OVERVIEW AND FEATURES:- The SPA MICRO-DASH is a small steering wheel or bulkhead mounted display that connects to a control (CPU) box via a flexible coiled lead. Two small steering wheel mounted switches connect to the display to provide display scrolling and menu functions. The dash comes complete with sensors for speed, pressure, temperature, and lap times (system 2) and can be configured for all types of analog sensors and is fully customizable. The dash is upgradeable by software, and already contains 4Mb memory for future data logging system upgrades. Here are some features of the SPA LAPTIMER system:- 8 analog channels (9 including brake bias) for pressures, temperatures etc. Easy to read compact LCD display with variable brightness backlight. 3-stage high brightness shift lamp tree built in to display (blue, green, red). Display shows, RPM, speed, odometer mileage/lap times, analog channels EG pressure, temp. Buttons scroll the bottom of the display for showing all analog channels. Display options for showing combinations of current lap, previous lap, best lap, or compare lap. Performance indicator on lap times shows large up/down arrows and time difference as you drive. Computer download option of lap times with Windows based analysis software. Easy menu selection for customizing display and units. Under and over programmable alarms flash on display and (optionally) external led lamps. Tell tale maximums for all channels stored.

After the SPA Micro-Dash has been switched on, wait a couple of seconds for the display to initialize (SPA DASH disappears). If any under or over alarms or activated, the letters are flashed on the LCD to show which channel has activated the alarm (it may be necessary to scroll the display if you are using more than 2 channels). Also the under or over (or both) external alarm lamps (if fitted) are flashed. For example if oil pressure is shown as OP on the display, then if the oil pressure drops below the low pressure alarm set point OP will flash on the display and the external under alarm lamp will flash. GENERAL SETUP NOTES:- TACHOMETER To setup the tacho, simply select the number of cylinders your engine uses. For certain types of ignition systems, that is ones that have more than one ignition coil per engine, it will be necessary to set the cylinders to a different number than the engine has. If you are using a tacho output from the ignition amplifier box, some systems (like the Ford coil less) give half the ignition pulses and so cylinders would be set to 2. Also most motorcycles use an ignition coil per pair of cylinders, so a 4 cylinder engine would need to be set to 2 on the tachometer since it will only see half the number of ignition pulses. Normally the filter is set to ON, but if you are using a special CDI ignition you may have to select it to OFF as the ignition pulses are very short, although this is very rare. SPEEDOMETER Since the whole accuracy of the speedo hinges in the accuracy of the circumference data (factory default is 1800mm) it is important to set it up correctly. It is possible to "Trim" the speedo to take into account external errors and to cater for differential ratios when measuring from prop shafts. PLEASE NOTE: If the speedo is not calibrated and the sensor not set correctly, the speedo may record incorrect distance on the odometer. Correct operation is important since the odometer cannot be reset. Measure the tyre at the centre of the tread and enter this value using the menu system. The trigger points are usually set to one (factory default setting) for a single magnet. PRESSURE The factory default for pressure is OIL, this is shown by the letter symbol OP on the display. Also pressure units are set by default to PSI, and the low pressure warning is set to 25PSI. All theses can be changed if desired, IE the letter symbol, the units, and the low pressure set point. If you wish to change these, please refer to the Display and menu system section. TEMPERATURE The factory default for temperature is WATER, this is shown by the letter symbol WT on the display. Also temperature units are set by default to Degrees C, and the over temperature warning is set to 105. All theses can be changed if desired, IE the letter symbol, the units, and the over temperature set point. If you wish to change these, please refer to the Display and menu system section. EXAMPLE To set the temperature to show OT instead of WT :- Water temperature is on channel 2, you can easily tell what channel it is on by the order of the item on the LCD display, left is channel 1 and extreme right (scrolled across) is channel 8. Hold down the left button while you press the right button to access the menu system. On the display you will see recl, click the left button until you reach AnLg. (This is a sub menu system) press and hold down the left button. After 2 seconds, the display will show channel 1. Since the temperature channel we want to change is channel 2, click to change to channel 2. Now leave the button for 4 seconds and the display will change to type. This is the first of many sub menus. Click until the display changes to LEt1 Use this to change the first letter from W to O. Press and hold down the left button. After 2 seconds, the current letters W will be displayed in the right hand analog display. Single click to increment up, or press and hold again for 2 seconds and the letter/numbers will count up quickly. Keep going past Z, it will go through (space) and (minus) and numbers 0-9, A, B and on up to O. Now leave the button for 4 seconds to return to the sub menu LEt1.Click on to the next menu item to store the data and the job is done. Now you can either return to the AnLg menu by clicking through the sub menus until you return to it, or exit the menu system by holding down the left button while you press the right button. 4

