Issue
LED on card reader on ACX57xx (ACX2) flickers when it supposed to be solid green
Environment
- ACX57XX
- Some reader types from HID (such as I-class reader).
Cause
ACX57XX has new system variables added to get the status of reader connection to controller.(Rdr1Connected ~ Rdr8Connected).
In order to check the Status, ACX57xx checks the voltage presence on the LED channel of each reader port. This function causes the LED of some reader types to flicker at a high frequency.
Resolution
Set the Rdr1Connected ~ Rdr8Connected system variables to Disabled to keep the LED from flickering.
