a power manager. Power manager blocks for a short time - in the BIOS-Setup
the CPU. Because of this the precision of time administration - in the file CONFIG.SYS (example Power.exe)

- under properties → system options → energy.
This may result in error reports. In order to prevent this, you
can switch of the power manager.

RS232 Hardware Interface

The communication interface cable between the computer Figure 1: RS232 cable
and the digital controller is a RS232 cable. Only the RxD,
TxD and GND signals are needed (see figure 1).
PIN 2: TxD
PIN 3: RxD PIN 2: TxD
CAUTION PIN 5: GND PIN 3: RxD
It is only allowed to connect RxD, TxD and GND. PIN 5: GND
With a standard RS232 cable you can damage your
computer under certain conditions.

Theory of Operation
Starting the WinGPI Software Figure 4: First Screen (Example)

1. Ensure that the digital system and the computer are

both switched off.

2. Connect the computer to the digital controller with the

RS232 interface cable.

3. Turn on the computer.

4. Start WinGPI.
For some seconds the current software version number
and the “start screen” with the SAUER-SUNDSTRAND
logo appears.

The screen of the WinGPI is divided in one text window and
in graphic windows.

The Text Window

In this area the WinGPI displays alphanumeric data.

The Graphic Windows

There are two kinds of windows: Analog windows that
show a simple analog instrument and XY windows that
show a XY plotter.
6. Turn on ignition to give power to the digital controller.

Load TCF-File

After you pressed this menu item, you can select a TCF-file
to load. You also can specify a TCF-file in the Command-
Line and WinGPI will load this one automatically while
starting.

• After successful download of the HEX-file the digital

system starts operating and the opening screen appears.

Edit TCF-File

If you are authorized, you can select this item and edit a
TCF-file. Kernel Download

If you are authorized, you can select this to download a

Kernel HEX-file to the digital controller. The Kernel file type
Application or Default Parameter Download has to be *.hex or *.ker. You also can specify a Kernel HEX-
file in the Command Line and WinGPI will start the download
It is possible to reprogram the digital system. Use this directly you power on the digital controller. If your selected
menu item or the short cut , before starting the file type is *.hex, you have to specify the command line

WinGPI will start the download directly you power on the
digital controller.

Also you can use the short cut , during running Run CAUTION

interrupt this process (i.e. switch off the ignition).

Connect

Select this menu item to connect WinGPI with the digital

controller (Open Com-port). When you start the WinGPI
program, WinGPI connects automatically to the digital
controller with the selected Com-Port and the default
baudrate 19200 Baud.

Different ways to specify the Com-Port which you want to

use:
• specify the Com-Port in the Command Line
• specify the Com-Port in the Terminal Control File
• specify the Com-Port in the INI-File

These declarations have a different priority. The highest

priority is the declaration in the command line. This
Com-Port will use the whole time as you run this program,

If no Com-Port is specified in the command line WinGPI
use the declaration from the INI-file. But if another Com-
Port is declared in the TCF-file WinGPI use this one and
save this in the INI-file.
