Warning:
Installation of the TC100/200 requires modifications to be made to
your vehicle’s electrical system. If this is not done correctly, expensive
damage may be caused to both the product and your vehicle. It
is strongly recommended that you seek the services of a qualified
automotive electrician to carry out this work.

Step 1: Before You Start
Check that you have the items shown below. You will also need a selection of
tools, wiring sundry, and a safe place to work.
(A) Rally Computer; (B) Wiring Loom; (C) Speed Sensor

Step 2: Fitting to the Vehicle
Securely attach the Rally Computer to the interior of your vehicle. The most
common locations for this are either on the dashboard or passenger door
frame.
When fitting the device, ensure that:
It will not come free of its mounting during an accident. There are two•
M4 bosses on the back that can be used to fasten it securely.
It does not interfere with any of the vehicle’s safety equipment.•
The co-driver can operate it comfortably while seated.•
Warning: If the vehicle still has airbags fitted, do not place the device over the
covers from which these are deployed. Doing so could result in serious injury in
the event of a collision.

Step 3: Electrical Connections
All connections to the Rally Computer are made through the color-coded wiring
loom supplied with it. Connect this loom to your vehicle’s electrical system as
shown in the wiring diagram.

Connect to a 12 Volt power source that is
able to supply power when the ignition is
turned off.
Use a common ground point for all parts of
the circuit. Do not use the vehicle’s chassis.
(Optional) Attach up to two hand or foot
switches to use the Auxiliary Inputs. See
Page 11 for more details.

Fuel Sender Signal (TC200 only)
To use the TC200’s fuel measurement system, connect the output signal from
your vehicle’s fuel sender directly to the green wire on the loom.
Points to note during installation are:
The TC200 works by measuring the output voltage of your vehicle’s fuel•
sender. It can be used with signals that either rise or fall with increasing
fuel level.
In most situations the TC200 will not interfere with the operation of your•
existing fuel gauge.
If you remove your factory fuel gauge you will need to fit a resistor of•
approximately the same value in its place.
Many factory fuel senders will not produce an output signal when the•
ignition is turned off.

Speed Sensor
This generates the signal used by the Rally Computer to measure speed and
distance. You should have selected a Monit Speed Sensor to suit your vehicle
when you purchased the product.
For detailed installation instructions, refer to the information supplied with your
sensor.
Auxiliary Inputs
These can be used to attach up to two hand or foot switches to the Rally
Computer. You can then configure each switch to perform a range of useful
functions, such as clearing the distance or controlling the stopwatch. Any
type of switch can be used.
See page 28 for more information.

Step 4: Final Checks
Before you apply power to the system check that all your electrical connections
are correct. Also make sure that any exposed wires in the circuit are covered
with insulation tape or heat-shrink.

The TC100/200 works in a similar way to a portable music player
or mobile phone and is designed to be very easy to use. Read this
section to quickly learn how to perform a calibration, view vehicle
data, and access commonly used features.

14 Quick Start
User Interface Basics
The Rally Computer’s user interface consists of a graphics screen surrounded
by four buttons. When the device starts up you will see the following image on
the screen.
On the left and right edges of the screen there are two vertical bands that
contain text labels. The purpose of these is to indicate what functions are
currently assigned to each of the buttons. These will change as you move
around the menu system.

15Quick Start
Telemetry Menu
This appears when the device first starts up. It allows you to easily view your
vehicle’s distance, speed, timing and fuel information, and is the menu you will
use most of the time.
The upper half of the menu always shows the Interval Distance Counter. Use
the upper right CLR button to reset this instantly. The lower half is used to
show all other speed, distance, timing and fuel parameters for your vehicle.
Use the MODE button to cycle through these.
The various parameters available are shown on the next page.

Counter

16 Quick Start
Total Distance Counter
Second distance counter. Hold the CLR button down
for one second to reset.
Current Speed
The current vehicle speed in kph or mph.
Average Speed (TC200 only)
The average vehicle speed since the function was last
reset. This includes any time spent stationary. Hold the
CLR button down for one second to reset.
Maximum Speed
The maximum vehicle speed. Hold the CLR button
down for one second to reset.
Stopwatch
Integrated stopwatch. Use the STRT button to start
and stop timing. Hold the same button down for one
second to clear the time.

17Quick Start
Time of Day (TC200 only)
The current time in 24-hour format. Use the SET button
to adjust the value.
Fuel (TC200 only)
The current fuel level in litres or gallons. When the
vehicle is moving the value may fluctuate as the fuel in
the tank moves about.
To reduce clutter, you can disable parameters that you do not want to use. See
page 24 for more information.
Note: Some parameters are disabled by default. You will need to enable them
before they can be selected using the MODE button.

18 Quick Start
Menu System
You can use the Rally Computer’s powerful menu system to quickly adjust
settings and access advanced features. Press the MENU button when in the
Telemetry Menu to enter the menu system.
Use the two buttons on the right to navigate through the menu options, and the
OK button to make a selection. You can return to a previous menu at any time
by pressing the BACK button.

19Quick Start
Distance Calibration
Before you can use the Rally Computer to measure distance, you will need
to perform a calibration. The device includes a special calibration wizard that
guides you through this process using simple on-screen instructions.
To calibrate the distance:
Find a piece of road with an accurately known distance. Use a distance of1.
at least one mile/kilometre for best results.
From the Main Menu select Calibration > Cal. Distance to start the2.
calibration wizard.
Follow the instructions on the screen.3.
Note: The device will not lose its calibration if the power supply is disconnected.

20 Quick Start
Fuel Calibration (TC200 only)
The TC200’s fuel measurement system is designed to work with a wide range
of tank sizes and shapes. Before it can be used, the system must be calibrated
to suit your particular vehicle. This is done using a special calibration wizard
that guides you through the process using simple on-screen instructions.
To calibrate the fuel system:
Find a safe place to add and remove fuel from your vehicle. To perform1.
the calibration, you will need enough fuel to fill the tank completely and a
5-10 litre container that you can use to measure the amount of fuel being
added.
Empty all the fuel from the tank.2.
