The CAN-Bus Hub with 7 Ports and DC Power Connection is a powerful tool designed to simplify building, testing, and troubleshooting CAN Bus networks. Featuring seven CAN ports, onboard power distribution, and optional termination control, this hub eliminates wiring clutter and ensures consistent, reliable communication between nodes.
Key Features
-
Seven CAN ports for maximum flexibility in connecting nodes.
-
External 12 VDC power input (power supply not included) for unified power distribution.
-
LED indicator for quick power status verification.
-
Built-in 120 Ohm termination resistor, easily enabled or disabled via jumper.
Advantages of Using the CAN-Bus Hub for Testing
Effortless Network Setup
The hub provides a central connection point, making it easy to assemble and reconfigure CAN networks without the tangle of multiple cables and power adapters.
Unified Power Management
By channeling external 12 VDC through the hub, you can power all connected nodes consistently from one source. This reduces complexity, saves space, and ensures steady voltage delivery across the network.
Flexible Termination Control
The built-in 120 Ohm termination resistor, switched via jumper, allows quick adjustments to match different network configurations. This flexibility is essential for accurate testing and troubleshooting.
Improved Signal Integrity
Proper termination ensures cleaner signals and prevents data errors caused by reflections or interference, providing stable communication in both development and real-world testing scenarios.
Ideal for Diagnostics
During testing, engineers can measure resistance between CAN High and CAN Low lines to confirm proper termination, isolate network sections, or identify faulty nodes—all with minimal setup effort.
Benefits at a Glance
-
Centralized node connectivity for simple, clean layouts.
-
Single-source power distribution for all devices.
-
Jumper-controlled termination for fast adjustments.
-
Out-of-the-box functionality—no software required.
-
Perfect for labs, workshops, field testing, or education.
In Summary
The 7-Port CAN-Bus Hub with DC Power Connection is more than just a hardware accessory—it’s a reliable foundation for building, testing, and maintaining CAN Bus networks. By combining power management, termination control, and easy connectivity in one unit, it provides engineers, educators, and developers with an indispensable tool for achieving smooth and efficient CAN communication.
A Comprehensible Guide to Controller Area Network
A Comprehensible Guide to Controller Area Network by Wilfried Voss represents the most thoroughly researched and complete work on CAN available in the marketplace. Controller Area Network (CAN) is a serial network technology initially designed for the automotive industry, especially European cars. Still, it has also become a popular bus in industrial automation and other applications.
The CAN bus is primarily used in embedded systems. As its name implies, it is a network technology that provides fast communication among microcontrollers up to real-time requirements, eliminating the need for the much more expensive and complex technology of Dual-Ported RAM. This book offers complete information on all CAN features and aspects combined with a high level of readability.
