or slow mode by changing the dip switch. The time interval of the fast or slow mode can be configured by PC software (default is 2s in fast mode, 30s in slow mode). The alarm LED will light on and all the four output relay will resume to 0（all relays are in open state）if no synchronized message received for continuous 5 times interval. The LED will indicate low battery and all the four output relay will resume to 0（all relays are in open state）if get low battery signal from the other side.

www.nicerf.com SK509 NiceRF Wireless Technology Co., Ltd. Rev 1.5 sales@nicerf.com - 9 - 4) Configuration mode: In configuration mode, user can configure the parameters by SK509-S or PC software. The configurable parameters include NET ID,16 groups frequency channels, inquiry time interval (only available in real time mode), master transmitting time interval(Only available in timing mode), modules can communicate with each other when parameters matched. PC software show as below：  CHANNEL Each module has 16 frequency channels, users can choose one of the channels to use via DIP switch, the corresponding frequency of the 16 channels can be modified via PC software. We suggest users using the default frequency value, or set the frequency value near the centre frequency to get better performance.  Inquiry Time This parameter is used in real time mode. The slave send the inquiry signal to master with this fixed inquiry time interval. 1 byte length, unit is minute, range is 1~30, count as 30 when over 30.  IDAddress This parameter is for configuring the ID address of the module, each module should have its unique ID address.  Time interval in timing mode It is for setting the time interval under the timing mode, unit is second. Default is 1s.

Application connection 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： 11. Accessories 1) Antenna The antenna is very important for RF communication, its performance will affect the communication directly. Module needs antenna in 50ohm. Common antenna has rubber straight/ elbow/ foldable rod and sucker antenna and etc. Users can order accordingly. To ensure module in the best performance, we suggest to use the our antennas. ★ To ensure modules get the best performance, user must obey the following principles when using the antennas：  Put the antenna away from the ground and obstacle as possible as you could；  If you choose the sucker antenna, pull straight the lead wire as possible as it can be, the sucker under arches should be attached on the metal object；
