HF bus mode
In HF bus mode up to 32 bus-capable read/write heads per RFID channel can be connected to
the TBEN module. An additional power supply may be required depending on the number and
power consumption of connected read/write heads. A power consumption analysis of the
connected read/write heads is required in order to determine the additional power supply
required. A tool is provided at
for calculating the power.
Every connected read/write head supplies a “Tag present” signal in HF bus mode. HF bus mode
is suitable for static applications and very slow dynamic applications because a command can
only be processed by one read/write head at a time.
In Continuous HF bus mode, a command is performed simultaneously at all read/write heads in
a bus topology. The logged data is stored in the ring memory of the module.

HF bus mode supports the HF read/write heads from firmware version Vx.90.
Continuous bus mode supports HF read/write heads from firmware version Vx.93.
