Serial Device Servers are specialized network appliances designed to transfer data between a serial port and an Ethernet network. These devices allow serial-based equipment such as barcode scanners, card readers, and industrial machinery to communicate with networked computing platforms, enabling centralized control and remote access. The main function of a Serial Device Server is to encapsulate serial data into packets suitable for transmission over an IP network, thereby bridging the gap between old and new technologies without the need for costly hardware upgrades.
Among their primary uses, Serial Device Servers are integral in various applications including industrial automation, point-of-sale systems, and access control systems, where they offer characteristics such as reliability, real-time data transmission, and easy integration into existing networks. They support various serial protocols and standards, ensuring broad compatibility with a wide range of devices. These products are particularly admired for their ability to extend the lifespan of legacy equipment, facilitate remote management, and provide secure communication through advanced encryption methods. Key manufacturers of Serial Device Servers include companies like Moxa, Advantech, and B&B Electronics.
