Intel SBC-776 manual Parallel port connector CN14, Parallel port IRQ

Parallel port connector (CN14)

Normally, the parallel port is used to connect the board to a printer. The SBC-776 includes an onboard parallel port, accessed through CN14, a 26-pin flat-cable connector. A traditional DB-25 connector cable is needed to install the printer to the board. The cable has a 26-pin connector on one end and a DB-25 connector on the other.

Parallel port IRQ

The onboard parallel port is designated as LPT1 and can be disabled or changed to LPT2 or LPT3 in the system BIOS setup.
