After updating the Java version to 8update481, CCKM couldn't find and add KX9970, KX9980, and other KE transmitters and receivers.

The Tx and Rx that have already been added to the CCKM become offline.  What's the reason?

It's because the Java change its security setting in 8update481.  Please disable delete the words "TLS_RSA_*," in java.security, below is the process.

1. Go to the service list and stop the CCKM service.  The service name is "KVM over IP Matrix Manager service".

3. Copy the file "java.security" and put it to the desktop.

4. Change the file name of the java.security to java.security_old.  Here please change the file in the path C:\Program Files\Java\jre-1.8\lib\security

5. Go to desktop and open the java.security to delete the "TLS_RSA_*,".  You could search the keyword below to find out the location.
