5.2.1 Read data
Configure here which tags should be selected, how to access these tags, what data should be read from these tags and
if a security check should be performed.
By default, the reader is configured to select ANY TAG and read its EPC number.
Select NEDAP to read only Nedap tags.
NEDAP DUAL-ID enables the uPASS to search for Nedap vehicle-id tags. When a vehicle-id tag is found, the uPASS
searches for driver-id tags.
Example 1 - Nedap
Read only NEDAP UHF tags:
Figure 10: Read data example 1
Example 2 - Custom
Read only tags with EPC number starting with 99 and read 4 words from user memory. Note that the bit pointer is set to
32 because the EPC memory bank starts with 16-bits CRC and 16-bits PC (protocol control). Therefore the EPC number
starts at bit pointer 32.
