To configure TLS settings without reconfiguring SSL, issue the TLSVERSION
command:
• Syntax: TLSVERSION [TLS1.0 | TLS1.2]
o TLS1.0: Implies that TLS 1.0 is the minimum version for TLS
connections
o TLS1.2: Implies that TLS 1.2 is the minimum version for TLS
connections
o No parameter: Displays the current setting
• Example: TLSVERSION TLS1.2
TLS/SSL certificates may also be managed using the SSL Management function
in Crestron Toolbox. For more information, refer to the Crestron Toolbox help file.
Server Certificates
When authentication is enabled, the control system uses a server-side certificate
to authenticate various control system components, including the web server.
One of the following three server-side certificate types may be used:
• A self-signed certificate that is generated by the control system
• A CA (Certificate Authority)-signed certificate and signing chain that are
loaded onto the control system
• An externally requested and signed certificate, signing chain, and private
key that are loaded onto the control system
Instructions for configuring each server certificate type are provided in the
sections that follow.
Self-Signed Certificates
To use a self-signed certificate with TLS/SSL:
1. Issue the SSL SELF command in the control system console.
2. Issue the reboot command to reboot the control system.
CA-Signed Certificates
The following procedures are used to obtain and load a CA-signed certificate to
the control system.
