- You can set the station No. to "FF" to transfer the command to all stations simultaneously. Note that ACK or NAK response will not be performed. In this case, please set the interval of 100ms or more until sending next command after sending the first command.

- You can allocate the station No. to the address.
  Please store station No. in the address to be allocated.
  When a command receipt is completed, the destination station No. on the command and the data stored in the address are compared.
  When the value stored is 0 to 31, the station No. is processed as the stored value. When the value is 32 to 65535, only the broadcast command (the destination station No. is FF) is processed.
