Too often people walking around in a server room do not have instant access to a browser to view the latest information of their monitoring status. If they want to know it then they had 2 options until now:
- connect to the webserver using a mobile device or PC
- send a SMS message to the software

The LCD displays are manufactured by Crystalfontz. They connect through USB to the device running the Monitoring Software. Just configure the USB COM port in the software to which the display is connected to and restart the monitoring service.
