816 -* The command to active alarm is: 0A 05 00 04 00 01 **4C B0**. Where 0A 05 00 04 00 01 is the Modbus command to read the register 00 40 where stored the DI status. The 4C B0 is the CRC-16/MODBUS which calculate manually.
772 +* The command to active alarm is: 0A 05 00 04 00 01 4C B0. Where 0A 05 00 04 00 01 is the Modbus command to read the register 00 40 where stored the DI status. The 4C B0 is the CRC-16/MODBUS which calculate manually.
817 817  
818 -* The command to deactivate alarm is: 0A 05 00 04 00 00 **8D 70**. Where 0A 05 00 04 00 00 is the Modbus command to read the register 00 40 where stored the DI status. The 8D 70 is the CRC-16/MODBUS which calculate manually.
774 +* The command to deactivate alarm is: 0A 05 00 04 00 00 8D 70. Where 0A 05 00 04 00 00 is the Modbus command to read the register 00 40 where stored the DI status. The 8D 70 is the CRC-16/MODBUS which calculate manually.
819 819  
820 820  So if user want to use downlink command to control to RS485 Alarm, he can use:
821 821  
822 -(% style="color:#037691" %)**A8 01 06 0A 05 00 04 00 01 00**(%%): to activate the RS485 Alarm

780 +**A8 01 06 0A 05 00 04 00 00 00**: to deactivate the RS485 Alarm
825 825  
826 826  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.
