Note

For maximum reliability, keep the cable between the board and the device it drives to 10 feet or less in length.

IEEE-1284-compliant Cables

Using the parallel port for high-speed data transfer in ECP/EPP modes requires special cabling for maximum reliability.

Some of the parameters for a compliant IEEE-1284 cable assembly include: All signals are twisted pair with a signal and ground return

Each signal and ground return should have a characteristic unbalanced impedance of 62 +/- 6 ohms within a frequency band of 4 to 16MHz

The wire-to-wire crosstalk should be no greater than 10%

Please refer to the IEEE-1284 standard for the complete list of requirements for a compliant cable assembly, including recommended connectors
