Transit Case and Rack System Integration

SINGLE BOARD COMPUTERS & ACTIVE / PASSIVE BACKPLANES

I/O and PCI Express Expansion Board for the NLT and NLI System Host Boards

FEATURES

•	Two serial port connectors on the IOB31
•	On board headers for mouse and keyboard to support PS/2 keyboard and mouse operation
•	On board connectors for parallel printer and floppy ports
•	PCI Express expansion capability for backplanes such as Chassis Plans' BPX3/14

DESCRIPTION
The IOB31 is an optional I/O and PCI Express expansion board that connects to the controlled impedance connector (P20) on the NLT or NLI system host board (SHB) to complement the advanced USB and SATA I/O capability of the SHBs.

In addition, the IOB31 provides a x4 PCI Express edge connector that connects to a PCI Express expansion slot on backplanes like Chassis Plans' BPX3/14.

This PCI Express interface is designed to support additional high-speed backplane card slots while taking advantage of the increased bandwidth capabilities between the SHB and the option cards made possible by PCI Express technology.

The layout drawings below show the placement of the board's I/O and PCI Express expansion connectors. The IOB31 comes with mounting hardware and standoffs for securely attaching the IOB31 to either a NLT or NLI SHB.

NOTE:
Pin 1 on the connectors is indicated by the square pad
on the PCB.
