5.5 Continuous HF bus mode — Data retrieval
All activated read/write heads are triggered within a time frame of bypass time + 10ms. Within
this time frame, the set command (e.g. inventory, read, write) is processed in Continuous mode.
While a command is being executed by all activated read/write heads, only one read/write
head sends data to the RFID interface. The other read/write heads store the read data for sub-
sequent retrieval. When a new tag is detected by the same read/write head, any data in the buf-
fer of the read/write head that has not yet been transferred to the RFID interface is overwritten.
During the time between two requests and when sending data to the RFID interface, the read/
write heads do not recognize any tags. The required waiting times are given in the following
table:
Command Waiting time
Inventory 15ms
Read 25ms
Write 35ms
By default, the bypass time in HF bus mode is 48ms.
The following table shows when commands are executed (CMD) and data is exchanged (DATA).
n CMD: Command is being executed.
n DATA: Data is being exchanged.
n DATA or CMD: If data is stored on the read/write head, the data is sent to the TBEN module. If
no data is stored on the read/write head, the command is executed.

5.6 LED displays on read/write heads in HF bus mode
In HF bus mode, the LEDs on the read/write heads have the following display functions:
LED Condition Function
Green Flashes 3x, 0.5-s break
(recurring)
Incorrect read/write head address or no
read/write head address assigned
Flashing (1Hz) Read/write head not activated
The yellow LED has no specific function in HF bus mode.
