Racetime 2 - OptoJump Program User manual 3

1Introduction

The Optojump program for Racetime functions along the same lines as the Optojump program for

PC, with which it is totally compatible, in this sense, that it allows the transference of data acquired

with Racetime 2 to the personal computer for subsequent elaboration and storage of the data.

2Connecting the OptoJump system

Make sure that the Optojump modules are correctly aligned, as indicated in the Optojump system

assembly instructions. Connect the cable coming from the interface/battery for Optojump to the

socket located at the rear of the Racetime 2 chronometer using the appropriate 9 pole/15 pole

adaptor. Now the system is ready to function.

3Switching on Racetime 2, initialization

Switch on Racetime 2 with the switch located on the back of

the device. The display will show several items of information

about the software version installed on your Racetime 2, and

the serial number of the device.

If you have to contact Microgate for any information or about

any problems, always give the serial number of your system.

Press a key to continue.

At this point the following screen displays may appear:

Check to see if the device was completely emptied after the

previous work session. Any previously memorised data has

been irretrievably lost. Press ENTER to continue.

Check to see if any anomalies were discovered during initial

tests on the machine. Contact Microgate for further

information.

Usually appears after switching on. Press F3 to delete

previously memorized data (your choice must be confirmed).

Should you have canceled the memorized data, if your

Racetime 2 chronometer is equipped with other timing

programs (in addition to the Optojump management

program), you can select the function mode.

To select the Optojump program, first press F4 (other) to pass

to the second screen display.

Now press F3 (C: Optojump) to enter Optojump mode.

These operations are not necessary if your Racetime 2 is

equipped with only the Optojump program.

If the data memory has not been canceled or the Optojump

mode was chosen in the previous work session, you can set

configuration parameters automatically on standard values,

namely:

•Automatic printout on confirmation of test: deactivated

•Average value calculation mode: on all values

•Number of WalkJump modules: 6

•WalkJump start mode: manual

•WalkJump timeout: 0s (deactivated)

•WalkJump step minimum length: 41cm

•WalkJump direction: entrance from interface side

•WalkJump automatic acquisition: deactivated

•OptoJump test start: from inside measurement base

The meaning of each parameter will be clear when you have

become familiar with the different types of test, which are

described in the following pages.

4Main menu

After choosing the OptoJump program on the chronometer

(see chapter 3 - choosing the program is obviously not

necessary if your Racetime 2 is equipped with only the

OptoJump program), you enter the main menu, from which it

is possible to access all the available functions.

F1 – New tests – To enter the menu for the selection of the

tests to be performed (chap. 5)

F2 – Tests done – To access the menu for the display of

previously memorized tests (chap. 6)

F3 – Data transmission – Activates the transmission of

memorized data to the PC. Connect the PC to Racetime 2 with

the appropriate cable (Cod.CAB046 or Cod.CAB047 +

Cod.CAB001), and press F1 (Start) to confirm the start of

transmission. The memorized data is transmitted according to

the protocol given in the Appendix. For reception, we

recommend you use the OptoJump program on PC (versions

3.20 and subsequent). In this way the transferred data will be

stored and can be viewed as if it had been acquired directly

with the Personal Computer.

F1 – Synchronization – Allows you to synchronize Racetime

2’s internal clock. This function should be used when you

employ two or more Racetime 2 systems in WalkJump mode

with automatic acquisition. See chap. 5.10 for further

information.

F3 – Automatic printout: Yes/No – Select ‘Yes’ if you want

the tests performed to be printed automatically after they have

been confirmed. Modify your choice (Yes/No) by pressing F3

repeatedly.

Set the exact time and confirm with F3 (OK). To correct the

setting, press F2 (Edit).

Press START or activate the START input to synchronize the

internal clock.

F2 – WalkJump test base – This functions allows you to

verify the correct alignment of the OptoJump bars when two

or more modules have been connected to each other for the

acquisition of contact and flight times and of step lengths

during a run (WalkJump test).

After selecting the test, press F2 (Test), as indicated on the

display, to begin the test itself.

Press F1 (Nmod) to set the number of modules present on the

track.

ATTENTION: for correct functioning of the test, it is

essential that the number of modules set on Racetime 2

corresponds exactly to the number actually present on the

measurement base.

Select F3 (menu) to return to the main menu.

The alignment test checks the measurement base for about 10

seconds (during this time the message ‘Please wait’ is shown).

This time is normally enough to signal inaccurate alignments

which cause '‘intermittent'’ interruptions at some points of the

base, and which therefore may escape detection by ‘visual’

control (green ‘SIGNAL’ led on all the modules).

After data acquisition, the points at which an interruption has

been detected are displayed. Each module includes 32

sensors, numbered from 1 to 32. Module 1 and sensor 1 are

considered to be those which are near the connection cable

between modules TX and modules RX. To view the next

interrupted sensor, press F1 (Next). Press F4 (esc) to return to

the main menu.

If on the other hand alignment is perfect, a message of

confirmation is displayed.

F1 : Averages : all values/minimum and maximum excluded

– If ‘all values’ is chosen, the average values of the

measurements acquired (flight times, contact times, etc.) are

calculated on the basis of all the values acquired during the

single test.

If on the other hand ‘excl. min/max’ is chosen, the values for

the jumps in which the minimum and maximum flight time

has been measured will be excluded.

Note: the exclusion of the minimum and maximum values

occurs only if at least two jumps with flight and contact times

different from zero exist, i.e. if at least two jumps starting

from inside the measurement base have been made or three

jumps if the jumps are made outside the measurement base.

To modify your choice, press F1 repeatedly.

F2 : Key beep : on/off. Select ‘off’ to deactivate beep

emission when the keys are pressed.

To modify your choice, press F2 repeatedly.

To return to the first screen display of the main menu, press

F1 – Preconfigured tests

Enables you to choose tests in which the mode of operation is

predefined; it is therefore not necessary to specify the number

of jumps to be made, the duration of the test or the start mode

from inside or outside the measurement area.

Below you will find a list of the acquisition modes of the

preconfigured tests. Many tests have the same acquisition

sequences. They are dealt with separately so as to distinguish

between the various tests according to the different body

movements (arms free/arms at sides, etc.) involved in each

one.

Squatjump, CMJ (Countermovement), CMJ FA

(Countermovement arms free), Technical test:

3 jumps starting from inside the measurement area

Stiffness, stiffness FA (arms free): 7 jumps starting from

outside the measurement area

Jump time 15, 30, 60s : test with predefined duration of 15,

30, 60s, starting from inside the measurement area.

After selecting the type of test you wish to perform, you will

see the number of the athlete and the number of the test for

the trial you will carry out.

(Important: the combination athlete’s code/number of test is a

single item, which means that Racetime 2 does not allow the

same athlete to perform two tests indicated by the same test

number).

To modify the athlete’s and/or the test number, press F2

(Edit.). Press F3 (Impos) to modify the test settings (see

following paragraph).
