  **Example 1:**
  To connect a Modbus Alarm with below commands.
--* 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.
++* 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.
--* 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.

  So if user want to use downlink command to control to RS485 Alarm, he can use:
--**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 01 00**(%%): to activate 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.
