1DL1 CLUB Introduction

The DL1 CLUB was previously known as the DL1 MK3, the two products are identical,

so any reference to DL1 MK3 equally applies to DL1 CLUB and vice versa.

1.1 What is the DL1 CLUB?

The DL1 CLUB is a completely updated version of the DL1. It is a state-of-the-art

vehicle data logging and control system. Put in the simplest terms, it stores a wide range

of vehicle data for later analysis on a computer - the system does not include an in-

vehicle display, Race Technology has a number of dashboard solutions available for the

DL1.

1.2 Who is the DL1 CLUB designed for?

The DL1 CLUB is designed for autosport applications including drag racers, single

seater racing cars, rally cars or road cars - however it is also ideal for use on power

boats, go karts and motorbikes. It is also an ideal platform for use in the auto industry

for car testing of all types, from long term monitoring to competitor benchmarking.

1.3 What does the DL1 CLUB do?

The DL1 CLUB can store data from a number of sources including its built in high

accuracy GPS and accelerometers, wheel speeds, shaft speeds, engine speeds,

temperatures, pressures, lap times, sector times etc. The DL1 comes packaged with the

excellent Race Technology data analysis package for Windows. The software allows

super accurate track mapping, user defined channels, powerful graphing and allows

direct comparison of up to 10 data sets (races) simultaneously with almost unlimited

laps. The DL1 CLUB can also be used to supply data to dashboard displays and to drive

auxiliary outputs to control fans, pumps, or lights.

1.4 Why use GPS?

One of the key features of the DL1 CLUB is its built in high accuracy GPS system - this

gives the DL1 advantages over other data loggers in 2 key areas - greatly improved

track maps and far more accurate speed data.

1.4.1 Track Mapping

Conventional data loggers require a "closed circuit" to enable them to calculate the track

map; the shape of the track is estimated from a combination of the lateral acceleration

and speed. This works adequately in some situations but it becomes increasingly

inaccurate for long tracks and impossible for open circuits, motorbikes or boats. In

contrast, the GPS will produce high accuracy track maps in almost any situation.

1.4.2 Speed Measurement

While speed is probably the most important parameter that anyone wants to measure

using the data logging system, it is also the most inaccurate in a "conventional" system.

The normal way to measure speed is to simply attach a pickup to a wheel to detect how

fast it is rotating - but the rolling circumference of a tyre changes by 4% just with wear

and temperature. Even worse, the error increases significantly under race conditions

where the tyre is under load - typically the tyre slips by up to 20% under hard braking

going into a corner. Measuring speed using GPS is now common practice in high-end

systems - under typical conditions speed error is well under 1%!

1.5 DL1 CLUB Features

The DL1 CLUB is an all-new, 3rd generation, data logger system from Race

Technology. It is a complete redesign of the DL1, retaining all the best features and

improving and adding where possible. Some of the most noteworthy features include:

•Built in GPS

The new GPS unit is based on our own high accuracy GPS3 technology and

calculates position and speed 5 times every second. This is easily the fastest, most

accurate GPS system available for under $1500. The measurements from the GPS

and accelerometers are combined to calculate very high accuracy positions and

speeds at 100 times a second. Optional storage of raw GPS data for post processing

at 20Hz is also possible.

•Built in accelerometers

Built in 3-axis accelerometer with 2g full scale (optional 6g full scale).

•Built in yaw gyro for slip angle measurement (optional)

•Logging to SD cards

Works with SD and SDHC, for up to 32GB storage.

•Up to 12 analogue inputs

The DL1 CLUB has 12 very high accuracy analogue inputs. All inputs have a

maximum of 25V input

•Up to 4 output drivers

Low side driver outputs are available for controlling pumps, fans, lights.

•2 RPM inputs

The DL1 CLUB has 2 RPM inputs, only one of which can be used at any one time.

