19 Components and Operation – Chapter 5
The protocol is adjustable, irrespective of whether telegrams are put out permanently by an
adjustable update rate or whether one transponder is located within the field.
Table listing the data words of a telegram of 12 (13) byte length:
The following table shows a list of the binary codes used to describe the system status (for
bytes # 11 and 12 from Table 6):

– *) Is deleted, as soon as voltage and frequency correspond to the specifications.
– **) The values for code, Us and Ud equal the saved values. The bit remains set until
the next test and is deleted by unsuccessful reference transponder test.
– ***) These bits are deleted as soon as the transponder leaves the antenna field.
– ****) Is deleted at the first call of the reference transponder test.