To return to the sub menu, leave the button for 4 seconds. If you single click again, you will return to the AnLg menu item. End of sub menu section NOTES: 1) Brake Bias. To display brake bias you must set up the channels in the order Front brake, Rear brake. EG channel 3= Front brake, channel 4 = Rear brake. When you do this there will be an extra channel showing bias percentage front and rear when you click the right button scroll the display to the right after rear brake (pressure). 2) none. Always set the unused channels to none, but do not have any channels in between used channels set to none. Always keep unused channels on the end EG channels 1-5 in use, 6-8 set to none. offp Use this to zero pressure sensors and custom channels, and view the voltage output of any sensor. It will read the offset value, and store it in the offs sub menu shown above. Press and hold down the left button. After 2 seconds, the display will change to ---- and the offset will be read and stored. Wait for the display to return to offp. Note: Although you can use this function to view the output voltage of any sensor, you are only allowed to zero pressure channels, and custom channels. Non-pressure (except custom) channels will display NA (not applicable) if you try to zero them. trig Press and hold down the left button. After 2 seconds, the current trigger points setting will be displayed. Single click to increment the trigger points up, or press and hold again for 2 seconds and the trigger points will count up quickly. When the number reaches 99 it will go back to 1. To return to the menu, leave the button for 4 seconds. CirC This routine is used to enter the rolling circumference of the tyre being used. Since the whole accuracy of the speedo hinges in the accuracy of this data it is important to learn how to use it. It can also be used to "Trim" the speedo to take into account external errors and to cater for differential ratio's when measuring from prop shafts. PLEASE NOTE: If the speedo is not calibrated and the sensor not set correctly, the speedo may record incorrect distance on the odometer. Correct operation is important since the odometer cannot be reset. 1) General calibration procedure:- Measure the exact circumference of the tyre at its centre. This circumference is now entered in two parts, Centimetres and Millimetres. Press and hold down the left button, after 2 seconds the current circumference will be displayed in millimeters and then it will show CM. To change the number, press the red button momentarily to increment it 1cm (10mm) at a time, or press and hold and the display will count up quickly. When the display reaches 4000 it will scroll back round to 0100. When this has been set correctly, release the button. After 4 seconds the display will change to MM. To change the number, press the red button momentarily to increment it one at a time, or press and hold and the display will count up quickly. When the display reaches XX99 it will roll over to XX00 and the centimeters (XX) will increase by 1. To exit the routine, release the button for more than 4 seconds and it will return to the menu. 2) Special calibration:- If you require to trigger off a target with 10 teeth, then set the trigger points number to 10 in the Trigg points menu. If the target is running at wheel RPM then simply enter the tyre circumference as described above. However if the target is driving a differential, then using a calculator, divide the circumference of the tyre by the ratio of the differential, and enter this value as the circumference, as described at the beginning of this section. If you require to trim the accuracy of the speedo because for example the differential ratio is not accurately known, and you have determined that the speedo is reading say 2% high, then using a calculator, subtract 2% off the currently stored circumference value and enter this new value as described in the at the beginning of this section. The speedo will then read 2% lower than previously. 12

