5.3.4 T5557/ATA5567 Multifunction Read/Write Transponder
The ATA5567 offers an improvement over T5557’s slow power-on behavior. Apart from this difference,
both transponders are functionally identical and thus can be managed by same user interface. Both tran-
sponders are backward compatible to the older T5551/TK5551 version. Therefore, they can be operated
in the Compatible or Basic Mode.
