Reader Configuration

Present the card face-on to the reader until you hear a "bleep". Cards can be presented in rapid succession;
there is no

 

need, for example, to wait for "UNLOCKED" to disappear before presenting another.

If the reader has been enabled for user-code mode at the controller, you can gain access by pressing the # 
key, entering your card number, then pressing the * key.

The reader supports the first two different card types/formats presented after power-up. For example, 
encoded MIFARE and encoded MIFARE DESfire (in this example, unencoded cards would not be 
recognized). The reader enters this configuration mode whenever power is re-applied. 

A reader Setup menu can be displayed by pressing the * and # keys simultaneously while power is 
applied. You can use the menu to change the contrast and language used for the LCD (default English), 
and view the two card types/formats previously programmed. At the prompts, press * for No and # for Yes.
