Serial Device Server Exsys EX-6122-2 — Ethernet to 2× RS-232/422/485, requires 12V/3A power

Exsys EX-6122-2 is a compact serial device server that provides Ethernet-to-serial conversion with two independently configurable ports. Each serial port supports RS-232, RS-422 and RS-485 standards, allowing integration of legacy equipment and modern IP networks for remote monitoring, control and data acquisition. The unit requires an external 12V/3A power supply and is intended for environments where reliable serial-to-Ethernet connectivity is needed.

Advantages

The Exsys EX-6122-2 offers flexible serial interface options with automatic or manual selection between RS-232, RS-422 and RS-485 per port, enabling connection to a wide range of devices without additional converters. Dual-port capability allows two independent serial devices to be networked over a single Ethernet link, simplifying system architecture. The device server supports standard network protocols for remote access and centralised data collection, reducing the need for on-site intervention. Its compact design and external power requirement make it suitable for mounting in cabinets or on DIN rails where space and power distribution are constrained.

How to use

Install the EX-6122-2 in a location with stable network connectivity and appropriate environmental protection. Connect the Ethernet cable to the network port and attach serial devices to the two serial ports using the correct wiring and connector type for RS-232, RS-422 or RS-485. Provide a 12V/3A DC power supply to the unit. Configure network parameters and serial port settings through the device's web interface or configuration utility to match the connected equipment's communication parameters. Once configured, serial devices become accessible over the IP network for remote monitoring, data collection and control.

Recommendations

Verify serial wiring and ground connections for each device before applying power, and choose the appropriate serial standard per port to match connected equipment. Use a regulated 12V/3A power supply with sufficient surge protection. For installations in electrically noisy environments, enable shielded cabling and proper termination for RS-422/RS-485 links to ensure reliable communication.
