Interface Connectors

This chapter contains the following sections:

Interface Connectors Overview

The Main Board and the Expansion Board each have two connectors that provide power and interface connections to external devices and to each other. All of the connectors belong to the SEARAY® Connector Series from SAMTEC. Depending on the mating connector selected by the integrator, the connector series supports a stacking height from 7 mm to 18mm (not all increments are supported).

Main Board Interface Connectors (I/O and Network Interface)

The locations and designations of the two Main Board interface connectors are shown in the following figure.

The Main Board I/O connectors (J1 and J2) are a SAMTEC SEAF-40-05.0-S-06-2-A-K 240-pin connector. See the following figure for the pin numbering convention.

Board to Board Connectors

Both the Main Board and the Expansion Board use the SEARAY® Connector Series from SAMTEC. Depending on the mating connector selected by the integrator, a stacking height from 7 mm to 18mm (not all increments are supported). Table 8 lists the board connectors and the mating connector options that are available to achieve specific stacking heights below (The Main and Expansion Boards use the -05.0 SEAF Lead Style shown in the following table.
