2-Port Ethernet Controller

Ideal Use Cases

The FC-22ETH is designed for applications that need to control serial-equipped devices from IP-connected clients over a customer Ethernet LAN. Its two-port design supports concurrent control of two compatible devices through bidirectional RS-232 or RS-485 connections. This makes the gateway suitable for installations involving AV scalers, video displays, audio amplifiers, or other equipment that accepts either of the supported serial control standards.

It is especially relevant when several control clients need network access to the same pair of serial-controlled devices. Instead of limiting operation to a single local serial controller, the FC-22ETH enables multiple clients to connect through IP and issue control commands to the attached equipment.

Why Choose This Model

The FC-22ETH combines Ethernet connectivity with two serial control ports in a dedicated control gateway. It bridges IP-connected control clients and equipment operated through RS-232 or RS-485, allowing serial devices to participate in an Ethernet-based control workflow.

Support for multiple concurrently connected control clients distinguishes the unit from a basic point-to-point serial connection. A compatible control system can access two attached devices while additional IP-connected clients remain available for control. Bidirectional serial communication also allows control traffic to travel in both directions between the clients and connected equipment.

Installation and Integration

The gateway is described as capable of plug-and-play deployment over a customer Ethernet LAN. Integration centers on connecting the FC-22ETH to that LAN and attaching as many as two controllable devices through bidirectional RS-232 or RS-485 serial connections. The serial standard used should correspond to the interface supported by each connected device.

Because control clients connect to the gateway through IP, they can communicate with the serial-controlled equipment through the existing Ethernet environment. This arrangement provides a clear connection path: control clients connect over IP, the FC-22ETH serves as the Ethernet-to-serial gateway, and the two serial ports connect to the target devices. Published source data does not specify configuration software, connector details, dimensions, power requirements, or included accessories.

Performance Highlights

The principal performance capability is concurrent control. Multiple control clients can be IP-connected to the FC-22ETH at the same time, while the gateway provides control access to two RS-232 or RS-485 devices. This is useful when more than one client must interact with the connected AV hardware rather than relying on a single control station.

Both supported serial connection types are bidirectional. The available information does not state network data rates, serial baud rates, client limits, or protocol-specific performance figures, so no additional throughput or response-time claims are made.

What Makes It Different

The FC-22ETH is purpose-built around a focused combination: Ethernet-based client access, two serial control ports, RS-232 or RS-485 compatibility, bidirectional communication, and support for multiple concurrent control clients. Together, these capabilities address installations where serial-controlled equipment must be available within an IP-connected control system.

The two-port configuration also allows one gateway to serve a pair of compatible devices. The source specifically identifies AV scalers, video displays, and audio amplifiers as examples, giving the unit direct relevance to AV control applications without limiting it to a single equipment category.

Final Assessment

The FC-22ETH provides a direct way to connect multiple IP-based control clients with two bidirectional RS-232 or RS-485 devices over a customer Ethernet LAN. Its plug-and-play deployment capability, dual-device control, and concurrent client access make it a practical control gateway for compatible serial-operated AV equipment. Buyers should verify device protocol compatibility and any installation details not included in the published source information.
