1. Product Overview
The TES‑1080‑M12 is an industrial-grade unmanaged Ethernet switch designed by ORing Industrial Networking Corp. It belongs to the TES‑1080‑M12 Series, a product line engineered specifically for harsh‑environment and mobility‑focused applications such as rolling stock, transportation systems, railway vehicles, onboard vehicle networks, and industrial mobile platforms. The product’s article number is TES‑1080‑M12, and it represents the standard model within the series that includes both the TES‑1080‑M12 and the TES‑1080‑M12‑BP2 variant. The device is engineered for full EN50155 compliance, ensuring suitability for railway and transportation equipment and guaranteeing mechanical, climatic, EMC, and electrical resilience. It is designed as a compact, rugged IP40‑rated metal‑enclosed switch featuring eight 10/100Base‑T(X) Ethernet interfaces using vibration‑resistant M12 D‑coded connectors.

2. Key Features
The TES‑1080‑M12 Series provides a robust unmanaged switching solution with reliable data transport over M12‑based Ethernet links. Key technical attributes include full EN50155 railway certification, IP40 metal enclosure, shock‑resistant M12 connectors, and wide‑temperature tolerance from ‑40°C to +70°C. The switch supports auto‑negotiation, auto‑MDI/MDI‑X, store‑and‑forward switching, and IEEE 802.3/802.3u/802.3x standards for 10/100 Mbps Ethernet and flow control. Additional features include a warning system with relay output for power failure indication, LED indicators for link/activity and duplex/collision, as well as triple power LEDs and a fault LED. The BP2 variant includes dual hardware bypass pairs for Ethernet redundancy across power interruptions. The switch supports redundant 12–48 VDC power input through a 5‑pin M23 connector, ensuring operational continuity. Designed for rolling stock, it withstands vibration, free fall, shock, and EMC disturbances per IEC and EN standards.

3. Technical Specifications
Dimensions are 125 mm width, 65 mm depth, and 196 mm height, equivalent to 4.92 × 2.56 × 7.72 inches. Weight is listed as 854 g for the main model and 872 g for the BP2 version, providing a rugged but transport‑compatible hardware footprint. The enclosure is metal with an IP40 rating, providing dust protection. The switch incorporates eight 10/100Base‑T(X) Ethernet ports implemented using 4‑pin M12 D‑coding connectors, ensuring mechanical locking, dust protection, and shock resistance. The relay output uses a 5‑pin M12 A‑coding connector with normally‑closed (N.C.) contact and 3 A at 24 VDC capacity. Input power is dual 12 to 48 VDC with reverse polarity protection and overload current protection. Typical power consumption is 5 W for the standard TES‑1080‑M12 model. Operating temperature ranges from -40°C to +70°C, and storage temperature spans -40°C to +85°C, with operating humidity between 5% and 95% non‑condensing. The MAC table supports up to 8192 addresses, and the processing method is store‑and‑forward.

4. Functionality
The device provides unmanaged Layer‑2 Ethernet switching for industrial and transport applications. Each of the eight M12 10/100Base‑T(X) ports supports auto‑negotiation for 10/100 Mbps and half/full‑duplex operation, plus automatic MDI/MDI‑X detection for simplified cabling. Flow control based on IEEE 802.3x ensures frame integrity and reduced packet loss under heavy traffic. The switch is designed for high‑vibration environments such as trains, trams, metro systems, buses, or other mobile industrial equipment. The M12 connectors secure cable connections under shock, vibration, and continuous movement. Use cases include Ethernet backbone connections inside rolling stock cars, inter‑carriage coupler networks, on‑vehicle surveillance systems, passenger information systems, and redundant onboard control networks. Compatibility includes any IEEE 802.3/802.3u compliant Ethernet devices such as IP cameras, HMIs, PLCs, controllers, and onboard data acquisition systems.

5. Components and Accessories
The standard package includes the TES‑1080‑M12 unmanaged 8‑port EN50155 Ethernet switch and a Quick Installation Guide (QIG). The BP2 variant package includes the TES‑1080‑M12‑BP2 model, featuring 8×10/100Base‑T(X) ports and 2×bypass pairs, also supplied with a QIG. Connectors include 4‑pin M12 D‑coded Ethernet ports, 5‑pin M23 power input connector, and a 5‑pin M12 A‑coded relay output port. The product supports optional DIN‑rail installation or wall mounting. The switch’s physical interfaces include LEDs for power, fault, link/activity, and duplex/collision. While cellular and RF antenna interfaces are mentioned in the general Transporter series description, these are not part of the TES‑1080‑M12 model configuration and therefore are not included.

6. Installation and Setup
The device is designed for wall mounting and supports a straightforward installation process as described in the quick installation guide. It can also be mounted onto DIN rails where compatible brackets are available. Installation requires connecting dual 12–48 VDC power inputs via the 5‑pin M23 connector to ensure redundancy. M12 Ethernet cables must be inserted into the D‑coded 4‑pin connectors and securely tightened to maintain shock‑resistant connectivity. For systems requiring alarm signaling, the relay output can be wired to external monitoring equipment. Ventilation is passive and depends on ambient airflow due to the fanless architecture. The switch operates automatically without configuration, as it is completely unmanaged. Once mounted, powered, and cabled, the system begins functioning immediately with no software setup.

7. Performance and Capabilities
The switch delivers reliable 10/100 Mbps Ethernet performance. Store‑and‑forward switching minimizes transmission errors by checking packet integrity through frame CRC before forwarding. The MAC table, supporting up to 8192 entries, ensures efficient forwarding in networks with many devices. Flow control aids in congestion management. The BP2 model adds two bypass sets, which allow P1–P2 and P3–P4 to maintain connectivity even during power loss, providing network survivability essential in rolling stock and transport systems. Power consumption is approximately 5 W, enabling efficient operation even in power‑constrained environments. Its rugged construction enables continuous performance under shock, vibration, and temperature extremes. The device is limited to unmanaged switching, meaning it does not support VLANs, QoS configuration, SNMP, or other advanced management functions.

8. Standards and Compliance
The TES‑1080‑M12 Series meets major railway and industrial standards, primarily EN50155, governing electronic equipment used on rolling stock. This includes compliance with EN50121‑3‑2, EN55011, and EN50121‑4 EMC requirements. EMI compliance is met according to FCC Part 15, CISPR/EN55022 Class A. EMS immunity aligns with EN61000‑4‑2 ESD, EN61000‑4‑3 RS, EN61000‑4‑4 EFT, EN61000‑4‑5 surge, EN61000‑4‑6 CS, EN61000‑4‑8 magnetic field, and EN61000‑4‑11 voltage dips. Mechanical robustness meets IEC60068‑2‑27 shock, IEC60068‑2‑6 vibration, and IEC60068‑2‑32 free fall. Safety compliance conforms to EN60950‑1. The device’s IP40 enclosure rating assures protection from solid particles in industrial environments.

9. Additional Information
ORing Industrial Networking Corp. provides a 5‑year warranty for the TES‑1080‑M12 Series, reflecting confidence in reliability for long‑term industrial operation. Maintenance requirements are minimal due to the fanless, solid‑state design, with no moving parts. Support is available via telephone, fax, email, and the ORing website. Documentation, such as the Quick Installation Guide, provides guidance for rapid setup. Since the switch is unmanaged, no firmware updates or configuration software are needed.
