4.4 Architecture of the Included Long Range Reader
TAGSYS conveyor tunnel reader includes a Medio L200 Tunnel long range reader.
The 4 I/O reader ports are used to manage the stacklight indicator and trigger reading operation.
The Reader consists of two main parts: the Radio Processing Unit and the Data Processing Unit.
The Radio Processing Unit (RPU) manages the communication with the tags. This includes the
channel multiplexing management, RF output power levels and tag decoding. This part is built
around a high-performance Digital Signal Processor (DSP). Depending on the product reference,
the specific firmware associated to the DSP is downloaded into the DSP Flash memory. For more
details concerning the RPU architecture, please refer to the Lx00
Full Firmware Reference Guide.
The Data Processing Unit (DPU) consists of the GemCore
®
OS. The DPU controls the serial
communication link, I/O ports, and commands sent to the DSP. Custom application software can
be downloaded into the DPU. The standard application software is the TAGSYS STX-E
communication protocol.

For set up, debug or monitoring purpose, the Host PC communicates directly with the DSP via the
Monitoring port. When the Monitoring port is in use, the DPU block (I/O ports and serial
communication link) is disabled.
4.5 TAGSYS Conveyor Tunnel Reader Connections
4.5.1 Serial Connector
The DB9 serial connector on the electrical cabinet is used to communicate with an external
environment (host PC).
In standalone mode, this port transmits tags data to the host PC (Please refer to chapter
4.1).
