The Zebra Enterprise Solutions (ZES) WhereCall System allows users in manufacturing and
assembly operations to request service or specific parts without leaving their workstations.
Specific parts or service requests may be assigned to individual WhereCall V devices so
that users may indicate which item is needed. For example, an assembly worker using
several parts: Each part is associated with a separate WhereCall V device located in the
workstation. By pressing the green button on the WhereCall V device, a radio signal is sent
by the WhereCall System to the computer system in the supply area, indicating which
workstation requires the specified part or service. The display will first blink CALL , and
then alternate between CALL and the time since the button press. This message can
be customized to site preferences.
The WhereCall V also operates in an optional SWITCH mode. This mode can be used to
indicate a status; the display will blink either -- ON -- or - OFF -- to indicate a functional
status. The status will toggle each time the button is pressed. These messages can also be
customized to site preferences. Each status can display a multi-word message on up to two
different screen buffers.
To insure that the WhereCall system is in constant operation, real-time monitoring using an
“I’m Still Alive” blinking transmission advises the system supervisor of the status of each
WhereCall V device. Battery status is also included in these “I’m still alive” messages as
well as in the switch blinks, as well as in the button initiated blinks.
WhereCall V devices may be individually labeled for identification by applying a usersupplied label to the recessed area on the front panel below the green button.
The WhereCall V may be mounted in a work area with removable fasteners, double-sided
foam tape or with mounting brackets and screws. Overhead installation is also possible by
using cable mounting (Refer to Section 3, Installation and Mounting).
The WhereCall System consists of four major components: the WhereCall V device; a
location antenna; a location processor and a ZES computer server. This document details
only the WhereCall V device.
The WhereCall V is a palm-sized device approximately 3 inches by 5 inches, 1 inch thick, in
a yellow and gray colored case. A green colored actuator button is in the center of the
device. A liquid crystal display (LCD) screen is located above the button.
The ZES Location Sensor receives radio signals from the WhereCall V device when the
work station user sends a call requesting parts by pressing the green button on the
WhereCall V. These signals are transferred by cable to the ZES Location Processor.
The ZES Location Processor converts signals from the antenna(s) and sends them to the
ZES computer server. A message is generated by the server and sent to the user’s
computer system indicating that a part is needed at the location of the WhereCall V device.
If necessary, the WhereWand hand-held communicator allows the ZES technician to
configure the WhereCall V device. The WhereWand is not required for most applications.
The WhereCall V may be mounted in a work area with removable fasteners, double-coated
foam tape, hanging brackets, or with mounting screws. Overhead installation is also
possible using cable mounting.
Each WhereCall V must be mounted in a location to provide an unobstructed view in at least
one direction. To maintain communication with the Location Antennas, do not install the
WhereCall V inside a metal enclosure such as a metal cabinet.
3.1 Poly-Lock
A plastic, adhesive-backed fastener, Poly-Lock uses mushroom-shaped contact points that
overlap and snap together, forming a strong attachment that can be separated by a forceful
pull. Poly-Lock is not included with the WhereCall V, but is available from ZES in precut
squares. Contact your ZES account manager for information.

fastener locations on the mounting surface.
5) You should now have four pairs of Poly-Lock attached to the back of the
WhereCall V. Remove the adhesive backing from all four squares.
6) While holding the WhereCall V, aligned with the fasteners on the
mounting surface. Gently press the unit against the mounting surface to
assure that the adhesive on the squares is bonded to the both surfaces.
3.3 WhereTag Foam Tape Squares
WhereTag foam tape, both sides adhesive, provides a secure, semi-permanent mounting
method for the WhereCall V device. Foam tape is not included with the WhereCall V.
Contact your ZES Account Manager for information.
“Double sticky” tape applies a layer of permanent adhesive film to both
surfaces. Care should be taken in the application of foam tape; once applied it
is difficult to remove.

