2.3. Reader – Tag link profiles
A528 reader supports different modulation and return link profiles according to EPC
Class1 Gen2 protocol.
In the following table are reported all profiles that have been tested for the compliance
with ETSI and FCC regulations.
Link profile # Regulation Modulation Return Link
0 ETSI - FCC DSB–ASK; f=40kHz FM0; f = 40kHz
1 ETSI DSB–ASK; f=40kHz Miller (M=2); f = 160kHz
2 ETSI - FCC PR-ASK; f=40kHz Miller (M=4); f = 250kHz
3 ETSI PR-ASK; f=40kHz Miller (M=4); f = 300kHz
4 FCC DSB-ASK; f=160kHz FM0; f = 400kHz
5 FCC PR-ASK; f=40kHz Miller (M=2); f = 250kHz

2.4. Host communication interfaces
A528 reader allows the user to manage host communication through two different
protocols
5:
1. CAEN communication protocol.
In this case the host-reader interface is serial and A528 is fully compatible with
all the CAEN Demos and libraries included in the Easy2Read SDK.
2. Intel communication protocol.
In this case the host-reader interface is USB and A528 is fully compatible with
5
Serial / CAEN procotol is implemented starting from FW release 1.1.5.
