[KBA-79176] Malfunctioning SAM ports and RS-485 COM ports on Synergis Cloud Link units equipped with the optional expansion module
After a firmware upgrade, the SAM card tab is missing from the Configuration section in the Synergis™ Appliance Portal, and doors with readers using decryption keys stored on SAM cards stop functioning properly. Readers and other RS-485 devices connected to the additional RS-485 ports from the expansion module are also affected because the RS-485 COM ports continuously disconnect.
Applies to
Synergis™ Cloud Link units equipped with an optional expansion module (SY-CLOUDLINK-312) after a Synergis™ Softwire upgrade from any version later than 10.6 to any version up to 11.5.0.
Cause
This is caused by an issue with the driver upgrade process of the expansion module.
Workaround
Status
This is resolved in Synergis Softwire 11.5.1.
