Reloading Factory Defaults
To reload Factory Defaults, press and hold the Mode switch for more than 10 seconds.
The LED indicators respond as follows:
1. The Ready LED blinks three times per second while the button is being pressed.
2. The Modbus gateway is in Factory Default Mode when:
• On the MESR901: Port 1 LED and the Ready LED are both On.
• On MESR902x models: Port 1 LED and the Port 2 LED are both On.
The Modbus gateway reloads all factory default configuration parameters.
3. The LEDs go back to their normal states when the device resumes normal operation.
