They also demodulate signal from tags for downlink communication and provide monitoring information such as operating temperature and antenna tuning status. They are controlled by the Radio Subsystem.  The IO Front End is responsible for providing 4 protected digital inputs and 4 protected digital outputs. It is controlled by the Radio Subsystem and can be used as general purpose IOs directly accessed by the host system, or to automatically trigger readings and signal reading activity (by light stacks for example) without intervention from the host system.  The Radio Subsystem is responsible for managing the RF and IO Front Ends, encoding and decoding signals to/from tags, filtering tag data (for example removing duplicate reads) and providing RFID-related primitives to the Microsystem (like “Activate channel 1”, “Set output power to 1 Watt”, “Read UID from ISO15693 tag”, …). It is DSP based and is controlled by the microsystem.  The Microsystem is responsible for interfacing the Radio Subsystem to the host system through various physical interfaces (USB, RS-232, 10/100 Ethernet) and protocols (Tagsys StxNG protocol, standalone mode, telnet server, serial console and heartbeat). It also controls the LCD and keypad.
Medio L400 38/51 Revision 1.6 March 2008 5.2 Reader to Host Protocols 5.2.1 TAGSYS StxNG TAGSYS StxNG is the protocol used by the Medio L400 reader to communicate with the host system. Upon start up, the Medio L400 reader starts listening for incoming frames over all of its interfaces:  USB (seen as a virtual COM port from the host side)  RS-232  Primary and Secondary TCP ports (default ports are ports 4000 and 4001. Only one connection per port is accepted). After a valid frame is received from one of the interfaces, the corresponding command is executed and a reply is sent back to the host. Below is a short description of the “command” and “response” frame format. Host to reader frame (command): <SOF> <Address> <Command ID> <Nb Data> <Data> <Checksum> Reader to host frame (response): <SOF> <Address> <Error Code> <Nb Data> <Data> <Checksum> Field Description <SOF> Start Of Frame (01h) <Address> When RS422 or RS485 communication modes are supported, only the reader whose StxNG address matches this field executes the command and replies. This field is ignored by Medio L400. <Command ID> In a command frame, the ID of the command that should be executed. Command IDs are in the range 0000h-7FFFh <Error Code> In a response frame, the error code if an error occurred during execution. Error codes are in the range 8000h-FFFFh. If no error occurred, the command ID is repeated. <Nb Data> The Data field length in number of bytes. <Data> In a command frame, the parameters for the command. In a response frame, the return values associated to the command. <Checksum> A checksum. This is the arithmetic sum off all previous bytes. The reader is never allowed to send data over its interfaces without having received a command from the host. For more information about StxNG protocol and a complete command set description, please refer to Medio L400 Designer’s guide. 5.2.2 Heartbeat The heartbeat service applies to the 10/100 Ethernet interface only. When activated, the heartbeat service periodically broadcasts Ethernet packets containing product name, description, location, IP A simple password-based security mechanism can be activated to prevent unauthorized access to the reader. In such a case, the host system must first execute a specific command to identify itself before being allowed to send any other command.
Advanced Notions March 2008 Revision 1.6 39/51 address and TCP ports on which reader is listening for incoming connections (see StxNG protocol). This heartbeat is useful to: • Show Medio L400 readers connected to the same physical network as the host. • Check that a Medio L400 reader is operating properly (in this case, the heartbeat acts as a watchdog). For more information about heartbeat please refer to Medio L400 Designer’s guide. 5.2.3 Telnet The telnet server applies to 10/100 Ethernet interface only. A host can connect to the reader using any standard telnet client. The Telnet server makes it possible to configure the microsystem only (serial port configuration, TCP/IP stack configuration, date/time configuration, version query…). For more information about telnet server please refer to Medio L400 Designer’s guide. 5.2.4 Serial console The serial console applies to RS-232 and USB interfaces only. A host can connect to the reader using any standard terminal application. The serial console makes it possible to configure the microsystem only (serial port configuration, TCP/IP stack configuration, date/time configuration, version query…). The reader automatically detects if current data exchanges over its serial and USB ports are StxNG protocol frames or console frames and reacts accordingly. Consequently, there’s no need to configure those interfaces for console or StxNG protocol operation: both are simultaneously available. For more information about serial console please refer to Medio L400 Designer’s guide. RFID configuration and control (for example activating a channel and reading a tag) is not allowed with telnet server. A simple password-based security mechanism can be activated to prevent unauthorized access to the reader. RFID configuration and control (for example activating a channel and reading a tag) is not allowed with serial console. A simple password-based security mechanism can be activated to prevent unauthorized access to the reader.
