Front Panel LED Indicators & DIP Switch Setup

The IO-DAIO module is equipped with intuitive front panel LED indicators and built-in DIP switches for streamlined field operation.
The LED indicators provide real-time status feedback on power, communication, and relay output states, enabling users to verify system conditions at a glance.
DIP switches allow quick, tool-free configuration of communication parameters and node address directly on-site—simplifying setup and reducing installation time.

Power: Flashes to indicate the CPU is running.
RS485 Rx: Flashes to indicate the unit has received a valid Modbus message.
RS485 Tx: Flashes to indicate the unit has sent a Modbus message.
Dip Switch: Allows on-site configuration of address and baud rate.
