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

Command analysis:
① [FF]: Command head
② [01]: The first relay (01 to 1 channel, 2 channel 02, and so on ... 25 representatives control all relays)
③ [00]: This bit is 00, the relay is switched off; it is 01 relay closed; 02 when one second jog (ie, one second after turning off); another value, the relay does not operate.
④ [01]: This bit checksum for the previous two ② + ③ and (this Directive 01 + 00 = 01).
⑤ [EE]: Instruction end


The above analysis can not read, then you see the following detailed set of instructions:

// // ====== ====== Instruction Description
FF 01 00 01 EE ----> first relay closed
FF 01 01 02 EE ----> first relay open
FF 01 02 03 EE ----> first relay one second jog (on 1 second and then off, you need to modify the time in advance, thank you!)

FF 02 00 02 EE ----> second relay closed
FF 02 01 03 EE ----> The second way to open
FF 02 02 04 EE ----> 1 second point of the second path move (on 1 second and then off, you need to modify the time in advance, thank you!)

FF 03 00 03 EE ----> Third relay close
FF 03 01 04 EE ----> third way open
FF 03 02 05 EE ----> 1 second point of the third way move (on 1 second and then off, you need to modify the time in advance, thank you!)

FF 04 00 04 EE ----> fourth relay closed
FF 04 01 05 EE ----> fourth relay open
FF 04 02 06 EE ----> fourth relay one second point move (on 1 second and then off, you need to modify the time in advance, thank you!)

FF 25 00 25 EE ----> All Off
FF 25 01 26 EE ----> fully open

// ====== =========== Inquiry relay status command
EE FF 26 00 00 ----> relay status inquiry


// Send command is sent after the investigation, the module will output to the serial port of a hexadecimal number
// After convert the binary number is as follows:
// 0 0 0 0 XXXX
// ④ ③ ② ①
high four // 0 ,
// ① = 0, described the first path is disconnected; ① = 1, description of the first path is closed.
// ② = 0, illustrating a second path is open; ② = 1, illustrating a second road is closed.
// ③ = 0, described the third way is open; ③ = 1, illustrates a third road is closed.
// ④ = 0, a fourth path is disconnected; ④ = 1, a fourth road is closed.
