DASH3 Display unit

Who is the DASH3 designed for?

The DASH3 is designed primarily for competitive automotive applications. Its compact size, low weight and flexible mounting options make it a versatile tool suitable for almost all applications, from karts and motorcycles to saloon cars and formula cars. The display extends the functionality of our data loggers by allowing the user to see the data in real time in the vehicle. The DASH3lite is primarily designed to display lap times, shift lights and vehicle speed, whereas the more versatile 'full' DASH3 can be configured to display combinations of any variables from the data logger.

What does the DASH3 do?

The full DASH3 unit can be configured to monitor an array of data channels, in various formats. The graphical display type allows numerical data to be displayed in varying text heights, along with graphs and bar charts. The unit must be linked to one of our data logging devices, typically the DL1, though a number of our other products, including the DL2, SPEEDBOX, and ECU interface (to display ECU parameters only) are compatible. As standard the DASH3 comes fitted with a single 9 way d-type which takes both data and power when connected directly to a DL1. If the DASH3 is to be connected to anything else (for example a DL2 or SPEEDBOX) then please inquire with Race Technology for the correct lead.

The primary functions of both the DASH3 and DASH3lite are the lap timing and speed features. More information on the unit's comprehensive lap timing features is detailed below.

DASH3 features

Lap timing

Lap timing is one of the most important parameters for every racer. This information can be displayed in a number of ways on the DASH3lite and the full DASH3 to ensure that the most important information is presented in a clear and concise way, tailored to the user's exact preference.

There are six key lap timing parameters that the DASH3 calculates:

• Lap counter. This is a simple counter to show which lap you are on.
• Sector time. This is the time it took to complete the previous sector
• Lap time. This is the time up to that point on the current lap
• Delta sector time. This indicates how much faster or slower your last sector was compared with your best overall time for that same sector
• Delta lap time. This indicates how much faster or slower you are going compared with the same point on your best lap
• Predictive lap time. This makes a calculation - based on your current completed sectors in this lap - and displays a prediction of what your lap time will be. This prediction is based upon the assumption that you will complete all of the remaining sectors in the same time that it took you during your best lap.

Any combination of these parameters can be displayed as each lap or sector is completed, in a format that is specified using the configuration software. The unit comes pre-configured with the most common options, so that it can be used without any need for reconfiguration.

Physical mounting of the DASH3

There are 3 mounting options:

• For temporary mounting in a car there is a suction mount that can be used on the vehicle windscreen. The suction mount screws into a standard tripod mount that is also commonly found on bullet cameras, this is a 1/4" x 20 UNC thread
• For mounting in a race environment onto a flat surface we recommend using scotch lock tape onto the rear of the unit. The weight of the unit is only about 120g so in practice only a small area of scotch lock tape is required
• For permanent mounting the unit has 4 blind holes which are designed to take a 2.9mm self tapping screw (No 4) with a maximum penetration of 6.5mm

In all cases the rear of the case has been designed so that the cable can exit from the top or bottom of the unit for maximum flexibility. In race applications the exact mounting location has to be chosen carefully to maximise visibility of the screen - in particular you need to minimise reflections and have the unit at the correct angle to ensure that the full brightness of the LEDs can be seen.

Configuring the DASH3

As part of the standard Race Technology software, we supply a comprehensive configuration utility for the DASH3 which allows the user to tailor the display to meet your exact requirements. You can use the software to configure the following features:

• Which variables are displayed on the screen and where. Information can be displayed in three differently sized fonts.
• Which graphs are displayed and where
• Which bargraphs are displayed and where
• Which lap and sector timing information is displayed
• Any filtering applied to variables
• Alarm limits applied to variables
• Unit conversions - e.g. from volts to degrees Celcius, in the case of a temperature sensor
• When the shift LEDs are lit - e.g. RPM thresholds
