STACK ST8100 Display System Chapter 1. Introducing the Display System
Users Guide 1
Chapter 1. Introducing the Display SystemChapter 1. Introducing the Display System
The Stack ST8100 Display System monitors and displays a range of
values, known as performance parameters, needed for effective car and
driver management in most competitive situations.
The system combines an analog tachometer with a digital display for the
following performance parameters:
1. Engine speed (RPM)
2. Oil pressure
3. Oil temperature
4. Water temperature
5. Fuel pressure
6. Battery Voltage
7. Wheel speed (optional)
8. Lap times (optional)
9. Lateral Acceleration (optional). This option is used only in conjunction
with the optional logging system. The information from it is not
displayed on the Display Module.
10. Maximum and minimum corner speeds display(optional)
You can view the peak values (tell-tales) for all the parameters.
The system provides a range of warning messages based on preset alarm
values for the following performance parameters:
1. Oil pressure
2. Oil temperature
3. Fuel pressure
4. Water temperature
5. Battery voltage
You can enable or disable the warning system for each parameter
individually.

Chapter 1. Introducing the Display System STACK ST8100 Display System
2Users Guide
You can redefine the preset alarm value for each parameter to a value
that is more suitable for your vehicle.
The system provides a gear shift warning light that is based on an RPM
value that you define for your vehicle.
How to Use this ManualHow to Use this Manual
Stack recommends that you unpack and connect the components in the
system before you install it in your vehicle. This will enable you to
familiarize yourself with operating the display and configuring it for the
vehicle in which you intend to install it.
This manual starts by taking you through the process of setting up the
system before installation, operating the digital display, configuring the
system and setting the alarm values, and installing it in the vehicle. By
the end of chapter 2, you will have set up the system so that you will be
assured that it is functioning normally. You can then read chapter 3 and
practice using its functions. Chapter 4 takes you through configuring it
for your vehicle. Chapter 5 explains how to install it in the vehicle.
Chapter 6 provides a set of trouble-shooting guidelines.
A template for the Display Module dashboard cut-out is provided in
Appendix A and a schematic diagram of the wiring harness is in
Appendix B.
Please note that this manual does not attempt to explain how to
interpret or use the information from the ST8100 Display System, as this
is very specific to the type of vehicle in which it is installed and the type
of competition in which the vehicle is engaged.

1. Connect the wiring harness to the Display Module.
2. Connect the four switches to the cables labelled S1 to S4.
3. Connect each of the sensors that you have purchased to the
appropriate wire in the wiring harness, as shown above.
4. Connect a 12v DC power supply to the power input cable.
5. Switch on the 12v DC power supply.
The Display Module should start up with an alarm signal indicating low
oil pressure.
This is normal in this environment.
You can now proceed to familiarize yourself with operating the Display

Chapter 3. Operating the Display SystemChapter 3. Operating the Display System
This chapter takes you through the operation of the system so that you
can familiarize yourself with its use before you install it in the vehicle.
Switching the Display System onSwitching the Display System on
You will have switched the system on already if you have followed the
instructions in the previous chapter and have just set the system up for
the first time before installing it.
When installed in the vehicle, the system is switched on when you switch
the ignition on.
When the power is first switched on, the digital display will immediately
show a "Low Oil P" warning and the alarm light will come on. The
tachometer will reset itself by moving the needle until it touches the
stop-pin, and then moving it back to the zero RPM position. Press Switch
3 to clear the warning message from the display. (Switch 2 can also be
used for this.)
The digital display panel and the analog dial face are always backlit
when the system is switched on.
If none of these actions occurs when you switch on, switch off the power
to the system and consult the section on troubleshooting in this manual.
Changing the display layersChanging the display layers
The digital display can show three separate sets of parameters and their
values; these are called display layer 1, display layer 2, 3 and 4.
If you have the Corner Speed option, there is an additional layer, layer 5,
which displays corner speed data.
Each of the display layers can be displayed in turn by pressing switch 3.
Press switch 3 when display layer 4, or layer 5 if you have the Corner
Speed option, is being displayed in order to return to display layer 1.
