Ethernet–2 x RS-232 -sovitin Exsys EX-6112-2POE, PoE-tuki ja 12V/3A virtalähde

The Exsys EX-6112-2POE Ethernet to 2 x RS-232 adapter provides network connectivity for two RS-232 serial devices. The device bridges legacy serial equipment to IP networks, allowing remote access, monitoring and control over standard Ethernet. It supports Power over Ethernet (PoE) as well as external power via the supplied 12V/3A adapter, enabling flexible deployment in locations without convenient local power. The compact metal housing and industrial-oriented feature set make it suitable for integration into point-of-sale systems, kiosks, control cabinets and other installations that require reliable serial-to-network conversion.

Advantages

The adapter offers dual independent RS-232 ports, enabling simultaneous network access for two serial devices. PoE support simplifies installation by allowing network-supplied power when a compatible switch or injector is available, while the included 12V/3A adapter provides an alternative power source. Network protocol support and transparent serial tunneling reduce the need for changes to existing serial device software. The unit’s rugged enclosure and DIN-rail or desktop-friendly footprint help ensure stable operation in commercial and industrial environments.

Suitable for

• Connecting legacy serial devices (RS-232) to Ethernet networks
• Point-of-sale terminals and receipt printers
• Industrial control systems and PLC communication
• Kiosks, digital signage and self-service terminals
• Remote device management and telemetry collection

Key specifications

• Network interface: 10/100 Mbps Ethernet with PoE support
• Serial interfaces: 2 × RS-232 ports (DB9 signaling)
• Power options: PoE input and external 12V/3A DC adapter
• Mounting: compact metal housing suitable for desktop or cabinet installation
• Operating environment: designed for commercial and light industrial use

How to use

Install the adapter near the serial devices and connect each device to one of the RS-232 ports using appropriate serial cables. Connect the adapter to a network switch or router using a standard Ethernet cable. If PoE is available on the network switch or injector, the adapter can receive power via the Ethernet connection; otherwise, plug in the supplied 12V/3A power adapter. Configure network settings and serial port parameters through the device’s web interface or configuration utility to match the baud rate, parity, data bits and stop bits required by the connected serial devices. After configuration, establish network connections or virtual COM ports on host systems as needed for software communication with the serial equipment.

Recommendations

For reliable operation, verify serial cable pinouts and signal levels before connecting critical equipment. Use PoE when running power over existing structured cabling to reduce wiring complexity, and keep the adapter in a ventilated location to avoid heat buildup. Ensure firmware is kept up to date and secure network access via firewall rules or VLAN segmentation when exposing legacy serial equipment to larger networks.