Medio L400 40/51 Revision 1.6 March 2008 5.2.5 Standalone mode Standalone mode makes it possible to use the reader without the need for a host to control it. In this case, only the tag reading operation is available. When standalone mode is activated, the reader automatically loads its last saved configuration upon start-up and initiates a read session. Each time a read event occurs, the reader sends a frame over its serial port. Frame format is as the following (all fields are ASCII, optional and customizable): <Header><Timestamp><Radio ID><Event Type><Channel><Tag Type><Tag Data><Footer> A watchdog can also be activated. In this case, a customizable frame is sent periodically over the serial port to indicate the reader is operating properly. For more information about standalone mode operation and configuration, please refer to Medio L400 Designer’s guide. 5.3 Reader operation principles Most of the reader commands are executed in a synchronous manner. This means that the reader waits for an incoming request from the host, executes the associated operation then sends a reply containing operation execution status back to the host. Between the reception of two consecutive commands, the reader does nothing but wait for the next command. The following commands are examples of commands executed in a synchronous manner : • Configuration commands (configuring the TCP/IP stack, for example). • Tag writing commands (writing an ISO15693 tag memory block, for example). • Most tag reading commands (reading the locking status of an ISO15693 tag memory block, for example). Synchronous commands that actually perform an operation on tags in the RF field (such as a writing operation, opposed to a configuration command) can only use a single channel (multiplexer can not be used). The channel and RF power that should be used for any subsequent synchronous tag operation is called the default RF configuration (specific commands exist to get/set this configuration). An exception to the mechanism described above exists: the asynchronous read (or default read). Asynchronous read (or default read) can be activated or deactivated using the appropriate commands in the command set. During asynchronous read, the reader continuously tries to read all tags in the field. When a tag is detected, one or several read events are asynchronously pushed into an internal buffer (the event buffer). The host system then needs to poll the event buffer periodically to retrieve the latest events. One can specify the kind of read events that should be reported during asynchronous read, as well as several options (called read modes) that should be applied during asynchronous read. The following sections provide more details about the different read events, as well as the different read modes. 5.3.1 Notion of read modes During asynchronous read (or default read), the reader continuously tries to read all tags in the RF field. Several options can be applied that modify the reader’s behavior during asynchronous read: • “Multiplexer” : If this mode is active, the reader uses the multiplexer instead of the default RF configuration for reading. The multiplexer makes it possible to define a sequence of
Advanced Notions March 2008 Revision 1.6 41/51 antennas, tag types and RF output powers that will be automatically used during the reading process. For example, a user can configure the multiplexer so that reader tries to read ISO15693 tags for 100ms on channel 1 at 1Watt, then ICode UID tags for 50ms on channel 1 at 2Watts, then ISO15693 tags for 100ms on channel 2 at 1Watt, then ICode UID tags for 50ms on channel 2 at 2Watts. • “Input triggered” : If this mode is active, the reader waits for GPIO Input #1 to become active in order to activate the RF field and start reading. When GPIO Input #1 gets back to inactive state, RF field is turned off and the reader stops reading until input is active again. Active input level (low or high) is software configurable. • “Output feedback” : If this mode is active, the reader uses GPIO Outputs #1, #2 and #3 to signal reading activity. GPIO Output #1 is activated when the reader is attempting to read tags, GPIO Output #2 is activated when the reader “sees” tags in the RF field. In input triggered read mode GPIO Output #3 is activated when the trigger condition ends and no tag was detected in the RF field. When Input triggered read mode is inactive, GPIO Output #3 remains inactive. The time an output remains active after the corresponding event has occurred is software configurable. A user can activate one or several read modes at once, depending on the application requirements. 