1 Control commands：
1. Reading status（reading the satus of the relay (on/off)）
55 56 00 00 00 00 00 AB
2. Relay open (issue this command ，Relay open , COM connect to NO ）
Channel 1 ：55 56 00 00 00 01 01 AD
3. Relay close (issue this command ，Relay close , COM disconnect NO , and COM connect to NC ）
Channel 1 ：55 56 00 00 00 01 02 AE
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 ：55 56 00 00 00 01 03 AF
5. Relay momentary（Relay COM connect to NO，disconnect after 200MS ）
Channel 1 ：55 56 00 00 00 01 04 B0
6. Relay Interlock
Channel 1 : 55 56 00 00 00 01 05 B1
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
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
