1.4 WherePort III and WherePort IV

WherePort III and WherePort IV are proximity communication devices that are used to

trigger a WhereTag to transmit an alternate "blink" pattern. When a WhereTag passes

though the WherePort's field, the tag can initiate a pre-programmed and (typically) faster

blink rate to allow more location points as a tagged asset passes through a critical threshold,

such as a shipping/receiving dock door or from one zone to another. When the WhereTag is

sending WherePort-initiated blinks, the tag includes the identification number of the

WherePort.

1.5 WhereWand Handheld Programmer

The WhereWand Handheld Programmer consists of a handheld computer with an integrated

Type II PC card and an antenna assembly. The WhereWand is capable of two-way wireless

communication with WhereTag devices. The WhereWand is also capable of wired

communication with WherePort devices. The third capability of the WhereWand is wireless

communications with the WhereLan. The WhereWand communicates with WhereTag

devices by sending magnetic FSK data to the tag and receiving on-off keyed / frequency

shift keyed (OOK/FSK) RF data from the tag. Communication with the WhereTag 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.

1.6 Visibility Server Software (VSS)

Zebra Visibility Server Software (VSS) is an integrated software package that provides all

the tools required to effectively manage assets and resources as well as the Zebra Real-

Time Locating System (RTLS). Visibility provides all core software components to allow

efficient resource management. Key among those software components is WhereSoft

Locate, which is a distributed Windows® Service. When WhereSoft Locate is combined with

VSSand any of the many applications available from Zebra, it is possible to locate assets,

know their status, and react to any number of user configurable alert conditions. Visibility
