Secure Sockets Layer (SSL) Certificates

Extron control processors and expansion interfaces ship with factory‑installed SSL
certificates created by Extron. If you want or are required to use a different SSL certificate at
your installation site, then you can use system utilities in the Toolbelt software to change the
SSL certificate at any time. The Toolbelt Help File provides instructions on how to apply an
SSL certificate to a control processor.
NOTES:
Control system expansion interfaces and controllers support standard OpenSSL certificate
encodings such as .pem (Privacy‑enhanced Electronic Mail) and .der (Distinguished
Encoding Rules) file types. PEM file types are ASCII encoded and are the required format for
uploading to the control processor. DER file types are binary encoded and can typically have
several file extension variations, such as .crt and .cer. There are many standard tools that
can convert from DER to PEM file encodings if needed.
NOTE: A DER format file must be converted to PEM encoding before uploading it to the
To properly create the certificate for uploading to Extron expansion interfaces and control
processors, ensure that the certificate file meets the following requirements:

Contact your IT administrator for more information on what tools and policies are required to
obtain or create the SSL certificate and, if necessary, the corresponding passphrase.

IEEE 802.1X Certificates

IEEE 802.1X is a standard that enables port‑based network access control via an
authentication server. The protocol requires that all devices must be authenticated before
gaining privileges to access the secure part of the network.
