Application Note 25 – Using the Model 6055B HID Mifare Reader  
Page 8  
In transaction mode, every function of the reader is under the complete control of 
the connected PC or controller.   
 
The reader will assert the DTR control line when it successfully reads a card.  
This alerts the host that a card has been read, and can be used to trigger the 
customer’s application program.  The reader continuously re-transmits the CSN 
until an acknowledgement is received from the host.  The reader also sends a 
“break” signal when it powers up.  If the developer is using non-standard keys for 
his application, this allows the application to resend the keys (only the default 
keys are stored in Flash memory).
