Epson EB-1785W User Manual

Secure HTTP
105
You can use the HTTPS protocol to increase security between the projector
and a Web browser communicating with it
(EB‑1795F/EB‑1785W/EB‑1781W). 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.
