5.1.5  Configuring Permanent read 
If lots of transponders have to be read in a short time, permanent read mode is a useful tool. 
In this mode reading transponders takes place until timeout reached or read button is pressed. 
After successful read of a transponder, timeout will be reset. 
To prevent parts of the Stick Reader from overheating break time must be greater than 450 
times number of reads. 
Reads is the number of reads in one burst. The number of bursts is the timeout before perma-
nent reading stops. Break is the break time in ms between two burst. 
In this example two reads are in one burst. That means a minimum break time of 900 ms is 
necessary (in this example 1000 ms is chosen). 
The number of burst is 10. 
Timeout is calculated as follows: 
Timeout = (Number of reads * reading time + break time) * number of bursts 
One read takes approximately 90ms. 
   
Timeout = (2 * 90ms + 1000ms) * 10 = 11800 ms 
In this case timeout is approximately 12 seconds. 
To configure and enable permanent reading mode fill in the values into the corresponding input 
fields, mark the checkbox Active and press the corresponding Set pushbutton.
