Curtiss-Wright Parvus DuraDBH-672 Introduction
MNL-0661-01 Rev A1 ECO-N/A Effective: 25 January 2016 Page 7 of 34
FUNCTIONALDESCRIPTION
The DuraDBH-672 Digital Beachhead™ is a rugged Commercial Off the Shelf (COTS) multi-function system
integrating a Gigabit Ethernet (GbE) switch and quad-core vetronics processor capable of supporting VICTORY
services and mounted Assured-Position Navigation Timing (A-PNT) capabilities in a MIL-STD-qualified small
form-factor chassis. The DuraDBH-672 builds on and extends many of Curtiss-Wright’s original DBH-670 Digital
Beachhead capabilities but in a lower Size, Weight, Power and Cost (SWaP-C) design capable of consolidating
network switch, vehicle processor, embedded GPS, atomic clock, inertial navigation, solid-state storage, and
add-in I/O interface all in a single Line Replaceable Unit (LRU). Featuring 16 ports of fully managed Layer 2
GbE switching/static Layer 3 routing together with a low-power, multi-core ARM-based i.MX6-Quad processor,
the DuraDBH-672 system supports not only general-purpose embedded computing/in-vehicle edge networking
requirements, but can also serve as a VICTORY Infrastructure Switch and Shared Processing Unit for the In-
Vehicle Network (IVN) Architecture adopted by the U.S. Army/US Marine Corps’ Vehicle Integration for
C4ISR/EW Interoperability (VICTORY) initiative. With optionally integrated Assured Position, Navigation and
Timing (A-PNT) components, including a military SASSM/M-Code GB-GRAM (Ground Based GPS Receiver
Application Module), a Chip Scale Atomic Clock (CSAC), and Inertial Measurement Unit (IMU), this highly-
capable system can enable cost-effective, accurate Mounted Assured-PNT (MAPS) functionality and affordable
PNT hub capabilities using non-GPS augmentation for mounted platforms.
Combining proven, high Technology Readiness Level (TRL) COTS subassemblies and open architecture
technologies into a single multi-function solution, this next-generation Digital Beachhead delivers a powerful
set of standard and optionally integrated capabilities. The unit’s carrier-grade network management software
provides a powerful feature set for multicast traffic, VLAN, port control, Quality of Service (QoS), Link
Aggregation, SNMP management, secure authentication, redundancy, precision timing (IEEE-1588 PTPv2), and
data zeroization. It’s multi-core processor provides a robust set of vetronics I/O interfaces (USB, GbE, RS-422,
RS-232, CANbus, DIO, HDMI) along with a modular I/O and storage architecture based Mini-PCIe cards and
mSATA SSD Flash storage modules to support application-specific I/O requirements (i.e. MIL-STD-1553 /
ARINC429 / COM / DIO modules). Application engineering services are available for modified COTS (MCOTS)
configurations at minimal/no NRE cost, including pre-integration of Mini-PCIe I/O cards. Tested to meet harsh
MIL-STD-810G and MIL-STD-461F requirements, the unit boasts fanless operation over a wide operating
temperature range (-40 to +71°C) and tolerance to extreme shock/vibration conditions, high altitude, and
humidity, making it suitable for technology refresh and new platform deployments, including mobile, tactical,
aerospace, and ground vehicle applications. It features front-panel MIL-DTL-38999 circular connectors in a
sealed IP67 (dust/ water proof) aluminum chassis together with industrial temperature grade components, EMI
filtering, and isolated MIL-STD-1275/704 power supply that protects against vehicle/aircraft voltage surges,
spikes and transients.

2016
HARDWAREOVERVIEW
SYSTEMBLOCKDIAGRAMS
The block diagram in Figure 1 illustrates typical use case device interfaces for the DuraDBH-672. Using
the integrated processor and the 16 port gigabit Ethernet switch the DuraDBH-672 is intended to integrate
all the vehicle systems and provide consolidated, real time, data to vehicle operators. It provides
integrated CAN bus interfaces to monitor vehicle health as well as RS232/422/485 serial interfaces for
legacy equipment. It can then convert and migrate these interfaces to Ethernet to communicate with
more modern military equipment. The HDMI interface provides a convenient way to monitor all the
vehicle electronics connected to the DuraDBH-672.

