Parallel port connector (CN17)

Normally, the parallel port is used to connect the board to a printer. The SBC-659P includes an onboard parallel port, accessed through CN17, 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 pin 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.
