Section 9. CIRAS-3 Console and PC Utility

Software

The software provided for the operation of the CIRAS-3 is provided as two applications. One application

runs on Windows CE6 which executes on the CIRAS-3 main console. The file name is

“Ciras3_Console.exe”. The second application runs on desktop computers running Windows XP, Vista or

Win7 which have the .NET v2 libraries installed. The file name is “Ciras3_PC_Utility.exe”.

CIRAS-3 Console Software

Installation Instructions for Main CIRAS-3 Console

1. Insert the USB thumb drive (memory stick) provided by PP Systems into the USB port on the

CIRAS-3 main console (we recommend USB slot 2). The USB thumb drive is included with the

CIRAS-3 spares kit.

2. Open “My Device” and copy the “Ciras3_Console_vxxx.cab” file from the “CIRAS3_Console_SW”

folder to the root directory of the console file system. Note the exact location is not important as

the cab file will be erased when installation is complete.

3. Remove the USB thumb drive from console.

4. Right click on cab file and ensure it is not Write protected.

5. Double click on the cab file to execute the install. Accept all defaults by using the “OK” button.

6. When installation is complete, power off the console for a few seconds and then power it on

again. The new version of the console application should start automatically.

Uninstall Instructions

These instructions assume that the Ciras3_Console application was previously installed and that the

purpose of the new Install is to update the application. One should first uninstall the prior version of

Ciras3_Console.exe. It is easiest to do this via the use of a USB mouse attached to the console.

1. Open “My Device” on the console desktop. Navigate to folder:

2. “\Flash Disk\InstalledFiles\PP Systems CIRAS3_Console_v100”

3. Where “v100” is the prior installed version.

4. Copy “PP Systems CIRAS3_Console_v100.unload” file.

5. Navigate to “\Windows” folder and paste the unload file.

6. Close “My Device” window.

7. Use Start – Settings – Control Panel – Remove Programs. Select “PP Systems

CIRAS3_Console_v100” from the list and click “Remove” button.
