LED on card reader on ACX57xx (ACX2) flickers when it supposed to be solid green

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.
