SRTAG2K-D

RF command sets

5.2.2

R-APDU: payload format of a response

the SRTAG2K-D uses the I-Block format to reply to a command which used the I-Block

format. This format is described in Table 13.

5.3

R-Block format

The R-Block is used to convey positive or negative acknowledgment between the RF host

and the SRTAG2K-D.

There are two kinds of R-Blocks:

•

R(ACK): the acknowledgement block sent by the RF host or by the SRTAG2K-D

•

R(NAK): the non-acknowledgement block sent by the RF host or by the SRTAG2K-D
