Chat with a live Product Specialist! A Serial Hub connects devices with USB, RS232, RS422, or RS485 serial interfaces to a local area network for transmission of serial data over wired or wireless Ethernet. The most common application for a Serial Hub is out-of-band management of routers, switches, and firewalls as an efficient way to recover equipment when the network is down. With a physical wired or wireless (LTE or WiFi) Ethernet network connection on one side, and one or more serial ports on the other side, Serial Hubs are designed to operate as if you are locally connected to the serial port with a direct cable connection. This is perfect in M2M communication where client access needs to be made independent of any operating system or proprietary protocol. While some Serial Hubs are very simple devices, it is best practice to use one with advanced security functionality, data encryption, and user authentication to ensure network data transmissions, and access to network equipment is protected.

Serial hubs support many different serial communication protocols including RS232, RS422, and RS485. Users can connect hubs in serial to expand a network and provide easy connectivity for plugging in other devices. Hubs plug into serial ports on the computer and provide four or more ports for peripherals. Serial hubs can be used in many different applications. Serial hubs can be designed for versatile support of applications in industrial automation, process control, manufacturing, and across a broad range of commercial operations including retail POS, hospitality, back office, medical, and security systems. Serial hubs may be designed to operate at different speeds; older standards such as RS232 and RS485 networks may be limited to slower speeds, while newer standards like USB serial devices may be able to operate at much higher speeds. Serial hubs expand serial ports to multiple ports and allow connectivity of multiple serial devices such as industrial instruments, point-of-sale (POS) terminals, and barcode printers.

What is a USB Hub: How Does It Work » Electronics Notes

Use highest USB version hub where speed is important: Often high speed connections may be required via the USB hub. For example, in some cases an Ethernet connection to the Internet may be made via the hub, or a large capacity disk drive - these connections should be made via the fastest USB hub available. To achieve this, the USB hub will contain some sophisticated electronic circuitry to enable it to perform the required functions - in some instances this may mean the hub consuming reasonable amounts of power and becoming quite warm to touch. This needs to be remembered when connecting large numbers of peripheral devices to a USB hub. ... The power that can be supplied by a USB 1 or USB 2 port is 500 mA maximum per port and 900mA for a USB 3 port on a Type A connector (USB C ports can supply more). This means that a compliant bus powered hub, i.e. Some hubs may become warm: With the level of functionality contained within some of the more complicated USB hubs, large amounts of processing are required. This means that the hubs will consume power and will become quite warm.

USB Hub (Universal Serial Bus Hub): USB hubs cater to the connectivity of USB devices with computers. They provide additional USB ports for expanding a computer's connection options, allowing users to connect multiple peripherals such as keyboards, mice, printers, external storage devices, and more. Half-Duplex Communication: Devices connected to the hub operate in half-duplex mode. This means that they can either transmit or receive data but not both simultaneously. A hub is a networking device that serves as a central point for connecting multiple devices in a local area network (LAN). Its primary function is to facilitate communication among these devices by receiving data from one device and then broadcasting it to all other connected devices. The primary motivation behind creating hubs was to simplify resource sharing among LAN-connected computers, including the sharing of vital assets like printers, files, and various networked resources. Additionally, hubs offered an accessible way to physically connect computers and devices within a network, eliminating the need for complex configuration or routing processes.
