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 :33 3C 00 00 00 01 01 71
Channel 2 :33 3C 00 00 00 02 01 72
Channel 3 :33 3C 00 00 00 03 01 73
Channel 4 :33 3C 00 00 00 04 01 74
 
2.Return relay close（return this command,mean COM disconnect NO , and COM connect to NC ）
Channel 1 :33 3C 00 00 00 01 02 72
Channel 2 :33 3C 00 00 00 02 02 73
