4.2 BT11 MDB communications connection
The connections between the BT11 banknote reader and the machine are carried out
via a MOLEX 39-01-2060 connector. (See Figure 8 .Connector´s front view). The
connections for this connector are:
N1 Colour Function
1 White Vcc (Power supply)
2 Brown Ground
3 — Not connected
4 Green Master RxD
5 Yellow Master TxD
6 Grey Common RxD/TxD
5. Maintenance procedures
5.1 Sensor calibration
Every so often to use of banknote it may be necessary to re-calibrate the sensors.
This process adjust the reading of the note to get a better acceptance
Before carrying out this process it is convenient to make a process of cleaning the
sensors and observe if the acceptance of notes improves. If it does not improve, then
proceed to the calibration of the sensors.
To do this you need a calibration note with special characteristics given by Jofemar
(Cod:2200022 to be used with the front bezel bigger than 69 mm (2.72 in) and Cod.
2200077 to be used with 67 and 69 mm (2.64 and 2.72 in) font bezels).
There are three methods to calibrate the reader:

Using the dip switches (See section 3)

Using the PC’s software for reprogramming the bill reader.

Removing and placing the stacker while the bill reader it is switched on.
Calibrating the reader by using the dip switches is explained in section 3. This method
should be used with new control cards provided by Jofemar or when the calibration by
removing the stacker does not work.
Calibrating the reader by using the PC software you have to follow the instructions
given by the software.
Calibration by removing the stacker is done following these steps.
While the reader is in normal conditions the stacker should be removed. The reader´s
red LEDs will then blink five times, indicating that there is no stacker.
Once the stacker is placed in position again the reader will verify that the stacker is on
its right position. Then and for 10 seconds the 3 central blue LEDs and the 2 red LEDs
will be on. If a calibration note is introduced during this time, the reader will proceed to
calibrate the sensors. When the calibration is done, if the reader goes back to the
normal cadence of the blue LEDs it will mean that the calibration was a success.
The calibration process is divided in two phases. The steps required are:

Introduce the calibration note.

The reader will automatically start the calibration process.

The first phase consists on a number of readings that the reader does on
the calibration note. Once is finished the note will be expelled.

All blue and red LEDs will be on indicating that the first phase is over. They
will remain on for 5 minutes or until the note is introduced again.

Once the note is introduced in the reader, the second phase will start.

In the end of the phase, the reader will expel the calibration note.
