This manual is conceived to be user friendly, more graphical and easy to understand.
In the first secon are described the electrical connecons, the ways to fix and lead the taximeter,
how to assemble the sensor box.
The second secon explain the meter’s operave modes, the funcons and the programming
phase (Autotest, Stascal Memory, “Trip by Trip” buffer and the Tariffprogramming).
The third secons contains the descripon of all the tariffprogramming parameters.

Test Connector
The Test Connector for M1 MDT taximeter is a mini USB connector that must be inserted in its
dedicated slot as shown in this draw. Please use this slot only to connect the test connector cable.
Any other device with the same plug must not be connected as it can damage the device.
NOTE: In order to use with property the test connector funconality blue wire must be connected to a power baery
suply with almost 12v. Once the test connector is powered and plugged in the M1 MDT slot, the main display will
show “teston”.
If the text “teston” doesn’t appear in the M1 MDT main display even with the test connector plugged in, please
review the blue wire connecon.

“E-Seal”- Electronic Sealing:
1st Secon: Last 100 Reading Changes Done
The “E-Seal” is a non-erasable memory splied in two secons where, in the first secon, are recorded the last 100
alteraons made on the programming funcons. These are shown on the displays or printed, with detailed informa-
on of: index nr, event, date, year and hour. The second secon is made of permanent, non-reseable, progressive
individual events counter, incremented by each event alteraons without details. The first secon is by default a FIFO
buffer, with the last 100 events recorded, but can be configured by tariffto disable the FIFO and block the taximeter
when it reaches its maximum capacity. The second secons (counters) is never FIFO, and when reaches its maximum
capacity of 1000 events on any counter, the taximeter shows “ESEAL FULL” and it is blocked unl the mechanical seal
is broken and the taximeter is again inialized.
The “E-Seal” Reading, is included in the “SelfFunon Menu”. This is the procedure to enter it:
1) Keep pressed K2 at least for two seconds to enter in the menu selecon
2) Select E-Seal menu by pressing K2 key
3) Comfirm by K4 the E-Seal reading.
Now the first Record is showed on the display (see figure 1). To increase the record index press K4; to decrease the
record index press K3. The following pictures are only an example of E-Seal records because every single device could
have a different records sequence.

For Hire - Hired - Stopped
The Operave Mode
The taximeter works with 3 working modes:
In any of these modes it is possible to have different funcons acvated by pressing one of the 5 taximeter’s buons:
In FOR HIRE posion the follow sequence
can be obtained by pressing the OP buon:

• The main display (3) is turned off
• The right one (5) shows the clock.
Once the taxi starts the trip, the Taxi Driver selects the
Hired posion by pressing OP buon.

The right ones the added extras (5).
The current tariffcan be changed by pressing the key K1 if
manual tariffchange is available
At the end of the trip, the Taxi Driver has to select the
Stopped posion to calculate the final fare.
He does it by pressing the OP buon. The waing me is
thus blocked.

Pre-Selecon of the Tariff
In order to avoid possible fraudulent use of the taximeter, it is possible to acvate an alternave way of starng a
trip, that allows to select the desired tariffwhen the taximeter is sll in For Hire posion, and so to start the trip
directly with the pre-selected tariff.
Tariffpre-selecon is acvated by changing the following setup quesons:
Q32=yes
Q2=0
Q3=number of tariffs
When Pre-Selecon is enabled:
pressing K1 key from “For Hire” posion is shown the
TariffSelecon menu, and the driver has to select the
tariffnumber.
To start with scrolling through the tariffs with K3 (up)
and K2 (down).
The selected tariffis confirmed by pressing K1 key again,
and so the taximeter starts the trips directly with the
Pre-selected tariff.
If the tariffis not selected in 5 seconds, the taximeter
goes back to “For Hire” posion

The K-Constant
(Car Transmission Rao)
The “K Constant” is the number of pulses per Kilometer emied by a transducer and received by a taximeter.
K Constant = Pulses/Kilometer
The pulses can be emied by the car’s electronic transducer or, if the car is not provide of it, by the Digitax mechanical
one or by a third part interface. This constant can be known or be tested on road.
How to find out the K-Constant value (Autotest)
Follow this procedure to find out the car tansmission rao (K-constant).
For a right procedure it must be done in a road with a carefully marked distance of 1 Kilometer(default).
Align carefully the car’s front wheels with the test distance‘s start line.
Take out the taximeter programming cover
Select For Hire posion.
Insert the Service Programming Key (1) in its slot.
Press K2 and K3 buons at the same me.

Start driving at 30 km / hours maximum.
Drive to the Autotest Finishing Point (1 Km).
Once the Autotest Finishing Point is reached, press K4 buon to finish the
Autotest. Now the taximeter will calculate and record the new K- Constant.
The main display (5) will show the new K-Constant value. The secondary
display (5) will show the number of pulses generated during the Autotest.
