1.2 RF Notice

The antenna used for this transmitter must not be co-located or operating in

conjunction with any other antenna or transmitter.

Any changes or modifications to WhereNet Corporation equipment not expressly

approved by WhereNet Corporation could void the user’s authority to operate the

2 SYSTEM OVERVIEW

2.1 WhereNet RLTS System

The WhereNet real time location system (RTLS) is designed to permit users to

determine the position of tagged assets in both indoor and outdoor applications.

Each WhereTag autonomously emits a 2.4 GHz direct sequence spread spectrum

(DSSS) radio signal at predetermined blink intervals, in response to switch events,

and/or in response to WherePort devices. The signal transmitted by the WhereTag

is received by the WhereNet infrastructure which decodes that tag’s transmission,

extracts the data, and determines the tag’s location using several different

algorithms.

___________________________________________________________________________

WhereWand II User’s Guide

___________________________________________________________________________ 11

WhereWand II User’s Guide D1258 rev A

WhereNet Confidential

The WhereNet RLTS consists of WhereTag/WhereCall tags, WherePorts,

WhereWands, Location Sensors, and the server based Visibility Suite software.

WherePorts generate a magnetic field in a localized area. WherePort devices can

be used in places where the user wants to know immediately that the tagged asset

has entered the zone covered by the WherePort field. The WhereTag devices can

be configured to blink rapidly several times when they enter a WherePort field.

When the tag blinks in response to entering a WherePort field, the ID of the

WherePort is included in the tag transmission.

WhereWands are used to configure WhereTags, WhereCalls, WherePorts, and

Location Sensors. This document will detail the operation and use of the

WhereWand.

Location Sensors receive DSSS blinks from the tags and demodulate the signal,

time stamp the blink, and send the tag ID and any associated data included in the

blink to the server over the LAN.

2.2 WhereWand Hand Held Programmer

All references to the WhereWand product in this document assume VSS 3.0

(or greater) Tag Utilities are loaded on the WhereWand; prior versions of the

Tag Utilities do not support all features listed in this document.

WhereWand II User’s Guide D1258 rev A

WhereNet Confidential

The WhereWand Hand Held Programmer consists of Handheld Computer with an

external WhereWand adapter with an integral antenna assembly. The WhereWand

is capable of two-way wireless communication with WhereTag and WhereCall tag

devices. The WhereWand is also capable of wired communication with

WherePort devices. The third capability of the WhereWand is wireless

communications with the Location Sensor in the WhereNet G2 infrastructure.

The WhereWand communicates with WhereTag II/III/IV devices by sending

magnetic FSK data to the tag and receiving on-off keyed / frequency shift keyed

(OOK/FSK) RF data from the tag. The WhereWand communicates with

WhereCall and WhereTag I devices by transmitting and receiving OOK/FSK RF

data to and from the tag. Communication with the WhereTag and WhereCall

allow the user to set tag configuration parameters such as DSSS blink intervals and

tag responses to such stimuli as WherePorts and/or switch/telemetry inputs. It also

allows the user to read back configuration and other data from the tag. The

WhereWand will automatically select the proper communication protocol scheme

based on the tag’s unique identification number

 Tag IDs between 0 and 16,777,215 are WhereCall or WhereTag I

 Tag IDs between 16,777,216 and 17,099,999 are WhereTag II V2.0

 Tag IDs between 17,100,000 and 17,999,999 are WhereTag II V2.1

 Tag IDs greater than 18,000,000 are WhereTag III or IV devices

The WhereWand communicates with WherePort II or III devices using the

configuration cable included with the WhereWand. This bi-directional interface

___________________________________________________________________________

WhereWand II User’s Guide

___________________________________________________________________________ 13

WhereWand II User’s Guide D1258 rev A

WhereNet Confidential

allows the user to configure WherePort devices and read back the configuration.

WherePort configuration parameters include WherePort ID, power level, phase

setting, and tag response.

The WhereWand communicates with the Location Sensor by transmitting DSSS

messages containing the desired configuration data or test mode. This is a transmit

only operation and the Location Sensor will not transmit anything back to the

WhereWand, but the Location Sensor will flash its LEDs to indicate

communications are in progress.

2.3 Power Management

The WhereWand II’s power management is handled by the application software

installed on the handheld computer. The WhereWand II Adapter PCBA itself will

shut off the on-board high frequency RF clock while it is not transmitting to

further reduce current consumption. The WhereWand II Adapter ships with

rechargeable Lithium batteries.

Any time the WhereWand Programmer is not in use, it should be placed into its

battery charger cradle. Refer to the terminal’s Original Equipment Manufacturer

documentation included with the product.

