Curtiss-Wright / ACRA Control KAD/BCU/105/D/00 Ethernet Backplane Controller Module – Conformal Coated

The Curtiss-Wright/ACRA Control KAD/BCU/105/D/00 is an Ethernet Backplane Controller Module for the KAM-500 chassis, delivering full-duplex 100BaseTX connectivity with integrated data acquisition and packet generation. Conformal coating protects against harsh operational environments. This module functions as a controller, programmer, and IPv4 packet generator—acquiring backplane data into an onboard Current Value Table, packetizing user-defined structures, and transmitting via UDP over Ethernet.

## Technical Specifications

**Ethernet Interface**
• Single 100BaseTX Ethernet channel, full-duplex operation
• Auto-sensing with auto-MDIX support

• Ethernet frame sizes: 64 bytes to 1518 bytes
• Jumbo packet support to 64 kbyte
• Multiple user-defined IENA packet structures simultaneously
• Individual programmability of packet identifiers, sizes, and destination IP addresses

**Programming and Verification**
• Program/verify mode for KAM-500 chassis hardware
• Read/write data blocks to any module within the chassis
• Ethernet-based chassis programming

**Synchronization**
• PTPv1/V2 client (KAD/BCU/105)
• External IEEE 1588-2004 Precision Time Protocol version 1 synchronization support

**Power Consumption**

**Physical**
• Mass: 75 g (2.65 oz)
• Height above chassis (bare connector): 11 mm (0.43 in)
• Conformal coated finish

## Key Features

• Full-duplex 100 Mbps Ethernet with auto-MDIX
• IPv4 packet generation with fragmentation support
• Onboard Current Value Table up to 1 megasample capacity
• UDP-based data streaming to multiple destinations
• Integrated chassis programmer for KAM-500 modules
• PTPv1/V2 client synchronization
• Low power consumption (1.55–2.07 W)

## Typical Applications

• Real-time backplane data acquisition within KAM-500 systems
• Multi-module chassis control and programming over Ethernet
• High-sample-rate data streaming via UDP unicast/multicast
• Time-synchronized data collection using PTPv1/V2

## Compatibility & Integration

Designed for integration within Curtiss-Wright ACRA Control KAM-500 backplane chassis architecture. Operates as both data controller and chassis programmer, enabling remote configuration and acquisition without local processing hardware.
