Application defined A sequence defined and activated by configuration parameters. Any sequence. 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. The laptop must provide a standard 9-pin serial connector for the tag’s configuration cable. If your laptop has USB connectors only, purchase an external USB–serial cable (9-pin) adapter. 3. Ekahau splitter cable for connecting the tag to the serial cable and to a power adapter. 4. Supported Wi-Fi adapter (see http://www.ekahau.com/devices or Ekahau Client Release Notes) to create a Positioning Model. Communication with the tags can be facilitated via the Wi-Fi adapter, or Ethernet cable, provided that your Ethernet network is connected to your Wi-Fi network. 5. The Ekahau Positioning Engine (EPE) software, license keys, and license files, fully installed on the laptop PC. 6. At least 3 operational Wi-Fi access points (802.11b/g). 7. Map image of the facility or area (JPG or PNG). You can draw a map image yourself with any drawing tool, if necessary.
7 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. If you want to use your own charger, see Chapter 3: Technical Specifications. 2. Plug the flat end of the splitter cable to the T201 tag. 3. Attach the cable from the charger into the round plug of the splitter cable. 4. The green status LED will turn off once the charging is complete. This may take up to 6 hours depending on charger. You can use the tag normally while it is being charged, but the LED status lights are not displayed during charging. CHAPTER 2: Configuration Accessing the Configuration Interface (CLI) The T201 tag provides a Command Line Interface (CLI) for configuring its settings. The CLI can be accessed with the included serial cable. You need to configure at least each tag’s communication settings to let it associate with your Wi-Fi network and communicate with the Positioning Engine software. To configure a tag, follow these steps: 1. Plug the flat end of the splitter cable into the T201 tag. 2. Plug the 9 pin serial connector of the splitter cable to your laptop.
8 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. The acceptable line parameters are 9600,8,N,1, meaning 9600 bits/s, 8 data bits, no parity bit, and 1 stop bit. Flow Control must be set to “None”.
9 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. NOTE If the tag is already switched on, you may need to press the Enter key once or twice to bring up the CLI prompt.
10 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<Enter>.  Save the configuration changes to permanent memory by typing save<Enter>. Any unsaved changes will be lost during the next tag sleep or power-off period.  The command line is editable. You can move the cursor freely left and right and delete single characters from the line.  The command history is 10 previous input lines. You can scroll through the command history with up and down arrow keys  You can complete commands with the Tab key.  Type help<Enter> to display the list of available commands.  Successfully executed commands will not generate any output.  Invalid commands will display an error message.  The command prompt format is tag[serial number OR name]#
11 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”<Enter> tag[00001](unsaved)# save<Enter> Any unsaved changes will be lost during the next tag sleep or power-off period. Successful execution gives no feedback to the user. Most text parameters such as SSID and Engine password can be set without double quotes (“ “) if the text does not contain empty spaces. WEP key however always requires the double quotes, when typed in as plain text. The text itself cannot contain double quotes (“). Displaying Parameter Value Parameter values are displayed by typing the full parameter name string to the command line. E.g. displaying the motion scan rate: tag[00001]# motion scan rate<Enter> tag[00001]# motion scan rate = 2 seconds Error Messages If the user enters an invalid command, one of the two error messages may appear:  Parameter name not valid  Invalid parameter value E.g. setting an invalid parameter value tag[00001]# periodic scan interval -1<Enter> Error: Invalid parameter value
12 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. The name will be displayed in Ekahau Manager instead of IP address, and developers can read the names via Ekahau SDK and YAX device property GENERAL.NAME. Minimum configuration with example values: tag[00001]# wlan ssid 1 MyNetworkName<Enter> tag[00001]# wlan wep 1 “HaRdeR2HackeR”<Enter> (if WEP enabled) tag[00001]# engine ip 192.168.1.1<Enter> tag[00001]# ip method static<Enter> (if DHCP is not available) tag[00001]# ip address 192.168.1.2<Enter> (if DHCP is not available) tag[00001]# name Robert<Enter> (optional but recommended) tag[00001]# save<Enter> The simplest configuration with SSID and Engine IP address if DHCP is available and there is no WEP.
13 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<Enter> engine ip 192.168.1.1<Enter> wlan wep 1 26:4d:29:42:34:28:4d:69:44:30:24:4d:29<Enter> save<Enter> 2. Save the file for example as T201_settings.txt. 3. Connect a T201 tag to your computer and open a terminal program, such as HyperTerminal (see the previous chapters). 4. Select Transfer > Send Text File… If your terminal program supports several file transfer protocols, select ASCII. 5. Browse for the T201_settings.txt and click Send. Type config<Enter> to verify the new configuration. Changes from T101 Tags If you have used the Ekahau T101 tags, please note the following changes and modify your configuration scripts accordingly: • T201 supports up to 4 different wep keys. The index of the wep key has been added to the parameter ‘wlan wep key’. • T201 supports up to 4 different SSIDs. The index of the SSID has been added to the parameter ‘wlan ssid’. • The T201 does not support passive scanning. Scan mode passive parameter is not available.
14 Communication Parameters These parameters are required to let the tag associate with the Wi-Fi network and communicate with the Positioning Engine.

Configuration Tips This section provides tips that guide you in selecting the optimal configuration for your tags.  For best performance in accuracy it is recommended let T201 to scan two times before sending both results to engine. This improves Engines throughput and accuracy.  Ekahau recommends to use UDP protocol instead of TCP with larger amount of T201’s that frequently send data to the Engine. This is because of smaller overhead of the UDP protocol. Note that UPD protocol transmission is not guaranteed.  To save battery power it is recommended to always use "Sleep WLAN" option.  Ekahau recommends to use UDP protocol instead of TCP with larger amount of T201’s that frequently send data to the Engine. This is because of smaller overhead of the UDP protocol. Note that UPD protocol transmission is not guaranteed.  TCP protocol is recommended for applications were it is essential for the engine to receive all packets from the T201’s. TCP protocol transmission is always guaranteed.
26  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. How ever, if the signal of SSID index 1 is low enough, lower than -80dBm, the index 2 is tried to use and so on. This way T201 ensures that it establishes good connection to network even when the prior (index 1) network is audible with too low signal strength.  Following settings have proven to work well with the motion sensor: motion sensitivity = 3 motion poll interval = 0.200 seconds motion threshold = 5 motion dead time = 5.000 seconds CHAPTER 3: Technical Specifications Enclosure  Outside Dimensions (mm): 49 x 56 x 23  Weight (g): 85  Power switch with configurable Call button function  Tag and battery status indication with two 2-color LED  Buzzer for voice signals  Operating Temperature: 0 to 50 ºC [32…140ºF]  Storage Temperature: -10 to 70 ºC[-4…158ºF]  Humidity: From 20% to 90 % non-condensing, relative humidity  Environmental Protection: IP53/NEMA12, protected against dust and spraying water Wi-Fi  Supported Wi-Fi Specification: v1.1  Supported IEEE Standards: 802.11b/g/d
