Parallel Interface (Optional); Connector Assignment - Tally Dascom LA2810 User Manual

Interfaces

Parallel interface (optional)

The bidirectional parallel interface offers the so called "nibble" mode of the
IEEE1284 interface norm. This enables installation in accordance 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.