One input is designed to be connected to "high level" sources, such as the ignition

coil. The other input is designed for low level signals such as a feed from the ECU.

•4 wheel/shaft speed inputs

The DL1 features 4 totally independent wheel/shaft speed inputs. These can be used

to measure the speed of all four wheels, or slip ratios across a torque converter for

example.

•Two RS232 ports

Either port can be used to receive data for logging, one port is always used for

outputting data for storage to a VIDEO4 or to a DASH display.

•CAN port

CAN port enable receiving and transmitting of messages at configurable rates up to

1Mbit/s

•Remote start/stop and add marker inputs

•Dual 5v reference outputs

Two independent 5v outputs can be used to drive up to 500mA each for sensor

outputs.

•Simple operation

A single button to start or stop logging, it's as simple as that! If the button is

inaccessible from the driver’s seat then a remote button and status indicator can be

added if required.

•Power supply requirements

The power supply to the DL1 CLUB data logger can be taken directly from the

vehicles 12v supply, or it can be powered from its own battery if required. The power

supply is smoothed and regulated within the DL1 CLUB ensuring its performance is

highly robust and stable.

•USB interface

USB connection for direct connection to a PC for configuration

•Testing

Very high reliability is ensured by calibrating, temperature testing and vibration

testing each unit on an individual basis. Autosport applications make tremendous

demands on electronic systems and we take great care to make sure our products are

up to the task. All the connections to the units are vibration proof, high strength to

ensure that connections do not fail at the critical time.

3Installing the unit

3.1 Mounting

As the DL1 CLUB contains accelerometers, it is important that the unit is mounted on a

flat, fairly level surface in the vehicle. A small amount of tilt can be compensated for in

the software; however, large tilt angles cause loss of resolution and increased noise due

to vertical vibration. For more instructions on compensating for accelerometer tilt, read

the following pag:.

http://www.race-technology.com/wiki/index.php/Technical/ZeroingAccelerometers

Just as importantly, the logger must be mounted "squarely" in the vehicle with the

button facing towards the back of the vehicle. If the unit is mounted at an angle to the

direction of travel for the vehicle, then the unit will be measuring longitudinal

accelerations when you are cornering and vice versa. Acceleration errors caused by

mounting the unit at an angle to the direction of travel cannot be compensated for, so it

is important to get it right.

In most installations the unit will be mounted using 2 strips of scotch lock tape on the

base of the unit. This is simple and secure and allows the unit to be moved quickly

between different vehicles. If a more permanent installation is required then there are

two main options available:

1. You can use either the mounting holes on the side of the unit. These are designed to

take 2.9mm self tapping screws (No. 4) with a maximum penetration depth of

6.5mm.

2. Or a set of "hook in" brackets are available that fit into the channels on the sides of

the case. They are made from brushed stainless steel, and are designed to be used

with M4 screws or similar diameter self tapping screws (#7 or #8). The mounting

diagram for these is shown below:

3.1.1 Bracket Mounting

3.2 Power

The DL1 CLUB Unit is supplied with a cigar lighter based power supply. The centre pin

connects to +12V and the outer connects to the vehicle ground. This method is

convenient if you are temporarily connecting the unit to the vehicle (typically on a road

car).

If you want to permanently wire the DL1 CLUB Unit directly into the engine wiring

loom, rather than using the cigarette lighter socket, then you must use a fused supply

with a fuse rating of no more than 1 amp. It is also highly recommended that the unit

has its own external power switch so it can be easily turned off. This is to prevent any

draining of the battery, or any damage to the unit when the engine is turned on or when

the car is being cranked over. It is recommended that you only turn the unit on once the

engine is running. It is possible that leaving the DL1 CLUB turned on during cranking

may corrupt the data in the logger.

Also please note that in all cases the GPS receiver is powered on whenever there is

power to the main unit - it does not turn on and off with the main unit, so if the DL1

CLUB is left connected to the battery it will flatten it.
