Parallel Interface Board
The IC U2, ATMEGA16 (microcontroller), is responsible for the communication between the
printer and the computer. The IC U3, 74LVC/LCX125 is a buffer and also functions as a level
adapter, making the voltage conversion in some signals (5V to 3.3V).
The recognition of the interface connected to the control board is done with the reading of a
code associated to each kind of board through U1, enabled by the SELDEV signal generated by
the control board.
In this interface there are still two CN2 connectors (5x2 pin bar), which are used to the
programming of the microcontroller and CN3 (5x2 pin bar), reserved.
