There are two positions on the MMC where jumpers can be placed. They are
called Jumper 1 and Jumper 2. (Square IC with 44 pins)
A change in the jumper setting does only have effect during system boot.

The default communication settings in the MINIMECH
TM
are a baudrate of
4800 BPS and even parity. If a different setting is required it should be
changed with item 115 and 116 described in chapter 6.2.
If Jumper1
is open during system boot, the system will always run with default
values. (4800 BPS and Even parity)
If jumper1
is closed during system boot, the system runs with values set with
item 115 and 116.

Jumper 2 is used to clear the part of the non-volatile memory in the
MINIMECH
TM
which keeps the length and thickness data of the notes currently
known by the machine.
When the note-data is cleared, the machine will enter Learning-notes mode.
This mode is indicated on the three LEDs on the MMC machine controller. All
three LEDs are flashing together in parallel at a frequency at about 3 Hz.
When the MINIMECH
TM
has entered the Learning-notes mode, the machine is
ready to learn new note length and thickness in a Learning-note sequence
described in chapter 2.4.
When the status of Jumper 2 is
changed before a system boot, the machine
will clear the note data during boot and enter Learning-notes mode.
The meaning of change is: If Jumper 2 was
closed at the time for the last
boot, it should be open for the next boot of the MINIMECH
TM
. And if Jumper 2
was open at the time for the last boot, it should be closed for the next boot of
the machine.
NOTE! It is also possible to enter the Learning-notes mode by a software
command. The software command is WD/392/0 and is described in chapter
4.4 under the command Write Data.