The WhereCall V is a wireless messaging device that is capable of transmitting simple
messages to the ZES Infrastructure. These messages can range from a call for parts for
line side material replenishment to a request for supervisor assistance. There are three
modes of operation:
Button or CALL Tag Mode
Messaging or SWITCH Tag Mode
OFF Mode
The WhereCall V is shipped in the “OFF” mode. There is also a battery change mode
that is used to condition the tag to for installation of replacement batteries.
When the WhereCall V is on the OFF mode, the display shows PWR OFF . To turn the
WhereCall V on when it is in the OFF mode, press the button once and the tag will
resume operation in either the CALL mode or the SWITCH mode depending on the
mode it was in when the OFF mode was selected.
4.1 Call Mode
In CALL mode the WhereCall V can be used for parts call and other operations that do
not require an indication as to whether the request was fulfilled. In this mode, the
operator presses the button to send the request message, and the WhereCall V will
transmit blinks with “Switch ID 0” which has status 2. The display on the WhereCall V
will flash
was made. This lets the operator easily verify how long it has been since they made their
request. The display is capable of counting up to 9 days, 23 hours, and 59 minutes
shown as
9d23h59m but the elapsed time will not increment any further.
CALL for one minute and then start to count up in minutes since the call
9d23h59m after which it will continue to alternate between CALL and
The displayed CALL can be replaced with any other 8-character custom message.
The custom message will blink for one minute after each button push, and then the
custom message will alternate with the elapsed time.
4.2 Switch Mode
In switch mode, the display toggles between -- ON -- and -- OFF --. The normal
starting state is OFF. If the operator presses the button, then the WhereCall will send a
message signaling the change in state and the display will change to -- ON --. The
resulting transmission blink includes “Switch ID 0” which has status 2. The next button
press will cause a new message to be transmitted with “Switch ID 1” which has status 4.
This signals the change of state and the display will change back to - OFF --. In the
SWITCH mode the WhereCall V will send multiple transmissions at increasing intervals
after each button press. The first set of blinks occurs as soon as the button is pressed,
then repeats at 1 minute after the button press. The message is then repeated at the
following periods after the initial button press: 5 minutes, 10 minutes, 15 minutes, and
then 30 minutes.. After completing that sequences, the WhereCall V then continue
sending a set of blinks every 60 minutes.
The displayed -- ON -- and - OFF – messages can be replaced to show any one or a
pair of 8-character custom messages. If the message is replaced with a pair of custom
messages, then the display will not flash, but instead alternate between the pair of
custom messages. When the button is pressed, the display will alternate between the
other pair of messages.
The WhereCall V can be switched to the Power OFF mode from either CALL mode or
SWITCH mode. In order to do this, press and hold the button until the display shows
******** and then release the button. The display will show the tag firmware version
TAG 2109 for a few seconds and then show the PIC Microcontroller firmware PIC 1017
version for a few seconds, the show PWR OFF . Note that the displayed version number
may differ than those shown above. The WhereCall V is now OFF and all transmissions
are disabled. The magnetic receiver in the tag is also disabled.
4.4 Switching WhereTag V Modes
To change modes between CALL mode and Switch mode or visa versa, press and hold the
button. After about 5 seconds, the display will show ********. DO NOT release the button
while the display shows *********, but continue to keep the button depressed until the
display shows:
- CALL ? if the WhereCall V is currently in SWITCH mode
- SWITCH ? if the WhereCall V is currently is CALL mode.
When either of these is displayed, release the button , and then press and release the
button again within five seconds. This will change the operational mode.
If the WhereCall V has been changed from CALL mode to SWITCH mode, the tag will send
SW ID 1 with status 4 and the display will show
- OFF --.
If the WhereCall V has been changed from SWITCH mode to CALL mode, the tag will send
SW ID 0 with status 2 and the display will show CALL .
To change the WhereCall V mode between ISO 24730, CCX, and dual mode, the
WhereCall V must be in OFF mode and display
PWR OFF . Press and hold the button for
several seconds until the display starts to cycle between these options…
ISO MODE, CCX MODE, DUALMODE, and CNG BATT.
To switch to ISO 24730 mode, keep the button pressed until the display is showing
ISO MODE, then release the button, then click the button again to activate the mode. This
mode will disable all CCX blinks and the WhereCall V will only send ISO 24730 blinks. In
ISO 24730 mode, the decimal point in the lower right most corner of the LCD will flash.
To switch to CCX mode, keep the button pressed until the display is showing CCX MODE, then
release the button, then click the button again to activate the mode. This mode will disable
all ISO 24730 blinks and the WhereCall V will only send CCX blinks. In CCX mode, the
apostrophe in the upper left most corner of the LCD will flash.
To switch to dual protocol mode, keep the button pressed until the display is showing
DUALMODE, then release the button, then click the button again to activate the mode. In this
mode, the WhereCall V send both ISO 24730 and CCX blinks. In dual protocol mode, both
the decimal in the lower right most corner and the apostrophe in the upper left most corner
of the LCD will flash.
If the user has inadvertently released the button at the wrong time and the WhereCall V is
displaying the wrong mode, do not click the button again. The tag will timeout and return to
OFF mode and the display will show
The WhereCall V supports soft messaging which allows the user to replace the displayed
messages
CALL , - - ON - - and/or - OFF - - with custom messages. Setting or
changing the soft message will require a WhereWand to enter and program the messages
to the WhereCall V magnetically.
If a custom message is configured in CALL mode, then the custom message will be
displayed. , instead of CALL blinking or alternating with elapsed time, There is no
change to the air protocol blink content .
In SWITCH mode, each of the two messages can be replaced with a single message or a
pair of messages.
If custom messages are configured and the WhereCall V is in the SWITCH mode ON state,
instead of - - ON - - blinking, the display will either blink the custom ON mode single
message or alternate between the pair of custom ON mode messages.
If custom messages are configured and the WhereCall V is in the SWITCH mode OFF state,
instead of
- OFF - - blinking, the display will blink either the custom OFF mode single
message or alternate between the pair of custom OFF mode messages.
A variant of WhereCall V, the WhereCall V PLC, provides for automated call requests by
replacing the call button with a sealed connector that can be interfaced to intelligent shop
floor equipment.
The WhereCall V provides long battery life, typically in excess of 5 years. Additionally, the
batteries are replaceable providing a long product life.

