CK721-A System Specifications (All Panels)
System Configuration Example
NOTE: Each network device must have a unique IP address because the performance of an entire
network can be compromised if two devices share the same address.
Figure 1: Example of a Simple CK721-A System Configuration
CK721-A Encrypted Communications with the Server
When enabled, encrypted network communications between the CK721-A controller and the server
uses the Advanced Encryption Standard (AES256).
The CK721-A Encryption is implemented using the Federal Information Processing Standards (FIPS)
140-2, validated (Certificate #2398), cryptographic module (version 2.0.9) from the Open Source
Software Institute (http://www.oss-institute.org
).
CK721-A controller peer-to-peer User Datagram Protocol (UDP) broadcast messages are not
encrypted.
