SkyeModule Gemini Datasheet

1.1
Operating your SkyeModule Gemini begins with finding a method to connect to a host. 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 Gemini 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 Protovol 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 13, Communicating with the Module and then move on to the Additional Reading in section 1.3.

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 ISO14443 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 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 Gemini handles complex cryptography, which many modules lack, to
easily add more security for access control or payment systems. 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 Gemini, so you can supply voltage directly from an unregulated
