SR100 User Guide Page | 6 CHAPTER 1 SR100 OVERVIEW The SR100 is RFID portal reader with an integrated antenna designed for use in North America and Europe. The SR100 can read and write to ISO 18000-6C (EPC Class 1 Gen 2) transponders with a maximum output power of 1W. FEATURES • Common communications protocol – All SkyeTek products use SkyeTek Protocol v3 (STPv3) to drive low level communication. SkyeTek’s C and C# APIs are built on top of this protocol to give users methods for all reader and tag operations to use from custom software applications. • The SR100 has an internal 5dBi Circular Polarized antenna as well as a 50Ohm output to connect and external antenna. • Communicate via USB or TCP over Ethernet. Send STPv3 commands to the reader using these two interfaces allow easy integration into most modern systems. Users can access all reader functions over both interfaces, including firmware upgrades, security features and all tag commands. SKYEREADER CONSOLE The SR100 ships with the SkyeReader Console software package. This software runs on Windows XP, Vista, and 7.

SR100 User Guide Page | 11 CHAPTER 5 RADIO SPECIFICATIONS AND REGIONAL COMPLIANCE RF RADIO POWER The output power of the SR100 is adjustable from 10-30dBm in steps of 0.1dBm with +/- 1dB accuracy. With this adjustable power, the user can configure the device to suit their needs of reading transponders at different ranges, or to reduce overall power consumption. See “Power Level” on page 22 for information on how to set the RF output power. FREQUENCY RANGE The SR100 is a multi-frequency device that can operate anywhere in the 860-960MHz range, which covers the world’s major UHF RFID bands. The user can set a Start and Stop frequency so the reader may operate in a subset of this band. See “System Parameters” below for more information on adjusting the Current, Start and Stop frequency for the reader. SkyeTek will lock all pertinent system parameters for a given region (frequency, hope channel spacing, etc.) when the unit is sold in said region. This is to prevent the user from violated regional regulations. TAG PROTOCOLS The SR100 supports basic tag commands (identify, read and write) for the following tag protocols: • EPC C1G2 (ISO 18000-6C) • iPX EM NOTE - For additional tag support information, see the Tag Support list included with the documentation for your SR100. REGIONAL REGULATIONS The SR100 has been tested and approved for regional compliance in the following regions. Region Agency Approvals Publications/Regulations North America FCC Part 15 Europe ETSI RADIO SPECIFICATIONS For the table below, assume an operating temperature of 25°C.

SR100 User Guide Page | 13 CHAPTER 6 HOST INTERFACE SPECIFICATION This chapter describes the host interface connections of the SR100. The SR100 supports two host interfaces: • USB • TCP/IP over Ethernet Each interface is active when the user makes the connection with either an Ethernet cable or a USB cable. If both cables are connected, USB has priority and the Ethernet connection will not be able to communicate with the reader. The SR100 receives and transmits STPv3 commands over both interfaces. USB The SR100 supports a USB Full Speed connection. It uses a USB to serial converter internally to communicate with the reader which requires a driver to be installed on your host computer. This driver is included with the software CD, is installed automatically with the SkyeReader Console software, or can be downloaded from www.ftdichip.com/Drivers/VCP.htm. TCP/IP The SR100 can use TCP sockets for communication as well. The C# API provides methods for device discovery and communication, but if you want to use a different programming environment, the information below describes how these methods work. DISCOVERY The SR100 utilizes the .NET Micro Framework for network communication. This is very nice because a discovery function is built into the device. All that is required is to send the string “DOTNETMF” over a UDP Multicast on your network. The device will receive this string and send out a UDP Multicast that looks like this: You can use the MAC Address and IP Address from this response to create a socket connection as described below. You can match the MAC Address from this response to the one printed on the label on the bottom of your SR100.
SR100 User Guide Page | 14 The SR100 uses DHCP to dynamically obtain an IP address. When you first apply power to the unit and then a network connection, it will take a few seconds for this process to complete. You can watch the LEDs on the Ethernet connector for an indicator; when the Green LED starts blinking, the device is communicating with the network and you may try the discovery process. OPENING A SOCKET After you have discovered your device’s IP Address, you can now open a TCP socket to your SR100. The SR100 is always listening for a new connection if it is not already connected. You must use the following parameters: • Two way communication socket (stream) • Use Port 2000 After the socket connection is established, you may stream data across this socket freely. The SR100 will receive and transmit STPv3 commands and responses. To close the socket, simply terminate the connection, and the SR100 will recognize the connection has been closed and listen for a new one.
SR100 User Guide Page | 15 CHAPTER 7 ANTENNA OPTIONS The SR100 supports two antenna options: internal antenna and external antenna. The default is to use the internal antenna because it is always connected. To change the active antenna, the user sends a Write System Parameter command to the reader with the following attributes: Command Address Blocks Data Write System Parameter 0x0060 0001 0x01 for external 0x02 for internal (Default) You can also issue a Store Default System Parameter with the same attributes to keep your settings after a power cycle. INTERNAL ANTENNA The internal antenna is a 5dBi gain Circularly Polarized patch antenna. This high performance antenna will allow the user to read tags up to 5m from the reader in free space. Because it is circularly polarized, tag orientation does not play a major factor in read distance. EXTERNAL ANTENNA The SR100 can use any external antenna with a 50Ω load. Keep the following items in mind when selecting an external antenna: • Antenna Gain – The SR100 has 1W of output power, and the maximum EIRP allowed by the FCC is 4W. The highest gain antenna that can be used with the SR100 in North America is 5.35dBi. Check regional regulations for other restrictions. o Antenna gain is also directly related to beam width. The higher the gain, the more directional the antenna is, and the narrower the beam width. • Cable – Different cables have different losses over distance. For example, standard RG58 coaxial cable losses approximately 0.49dB/meter. Over longer distances, this can cause significant loss of power. • Polarization – A linearly polarized antenna will be very sensitive to tag orientation, where a circularly polarized antenna will not be as sensitive.
SR100 User Guide Page | 16 CHAPTER 8 SOFTWARE SPECIFICATIONS HOST COMMUNICATION – SKYETEK PROTOCOL V3 The SR100 uses SkyeTek Protocol v3 for all communication.
