1. Simple reading of the antenna with 3 input bytes according to the following table
2. Read antenna with 3 input bytes (Table 7) and send delete statement with one
output byte (Table 8)
The output byte has to be applied according to the following table:
If a new positioning pulse shall be released at the transponder just read, e. g.
after a change in the direction of travel, the delete statement has to be send.
This instruction sets the number of the last read transponder to zero. The delete
statement will be initiated by a rising edge of the CLR-bit; i. e. first the status
byte should be transferred with a deleted CLR-bit. The current status will be indi-
cated in the status byte (see Table 11 on page 12).
