3.3.
3.3.1.
This command reads the serial number of a HITAG 1 transponder in “Standard Protocol Mode“.
Protocol:
Host - Reader module
Reader module - Host
3.3.2.
This command reads the serial number of a HITAG 1 transponder and switches the transponder
into “Advanced Protocol Mode“. The transponder now responds on all commands in the
“Advanced Protocol Mode“. This mode can only be left by an “power on reset“ of the transponder
(use “HF_OFF“ or “Power Down“ command or move the transponder out of the antenna field).
The “Advanced Protocol Mode“ is not left by using the “GetSnr_HT1“.
The major difference between “Standard Protocol Mode“ and “Advanced Protocol Mode“ is in-
creased data reliability during data transmission from the transponder to the reader by using an 8
Bit CRC and a longer start sequence.
The “Advanced Protocol Mode“ is not supported by transponder version HT1 ICS30 0
only by version HT1 ICS30 0
Protocol:
Host - Reader module
