(*1)When a device with 32 stations is connected, its connection is counted as 2 devices, and the maximum number of connectable stations will decrease.
(*2)Addresses are set with a rotary switch.
In either MODBUS or RTU, please set the monitoring unit address within the range of 1-99.
If you set the address at "00", the network will be invalid.
