1 Control commands:
 
 
 
1. Reading status(reading the satus of the relay (on/off))
 
 
 
0x55 0x56 0x00 0x00 0x00 0x00 0x00 0xAB
 
 
 
 
 
2.Relay open (issue this command,Relay open,COM connect to NO)
 
 
 
Channel 1 : 0x55 0x56 0x00 0x00 0x00 0x01 0x01 0xAD
 
Channel 2 : 0x55 0x56 0x00 0x00 0x00 0x02 0x01 0xAE
 
 
 
 
 
3. Relay close (issue this command,Relay close,COM disconnect NO,and COM connect to NC)
 
 
 
Channel 1 : 0x55 0x56 0x00 0x00 0x00 0x01 0x02 0xAE
 
Channel 2 : 0x55 0x56 0x00 0x00 0x00 0x02 0x02 0xAF
 
 
 
 
 
4. Relay toggle(Relay status reversal,if COM connect to NO,this commands will Disconnect COM to NO and Reverse COM connect to NC,and vice versa)
 
 
 
Channel 1 : 0x55 0x56 0x00 0x00 0x00 0x01 0x03 0xAF
 
Channel 2 : 0x55 0x56 0x00 0x00 0x00 0x02 0x03 0xB0
 
 
 
 
 
5. Relay momentary(Relay COM connect to NO,disconnect after 200MS)
 
 
 
Channel 1 : 0x55 0x56 0x00 0x00 0x00 0x01 0x04 0xB0
 
Channel 2 : 0x55 0x56 0x00 0x00 0x00 0x02 0x04 0xB1
 
 
 
 
 
Once issue a command,will have a return fame,7th byte of return fame mean the satus of realy.
 
 
 
2 return command
 
 
1.Return relay open(return this command,mean COM connect to NO)
 
 
 
Channel 1 : 0x33 0x3C 0x00 0x00 0x00 0x01 0x01 0x71
 
Channel 2 : 0x33 0x3C 0x00 0x00 0x00 0x02 0x01 0x72
 
 
 
 
 
2.Return relay close(return this command,mean COM disconnect NO , and COM connect to NC)
 
 
 
Channel 1 : 0x33 0x3C 0x00 0x00 0x00 0x01 0x02 0x72
 
Channel 2 : 0x33 0x3C 0x00 0x00 0x00 0x02 0x02 0x73
