Page 14: Functional Overview
Processing Unit (CPU). Functional Block Diagram The Medio S001/S002 architectural structure is based on a CPU that drives all reader functions. It manages communications between the host system (connected to the “Reader-to-Host interface”) and one or more smart labels using an antenna (connected to the “Tag-to-Reader interface”). -
Page 15: Communication Protocols
Medio S002 Only 3.2.2 Reader-to-Host Interface When the Medio S001/S002 reader is connected to an antenna, it acts more as a protocol converter due to the wide range of tasks it can perform. For more information about these tasks, refer to the Medio S001/S002 Command Set document. -
Page 16: Signal Detection Module
The Reader-to-Host interface is independent from the host system. Stand-alone mode is used by the Medio S001/S002 reader to read tags and send their identification data to the host system. This transmission takes place in ASCII format. While in this mode, the reader cannot receive any commands. -
Page 17: Peripheral Devices
Even if the RF is turned off, these commands activate the RF field. When the task has been performed, the RF field either reverts to its initial state or stays on depending on the command. Please refer to the Medio S001/S002 Command Set document for command-specific RF management information. -

In any event, the SHDW pin voltage must not exceed 6V. Antenna The J2 connector is dedicated to an antenna that is required for reading smart labels. This can be a TAGSYS antenna or a custom-made model. The choice of the antenna must take into account the following considerations: •... -
Page 21: Serial Communication Links
The communication type is selected using the “Serial Communication Select” command (please refer to the Medio S001/S002 Command Set document). The RS-232 link is the default setting. In any case, the TTL interface is always active and has priority over any Recommended Standard (RS) communication connection. -

Page 27: Installing The Rs-485 Half Duplex Interface
Serial Communication Links A 120-Ohm resistor should be added at the end of the two transmission lines in compliance with RS-485 specifications. When set to communicate using the RS-485 interface, the reader always holds the transmission lines before the start of any communication and returns to Tri-state mode at the end of communication. -

Medio S001/S002 Reader Integrator's Guide reference may be established by a third conductor connecting the common leads of the devices, or it may be provided by the connection from each equipment item to a ground reference. Where the reader reference is provided by a third conductor, the connection between the reader common and the third conductor must contain a certain amount of resistance (e.g. -
Page 29: Connecting Peripheral Devices
Connecting Peripheral Devices 6 Connecting Peripheral Devices Using the Input / Output Pins (I/Os) Each I/O pin can be used as either an input or an output. Its voltage is compatible with the TTL/CMOS level. By default, all pins are set as inputs at each power-on reset. When set as input, each pin features a high impedance state to a TTL input buffer and has an internal pull-up resistance of 10 kΩ. -

• Medio S002 and Medio S001 Rev. 2: Connection optional for Stand-alone mode. Connection not required if Medio S002 or Medio S001 Rev. 2 is set in Stand-alone mode using the “Set Stand-alone Mode” command. If an STX-E command is used to enter Standalone mode, the RX_XXX link can be connected allowing the user to exit Standalone mode by sending the 'S' character. -
Page 38: Disabling Stand-Alone Mode
Disabling Stand-alone Mode 7.4.1 Medio S001 To reset the Medio S001 in Standard mode: 1. Turn off the reader. 2. Remove the connection between pins RX_TTL and TX_TTL. 3. Turn on the reader. - Page 39 Stand-alone Mode This function is only available with Firmware version 2.4 or more recent. When exiting Standalone mode using this command, note that the response time varies in function of the current Medio S002/S001 Rev. 2 activity (tag reading in progress, for example).
