Ecler White Paper Networking

This device is a software application used for the configuration and control of the Ecler networkable devices family (MIMO88, NZA series, NPA series, etc.). It uses an Ethernet LAN network as the physical infrastructure to establish the communication link with the devices under its management.

This application has several capabilities, including:

Configuring and controlling Ecler networkable devices
Discovering unused compatible devices on the network
Troubleshooting network issues
Controlling devices remotely over the internet

You can use this device for a variety of purposes, such as:
