The SkyeModule itself does not operate without direction (commands) from a host. The host can be in the form of a PC or, more typically, an embedded microcontroller. This document explains the physical and electrical characteristics of the module, so you can understand how to integrate the Nova into a finished product. For initial demonstration of the module, SkyeWare v4 software is available on the media that came with the developer/evaluation kit or available for download at support.skyetek.com. Open this software on your windows PC and it will be recognized when you connect through USB or RS232 (with developer kit interface board). The software demonstrates features like selecting tags, reading and writing. It also has a powerful command builder that lets you format, send and receive any command to and from the reader. More about SkyeWare can be found in the SkyeWare User Guide. See the Additional Reading section below. The next step after demonstrating the module’s functionality is developing your own communication with the module. This can be achieved with simple code on a microcontroller or using the SkyeTek API on a PC. Once connected to a host through one of the four host interfaces, the reader to host communication is formatted with a full featured protocol called SkyeTek Protocol v3. In order to make learning commands and formatting easy, we have developed a series of application notes with examples to get you started. The application notes start with basic tag and reader commands and become very detailed for tags with special features. Read more about the protocol and commands in section 12, Communicating with the Module and then move on to the Additional Reading in section 1.3. 1.2 Why a SkyeTek Module? Many customers may wonder, “What value does a module add over an RFID transceiver chip?” RFID transceiver chips may seem simple, but they actually require significant engineering time and capital investment to integrate. Transceiver chips contain up to 50 registers for configuration and functionality. In addition, communicating over air protocols such as ISO18000-6C is complex, described in nearly 150 pages of cryptic procedures. For example, just selecting a tag requires a minimum of 6 and up to 100 over air interactions with multiple tags present. SkyeTek has also optimized the complex RF chain to give the best performance and efficiency possible. SkyeTek modules mask the complexities of RFID from the user and pack functionality into just a few commands. SkyeTek’s core set of commands allow the user to read and write to tags with a single command, regardless of the tag type. The module is also field upgradable, so you can use the latest security algorithms and tag features as they are released. Power regulation and filtering for the radio are handled in the Nova, so you can supply voltage directly from an unregulated source like a battery. Finally, the Nova will be modularly approved by the FCC and CE, so you can bypass expensive radio testing at a certified test lab and avoid potential schedule delays due to failures. Using a SkyeTek module will greatly reduce time to market and upfront development costs. Allow SkyeTek to take the burden of developing an RF system so you can focus your energy on your core products.

Lorsqu'il est intégré au sein de produit final, des tests supplémentaires de radiateur involontaire peut être nécessaire. 9.4 EU Guidelines The SkyeModule Nova was tested to the standards defined by ETSI 302 208-1 (Electromagnetic compatibility and Radio spectrum Matters; Radio Frequency Identification Equipment operating in the band 865 MHz to 868 MHz with power levels up to 2 W). In order to market and sell product in the European markets, manufacturers need to demonstrate compliance using a Declaration of Conformity. Unlike the United States, there is no certification process through a regulating body. Instead, manufacturers have the sole responsibility of ensuring their products are compliant to the applicable directives and standards. Also, unlike the USA and Canada, there are no “Modular Approval” rules under the ETSI standards, and the integrator must either declare conformity of the entire system based on the testing of the module, or perform additional testing with the complete integrated system including antenna(s). Since conducted testing was performed with the module, it is straightforward to show compliance with a particular antenna based on its radiation characteristics. Upon request, Skyetek will provide ETSI test data and reports as necessary to aid in showing compliance to the ETSI standards when the Nova is integrated within the final product. Skyetek can also provide it’s Declaration of Conformity (DoC), if requested. In addition, Skyetek engineers are available to assist in EU compliance matters. 10 Host Interface Specifications The SkyeModule Nova supports the following microcontroller host interfaces for easy integration into existing systems:  USB (Overrides other interfaces when connected)  TTL Serial  SPI  I2C The SkyeModule Nova and the host interface board support TTL Serial and USB communications. The host interface board provides a USB connector and a TTL to RS-232 level converter for the TTL Serial host interface. The Host Interface system parameter determines which host interface is used for communication with the host. Each interface is software selectable and only one host interface is active at a time, however, USB may always be connected and overrides the current interface. The host interface is selected based on the

The SkyeModule Nova operates under host control using SkyeTek Protocol v3 sent over one of the host interfaces described in this chapter. The following sections describe the power and host communication connections for the SkyeModule Nova. The SkyeTek Protocol and commands are described further in section 12, Communicating with the Module.

The SkyeModule Nova uses a standard HID driver but is not a certified USB device. The SkyeModule Nova supports both standard and high speed USB hosts and enumerates correctly on both Windows and UNIX platforms. The USB interface is typically only used for demonstration as a USB host controller is not usually available in embedded systems. To communicate with the reader in USB mode, either SkyeTek (Skyeware) demonstration software or the SkyeTek APIs can be used. See the SkyeTek support site for the latest software and API downloads at support.skyetek.com. Figure 10-1 shows an example of a circuit to permit USB communications without using the host interface board. Figure 10-1: USB Connection Diagram NOTE – If powered by USB, the USB host must be capable of supplying the USB standard high power device, 500mA at 5V. Also, the Nova will always communicate via USB, when a USB host is connected.

