This is an adapter used with the Zed-FULL/Zed-FULL plus to read 64-pin processors after desoldering them for a range of applications. These applications include certain Eeprom-MCU modules (specifically modules 2, 10, 12, 71, 104, 132, 136, 143, 144, and 239) and some Mercedes-Benz Smart key programming applications (W203, W215, W220, W639).
For the Mercedes-Benz Smart key programming applications, the ZFH-EA10 and ZFH-EA9 adapters can also be used for the same purpose.