Curtiss-Wright Parvus DuraDBH-672 Hardware Overview
MNL-0661-01 Rev A1 ECO-N/A Effective: 25 January 2016 Page 13 of 34
THEORYOFOPERATION
The DuraDBH-672 consists of two main subsystems. The processor subsystem consists of a quad-core
ARM Cortex A9 running at 800MHz. This provides standard user interfaces such as USB, HDMI, serial
ports, CANbus, and optionally audio input and output. The processor natively runs a Linux operating
system and optional VICTORY software as well as any other user applications that may be required.
Another key feature is the mini-PCIe and mSATA expansion capability. Customers can select any COTS
or custom mini-PCIe card allowing a broad array of interfaces and features. Anything from video capture
and CODEC cards, analog IO, or specialized DSP/FPGA based cards.
Figure 2 DuraDBH-672 system architecture block diagram
The second subsystem consists of 16-port gigabit Ethernet switch. The processor subsystem and
Ethernet subsystem are connected together via an internal Ethernet port. This fully managed Layer 2
Gigabit switch provides a powerful set of carrier-grade networking features, including support for IPv4 and
IPv6 multicast traffic, Virtual Local Area Networks (VLANs), port control (speed / mode / statistics, flow
control), Quality of Service (QoS) traffic prioritization, Link Aggregation (802.3ad), SNMPv1/v2/v3
management, secure authentication (802.1X, ACLs, Web/CLI), redundancy (RSTP/MSTP), precision
timing (IEEE-1588v2), port monitoring, IGMP Snooping, Built in Test (BIT), and data zeroization. The unit
also supports Layer 3 IPv4 unicast static routing for IP routing to attached WAN / radio ports.
MODULARITYANDEXPANDABILITY
The DuraDBH-672 provides a powerful and flexible platform to integrate a variety of devices based on
mini PCIe form factor. The DuraDBH-672 supports two (2) miniPCIe sockets that can be used for a
variety of additional functionality and/or IO without increasing the size of the unit.
The product also supports an expansion slot for mSATA SSDs and SAASM GPS modules. The figure
below shows the expansion capability of the main circuit board.

You can test the DuraDBH-672 interfaces and cabling prior to installation in the target system to ensure
full operational capability. Full bench-top testing can be performed by using an appropriate cable set for
this system. CBL-DBH672-4B is available for purchase from Parvus to support lab or bench testing
purposes. You can also create a custom set of cables made specifically for the intended target system,
vehicle, or craft; refer to Chapter on Connector Descriptions for connector pinouts and descriptions.

MANAGEMENTANDSOFTWAREINTERFACEOVERVIEW
The DuraDBH-672 provides independent console access to the CPU and Ethernet subsystem typically for
development and debug purposes. In addition, both subsystems are accessible via Ethernet. A software

CPUMANAGEMENTINTERFACEDESCRIPTION
On the Early Access units, the CPU root account has no password. You will need to connect to the CPU
via the RS232 port using TeraTerm or similar terminal program and assign a root password. The terminal
interface should be configured at 115200 baud rate with no flow control. See figure below.

Once a root password has been assigned you can connect to the Ethernet port via SSH. Due to security
consideration all other remote services (including network services such as FTP, TFTP, etc) are not
enabled.
SWITCHMANAGEMENTINTERFACEDESCRIPTION
The DuraDBH-672 management interfaces provide the network administrator with a set of comprehensive
management functions. The network administrator has a choice of two easy-to-use management
interfaces:
Serial CLI (command line interface)
Manages all switch features, including CLI enhancements.
Must be used to change the switch IP address from the factory default.
Can be used even if there is no network connectivity.
Provides brief help on syntax for each command.
Web GUI (graphical user interface)
Manages all switch features except the switch IP address and CLI enhancements.
Requires network connectivity.
Provides extensive help on functions and parameters
SERIALCLISETUP
1. Connect the DuraDBH-672 Switch serial management port to a serial port on the host PC.
2. Power-on the DuraDBH-672.
3. Open a terminal emulator on the host PC, such as TeraTerm or PuTTY on Windows, or Minicom on
Linux.
4. In the PC terminal emulation software, configure the serial port to 115200 baud, 8 data bits, 1 stop bit,
no parity, no flow control.
