Description
When you test the product with an oscilloscope, you will find that the frequency of this device is 125khz.Replacing 134.2khz with 125khz to read FDX-B is a low-cost solution.if your tag is not FDX-EM4305 please choose other module.

* The results of the test are for reference only
For example, the 16 binary data of animal labels are: 03 84 12 DB FA E7 D5
(Country ID:03 84, National ID:12 DB FA E7 D5)
Serial port protocol: AA 0F 08 00 03 84 12 DB FA E7 D5 81 BB
AA is the starting code;
0F 08 00 (the three data is fixed)
03 84 12 DB FA E7 D5 (animal label data)
B1 (exclusive or check code)
BB (end code)
Check code:0F(XOR)08(XOR)00(XOR)03(XOR) 84(XOR)12(XOR)DB(XOR) FA(XOR)E7(XOR)D5=81
