In addition to guns, ammunition, ruck sacs and more, the modern US soldier must now carry electronics– from night vision to radios, and now programs such as Nett Warrior add smartphones, tablets, and GPS to this load. And just like the bullets for a soldier’s gun, a soldier’s electronics need ammo in the form of batteries–and they all need to be able to communicate with themselves to share intelligence both on the field and with central command.
The Vehicular Integration for C4ISR/EW Interoperability (VICTORY) specification was developed as a standard for US Army vehicles to combat a history of the “bolt-on” approach when adding new communications systems and electronics—systems that were often siloed and had no interoperability between them. This earlier approach often led to duplicate hardware, little future-proofing and a lack of required economies for size, weight, power and costs (SWAP-C).
Ethernet is the well-established standard in government, enterprise, and home applications. It is rapidly becoming the standard for military and other rugged applications due to proven interoperability, reliability, and speed. Historically, dedicated bus architectures have been used in military applications, resulting in heavy and somewhat inflexible systems.
Ethernet has been shown as a viable alternative for a number of reasons:
- • Ethernet and IP technologies are ubiquitous
- • Ethernet devices are inherently interoperable, encouraging modularity
- • Rugged commercial off-the-shelf (COTS) components are readily available
- • Ethernet continues to receive large technology investments
- • Ethernet operates over world-spanning distances using established infrastructures
Autometrix is an industrial cutting system out of Northern California. A little over a year ago, their electrical engineer, Tyler Green contacted MilSource. Tyler was looking for a basic, board-level Fast Ethernet switch that he could integrate in to his on-board electronic package. The MILTECH 309 fit the bill. Because of its small size, ruggedized componentry and conformal coating, it could fit right in to the size and industrial shock standards needed to deliver the fast and reliable products the company is known for.

Power over Ethernet or PoE, allows a single cable to provide both data connection and electrical power to networked pieces of equipment such as sensors, IP video cameras and even wireless mesh nodes. PoE works across standard network cabling (i.e. CAT5) to supply power directly from the data ports to which networked devices are connected.
Here at MilSource, we’re happy to announce that Techaya has expanded upon it MILTECH 908MP compact Ethernet switching platform. The new MILTECH 912 is a managed Ethernet switch that offers the same advanced network features including VLANs, traffic prioritization (QoS) and bandwidth aggregation, but has expanded its port density to 12 triple-speed (10/100/1000 Mbps) Ethernet ports using 2 D-38999 connectors.
Since Techaya’s line of military-grade Ethernet switches are built from the ground up to meet the major military requirements, we are often asked to define what some of the particular specifications are that our Ethernet switches comply to. We recently discussed MIL-STD 1275 which defines the characteristics of a 28 VDC power system. Today we’re going to discuss MIL-STD-461 which is a US military standard that describes how to test equipment for electromagnetic compatibility.
Techaya’s complete line for military-grade Ethernet switches, routers and hubs are developed from the ground up to meet rigorous military standards for shock, vibration, temperature rating power requirements and other rigorous standards to ensure that a piece of equipment will hold up under the most toughest of mission, terrains and volatile situations. We often get questions as to what MIL-STD 1275 is when it comes to meeting power requirement.
MIL-STD-1275 covers the characteristics of 28-VDC (as opposed to 12 VDC) electrical systems in military vehicles and provides detailed requirements for military ground platform electrical systems, including electromagnetic compatibility (EMC), starting mode, normal operating mode, generator-only mode operation, and their associated spikes, surges and operating limits.
The Advanced Explosive Ordnance Disposal Robotic System (AEODRS) is a Navy-sponsored program for developing a new generation of open, modular robotic systems. The military services have successfully used ground robots in the fight against terror over the past decade. In addition, U.S. and international law enforcement agencies have experienced the benefit of these systems in conducting dangerous and life-threatening tasks that have saved lives throughout the world.
However, there has been a deepening of concern that the lack of interoperability between unmanned ground vehicle (UGV) systems imposes limitations on development and deployment, complicating the integration of advanced technologies and control schemes. The Advanced Explosive Ordnance Disposal Robotic System (AEODRS) is a new program sponsored by the Naval Explosive Ordnance Disposal Technology Division (NAVEODTECHDIV) and currently under test and development at John Hopkins Applied Physics Laboratory (JHUAPL).
In today’s modern warfare where survivability and mission success is dependent on data acquisition, analysis and instruction, a growing number of Ethernet-based devices supporting these missions must be connected to the central mission computer, and often to each other. Ethernet switches are needed throughout the military infrastructure as a common means of making such connections. We often get the question from customers on whether they need a managed switch or an unmanaged switch. So, today, we’re going to talk about the basic capabilities of each.
