Chapter 1 Introduction T he S556-EP InstaScan scanners and Dura-label Radio Frequency (RF) Identification Tags developed by SCS are state-of-the-art data gathering and inspection systems that combine sophisticated Interactive Identification technology in a compact form factor. This unique synergy allows our system to integrate seamlessly into — and significantly increase productivity for — a wide range of applications and environments.
Advantages Data-gathering systems such as bar code readers use one-way communication: a sensor reads information from a device, without any interaction between the two devices. Moreover, bar code systems are subject to line-of-sight limitations. As a result, airborne contaminants such as dust, dirt, oil, and mist, as well as label damage and objects residing outside the line of sight, result in inefficient and erroneous results.
This unique capability allows: • Collective or selective data to be read from a single tag. • Collective or selective data to be read from multiple tags without requiring sorting or unpacking. • Classes of tags to be filtered according to user-defined criteria. This technology employs a superior interrogation feature that enables applications to uniquely identify all tags in the scan field, without misidentification or identifying the same tags multiple times.
S556-EP InstaScan Scanner The S556-EP scanner is designed for applications or configurations that require the scanner to be a considerable distance from tags, or where numerous tags are required to be read simultaneously. Conveyor belt applications are ideally suited to the scanner. The scanner provides six pairs of coaxial connectors for supporting up to six external antennas. Each antenna plugs into its own set of connectors on the front panel of the scanner. Figure 2.
What Else You Need To complete your system, you need an IBM or compatible personal computer with the following minimum system requirements: • 486 processor or better • Compatible screen and keyboard • 9-pin RS-232 port • Windows 95 or 98 • 16 MB of RAM (32+ MB recommended) • FCC Part 90 Site License (U.S. Customers) The applications you use to interface with this system may have additional hardware and software requirements.

Placing the Antenna Antenna placement is critical to ensuring that information is transmitted to and from tags accurately. Observe the following guidelines when placing the antenna: Locate the antenna away from metal objects, microwave ovens, and other devices that may induce radio frequency interference. In addition, make sure there are no metallic surfaces between, or in relative proximity to, the scanner and tag. For additional placement considerations, refer to “RF Communications” on page 23.
Connecting to a PC Serial Port or RS-232 The scanner has a 9-pin female RS-232 connector that connects to a serial port or RS-232 connector on an IBM or compatible personal computer. The serial port can operate up to 57,600 bps. To make this connection, you need: An appropriately configured serial cable. One of the following adapters, if your computer’s serial port does not have a 9-pin connector: - A 15-pin to 9-pin adapter, if your computer has a 15-pin serial port connector.
Connecting to an AC Outlet The following procedure describes how to connect the scanner to an AC Outlet. 1. Verify that the On/Off switch on the scanner front panel is in the OFF position (see Figure 3). 2. Connect the power cord to the AC receptacle in the scanner front panel (see Figure 3). 3. Connect the other end of the power cord to the wall outlet. 4. Set the On/Off switch to the ON position. The Power ON LED lights. 14 556-EP Manual.
Configuring the Scanner The following procedure will verify that the RS-232 link between the scanner and the computer is working correctly. 1. Insert the supplied Series 5 Development and Demo Tools, Disk 1, into an available floppy disk drive. 2. Open the “My Computer” icon on the desktop. 3. Open the floppy disk drive (typically A:). 4. Run the application “Setup.exe” 5. Installshield will launch and guide you through the installation of the Series 5 Tools onto your computer. 6.
10. Look for the text “Scanner type = XXXX” in the application dialog. If “XXXX” is not “S556-EP”, select “S556-EP” from the Scanner menu of the Series 5 Test Tool application. 11. Look for the text “Mode = ...” in the application dialog. If the mode is not “Basic Function Test”, select “Basic Function Test” from the Mode menu of the Series 5 Test Tool application. 12. There are three tests you must run in order to confirm that the scanner is working correctly.
17. Each List Test is composed of three commands given to the scanner. If the test is successful, all these tests should say “OK” after the test name. The application will ask you to repeat the List Test with 1) A single tag, and 2) two tags in front of the antenna. The test is complete when the application successfully detects two tags. 18. The Write Test requires a write - capable tag. Position the object with the tag within 22 inches of the antenna. 19.
Aligning the Antenna After verifying that the scanner is operating properly, use the following procedure to align the antenna(s). Aligning the antenna(s) ensures optimal performance. 1. Connect the scanner to COM1 or COM2 and turn the power on. 2. Run the application “Series 5 Test Tool” in the “Series 5 Tools” folder in the start menu. 3. From the mode menu, choose “Antenna Alignment”. 4. Select the antenna you wish to align with the available antenna buttons. Press the “Go” button. 5.
Installing Dura-labels Dura-label RF tags have a diminutive form factor that allows them to be installed in areas that cannot accommodate conventional RF tags. In addition, Dura-labels can communicate with the scanner without having to be in the line-of-sight. This unique combination provides tremendous flexibility when determining a location for placing tags.
Reading Information from your Dura-labels Once you have installed your tags, and have set-up your scanner system, you are ready to begin. 1. Run the “Series 5 Demo” application in the “Series 5 Tools” folder in the start menu. 2. The connect dialog box will appear, set COM Port to the port where the scanner is connected, Baud Rate to the highest value supported by your computer and cable length. Set “# of Antenna” to the appropriate value then click the “Connect” button. 3.
Writing Information to Your Dura-label Read/write tags can be written to using the scanner. Each bit of memory is write once, read many (WORM). Meaning after you have written to a specific bit, it is permanent and cannot be overwritten or erased. To add more data to the tag you must write to a different bit. Another feature included with each user-writable word of memory is a Write-Protect bit. This bit allows you to protect an entire word (16 bits) after any or all of the bits have been written. 1.
7. To write to a block of memory locations, use the commands in the block section of the window. Enter the starting memory location in the “From” window. Enter number of memory locations in the “Length” window. The ending memory location will be automatically calculated in the “To:” window. Click the box to the left of the “Write” text and enter the data in the window below the “Write” command. 8. To write protect the entire block, click the box to the left of the “Write Protect” text. 9.
Chapter 3 RF Communications I n general, devices that communicate using radio frequency, such as your system , can be sensitive to signal interference and signal attenuation. This chapter provides tips for optimizing radiofrequency (RF) communications with your InstaScan and Dura-label. Topics in this chapter include: • Signal interference — see page 24 • Signal attenuation/reflections — see page 25 • Optimizing performance — see page 26 23 556-EP Manual.
Signal Interference Signal interference is RF signals that interfere with the information being exchanged between the tag and scanner. Signal interference can severely diminish the scanner’s ability to read information from the tags. The Activity LED on the scanner flickers constantly if it detects signal interference. The source of the interfering signals may be: • An RF system, such as an RF local-area network (LAN) or another Interactive Identification system, located close to your system.
Signal Attenuation/Reflections Signal attenuation is the loss of signal strength that occurs naturally over distances, but which can also be caused by RF barriers in the signal path. Examples of such barriers include: • Enclosed locations that have concrete walls, floors, and ceilings. • Metal surfaces surrounding the antenna or tag. • Water or other fluids surrounding the antenna or tag. Almost every object (furniture, partitions, and people) in the path of a signal causes some degree of attenuation.
Optimizing Performance While it is not possible to predict how the system will perform in any given environment, observing the following guidelines will help optimize performance in your environments and applications: Carefully plan the placement of the scanner antenna. The antennas can be extended extended approximately ten feet from the scanner depending on cable length purchased for the application.
