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.
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.
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”.
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.
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. 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 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]#
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.
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
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
Error: Invalid parameter value
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. 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
tag[00001]# wlan wep 1 “HaRdeR2HackeR” (if WEP enabled)
tag[00001]# engine ip 192.168.1.1
tag[00001]# ip method static (if DHCP is not available)
tag[00001]# ip address 192.168.1.2 (if DHCP is not available)
tag[00001]# name Robert (optional but recommended)
tag[00001]# save
The simplest
configuration with
SSID and Engine IP
address if DHCP is
available and there
is no WEP.
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.
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 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.
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.

Channels 1-13 are allowed in Europe, Middle-East, and Africa
Channels 1-14 are allowed in Japan
You can also limit the channels if certain channels are not used at all
in your network.
Set the allowed channels for example as: scan channels 1-3, 6-11.
Periodic Parameters
These parameters allow the tag to ‘wake up’ periodically, for example
every 2 minutes, perform a network scan, communicate the results to
the Positioning Engine, and go back to ‘sleep’ to save battery.

Motion Parameters
These parameters allow the tag to react to movement. Using these
settings wisely can significantly extend the tag’s battery life. It also
removes the need to query the tag location, as the tag will
automatically report its location whenever it is moved.
Special parameters are included for scanning after the tag has
detected that motion has ended. This is especially useful for asset
tracking applications.

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.
25
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 4: Care and Limited Warranty
Care and Maintenance
The tag is a product of superior design and craftsmanship and should
be treated with care. The suggestions below will help you to fulfill any
warranty obligations and to use this product for many years.
Keep the tag dry. Precipitation, humidity and all types of liquids or
moisture can contain minerals that will corrode electronic circuits.
Do not use or store the tag in dusty, dirty areas. Its moving parts
can be damaged.
Do not store the tag in hot areas. High temperatures can shorten
the life of electronic devices, damage batteries, and warp or melt
certain plastics.
Do not store the tag in cold areas. When it warms up (to its normal
temperature), moisture can form inside, which may damage
electronic circuit boards.
The operating temperature of the tag is 0 to 50 °C. Do not operate
the tag outside this temperature range.
Do not attempt to open the tag. Non-expert handling may damage
it.
Do not drop, knock or shake the tag. Rough handling can break
internal circuit boards.
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.
