Module size: long66mm  wide65mm   high20mm


Instruction format:
FF 01 00 01 EE
① ② ③ ④ ⑤

  Instruction parsing:
①【FF】: Instruction head
②【01】: First road relay(01 by1 road.02 by2 road, Analogous... 25 The representative controls all the relays)
③【00】: This position is00 time, Relay disconnection; by01 Time relay closure;02 When1 Second point motion( That is to get through1 Disconnection after a second); For other values, Relay does not move.
④【01】: This bit is a check code, For the first two places②+③ And( In this Directive01+00=01).
⑤【EE】: Instruction tail

 

If you don't understand the above analysis, look at the detailed instruction set below.:

//====== Instruction description======//
//FF 01 00 01 EE ----> The first road closes
//FF 01 01 02 EE ----> The first way open
//FF 01 02 03 EE ----> The first road1 Second point motion( Connect1 Second and then break, Advance contact instructions that need to be modified for time, Thank you!)

//FF 02 00 02 EE ----> Second road closes
//FF 02 01 03 EE ----> The second way open
//FF 02 02 04 EE ----> Second road1 Second point motion( Connect1 Second and then break, Advance contact instructions that need to be modified for time, Thank you!)

//FF 03 00 03 EE ----> Third road closes
//FF 03 01 04 EE ----> The third way open
//FF 03 02 05 EE ----> Third road1 Second point motion( Connect1 Second and then break, Advance contact instructions that need to be modified for time, Thank you!)

//FF 04 00 04 EE ----> Fourth road closes
//FF 04 01 05 EE ----> The fourth way open
//FF 04 02 06 EE ----> Fourth Road1 Second point motion( Connect1 Second and then break, Advance contact instructions that need to be modified for time, Thank you!)

//FF 25 00 25 EE ----> close all
//FF 25 01 26 EE ----> All open

//====== Query relay status command===========
//FF 26 00 00 EE ----> Query relay status

// After sending the command, The module will output a sixteen decimal number to the serial port
// After converting to binary numbers, the following is shown:
//0 0 0 0 X    X   X   X
//        ④  ③  ②  ①
// High four bits0,
//①=0, The first way is to disconnect;①=1, It shows that the first way is closed..
//②=0, It shows that the second way is disconnected;②=1, It shows that the second way is closed..
//③=0, It shows that the third way is disconnected;③=1, It shows that the third way is closed..
//④=0, It shows that the fourth way is disconnected;④=1, It shows that the fourth way is closed..
