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).
