MyChron Light TG, the new AIM lap timer, is the evolution of the well known MyChron
Light MCL. This new logger merges all functionalities and good qualities of its forefather
with the new graphic display and adds a lot of other useful functions, like the visualisation
of sampled data as histograms and the different working and sampling modes.
MyChron Light TG reduced dimensions, moreover, makes it easy to install and use in any
situation without problems.
MyChron Light TG is available in two versions: internally and externally powered.
Internally powered thanks to the batteries supplied with the kit, can be used Plug&Play
both fixing it with a simple strip of Velcro®, to be easy displaced and installing it more
steadily through the four anti-vibration mounting placed back on the logger. In both cases it
is sufficient to switch MyChron Light TG on, configure it and its starts sampling.
Externally powered on the contrary, it is to be connected to an external 7-15 V power
source and automatic switch off after 20 minutes of inactivity avoids undesired battery
exhaustion.

1Chapter 2 – Installation and powering
MyChron Light TG installation depends on the version.
102.1 – MyChron Light TG with internal power
To install MyChron Light TG internally powered stick a strip of bi-adhesive Velcro®on the
product rear. This way the logger can be used on more vehicles. It is also possible to use
the four anti-vibration mounting placed back on the logger. This last installation needs a
flat surface and 4 Silent Block not included in the kit.
MyChron Light TG is powered by two 3 Volts round batteries type CR 2430 included in
the infrared receiver. To change the batteries see the chapter concerning MyChron Light
TG maintenance.
112.2 – MyChron Light TG with external power
MyChron Light TG with external power can be installed exactly as the one internally
powered except for the fact that it needs an external power source connection (the vehicle
battery).
This MyChron Light TG version has two cables out coming from the logger bottom:
connect the red cable to the battery positive pole and the black one to the negative pole.

212.3 – How to install and power the infrared receiver
The lap receiver is connected to the logger through a cable. It has to “see” the transmitter
installed on the side of the track. Install it with the eye, highlighted here below, looking to
the transmitter.
Ensure that the receiver has a straight line towards the transmitter on the right side of the
vehicle. The receiver is powered like the system.
122.4 – The lap transmitter: installation, powering, working mode
AIM produces and sells two kind of transmitters: the lap transmitter (image below on the
left) and the split transmitter (below on the right). The two devices emits different signals
and MyChron Light TG can distinguish and manage them.
Both can be internally or externally powered:
•internally: with 8 AA batteries (placed in the transmitter case); when the batteries
are flat power led starts blinking each second (1 Hz);
•externally: with an external 12V power cable; when the battery is flat the led starts
blinking each second.
The transmitter has two working mode:
•low power mode: for circuits less than 10m (30 ft) wide;
•high power mode: for circuit more than 10m (30 ft) wide; in this second case an
external 12V power source is needed and both led switches on when the transmitter
is powered on.

www.aim-sportline.com
To enable high/low power mode it is necessary to open the transmitter case as shown
here below on the left.
Images here above on the right shows the different working options. The transmitter
comes set on low power mode: images top on the right. To set high power mode insert
both clips in the jumper: image bottom on the right.
It is suggested to check the number of transmitter installed on the circuit before
installing one’s own. It is in fact possible that transmitters additional to the one
placed on the start/finish line are installed on the track. The simplest way to record
correct lap times is to use the same transmitter(s) for all drivers.
Use obscuring time function (paragraph 3.2) to be sure that MyChron Light TG reads only
the desired transmitter(s).
132.5 – How to change MyChron Light TG batteries
MyChron Light TG batteries are inserted in the receiver case. To change them unscrew
the four screws that fasten the two parts of the case and change the batteries.
MyChron Light TG uses two 3V round batteries code CR2430. The code is generally
stamped on the batteries.

2Chapter 3 – MyChron Light TG quick configuration
MyChron Light TG needs to be configured. Here follows explanation of the steps to be
performed for a quick configuration. Other configuration options are deepened after. Here
below is MyChron Light TG keyboard. Functions associated are shown by the display in
correspondence to each button.
Pressing twice “1” MyChron Light TG main menu, shown here below is activated.
143.1 – Track name
From the main menu select “Track”. The related menu is shown here below.
The track name to be set can be chosen among these stored (“Select”) or inserting a new
one (“Enter names”). In both cases the system enters available tracks list, shown here
below on the left (in case no tracks are stored all names are set on “NONAME #X”).
If the track is stored in the logger memory (“Select”) just select it, if not (“Enter Names”)
place the slider on an empty position (or the system overwrites the one stored) and press
“OK”. “Enter track name” page opens. Once the name composed press “OK”. The system
asks for confirmation, press “Yes”. The system can store up to 50 circuits.

223.2 – Session mode
From the main menu select “Session mode”. The related menu is shown here below.
Available options are:
•Lap Counter: the lap timer is set as lap counter;
•Qualify: fill in the session duration in minutes (range from 5 to 60);
•Race: fill in the “race distance” to say the number of laps (range from 3 to 2000).
233.3 – Obscuring time
Obscuring time is a time period during which the lap receiver installed on the vehicle, after
having stored a lap signal is “blind” (does not record signals). This function is to be used to
manage split times on circuits where more optical transmitter are set: to record split times
set obscuring time on a low value; not to record split times set obscuring time on a value
lower than best lap time and higher than the time elapsed between the last split and
start/finish line. Accepted range is: 3-180.
From the main menu select “Obscuring Time”. Its menu is shown here below.
Use “DEC-“ and “INC+” to set obscuring time and press “OK”.

243.4 – Split times visualisation
From the main menu select “Configuration”. The related page is shown here below.
Select “Split”. The related under menu shows all possible split visualisation modes.
MyChron Light TG offers eight different split visualisation modes:
•None: records splits but do not show them;
•Elapsed Vs...: see paragraph 3.4.1;
•Section Vs...: see paragraph 3.4.1;
•+/- Previous: compares actual split time with the same split of the previous lap and
shows the gap top right on the display;
•Actual: shows the actual split central on the display;
•Accumulative: shows the time elapsed from start/finish line central on the display;
•Running lap time: shows running lap time top right on the display.
283.4.1 – Elapsed Vs. and SectionVs. mode
The two “Vs” modes compares two times.
In both cases an under menu opens: it is possible to compare lap time with the best lap in
the session or with the best lap recorded on that track (Vs Best Lap in memor...). In this
second case it is necessary to have previously set the track.

266.1 – What is “Best Rolling” and “Theoretical best”
Lap
Number Lap Time Time Start/Finish line-Split 1 Time Split 1-Split 2 Time Split 2- Start/Finish line
1 1’23” 30” 18” 35”
2 1’22” 28” 20” 34”
3 1’21” 26” 19” 36”
“Theoretical best” (1”18’) is the lap time obtained summing up the best session split
times. It’s called theoretical because it adds non consecutive splits belonging to different
laps. In the table the best theoretical comes adding:
•Lap 3 Start/Finish line-Split 1: 26”
•Lap 1 Split 1-Split 2: 18”
•Lap 2 Split 2- Start/Finish line: 34”
•Theoretical best: 1’18”
“Best Rolling” (1’19”) is the lap time obtained adding the best consecutives split times
really recorded. It’s a “rolling” time because is not calculated within one only lap but is
based on the fact that these best splits are consecutives. In the table above the theoretical
best comes adding:
•Lap 3 Start/Finish line-Split 1’26”
•Lap 3 Split 1-Split 2: 19”
•Lap 2 Split 2-Start/Finish line: 34”
•Best Rolling: 1’19”