5.3.2 Notion of events During asynchronous read (or default read), the reader continuously tries to read all tags in the RF field. When a tag is detected, one or several events are pushed into an internal event buffer. Those events contain information such as the kind of event (see below), a timestamp, the channel on which the event occurred, the tag type and the associated tag data (UID, memory…). The following events are supported : • “Tag Read” : This event is pushed each time a valid tag frame is decoded, without further processing. When activated, this event may be triggered several hundreds of times per second and is consequently bandwidth consuming. It is often used for testing purpose only. • “Tag New” : This event is pushed each time a new tag is detected. If the same tag is detected several times, it will be reported only once. • “Tag In” : This event is pushed each time a tag enters the RF field. • “Tag Out” : This event is pushed each time a tag leaves the RF field. • “Tag No Read” : When Input triggered read mode is active, this event is pushed when the trigger condition ends and no tag was detected in the RF field. When Input triggered read mode is inactive, this event is never pushed. A user can register for one or several events at once, depending on the application requirements. For example, if a user registers for all events and a tag enters the RF field, stays in the field for some time, then leaves the field, the sequence of events pushed into the event buffer will be: • “Tag Read” • “Tag New” • “Tag In”
Medio L400 42/51 Revision 1.6 March 2008 • “Tag Read” (repeated as long as the tag remains in the field) • “Tag Out” If the same tag re-enters the RF field at a later time, stays in the field for a period of time, then leaves the field, the sequence of events pushed into the event buffer will be : • “Tag Read” • “Tag In” • “Tag Read” (repeated as long as the tag remains in the field) • “Tag Out”

The remedy provided above is in lieu and to the exclusion of all other remedies, obligations or liabilities on the part of TAGSYS for damages, whether in contract, tort or otherwise, and including but not limited to, damages for any defects in the Products or for any injury, damage, or loss resulting from such defects or from any work done in connection therewith or for consequential loss, whether based upon lost goodwill, lost resale profits, impairment of other goods or arising from claims by third parties or otherwise. TAGSYS disclaims any explicit warranty not provided herein and any implied warranty, guaranty or representation as to performance, quality and absence of hidden defects, and any remedy for breach of contract, which but for this provision, might arise by implication, operation of law, custom of trade or course of dealing, including implied warranties of merchantability and fitness for a particular purpose. 7.2.2 How to Return Defective Products The Buyer shall notify TAGSYS of the defects within 15 working days after the defects are discovered. Defective Products must be returned to TAGSYS after assignment by a TAGSYS Quality Department representative of an RMA (Return Material Authorization) number. No Products shall be returned without their proof of purchase and without the acceptance number relating to the return procedure. All Products shall be returned with a report from the Buyer stating the complete details of the alleged defect. Call +33 4 91 27 57 36 for return authorization and shipping address. If returned Products prove to be non-defective, a charge will be applied to cover TAGSYS’ analysis cost and shipping costs. If the warranty does not apply for returned Products (due to age, or application of a warranty exclusion clause), a quote for replacement will be issued, and no replacement will be granted until a valid purchase order is received. If no purchase order is received within 30 days after the date of TAGSYS quote, TAGSYS will return the products and charge the analysis cost and shipping costs. All replaced Products shall become the property of TAGSYS. The Product Return Form is included on the following page. This form should accompany any product you need to return to TAGSYS for analysis in the event of a problem.
