Dual Lan 3.5" SBC


What Is A Dual Lan 3.5" SBC Configuration?

Dual Lan single-board computer (SBC) is an industrial-grade SBC that is configured with two RJ45 Ethernet LAN connection ports. With Dual Lan configuration, the motherboard can improve the functionality and features of a compact single-board computer. SBCs are rugged and very compact; they can easily fit in your palm. With two full-speed GigE ports, it provides the single board computer with more bandwidth to handle multiple connections to sensors, high-resolution cameras, the internet, and other IoT devices with an ethernet connection. In this article, we will discuss the benefits of the Dual Lan SBC and the robust features of a rugged single board computer. 


4 Benefits of a Dual Lan 3.5" SBC

1. Network Redundancy


Network redundancy is a backup connectivity option in case one of the systems is failing. With Dual LAN configuration, the network redundancy for an internet connection has backup connectivity to switch the network from the first LAN input to the other LAN input automatically to avoid and mitigate the risk of downtime. Therefore, network redundancy capabilities are great for industrial applications where the computer have a backup in case one of the LAN connection failed. 


2. Higher Bandwidth


Two LAN connections equal double the bandwidth of an RJ45 LAN of 2 x 10Gbps, resulting in a whopping 20Gbps connection bandwidth. This enables the SBC to have a higher data transfer rate, which can be a significant improvement when the computer needs to transfer a large amount of data. 


3. Multiple Device Connections


With Dual LAN configuration, the single-board computer is capable of connecting various devices such as sensors, multiple cameras, or other hardware that connects to an industrial SBC. For camera configuration, the SBC can connect one cable to the internet and one LAN cable with PoE (Power over Ethernet) to the camera that provides both data transfer and power for the camera.


4. Link Aggregation


Link aggregation can be performed by a Dual LAN configuration SBC. Link aggregation or ethernet bonding utilizes both of the NIC (network interface cards) by combining them together. By grouping both LAN connections in parallel, the system can increase the bandwidth that can perform the task much faster compared to a single LAN computer’s motherboard. 


In the era of big data and machine automation, there are trillions of data constantly generated throughout IoT devices all over the world. More and more data transfer requires robust computing solutions that are capable of tackling a higher load of data transfer.

How to Utilize LAN On Your 3.5" SBC? 

1. RJ45 Gigabit Ethernet Connectivity


The RJ45 connection speed started from the oldest version of 10Mbit which is known for ethernet only, then the modern version is known as Gigabit ethernet that reaches 1Gbit and 10Gbit for the latest version. 10Gbit means the data transfer can reach 10,000Mbps through the LAN cables that are equipped with RJ45 connectors. With the fiber optic RJ45 cable, the industrial application is capable of running heavier workloads such as machine inferencing and real-time analysis.


2. PoE Capability


PoE stands for power over ethernet, which is a technology that enables the ethernet cable to transfer data between the camera and the device while supplying power for the camera to operate. Before PoE technology, a digital surveillance camera needs two connections to operate. A network connection to send data generated by the camera, and a power connection to deliver power for the camera. PoE reduces the device cables into a single cable that connecting both data and power to the device. 


3. Wake-on-LAN


Wake-on-LAN is a useful feature that enables a user to remotely power on a device that is in a shutdown, sleep, or standby mode from anywhere in the world. Wake-on-LAN is only available with a wired connection, wireless connections such as WiFi wouldn’t work. This feature is very helpful for remote applications where users are unable to turn on and run the computer on-site. 


Dual Lan Industrial Grade Single Board Computer

Dual Lan SBC is industrial grade and is capable of withstanding extreme environments such as extreme temperature, tough shock, constant vibration, dust particle, and water exposure amid deployments while maintaining its durability, reliability, and longevity. Here are some of the supporting factors that create a robust and rugged Dual LAN single board computer.   


1. Extreme temperature


Dual Lan SBC is capable of withstanding a wide range of extreme temperatures from the cold winter in the arctic sea that can reach -40℃ up to scorching hot summer in the desert that can reach up to 60℃ around the oil rig machine. Industrial single board computers temperature range is capable of reaching a freezing -40℃ up to scorching hot 85℃. These rugged industrial SBCs are capable of withstanding such heat and cold due to their innovative thermal and mechanical engineering design. 


2. Rigorous Test and Validation Process


For optimum quality and reliability, the industrial SBCs are tested and validated in a controlled reliable testing lab. The computers went through rigorous tests and validation processes to ensure the durability, reliability, and longevity of the single-board computers. These tests and specs measurements are being held in a reliable testing facility such as temperature & humidity chamber, thermal shock ramp chamber, IR thermal chamber, signal integrity tester, and electrical tester.
