SRTAG2K-D

RF command sets

5.1

Structure of the command sets

The exchange of data between the RF host and the SRTAG2K-D uses three kinds of data

formats, called blocks:

•

I-Block: to exchange the command and the response

•

R-Block: to exchange positive or negative acknowledgement

•

S-Block: to use either the Deselect command or the Frame Waiting eXtension (WTX)

command or response

This section describes the structure of the I-Block, R-block and S-Block. This format is used

for the application command set.

5.2

I-Block format

The I-Block is used to exchange data between the RF host and the SRTAG2K-D. It is

composed of three fields. Table 10 details the I-Block format.
