I2M nanoLAP User manual

nanoLAP
INTRODUCTION
nanoLAP is an extremely compact infrared
transponder designed for lap times detection.
Thanks to an internal power supply (CR2032
standard battery) there is no need for a power
supply cord or any other connection with the bike.
nanoLAP can retain up to 100 laps.
nanoLAP can be mounted on seat woven by way
of a strip of high-grip Velcro (provided).
ATTENTION: make sure surfaces are clean
and grease-free before gluing.

Powering on and off
To access the battery bay, remove the rear cover
by unscrewing the fastening screws. Insert a
standard CR2032 battery and close the package.
To change battery, remove the old battery using a
small screwdriver (stored data are not lost).
To turn on the system press the button near the
download jack connector for one second. The
LED indicator will flash for a few times. When the
system is turned on, the indicator will briefly flash
once per second.
To turn off nanoLAP press the button again,
powering off will be indicated by a 1 s flashing.
When powered off, the system does not draw
current from the battery, however we advise to
remove the battery if nanoLAP is not used for long
periods of time.
Installation and operation
Infrared transponders consist of two separate
units: the transmitter, placed on pit wall with the
emitting side facing the track, and the receiver
(nanoLAP), mounted on seat woven with the
printed arrow pointing to the transmitter. nanoLAP
is fully compatible with AIM transmitters. Every
time nanoLAP receives the signal from the
transmitter the indicator stays on for the whole
duration of the signal, thus easing operational
tests.
If there is more than one transmitter on the pit
wall, we advise to keep them a few meters
from each other to prevent the signals from
overlapping and causing interferences. Even if
different transmitter operate at different
frequencies, strong signals may reduce the
receivers’ discriminating .
As a general rule, it would be best to never place
transmitters of the same kind on the pit wall. The
system allows for the setting of a Dead Time, that
is the time the receiver, after successfully
receiving a signal from a transmitter, stops
accepting any signal it detects. This could be
useful if there is more than one transmitter in the
pit lane: nanoLAP will use the first signal it detects
to record the lap times, and the other transmitters
are ignored.
Data download
To download data from nanoLAP use
HyperTerminal (Start -> All Programs ->
Accessories -> Communications ->
HyperTerminal).
Start HyperTerminal, and configure on the serial
port connected to the download cable, and set
9600 bits per second, 8 data bits, 1 stop bits,
parity None and flow control None. Choose File ->
Properties -> Settings and set Emulation to
VT100.

nanoLAP
Connect the serial cable to the PC. Insert the
communication jack into nanoLAP. Turn on
nanoLAP.
Data will be automatically downloaded to the PC.
Here we show a typical download:

Identificativo :
Tempo morto (s): 2
Sessioni: ON
Autospegnimento: OFF
Giri memorizzati: 9
Best Lap: 0:56,41
Lap 1: 1:00,49
Lap 2: 1:00,39
Lap 3: 1:03,05
Lap 4: 1:00,34
Lap 5: 0:56,90
Lap 6: 0:56,76
Lap 7: 0:56,41
Lap 8: 0:59,53
Lap 9: 0:56,31
Premere
'A' per l'autospegnimento
'C' per cancellare la memoria
'I' per modificare l'identificativo
'S' per le sessioni
'T' seguito dal valore (Sec.) per il tempo morto
After the download ends, it is possible to configure
the system.
By pressing ‘A’, “Autospegnimento“ (auto power
off) can be turned on or off (if on, nanoLAP will
power itself off after 10 minutes if it does not
receive any valid signal).
Pressing ‘I’ let you modify the “Identificativo”
(identifier) (the “name” of your nanoLAP). NB: the
identifier can be at most 8 characters.
Pressing ‘C’ will “Cancellare la memoria” (clear
the memory).
The memory can also be cleared without
connecting nanoLAP to a PC: when turning on
nanoLAP, keep the button pressed, the indicator
will flash for a few seconds and then turn off.
When the indicator will turn on again, clear will be
completed.
By pressing ‘T’ you can set the “Tempo morto”
(dead time).
Pressing ‘S’ enables or disables “Sessioni”
(sessions). When sessions are enabled, data will
be downloaded divided by session, and each
session is closed when nanoLAP is turned off.
Moreover, each session takes up additional space
in memory, corresponding to a single lap. Thus
the maximum number of laps will be smaller:
100 – number of sessions.
If the memory content is large enough to exceed
HyperTerminal window size, the visualization may
be poor. In such case we advise to use the option
Capture Text (Transfer -> Capture Text…): data
will be saved in a text file to be reviewed later in a
text editor. At the end of the download, close the
file by choosing Transfer -> Capture Text -> Stop.
We advise against the use of Notepad, since it
does not handle correctly formatted text, and data
will be difficult to review.
To download the same data again, press the
button near the jack connector.
At the end of the download and configuration,
disconnect the cable from nanoLAP. nanoLAP
will automatically power off.
When the memory if full, the indicator will signal
“memory full” by flashing rapidly (3 times per
second).
nanoLAP absorbs 3 mA, so a new battery will last
for about 60 hours.
