NOTE: If you connect the PC to the LES301A, make sure that the PC is in the same subnetwork as the LES301A.
3. Connect the LES301A‘s serial port to a serial device.
NOTE: You may need an adapter (LES30X-TB5) for RS-485 or RS-422 applications.
4. You can mount the LES301A to a wallplate (mounting screws are included) or a DIN rail using the DIN rail kit (LES30X-DR).
