Information on Infinity System Variable named Rdr1Connected through Rdr8Connected
Resolution
The Infinity System Variables — Rdr1Connected, Rdr2Connected, ..., Rdr8Connected — are used to determine the connection status of card readers on specific controller models.
Functionality:
- These variables return a Boolean value (true or false) indicating whether a card reader is connected to each respective channel.
- The controller checks the connection by monitoring the voltage applied to the reader.
- LED1 is used as an indicator:
- If LED1 is correctly connected, the corresponding RdrXConnected variable is set to true.
- If not, it is set to false.
Note:
The voltage check may cause the LED to flicker at a high frequency. This flickering is typically not visible to the human eye.