test Press and hold down the left button. After 2 seconds, the display will show ----. Rotate the wheel so that the south pole of the magnet activates the sensor. When the sensor is activated, the display will show 0000 and the red LED will light on the CPU box. Rotate the wheel further, when the sensor is not activated, the display will show ---- and the red LED will go out on the CPU box. This is useful as a functional check of the speedo sensor, and for testing if you have the correct magnet polarity and sensor gap. Cyl Press and hold down the left button. After 2 seconds, the current cylinders setting will be displayed. Single click to increment the cylinders up, or press and hold again for 2 seconds and the cylinders will count up quickly. When the number reaches 16 it will go back to 1. To return to the menu, leave the button for 4 seconds. F on (FILTER ON/OFF):- Press and hold down the left button, after 2 seconds the display changes to the desired option. Normally this is set to ON, but if you are using CDI ignition you may have to select it to OFF as the ignition pulses are very short. ShF1, 2,3: - This routine is used to enter the shift points for the engine being used. When the engine RPM exceeds this shift point number, then the appropriate lamp will light. These are:- ShF1 - blue led ShF2 - green led ShF3 - red led (very bright) Press and hold down the red button, after 2 seconds the current shift point will be displayed in x1000 RPM. To change the number, press the red button momentarily to count it up 10 RPM (0.01 x1000 rpm) at a time, or press and hold and the display will count up quickly. When the display shows 19.99 it will scroll back round to 00.01 To exit the routine, release the button for more than 4 seconds and it will return to the menu. Replay laps Press and hold down the left button. After 2 seconds, laptime for lap 1 session 1 will be displayed. Single click to view one lap at a time, or press and hold (for 2 seconds) to fast forward through the laps. If you reach the end of a session, the session will increment up (if there is one) and show lap times from lap 1 in that session etc. When you have reached the last lap in memory (IE the last lap on the last session) the display will return to lap 1, session 1. When you wish to exit Replay laps, leave the button for 4 seconds and the menu will return. ntse This also shows the current session in use. If you wish to start a new one, press and hold down the red button. After 2 seconds the next new session number will be displayed. After selecting Next session, the fastest lap stored in memory will be reset, ready for a new one in the new session. Sessions never change until you use this option, your laps will continue to increment up until you select ntse. dele Warning all data will be lost after using this option. Make sure you have downloaded, or recorded the data you need to keep before using this option, it cannot be reversed. Press and hold down the left button. After 2 seconds, the display will show Sessions deleted. All the memory is now free to use, and fastest times are reset. dloa Connect the Laptimer to the serial port (comm. port) on the PC using the Laptimer download cable. Start the Laptimer software on the PC. If you have not set-up the serial port for your computer in Laptimer, use the online help to guide you through it. You must complete this before you carry on below. Press and hold down the red button. After 2 seconds, the display will show read Now press the Get data button on the Laptimer software (see online help for further details). The display should now change to SEnd, and after a few seconds data will be uploaded to the host PC. Note that if only a small amount of data is to be sent, you may not see the SEnd message due to the speed it flashes. If there is a problem with received data in any way, the PC will retry to upload it. When you have finished downloading, press the red button again to return to the menu. Chan Press and hold down the left button. After 2 seconds, the current transmitter beacon channel to pickup from will be displayed. Any number of cars may share the same transmitter beacon and channel number. 13

Single click to increment the channel number, or press and hold again for 2 seconds and the channel number will count up quickly. When the number reaches 99 it will go back to 1. To return to the menu, leave the button for 4 seconds. Car If you have a remote laptimer option fitted to the car, use this to set a unique identification number for that car. If the remote laptimer matches this number (and the channel number), then it will accept the data from the car and display and store it. This enables any number of laptimers to be used together in the same paddocks without interfering with each other. Any number of remote laptimers may pick up an individual car number, so they can be set to pick out separate cars. To change the number, press and hold down the left button. After 2 seconds, the current car number for the remote laptimer to pickup from will be displayed. Single click to increment the car number, or press and hold again for 2 seconds and the car number will count up quickly. When the number reaches 255 it will go back to 1. To return to the menu, leave the button for 4 seconds. retr This sets the time that the laptimer ignores further signals from the transmitter beacon, after it has received one. This is to prevent false triggering. It is normally not at all critical, and nominally set to 2 secs, but it maybe useful on very small (EG Kart) tracks, if there is any danger the transmitter beacon being received on two parts of the circuit. Under