Parallel interface The bidirectional parallel interface offers the so called “nibble” mode
of the IEEE1284 interface norm. This enables installation in accor-
dance with Windows “Plug & Play”.
The standard parallel interface is able to transfer data at a speed of
max. 30,000 bytes per second. When the receiving buffer is full, the
data input is blocked until the data buffer is empty. This guarantees
data transmission in blocks of 1 KB.
