4Port Ethernet Controller

The Kramer FC-24ETH is a 4-port serial control gateway that extends device control across a customer Ethernet LAN. It connects IP-based control clients with equipment operated through bidirectional RS-232 or RS-485 serial connections. Multiple clients can connect to the gateway over IP, while concurrent control is supported for two compatible serial devices. This design is intended for remotely controlling equipment such as AV scalers, video displays, and audio amplifiers.

Ideal Use Cases

The FC-24ETH fits AV systems that require serial device control through an existing Ethernet network. It can provide remote access to RS-232 or RS-485 controllable equipment without changing the control method used by the connected devices. Suitable applications include installations containing AV scalers, displays, or amplifiers that need to be operated by IP-connected control clients. Its support for multiple clients is also useful when more than one control interface must communicate with the gateway.

Why Choose This Model

This model combines Ethernet connectivity with two widely used forms of serial control. Bidirectional RS-232 and RS-485 communication allows commands and device responses to pass through the gateway, supporting control interactions that require communication in both directions. The supplied product information also specifies plug-and-play deployment over a customer Ethernet LAN. For installations already using network-based control clients, the FC-24ETH creates a direct link between those clients and serially controlled AV equipment.

Installation and Integration

Deployment centers on connecting the FC-24ETH to the customer Ethernet LAN and integrating compatible equipment through RS-232 or RS-485 serial control connections. Control clients then connect to the gateway over IP. Multiple IP-connected clients can access the unit, and two RS-232 or RS-485 controllable devices can be controlled concurrently. This arrangement allows network clients and serial devices to remain within their respective connection environments while the gateway provides the communication path between them.

Performance Highlights

The principal performance capability is concurrent control of two compatible devices through bidirectional serial connections. Because the gateway supports both RS-232 and RS-485, it can serve installations containing equipment that uses either stated serial standard. Multiple control clients can maintain IP connections to the gateway, enabling more than one client to participate in the control system. The Ethernet LAN provides the network connection used for remote access, while the serial interfaces connect to the controlled equipment.

What Makes It Different

The FC-24ETH is specifically identified as a 4-port serial control gateway rather than a general-purpose Ethernet accessory. Its role is to bridge IP-connected control clients and customer-controlled serial devices. The combination of multiple IP client connections, bidirectional RS-232 or RS-485 communication, and concurrent control of two devices defines its application. This focused design makes it relevant to AV environments where scalers, video displays, or audio amplifiers must remain serially controlled while becoming accessible through an Ethernet LAN.

Final Assessment

For systems that need to connect network-based control clients with RS-232 or RS-485 AV devices, the FC-24ETH provides a clearly defined gateway function. It supports plug-and-play LAN deployment, multiple IP-connected clients, bidirectional serial communication, and concurrent operation of two controllable devices. These capabilities make it a practical choice when remote Ethernet control must be added to compatible serially controlled equipment.
