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.