ideal conditions the transmitter beacon can reach as far as 60 Metres, so this needs to be borne in mind when setting up the transmitter beacon. To change the retrigger time, Press and hold down the left button. After 2 seconds, the current Retrigg time (in seconds) will be displayed. Single click to increment the Retrigg time, or press and hold again for 2 seconds and the Retrigg time will count up quickly. When the number reaches 60 it will go back to 1. EG Set the Retrigg time to 4 seconds, after the car passes the transmitter beacon, it will ignore (not retrigger) from any further signals for 4 seconds. Sig Press and hold down the left button. After 2 seconds, the display will show Bd=00 and Gd=00. If the receiver detects any infra red pulse that is not correct or corrupt, you will see the Bad number count up, and the Good number return to zero. If the receiver detects any infra red pulse that is correct and on the selected channel, you will see the Good number count up, and the Bad number return to zero. This is useful as a functional check, and for testing out the range of the system, and the effect of nearby transmitter beacons. To return to the menu, click the button. Lin1 Press and hold down the left button. After 2 seconds, the display will show the current selection for the top line. These are in sequence CUrr, CoMP. Single click to change the current selection. If CUrr lap option is selected, then the display continuously shows the current running lap time line 1. This is shown by the CURR symbol on the display. If CoMP lap option is selected, then the display continuously shows the lap time difference between a previous lap at the same position in the track and the current lap time on line 2. This time difference is also indicated by the UP and DOWN arrows on the top right of the LCD display. This mode is shown by then DIFF icon on the display. Lin2 Press and hold down the left button. After 2 seconds, the display will show the current selection for the bottom line. These are in sequence FAStest lap, LASt lap. Single click to change the current selection. If FAStest lap option is selected, then the display continuously shows the fastest recorded lap in the current session on line 2. This is shown by the FST symbol on the display. If LASt lap option is selected, then the display continuously shows the last recorded lap on line 2. CoMP Press and hold down the left button. After 2 seconds, the display will show the current selection the lap comparator (lap performance indicator). These are in sequence FAStest lap, LASt lap and reference lap. Single click to change the current selection. If FAStest lap option is selected, then the lap performance indicator uses lap data stored from the fastest lap to compare to the present lap and indicates up or down as you drive. If LASt lap option is selected, then the lap performance indicator uses lap data stored from the previous lap to compare to the present lap and indicates up or down as you drive. If reference lap option is selected, then the lap performance indicator uses lap data stored from a manually selected reference lap to compare to the present lap and indicates up or down as you drive. When in this mode, the present lap is compared with the previous lap until the left menu button is pressed. When the button is 14

pressed, the last lap data is kept, and on the following laps is used to compare up and down as you drive. The button can be pressed as many times as desired to create a new reference lap. This lap is held in memory even with the power off, until the button is pressed again, or a different CoMP mode is set. 15

INSTALLATION NOTES DO'S & DON'TS :- DO'S DO ensure that the CPU box is protected if it is likely to get any water spray on it. The connectors however are not water proof. DO ensure that the channel cables and laptimer receiver cable is not run next to any power cables, especially cables carrying switching current EG ignition coil feeds. Try to run cables next to the chassis. DONT'S DO NOT allow cables to run through sharp edged apertures without protection. DO NOT fix the cables next to or onto any surface likely to exceed 80 degrees Centigrade. RECEIVER TUBE INSTALLATION, DO'S & DON'TS :- DO'S DO ensure that the tube is pointing straight across the track. The receiver tube should be horizontal or angled slightly down (0-15 degrees) DONT'S Do not obscure the line of sight of the receiver tube to the transmitter. Glass is OK but nothing else. 16

