1. Data is sent from the host computer.
2. Data from the computer is received at each inverter and the inverter numbers are checked.
3. When "*" is added to the position of an inverter number, it is judged a broadcast. The

command is decoded and processed.
4. To prevent data conflicts, only inverters where "*" is overwritten to "0" can reply with data to

the host computer.
5. As a result, all inverters are operating with the broadcast operation frequency command.
Specify inverter numbers by group for group broadcasts.
This is a function only for ASCII mode. For parity mode, refer to RS485 Communications
Function Instruction Manual (E6582143).
For example, when "*1" is set, inverters "01", "02", "03", "04", ..., "09" can be broadcast to.

In this case, the inverter specified as "01" can reply.
■ Connection example of inverter-to-inverter communication
One inverter is a leader and the other inverters are followers.
Here is a case where all follower inverters connected operate at the same frequency as the leader
inverter.
No frequency point is set.
