Hitag 2 Configuration Byte
The 8 bit configuration byte located at the start of page 3 defines the basic mode of the Hitag
2 transponder and whether certain parts of it’s memory are locked or open for Read/Write
operations. Note that the MicroRWD H2 only supports PASSWORD mode and can
communicate with Hitag 2 tags with the configuration byte = 0x06 (or 0x46 with
configuration and TAG Password locked).
CONFIGURATION OR PASSWORDS MUST NOT BE CHANGED UNLESS THE
OPERATION OF THE HITAG 2 TRANSPONDER IS UNDERSTOOD.

Micro RWD (EM) H400x / 4102 Protocol
The MicroRWD H400X Reader mode is a complete reader and tag acceptance solution for
EM Marin H4001/H4102 and compatible RFID transponders.
Read H400x Tag
Command to read 5 bytes of data from H400x (40 bit) memory array. If the read was
successful, indicated by acknowledge status flags then five bytes of tag data follow.

(D = msb data read from H400x)
(D = lsb data read from H400x)
Note that for the Read Tag command, if an error flag has been set in the Acknowledge code
then there will be NO following data.
