BEFORE YOU BEGIN Introduction to T201 The Ekahau T201 Wi-Fi tag is part of Ekahau RTLS (Real-Time Location System) that consists of the award-winning Ekahau T201 tags and Positioning Engine (EPE) software platform, enabling realtime people and asset tracking in any standard Wi-Fi network. The T201 tags can be attached to any mobile object or asset, and can be carried by people as well.
PAGE 4
The T201 splash proof enclosure has a power / call button, two status LEDs, buzzer and a configuration /charging port.

Any sequence. parameters. System Requirements 1. Laptop or Tablet PC with at least Windows® XP or 2000, 1 GHz processor, 256 MB RAM, and 200 MB of disk space. 2.
PAGE 6
NOTE For quick evaluation and development setup, install all EPE components on the laptop PC and refer to the EPE User Guide on creating a Positioning Model using the Ekahau Manager. Test the Positioning Model by walking around the site with the laptop while observing your location on the map. Then save the model in the Positioning Engine. Charging T201 Tags T201 internal battery needs to be charged before use. 1. Apply the charger provided by Ekahau.
PAGE 7
3. Open any terminal program, such as Windows HyperTerminal. Click Start > Programs > Accessories > Communications > HyperTerminal. Creating a New Connection with HyperTerminal on Windows® XP. 4. Name a New Connection, such as “T201”, and connect using a COM port, such as COM1. If you cannot access the tag’s CLI, try another COM port number until you find the correct port. 5. Select the communication parameters.
PAGE 8
The correct COM port settings. If you cannot access the CLI, try a different COM port number, such as COM2 or COM3. 6. Switch on the tag by keeping the call / on-off button pressed down for 5 seconds. Release when green status LED appears. It may take up to 10 seconds until the tag displays its CLI prompt. If the battery is too low or empty, you will get red status LED or no light at all. Then plug the power cable in and try again.
PAGE 9
The CLI prompt displays the Ekahau tag software version and serial number (or friendly name). Using the Configuration Interface Execute CLI commands with the Enter key. When you execute CLI commands, they are activated immediately without asking for confirmation. List all configuration parameters by typing config. Save the configuration changes to permanent memory by typing save. Any unsaved changes will be lost during the next tag sleep or power-off period. The command line is editable.
PAGE 10
Setting Parameter Value Parameter values are set by typing the full parameter string and its value to the command line. E.g. setting the associated network’s name (SSID) to “test-wlan” and saving it to tag’s permanent memory: tag[00001]# wlan ssid ”test-wlan” tag[00001](unsaved)# save Any unsaved changes will be lost during the next tag sleep or poweroff period. Successful execution gives no feedback to the user.
PAGE 11
Minimum Configuration To allow T201 associate with your Wi-Fi network and communicate with the Positioning Engine, you must configure at least: SSID (network name is always required) Positioning Engine IP address (always required) WEP key as a string or hex bytes (if WEP is enabled) T201 IP address or method (if DHCP service is not available)) T201 friendly name (optional but recommended) It is recommended to name each T201.
PAGE 12
Configuring Multiple Tags To configure tags faster, it is helpful to create a text file that contains the preferred configuration settings, and send the file to the CLI with any terminal program. 1. Open Windows Notepad or similar plain text tool, and write a configuration parameter on each row. For example: wlan ssid test-net engine ip 192.168.1.1 wlan wep 1 26:4d:29:42:34:28:4d:69:44:30:24:4d:29 save 2. Save the file for example as T201_settings.txt. 3.
PAGE 13
Communication Parameters These parameters are required to let the tag associate with the Wi-Fi network and communicate with the Positioning Engine. You must configure at least the SSID, the tag’s IP address (automatic DHCP or manual configuration), and Positioning Engine’s IP address. WLAN Parameter Syntax Factory Min Max Type WLAN SSID wlan ssid 1 “SSID” OR Ekahau 1 4 R/W index off 0 0 1 R/W 1 4 R/W Configures up to 4 SSIDs Tag attempts to use SSIDs from index 1 to 4.

T201 gives mistaken status "Associated" even if the WEP key is not correct. This is because WLAN driver gives correct response that it has "associated" to access point, but it does not inform if "Authentication" was successful. To avoid problems with the authentication make sure that the WEP key(s) are set correctly. T201 supports roaming between different SSIDs. This is implemented by scanning all audible networks and selecting the SSID in index 1. If that is not audible then index 2 and so on.

FCC RF Radiation Exposure Statement This equipment complies with FCC Radio Frequency Electromagnetic Signal (RF) exposure limits set forth for an uncontrolled environment of portable transmission. This product has been evaluated for RF exposure at a distance of 0,5 cm (0,2 inches). Operation at a separation distance less than 0,5 cm (0,2 inches) from the radiating element to nearby persons will expose nearby persons to RF levels that exceed the FCC rules for RF exposure.
PAGE 29
Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the tag. Do not paint the tag. Paint can clog the moving parts and prevent proper operation. Use a soft, clean and dry cloth to clean the tag. Use only the supplied antenna. Unauthorized antennas, modifications or attachments could damage the tag and may violate regulations governing radio devices. All of the above suggestions apply equally to your tag, battery, charger or any accessory.