Data exchange between the host and the SkyeModule Nova occurs according to SkyeTek Protocol v3 (ASCII or Binary mode). See more about the protocol in section 12, Communicating with the Module. Serial communication is the most common and robust host interface for this module in an embedded system. Because the interface is asynchronous, the module responds immediately upon command completion instead of waiting for a host clock as in SPI or I 2C. Figure 10-2 shows a sample circuit that lets you connect the SkyeModule Nova without the host interface board. This circuit uses an RS232 to TTL level converter to allow connection to a PC serial port. For direct connection to a micro serial interface (using TTL/CMOS levels), simply connect directly to pins 49 and 51 of the Mini PCI express connector. Figure 10-3 shows examples of typical communication on a signal level. [PICTURE] Figure 10-2: Serial Connection Diagram

There is also an optional data ready signal to indicate that the current command is complete and data is available for the host. Figure 10-4 shows an example of a host interface connection using SPI. Power and ground lines are omitted from this drawing for simplicity. Please refer to Figure 10-1 for power and ground connection details. Figure 10-4: SPI Simplified Connection Diagram The protocol for requests to the SkyeModule Nova is outlined below:  The data packet exchange between the host (SPI Master) and the Nova (SPI Slave) uses SkyeTek Protocol v3 (Binary Mode only). See more about the protocol in section 12, Communicating with the Module.  The host must implement SPI master functionality.  The SCK line is the master clock controlled by the host and should remain low during idle state.  The slave select line is active low.  The data is setup on the rising edge of SCK.  The message data is latched on the falling edge of SCK.  The MOSI signal line provides the data from the host to the SkyeModule Nova.  Supports data rates up to 4 MBit  Both 3.3V and 5V logic levels are allowed.

The module will respond with 0x00 when no data is present, and 0x02 (start of frame) when data is available.  Response data will be thrown away if not read within 10 seconds of becoming available.  The MISO signal provides the response data from SkyeModule Nova to the host.  To retrieve data on the MISO line, the SSEL (Slave Select) signal must be low when the clock is sent for an entire byte. Between bytes, SSEL can either stay low or transition high again as long as it transitions low before the first clock of the next byte.  The host can use the data length field (response bytes 2 and 3) in order to determine how many bytes to read from the module as these first bytes will always be present immediately following a start of frame (0x02). Figure 10-7 below shows the timing required to retrieve data on the MISO line. CLKMISOSSELResponseGPIO3_DR Figure 10-7: SPI Response Timing NOTE – Not reading the entire response before sending another command can cause undesired behavior. Always make sure to read the entire response when using the SPI interface.

The ports use an Ultra Miniature Connector (U.FL) to save space and cost. Any 50 ohm antenna in the appropriate frequency band (865-868MHz for Europe, 920-928MHz for North America) can be used with the Nova, however to maintain compliance with FCC/IC regulations, we recommend using those (or similar type) antennas specified in section 9 of this document in the USA and Canada. The SkyeModule Nova also uses an advanced Adaptive Antenna Tuning circuit to ensure a quality impedance match with any antenna. The user can take advantage of this feature by first attaching the antenna to the port they would like to use, then sending a SkyeTek Protocol command to the Nova for it to execute its tuning sequence. The Nova will measure the reflected power caused by impedance mismatch and then will automatically compensate, delivering the maximum power to the antenna while reducing noise in the system. NOTE – Read range depends on antenna choice and operating environment. Range can vary widely, depending on your choice of tag inlay and antenna gain.

Research, record, and test all planned changes to make sure they are compatible with your system. You can read or write system parameters via the following commands:  Read System Parameter – Reads the current value of the system parameter at the memory address specified.  Write System Parameter – Writes a new value to the system parameter at the memory address specified.  Store Default System Parameter – Writes a new system parameter value to the non-volatile memory. This saves the setting even after a power cycle or reset.  Retrieve Default System Parameter – Reads the system parameter value at the address specified out of non-volatile memory. See System Parameter Detail in section 13.3 for detailed information about individual parameters. For full examples of how to use these commands, see the system parameter examples found in the Using SkyeProtocol V3 Reader Commands application note. CAUTION – Resetting (cycling power) on your SkyeModule Nova causes all system parameters to revert to their default values. Any changes made to system parameters in memory are lost at reset unless you write them to the non-volatile memory as the new default values. Any changes to the default values do not take effect until the reader is reset. 13.3 System Parameter Details This section describes the SkyeModule Nova system parameters. 13.3.1 Serial Number  Returns the serial number of the reader  Parameter address: 0x0000  Length (bytes): 4  Default value: 0x00000000  Read-only 13.3.2 Firmware Version  Returns the firmware version currently loaded on the reader.

The deep sleep mode has the lowest power consumption but a longer wake time. It can only be set using the N_DEEP_SLEEP pin 20 of the host interface connector. There is an internal pull-up on this pin, so if it is unused it can be left floating. To put the reader into deep sleep, set this pin low. Software sleep mode can be set using the Operating Mode system parameter. See the System Parameters section 13 for details. Current consumption and wake times for both modes can be found in the Error! Reference source not found. section Error! Reference source not found. and Error! Reference source not found. section Error! Reference source not found., respectively. NOTE: SOFTWARE SLEEP MODE DOES NOT WORK IN USB COMMUNICATIONS. This is planned for future firmware releases. 14.2 Feature Requests Request a feature for the Nova module on the SkyeTek support page at support.skyetek.com!
