Note_1: The 3rd and 4th byte are relay addresses. So CH1~CH4 can be 0x0003, 0x0008, 0x000D, 0x0012.

Note_2: The 10th and 11th byte are delay time in second. The minimum delay time is 0.1s. The relay will OFF after delay time. So the delay time in this command is: 0x0014*0.1=2S.

17. Turn OFF CH_1 Relay(3S Flashing Mode):

xa0 xa0 xa0Send: FF 10 00 03 00 02 04 00 02 00 1E A5 99
