Filter Commands

Each read or write command can access one, several, or all tags in a measurement range. The
process is controlled by filter masks, which are managed via the commands Set Filter Mask
(FI) and Activate/Deactivate Filter (MF). These commands allow you to detect specific tags in
the measurement range. see chapter 6.5.
Set Filter Mask FI
Using command FI, you can define a filter mask for accessing the tags located in the box. You
can define up to 3 filters (0-2). The following syntax is used:
Command:
Response:
<MemBank> = Memory segment to which the filter is to be applied. The information is entered
as one hex
<StartAddress> = Address of the bit at which the filter mask begins. Specified in hex
Values: 0000
<MaskLength> = Length of the mask in bits. The information is entered as 2 hex
characters.
<MaskData> = Defines the actual filter mask
Example:
There are three tags in the measurement range of the read/write head. Each tag has a unique
identifier of <PC> & <UII/EPC>:
1. Tag
2. Tag
3. Tag
If you want to detect the 3rd tag, the filter mask is: FI101000001028.34.00.E2.00.90
