1 OVERVIEW
The WhereNet 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 IIII 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 III device
located in the workstation. By pressing the green button on the WhereCall III 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.
There WhereCall III also operates in an optional “switch mode”. This mode can be
used to indicate a status; the display will blink either “-ON” or “–OFF” and will
toggle each time the button is pressed.
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 III device.
WhereCall III devices may be individually labeled for identification by applying a
user-supplied label to the recessed area on the front panel below the green button.
The WhereCall III 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).
