Serial Device Server Exsys EX-6122-2POE — Ethernet to 2×RS-232/422/485 with PoE and 12V/3A power supply

The Exsys EX-6122-2POE is a serial device server that converts Ethernet to two independent serial ports supporting RS-232, RS-422 and RS-485 standards. The unit provides network access to legacy serial devices, enabling remote monitoring, control and data collection over IP networks. The EX-6122-2POE supports Power over Ethernet (PoE) for simplified installation and is supplied with a 12V/3A power adapter for environments without PoE or as an alternative power source.

Advantages

The EX-6122-2POE consolidates two serial interfaces into a single networked device, reducing cabling and rack space while providing protocol flexibility between RS-232, RS-422 and RS-485. PoE support allows installation where local power outlets are not available, and the included 12V/3A supply provides an immediate alternative power option. The device is intended for industrial and networked serial device integration, allowing remote access and centralized management of connected equipment.

Suitable for

• Connecting legacy RS-232/RS-422/RS-485 instrumentation to IP networks
• Remote monitoring and control of industrial devices and sensors
• Serial device consolidation in server rooms and edge network locations
• Environments where PoE simplifies installation and reduces cabling

Key specifications

• Network interface: Ethernet with Power over Ethernet (PoE) support
• Serial interfaces: two independent ports selectable for RS-232, RS-422 or RS-485
• Power options: PoE or external 12V DC, 3A adapter included
• Application: enables remote access, monitoring and control of serial equipment over IP

How to use

Install the EX-6122-2POE on your local network by connecting an Ethernet cable to an appropriate PoE-capable switch or injector, or use the supplied 12V/3A power adapter if PoE is not available. Configure the device using its network interface and assign IP settings according to your network policy. Connect legacy serial equipment to the two serial ports, set the required serial mode (RS-232, RS-422 or RS-485) and configure baud rate, parity and flow control as required by the connected devices. Use the provided management tools or standard network protocols to map serial ports to network clients and to enable remote communication.

Recommendations

For reliable operation in industrial environments, mount the device in a protected location away from excessive vibration, moisture and temperature extremes. When using PoE, verify that the switch or injector supports sufficient power class for the device. Match serial line settings precisely to connected equipment and use shielded cables where recommended to minimize interference when deploying RS-422/RS-485 links.
