PERATION
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.

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.

XPANDABILITY
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.
