1 OVERVIEW

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 IV 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 IV device located in the workstation. By

pressing the green button on the WhereCall IV 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 IV 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

IV 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.

The WhereCall IV may be mounted in a work area with removable fasteners, double-sided foam

tape or with mounting brackets and screws (Refer to Section 2.1, Installation and Mounting).

2 COMPONENTS

2.1 ISO 24730 System

The WhereCall ISO 24730 System consists of four major components: the WhereCall IV

device; a location antenna; a location processor and a ZES computer server. This document

details only the WhereCall IV device.

The WhereCall IV is a palm-sized device approximately 6.3 inches by 1.7 inches, 1.2 inch thick,

in a yellow case. A green colored actuator button is on the right side of the device. A liquid

crystal display (LCD) screen is located next to the button, near the center of the device.

The ZES Location Sensor (LOS) or Locating Access Point (LAP) receives radio signals from

the WhereCall IV device when the work station user sends a call requesting parts by pressing the

green button on the WhereCall IV. These signals are transferred from the LOS/LAP by

Ethernet or wireless backhaul to the VSS server. A message is generated by the server and sent

to the user’s computer system indicating that a part is needed at workstation initiating the

replenishment request..

If necessary, a WhereWand hand-held programming device allows the ZES technician to

configure the WhereCall IV device for custom applications. The WhereWand is not required

for most applications.

2.1 CCX System

The CCX System consists of four major components: the WhereCall IV device; CCX access

points; a wireless LAN controller and a location processor. This document details only the

WhereCall IV device.

The WhereCall IV is a palm-sized device approximately 6.3 inches by 1.7 inches, 1.2 inch thick,

in a yellow case. A green colored actuator button is on the right side of the device. A liquid

crystal display (LCD) screen is located next to the button, near the center of the device.

The CCX access points receives radio signals from the WhereCall IV device when the work

station user sends a call requesting parts by pressing the green button on the WhereCall IV.

These signals are transferred by cable to the wireless LAN controller.

The wireless LAN controller converts signals from the antenna(s) and sends them to the

location processor. The location processor passes the message through a VSS bridge to the

VSS server which send an alert to the user’s computer system indicating that a part is needed at

the location of the WhereCall IV device.

If necessary, the WhereWand hand-held communicator allows the ZES technician to configure

the WhereCall IV device. The WhereWand is not required for most applications.

3 INSTALLATION & MOUNTING

The WhereCall IV may be mounted in a work area with removable fasteners, double-coated

foam tape, hanging brackets, or with mounting screws. . The WhereCall IV display is optimized

for viewing at an angle perpendicular from the operator or from above. Mounting the WhereCall

IV above an operator’s eyelevel does not provide maximum contrast for the LCD display.

Each WhereCall IV 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 IV 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 IV, but is available from ZES in precut squares.

4 OPERATION OF THE WHERECALL IV

The WhereCall IV 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 IV 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 IV is on the OFF mode, the display shows PWR OFF . To turn the

WhereCall IV 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.

TFF-2220-00AA and TFF-2221-00AA User’s Guide D1436 Rev B

4.1 Call Mode

In CALL mode the WhereCall IV 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 IV will transmit blinks

with “Switch ID 0” which has status 2. The display on the WhereCall IV will flash CALL

for one minute and then start to count up in minutes since the call 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 after which it

will continue to alternate between CALL and 9d23h59m but the elapsed time will not

increment any further.

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.

TFF-2220-00AA and TFF-2221-00AA User’s Guide D1436 Rev B

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 IV 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

IV 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

4.7 Changing the WhereCall IV Batteries

Caution: Personnel changing batteries must use an ESD wrist strap to prevent damage of the

tag circuit board due to static discharge. Follow the manufacturer’s instructions for proper use

of the static prevention device.

4.7.1 Description

WhereCall IV 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 IV tags, the proper screwdrivers with the correct torque

settings must be used. This procedure must be followed or the WhereCall IV may become non-

operational. There is no field recovery method if this event 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.

8.2 WhereCall IV PLC Overview

This document describes how to mount and interface the WhereCall IV PLC to your equipment

via the external industrial connector.

The WhereCall IV PLC is a variation of the standard WhereCall IV. 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 IV PLC and the user equipment to operate

unattended and to send a call message via the ZES system.

For more information regarding the operation and installation of the

WhereCall IV PLC please refer to the WhereCall IV User Guide.

In this document the Terms WhereCall IV PLC and TFF-2221 are used interchangeably

and will have the same meaning.

8.3 WhereCall IV PLC Installation & Mounting

The WhereCall IV PLC may be mounted in a work area with removable fasteners, double-

coated foam tape, hanging brackets.

Each WhereCall IV 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 IV 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 IV PLC must not exceed 3 meters (10 feet).

8.4 Connecting the WhereCall IV PLC

The WhereCall IV 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 IV except that “button”

actuation is provided from another device.

8.4.1 WhereCall IV PLC Cable and Connector.

The TFF-2221 is to be connected using a Turck, RS 4.41T-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:

Turck USA

3000 Campus Drive

Minneapolis, MN 55441

1-800-588-8725

WWW.TURCK.COM

Other Turck locations are listed on the web site.

The cable length between the TFF-2221 and the remote device must not

exceed 3.0 Meters (10 feet).

ZES does not supply the cord sets and connectors for the WhereCall IV PLC.

WhereTag IV PLC Interface Cable Electrical Block Diagram

The cable should be connected and routed to prevent large voltage 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-2221 could be damaged.

CAUTION

Turck RS 4.41T-X

(Connect to WhereCall IV PLC)

The momentary switch will initiate blinks

when it is closed for 100 milliseconds and

then released. The switch must not

remain closed for more than 3.0 seconds

to avoid switching to power off mode.

8.4.3 WhereCall IV PLC Switch Operation

The switch used to operate the TFF-2221 must be a momentary type. The TFF-2221 will

initiate a “Button Blink” sequence when the switch breaks after having been closed for at least

100ms and less than 5 s. It the switch is closed for less than 100 ms the unit will not react. See

Table 1 for more information.

If the switch remains closed for three (3 seconds or more the unit will change to the “OFF”

mode.
