Hello, fellow forum members! I’m the technical support specialist for the SV910. Recently, I’ve noticed many discussions about vehicle gateway technologies, so today I’d like to give you a detailed breakdown of our product’s technical features. As a front-line technical support engineer, I’ll do my best to explain these points in the simplest terms possible. If you have any questions, feel free to ask at any time.

M12 Connectors: An Essential for Automotive Environments

Let’s start with the M12 connector. Anyone working in automotive knows how demanding the requirements for connectors can be. With operating temperatures ranging from -35°C to +75°C, constant vibration and shocks, and exposure to moisture and corrosion, traditional RJ45 connectors simply can’t withstand these conditions. The SV910 is equipped with two M12 aviation-grade Ethernet ports, designed primarily for reliability. The threaded locking mechanism of the M12 connector effectively prevents loosening due to vibration, and its IP67 protection rating ensures resilience in harsh environments. From a technical perspective, this design offers a significant reliability upgrade over standard RJ45 connectors.

Memory Expansion: The Foundation for Edge Computing

In terms of hardware, the SV910 vehicle gateway comes standard with 2GB of RAM, expandable to 4GB, and 8GB of eMMC storage, expandable to 16GB. This is considered a high configuration among vehicle gateways. Why so much memory? Automotive applications are becoming increasingly complex, especially those involving edge computing. Real-time image processing, sensor data fusion, and AI algorithm execution all require substantial memory resources. 2GB of RAM is sufficient for most scenarios, while 4GB provides even greater headroom.

eSIM Technology: The Advantage of Remote Management

The eSIM feature is extremely practical, especially for autonomous driving scenarios. The SV910 supports two eSIM cards, allowing remote management of SIM activation and switching. The greatest technical advantage of eSIM is its remote programmability. Traditional physical SIM cards require manual replacement, which is costly and inconvenient in unmanned environments like mines or ports. With eSIM, SIM profiles can be managed over-the-air (OTA), greatly reducing maintenance complexity and cost.

Dual 5G Architecture: Achieving Network Redundancy

This is one of the SV910’s core technical highlights. It supports dual-mode configurations, allowing for either dual 5G or a combination of 5G + 4G/RedCap modules. The main value of dual 5G lies in network redundancy and bandwidth aggregation. If one 5G network fails, the system can automatically switch to the other, ensuring continuous communication. Under optimal network conditions, bandwidth aggregation can be achieved to boost data transmission efficiency. This design is especially valuable in scenarios with stringent network reliability requirements, such as autonomous driving and remote monitoring.

V2X Communication: Dedicated Short-Range Communication Technology

V2X is a differentiating feature of the SV910 vehicle gateway. Technically, the device provides two V2X antenna interfaces and supports standard V2X communication protocols. V2X technology is based on the IEEE 802.11p standard, operating in the 5.9GHz band, and supports vehicle-to-vehicle (V2V) communication. The main value of this technology is its low latency and high reliability, with typical latency under 10ms—crucial for safety-critical applications.

Automotive Ethernet: Core Technical Analysis

Now for the highlight: the SV910’s automotive Ethernet interfaces. It is equipped with three 1000/100BASE-T1 ports and three 100BASE-T1 ports—a configuration rarely seen in the industry. Here are the technical details: BASE-T1 is the standard for automotive Ethernet. Compared to traditional BASE-T interfaces, its main advantages are:

• Single twisted pair transmission, reducing cable weight and volume
• Longer transmission distances: 100BASE-T1 supports up to 15 meters, 1000BASE-T1 up to 15–40 meters
• Superior EMC performance, suitable for automotive electromagnetic environments

TSN Support

The SV910 supports PTP (Precision Time Protocol), which is the foundation of TSN (Time-Sensitive Networking). PTP enables microsecond-level time synchronization across the network, which is critical for real-time control applications.

VLAN Support

VLAN technology is supported, allowing the creation of multiple logical networks on a single physical network. This enables traffic isolation for different applications, enhancing both network security and Quality of Service (QoS).

Additional Technical Features

• Power Management: Supports a wide DC input range (9–48V), with built-in reverse polarity, overvoltage, and overcurrent protection—essential for automotive environments.
• ESD Protection: Ethernet ports feature 1.5kV ESD protection; RS232/RS485 ports have 15kV ESD protection; SIM card interfaces also have 15kV ESD protection. These measures are vital for automotive reliability.
• Interface Configuration: In addition to Ethernet, the SV910 offers one RS232, one RS485, two CAN interfaces (expandable to three), two relay outputs, and two digital inputs—covering most common automotive application needs.

Software Features

The software suite is comprehensive:

• Multi-link Management: Supports link aggregation and load balancing
• Routing Protocols: Supports static routing, OSPF, and RIP
• VPN: Supports IPsec, OpenVPN, L2TP, PPTP, VXLAN, and GRE
• Data Acquisition: Supports MODBUS and Siemens S7 PLC data acquisition
• Cloud Management: Supports remote configuration, remote upgrades, and FOTA (Firmware Over-The-Air) updates

Technical Summary

From a technical standpoint, the SV910 is highly optimized for automotive environments:

• M12 connectors enhance connection reliability
• Dual 5G architecture ensures network redundancy
• The number and specification of automotive Ethernet ports are top-tier—six automotive Ethernet ports are rare among similar products
• V2X functionality adds a unique competitive edge
• Comprehensive protection measures and wide temperature range design ensure robust operation in harsh conditions

Core Advantages

• Interface Richness: Six automotive Ethernet ports plus two M12 connectors—an industry-leading configuration
• Reliability: From connectors to power supply, from ESD protection to wide temperature range, every aspect is designed for stable operation
• Network Redundancy: Dual 5G architecture guarantees communication continuity for mission-critical applications
• Forward-Looking Technology: Support for V2X and TSN positions the SV910 for future intelligent driving applications

Application Scenarios

The SV910 is especially suitable for scenarios with extremely high network reliability requirements, such as:

• Autonomous vehicles (especially in closed environments like mines and ports)
• Domain controllers for intelligent connected vehicles
• In-vehicle edge computing platforms
• Mobile command vehicles requiring multiple network connections

Final Thoughts

Overall, this product offers significant technical advantages in the vehicle gateway sector, particularly in automotive Ethernet and network redundancy. If you have specific technical questions—such as interface configuration, network topology design, or software feature setup—feel free to discuss with me anytime. One final reminder: while the SV910 is feature-rich, selection should always be based on your specific application scenario. If you only need simple data transmission, so many automotive Ethernet ports might be overkill. But if you’re building a vehicle backbone network, this configuration is extremely valuable.
