Function Description Module can work in the following two modes A.real-time working mode In real-time mode, the module will monitor the four input port status,after status changes, wireless signals will be sent immediately,then in Rx side the corresponding relay status will be synchronized after receiving the signal.Show as below:
Also in this mode,the slave will regularly send inquiries to the master for link status.If no acknowledged signal come to the master,the alarm LED will light on,after the inquiry time is over and all the output relays will be resumed open. B.Timing mode In timing mode,the master regularly transmits the signal of the input state,If the slave has not received the master\' s signal 5 times interval ( fast/slow time), the LED will light on,and all the output relays will be resumed open. C.Configuration mode In configuration mode,user can configure the parameters by PC software/UART command/ remote controller SK108-S.The diagram of PC software is shown below:
