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.