This document describes how to mount and interface the WhereCall V PLC to your
equipment via the external industrial connector.
The WhereCall V PLC is a variation of the standard WhereCall V. It allows the call tag to be
used with a remote switch in external equipment. The external equipment can “press the
button” to initiate a call. This enables the WhereCall V PLC and the user equipment to
operate unattended and to send a call message via the ZES system.
Figure 8: Photograph of the WhereCall V PLC with an interface cable attached.
(This cable is not included with the WhereCall V PLC.)
For more information regarding the operation and installation of the
WhereCall VPLC, please refer to the WhereCall V User Guide.
In this document the Terms WhereCall V PLC and TFF-2236 are used
interchangeably and will have the same meaning.
The WhereCall V PLC may be mounted in a work area with removable fasteners, doublecoated foam tape, hanging brackets, or with mounting screws. Overhead installation is also
possible using cable mounting.
Each WhereCall V PLC must be mounted in a location to provide an unobstructed view to a
location antenna in at least one direction. To maintain communication with the Location
Antennas, do not install the WhereCall V PLC inside a metal enclosure such as a metal

cabinet.
In selecting the mounting location keep in mind that the cable from the equipment
to the WhereCall V PLC must not exceed 3 meters (10 feet).
The WhereCall V PLC can be connected to a remotely mounted switch that is used to
initiate a “button blink”. This product works very much like the WhereCall V except that
“button” actuation is provided from another device.
8.1 WhereCall V PLC Cable and Connector.
The TFF-2236 is to be connected using a Turck, RS 4.4T-X cord-set. The length of the
cable is limited to 3.0M (10 feet). When this cord set is used the connection will be
watertight.
This cord-set can be purchased from:
1.The connector on the WhereCall III+ PLC may not be oriented as
Notes:
2. The Cord is not supplied by WhereNet. Please see instructions.
3. The momentary switch will initiate a "button Blink" when it is
closed for 100 milliseconds and then released. The switch must not
remained closed for more than 3.0 seconds or the tag will
transition to the OFF mode .

spikes and static discharges from being carried into the tag via the
switch cable. This may result in false “Button Calls” being generated or
in extreme cases the TFF-2236 could be damaged.
The switch used to operate the TFF-2236 must be a momentary type. The TFF-2236 will
initiate a “Button Blink” sequence when the switch breaks after having been closed for at
least 100 ms and less than 5 seconds. It the switch is closed for less than 100 ms the unit
will not react. See Table 1 for more information.
_________
Note
________
If the switch remains closed for three (3) seconds or more, the unit will change to
the “OFF” mode.
WhereCall V Tags have a nominal battery life of 5 years. After that nominal battery life, it is
possible to replace the batteries to extend the life of the tag itself; however, ZES does not
provide personnel or Services for this process.
To avoid damaging the WhereCall V tags, the proper screwdrivers with the correct settings
must be used. This procedure must be followed or the WhereCall V may become nonoperational and there is no field recovery method if this occurs. Batteries should be replaced
before they are completely dead.
ZES assumes no responsibility for damage to or failure of the WhereCall Tags resulting
from this battery replacement procedure.
