Epson EB-2247U User Manual

Secure HTTP
103
You can use the HTTPS protocol to increase security between the projector
and a Web browser communicating with it (EB‑2247U/EB‑2142W). To do
this, you create a server certificate, install it on the projector, and turn on the
Secure HTTP setting in the projector menus to verify the reliability of the
Web browser.
s Network > Network Configuration > Others > Secure HTTP
Even if you do not install a server certificate, the projector automatically
creates a self-signed certificate and allows communication. However, because
the self-signed certificate cannot verify reliability from a Web browser, you
see a warning about the server's reliability when you access the projector from
a Web browser. This warning does not prevent communication.
