The right-hand column specifies which release SD card or online update releases must installed in which order in order to obtain the

desired release on the Tester. This applies particularly in case of a recovery or a new Tester.

Further information:

• The current base level software to use when restoring the PT3G is 39.900

• Essentially, it is only possible to update from an older release to a newer release.

• During the update, the system may automatically install intermediate releases before installing the final release. Example: If the Tester

is updated from release 39.300 to 39.400, the system automatically installs release 39.300 first, then the final release 39.400. If the

“required installation sequence” includes an online update, the information is applicable only if a newer online update is not already

available. Updates are always installed up to the newest available online update.

PIWIS Tester III “Recovery” using the BIOS

When you switch on PIWIS Tester III, a “Recovery” can be performed using the BIOS. This process resets the original image, including

the XP operating system and the PIWIS Tester III basic system features. The resultant system state is the basic system without

diagnostic content.

The Recovery process causes the system’s configuration data (e.g. network configuration, proxy settings, PPN certificate) to be lost

and as a result, the configuration parameters must be re-entered. After the Recovery process, a SD card of release version V2.000

or higher must be performed. The configuration must then be reset under “Settings - Network configuration”. Since the certificate is

no longer installed on the system, your PPN Coordinator can arrange for it to be made available for download again. You do not need

to apply for a new certificate. The imprint and boot password can be retained.

To perform the Recovery, restart PIWIS Tester III and press F2 during the boot process (Porsche logo appears). Then enter the

password “Porsche911” (the P in Porsche is uppercase), switch to the “Exit” tab, select “Repair your Computer” and then press

“Enter”. The Recovery process starts immediately (and takes approx. 35 min.). Press “Enter” when the Recovery is complete. PIWIS

Tester III restarts again. Select “Yes” to confirm the “Restore your Previous Data” dialog box. This saves the imprint as well as other

files you have created (e.g. screenshots, logs).
Online update, online teaching functions, PPN access, license update and data transfer

The “Online update”, “Online teaching functions”, “PPN access”, “License update” and “VAL data return” functions can only be run if

the network settings and any proxy settings that are used were set correctly and if a valid PC certificate was installed successfully

on PIWIS Tester II. The user must have PPN access and must be allocated to the certificate.

Note!

Please carry out the described configuration soon and in good time before the next online update release becomes available.