4.2.4 Custom Configuration WherePort Retrigger

Selecting <D> WP Retrigger from the custom configuration screen 1 will allow

the user to set the WherePort retrigger timeout and mode. The same WherePort ID

will be ignored after causing tag blinks until the retrigger timeout expires. The

mode selects the event that starts the timer. In retrigger mode 1 (values with ‘L’

added to the time in seconds) the retrigger timer starts after the tag sends its last

WherePort blink from the previously received valid WherePort message. In

retrigger mode 2 (values with ‘E’ added to the time in seconds) the retrigger timer

will not start until the sends its last WherePort blink AND the tag has left the

WherePort field. If the same WherePort message is received before the timer

expires, the time is reloaded and the retrigger timeout starts over. In retrigger

mode 3 (values with ‘EF’ added to the time in seconds) the retrigger timer operates

the same as in mode 2, only when the timer does expire, the tag will send another

set of WherePort blinks – with the “LEFT WP FIELD” bit set. The retrigger times

can range from 1 second to 2 minutes. As soon as the user selects one of the

available timeouts, the WhereWand application will return to custom configuration

screen 1 to allow another parameter to be selected and modified. The user can

press <Enter> to move to between the WherePort retrigger pages, or <ESC> to

return to the previous menu. Anytime the tag enters the field of a different

WherePort, the blinks and retrigger from the previous WherePort are aborted and

the process begins for the new WherePort. Figure 14 shows the flow diagram of

the blinks and retrigger for one WherePort. Figure 15 shows the available

retrigger times. This configuration parameter applies only to tags with ID greater

than 17,000,000.

Most applications will use <F2> or length 27. This will support any WherePort ID

between 0 and 32,767. The message also includes the tag response information to

select between 72-bit or 152-bit tag blink response. The 15-bit WherePort ID is

added to the normal tag blink. The tag’s 4-bit status will always be 1000. This

message only works with WhereTag V2.1 tags.

<F3> or length 43 will support any WherePort ID between 0 and 32,767. The

message also includes the tag response information to select between a 72-bit or

152-bit tag blink response. The 15-bit WherePort ID is added to the normal tag

blink. The tag’s 4-bit status will always be 1000. This message also includes

limited tag configuration parameters. The parameters include:

Number of WherePort Blinks (0 through 15)

WherePort Blink Interval (5 seconds to 1 minute)

WherePort Retrigger (1 second to 2 minutes, three modes)

These parameters will permanently overwrite the existing tag configuration. This

message only works with WhereTag V2.1 tags.

<F4> or length 143 is used to send the tag 12 bytes of data. The data is the entire

WherePort message, so there is no associated WherePort ID in the tag blinks. This

message only works with WhereTag V2.1 tags.

5.3.4 Configure WherePort Power

Selecting <D> from the set WherePort configuration screen allows the user to

select from one of eight power levels. The maximum power setting 8 will give

about a 20 foot range. The minimum power setting 1 will give about a 3 foot

range. Care should be taken when setting the power to avoid under covering an

area, or over covering an area and having the signal bleed into undesired areas.

Figure 37 shows the WherePort power screens.

Figure 37: WherePort Power

Table 3 outlines the WherePort to Tag range for the power levels. Since the range

is dependent on the tag orientation in the WherePort field, the table defines 3

zones. The green zone is the range at which the tag will always see the

WherePort, regardless of orientation, as it passes through the zone. The yellow

zone will typically work, but the tag may not receive the WherePort message if it

is oriented poorly in relation to the field. The red zone is an area that the tag will

5.3.5 Configure WherePort Phase

Selecting <E> from the set WherePort configuration screen allows the user to set

the phase of WherePorts when multiple WherePorts are connected to provide a

larger area of coverage.

The phase of a single WherePort should always be set to 0°.

When multiple WherePorts are connected, the first WherePort in the chain should

always be set to 0°. WherePorts facing the same direction should have the same

phase, and every 90°change in the mounting direction should correspond to a 90°

phase change. Figure 38 shows the WherePort phase setting screen. Figure 39

shows an example of the phase setting in a typical multi-WherePort installation.

The WhereWand communicates with the Location Sensor by sending DSSS blinks

containing the MAC address of the Location Sensor. The first screen the user sees

is a prompt for the Location Sensor’s MAC address. This can be manually typed in

using the WhereWand keypad, or scan from the Location Sensor bar code label

using the WhereWand laser scanner. The bar code label is located on the back of

the Location Sensor and in the site design document. Figure 42 shows the MAC

address entry screen.

Important: If the MAC does not start with 0004F1, all LS operations will result

in an error. This is a safety feature to prevent unnecessary transmissions from the

WhereWand.

Alternately, the user can enter the System Builder ID for that Location Sensor.

This will access the file LocationSensors.txt on the WhereWand to get the MAC

address.

Important: The LocationSensors.txt file should be in directory C:\Program

Files\WhereNet\PDT\PDTInstall\link directory prior to running PDT install.

Important: This LS configuration operations consume a significant part of the
