Interfaces

 

 

Bidirectional parallel interface The bidirectional parallel interface offers the so called “nibble” mode of the IEEE1284 interface norm. This enables installation in accordance with Win 95 “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 trans- mission in blocks of 1 KB.
