Description: A good idea to be able to operate TypeA commissioning of 523 cards, the program may from 522 transplant. A card reading after two successful, first confirm the quality of the reader antenna under Before Reading B cards, including modulation amplitude modulation factor. Modulation amplitude is mainly C2 relationship with relatively large, the adjustment to be patient, to have around 10V modulation amplitude (unilateral) After adjustment under normal circumstances, with the size of the antenna and other factors are related. If there is a network analyzer that is the best thing. 14443 modulation factor according to the agreement is generally about 10 (8 -14 ), this should match the antenna to debug. Associated registers
