  So if user want to use downlink command to control to RS485 Alarm, he can use:
--(% style="color:#037691" %)**A8 01 06 0A 05 00 04 00 01 00**(%%): to activate the RS485 Alarm
++**A8 01 06 0A 05 00 04 00 01 00**: to activate the RS485 Alarm
--(% style="color:#037691" %)**A8 01 06 0A 05 00 04 00 00 00**(%%): to deactivate the RS485 Alarm
++**A8 01 06 0A 05 00 04 00 00 00**: to deactivate the RS485 Alarm
  A8 is type code and 01 means add CRC-16/MODBUS at the end, the 3^^rd^^ byte is 06, means the next 6 bytes are the command to be sent to the RS485 network, the final byte 00 means this command don’t need to acquire output.
