Serial Hubs

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. It serves as a single hardware solution for a secure alternate route to monitor IT, networking, security, and power devices from multiple vendors.

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.

Installing a Serial Hub is ideal if you need to:

• Manage the serial console port on servers, routers, switches, PBX’s, firewalls, etc... over Ethernet or through out-of-band connections
• Replace serial cabling with Ethernet but maintain the use of devices that were active on the serial network
• Set-up virtual COM ports to connect PC or Servers to remote serial devices over Ethernet
• Communicate to multiple serial devices at the same time across a network
• Replace existing serial dial-up modem connections
• Connect serial PLCs or serial signage equipment to Ethernet
