Gateway to Sound Level Meter

The XL2 Sound Level Meter gets connected by the accessory NetBox to the internet. A connection is possible via mobile, LAN or Wi-Fi communication. This allows SFTP (Secure File Transfer Protocol) and remote COM port access to the XL2. The setup is plug-and-play.

Internet FTP Access to the XL2 is practical for both short-term noise assessments and long-term monitoring applications. The recording of spectral data, 100 ms data logging, and event audio can be set up on the XL2. The resulting log files can then be retrieved remotely during a running measurement.
