We recommend a specific firmware version for each generation of HID controllers, old (Legacy) and new (EVO). Using earlier firmware versions might cause issues with your system.
|Supported firmware||Legacy controllers||EVO controllers|
|Recommended certified firmware||188.8.131.528||3.8.01|
|Minimum supported firmware||184.108.40.2068||3.5.x|
1As of Security Center 5.8, HID units running firmware version 220.127.116.11 or later in secure mode communicate with the Access Manager using TLS 1.2 encryption over TCP port 4433. HID units running an earlier firmware version or in regular mode communicate with the Access Manager using HID encryption.
For more information about port changes, see Firewall ports used by Synergis™ applications in Security Center.
