INTRODUCTION

North Atlantic Industries’ (NAI) Sensor Interface Unit (SIU33) is a rugged base-plate conduction-cooled that takes advantage of NAI’s rugged conduction-cooled 3U cPCI multi-function I/O boards and power supply product architecture. The SIU33 provides a high density, compact data distribution system solution for I/O intensive and/or processing applications. The SIU33 supports full I/O control and communication over Ethernet. MIL-STD-1553, ARINC 429/575, Serial or CANBus interfaces are also available as primary interfaces when the boards are configured as such. PowerPC, Intel® Core™-i7, Intel ATOM™ or ARM Single Board Computer (SBC) processors can be added for a complete processing and I/O solution. The SIU33 is designed to support up to three NAI multi-function pre-configurable I/O boards, with or without processing, that support a wide variety of interface and communications function modules, all fitted/housed in a single rugged multi-board slot SIU system chassis, which is “delivered” pre-integrated and fully tested as a system.

Note

Since initial release of the SIU33 product line, the SIU33 housing was updated to include support for VPX (VITA 46) & OpenVPX (VITA 65) architecture SBC & I/O boards. The SIU33 can be configured to support VPX architecture for certain/select applications as/if applicable. Primary reference to cPCI will remain throughout this manual, but it is noted that certain details which may be specific to VPX are not highlighted in this general manual.

OBJECTIVES

This manual provides the user with basic hardware implementation and information regarding the operation and interface of the SIU33. Each SIU33 is fitted with either one to three 3U OpenVPX boards and a AC or DC power supply unit. Additional PSU option for “hold-up” power/time is available.

SCOPE

This manual only covers the operation of the SIU33 as a stand-alone I/O subsystem. This manual does not cover specific details relating to the operation of the specific I/O boards and function modules fitted within the SIU33. Please reference the board specific documentation for details regarding the board level configuration(s).

I/O Connectors (J1 to J3) and SLOT Designations

Connectors J1 to J3 route all the I/O from the three cPCI boards within the SIU33. The I/O pins from the cPCI Slot-X_P2 connectors of the cPCI cards are routed through the backplane to the SIU33 front panel connector. The I/O pin-out information for the J1 to J3 is defined by the configuration of the cPCI boards and function modules fitted to the cPCI boards.

Note

The SIU33 was originally introduced as a cPCI board support system. It has since evolved in supporting VPX board configurations. For configurations supporting VPX boards, the J3 I/O connector is replaced with a 128-pin 25-35F sell/insert B-key connector. References to follow or currently for the cPCI board support systems only. Please contact the factory for additional details supporting VPX board configurations if/as applicable.

Basic Operations

The SIU33 is delivered as a tested unit. All pins and operation have been verified. It is recommended that Power and Ethernet connections be made to verify operation of the boards fitted within the SIU33 by making use of NAI’s Embedded Soft Panel based GUI sample application that can be utilized as a board level “exercising” tool (if the SIU33 card configuration supports). The example process below describes the use of NAI’s Ethernet communications software tool.

After applying appropriate power to the SIU33, connect a host computer (laptop or similar running Windows or Linux), to the appropriate Ethernet enabled/configured board (configured/populated in slot 1) Port A or Port B. The selection of Ethernet Port A or B is dependent on Slot-1 cPCI board configuration.

Note

Ethernet port assignments, MAC address, and factory default IP address are indicated on the chassis label

Pin-Out / General System Functions

J3-25PS-ON/OFF#
J3-26SYSTEM GND
J3-17cPCI-SYSRST#

PS-ON/OFF#

Logic level open or “High” (+5V) (referenced to Input Power Return of the SIU33) enables power output of the internal PSU effectively applying power to the SLOT-1 and SLOT-3 I/O cards.]

Logic level low (GND) (referenced to Input Power Return of the SIU33), disables power output of the internal PSU effectively removing power from (shutting off) SLOT-1 and SLOT-3 I/O cards.

SYSRST#

Logic level GND (referenced to internal system GND of the SIU33) initiates/applies active low assertion to the cPCI SYSRST# signal on the cards; once released, will effectively introduce a ‘system/card’ reset.

Note

SYSRST# function is dependent on slot 1 card type/configuration; if slot 1 card is a “controller” type card (e.g. 75PPC1 or 75G5 w/ ARM capability, then SYSRST# is routed to the “push-button” reset input of the card, and the card issues the RSTn signal on the backplane to all other “slave” cards within the chassis when SYSRST# is asserted. If the slot 1 card is a “master” type card only (e.g. 75G5-master, etc.), then the SYSRST# signal is hardwired to all cards within the chassis (all cards will have RSTn applied simultaneously).
