WARNING!
SIGRIST instruments are equipped with an integrated web user interface and Mod-
bus TCP interface, thus offering state-of-the-art administration and control possibil-
ities. However, if these are connected directly to the Internet, then any Internet us-
er can in principle access your instrument and change the configuration.
Please note the following points to prevent this:

Never connect the instrument directly to the Internet.

Operate it behind a firewall and block access to the instrument.

Only connect to branch offices via VPN.

Change the standard password on commissioning.

Always keep up to date with the latest changes regarding Internet security so that you
can react promptly in the event of alterations.

Install the latest updates immediately (also for the router and firewall).