LAPTIMER SETUP (SYSTEM 2) The menu system can be accessed at any time except during lap timing. After a lap beacon is passed, the menu system is locked out until the dash is switched off and back on again. Also the odometer information will not reappear until the dash is switched off and back on again as it will be used to display lap time information. SETTING THE TRANSMITTER:- The trackside transmitter beacon should be mounted approx 1 metre above the ground, ideally on a tripod as this allows more accurate alignment. Aim the transmitter so that the beam is shining directly across the track horizontally, do not angle the transmitter up or down. To select the transmitter channel to use, hold down the black button as you connect the 12v battery. You can now single press the button to increment up the channels, or press and hold down the button, and after 2 seconds the channels will count up quickly. When the channel reaches 99 it will roll over to 1. When you have selected the transmitter channel, disconnect the 12v battery and then re-connect it after a few seconds. The channel number is now stored in the transmitter You do not need to do this every time you use it, once the channel is set, it will stay there permanently until you wish to change it again. After the battery is connected again (without the button being pressed), the button is disabled so that the transmitter cannot be accidentally moved to another channel. The transmitter consumes 0.25A from a 12v battery, so a well charged battery is essential for a days testing. A 6Ah battery should give around 24 hours continuous use. If the battery voltage falls below 11v, then the transmitter will flash LB to indicate Low Battery. The transmitter is completely water proof, however the battery connections should be covered or protected with silicone grease, or the battery mounted in a water proof box.. The transmitter should not be placed too close to another transmitter, especially another SPA one, as the beams may overlap and interfere with each other. Try to put at least 2 metres between them, although this is not so critical at short distances. The beam is spread over a +/- 20 degree angle. Also, try to keep the transmitter beacon higher than the highest part of a car to avoid blocking of the infra red signal. OPERATIONAL NOTES When the car first passes the transmitter beacon, the laptimer display start showing your current lap and lap time (or time difference). After that, every time the car passes the beacon, the display may show current lap or time difference (lap comparator) on line 1 of the display, and last lap or fastest lap on line 2 of the display. The way the display shows these is set with the menu system. LAP COMPARATOR If you this is a new session and you have set Lin1 (line 1) to show CoMP (compare lap), then line1 (and the up down arrows) will be blank for the first lap, as there is no data to compare with. On all laps after that the up and down arrows will show increase or decrease as you drive, and show the difference in time. If you have set CoMP for FASt (fastest lap) and a new fastest lap is achieved, then this lap data will be used to compare on the following laps. If have set CoMP to show LASt (last lap) then the last lap data will be used to compare on current lap. If have set CoMP to show ref (reference lap) then the last lap data will be used to compare on current lap until the left button is pressed (holddown for 0.5 sec or more) the last lap data will then be stored and used to compare on the following laps. The button can be pressed again on a future lap if a new reference lap is desired. If you have the remote pitwall laptimer option fitted, then the laptime data is also transmitted via the radio transmitter box. The same data that the driver sees is then received on the remote laptimer unit. After the race, the laptimes can be viewed on the display unit, or all lap sessions in memory downloaded to a PC, 17

for viewing, storing and printing in a traditional LAP TIME SHEET format. It is a good idea to use the Sig (signal test) menu option to test the laptimer before race testing. If there is very bright sun, very low in the sky, there may be a possibility of the infra red receiver being blinded (the sun is a very powerful source of infra red), if this is the case, try angling the sensor down toward the road a few degrees (but less that 20 degrees). Alternatively fit a sun hood over the receiver tube. However the system has been tested under these conditions and still worked well without any external sunhood. Once you are racing, if you come into the pits after say lap 5, then laptime will continue to count up. If you continue racing, your pit stop time will be included in your lap 5 time. However, if you switch the Microdash off in the pits, it will not store any data for lap 5 as it was never finished. When you switch the Microdash back on again, it will start on lap 5 again, but from scratch. This means that you will have to pass the transmitter beacon to start lap 5 timing again. If you wish to restart from lap 1 on the laptimer again, you need to select ntse (next session) from the menu system. In this case, the Fastest lap time will be reset. The laptimer can store a maximum of 2000 laps. The maximum number of sessions allowed is 999 but only the 99 digits are displayed. The more sessions you use, the less lap memory is available. Also only 999 laps can be used per session. Wet weather use You can use the laptimer option in wet weather. The receiver tube and its connectors are sealed to IP68, and the transmitter is water proof. However please bear in mind the following:- The range of the laptimer will be reduced by rain dampening effect, water droplets on the transmitter LED lenses, and water / mud on the receiver tube. Try to keep them as clean as possible. TRACK SETUP DIAGRAM 18
