Micros Client Application Loader; New Ws4 Installation; Day-To-Day Operation - Micros Systems Workstation 4 Setup Manual

MICROS Client Application Loader (CAL)
The CAL plays a key role in managing the installation and ongoing
maintenance of the Workstation 4 POS application software. The CAL consists
of two parts. One part resides on the WS4, (CAL Client) and the second part
resides on the system server (CAL Server). The CAL Server is installed along
with the POS Application. This document describes the CAL Client and its
role in setting up a new workstation and maintaining the application software
on a day-to-day basis.

New WS4 Installation

When a new WS4 is connected to the system LAN, and powered up for the
first time, the CAL starts through a Windows CE Registry setting. The first
time it starts, it checks the system registry and determines that the
workstation is not yet configured. It broadcasts a Universal Datagram
Protocol (UDP) discovery request and displays a User Interface (UI) that
contains the name of any server that responds.
The UI displays the CAL server name, along with the Server Application
Type (3700, 9700, or 3rd party - in most installations there will be only one
CAL server). When the CAL server is selected, the installer is presented
with a list of workstations, pre-programmed in the application's device
database.
When the installer selects a workstation from the list, the WS4 name and
TCP/IP network configuration (DHCP or Static IP Address) are entered in
the workstation's registry. The CAL then transfers the application
'package' consisting of the application and support files. A CAL server
configuration file called SETUP.DAT specifies the name of each file to be
transferred as well as its destination. All application and support files are
placed on the CF Card.
When the transfer is complete, the CAL forces a restart. After the restart,
the CAL again checks the registry settings and this time determines that an
application is installed. It starts the application and uses the TCP/IP
network configuration to establish a LAN connection with the server.

Day-to-Day Operation

If the WS4 is powered off each night, or should AC power fail, the CAL
client is responsible for re-starting application software when the WS4 is
powered up.
As the WS4 operates on day-to-day basis, the CAL remains in the
background, periodically checking the server for updated versions of the
application, operating system or a newer version of the CAL itself.
