Serial Device Server Exsys EX-61004 — 4x RS232/422/485 ports, includes power adapter

Exsys EX-61004 is a compact serial device server that provides four configurable serial ports compatible with RS232, RS422 and RS485 standards. Supplied with a power adapter, the unit connects serial equipment to Ethernet networks, enabling remote access, centralized data collection and integration of legacy devices into modern IP-based systems. The device supports configurable port modes so you can match the interface to a range of industrial controllers, sensors and measurement instruments.

Advantages

The Exsys EX-61004 offers flexible serial interface selection across four ports, allowing RS232, RS422 or RS485 operation per port. Including a power adapter simplifies installation and reduces the need for additional accessories. Its network-enabled design allows remote management and monitoring of connected serial devices, reducing the need for on-site access. The compact form factor and clear port configuration make it suitable for rack or panel installations where space and reliability are important.

Suitable for

• Connecting industrial controllers and PLCs to IP networks
• Remote monitoring of sensors and measurement instruments
• Integrating legacy serial devices into modern SCADA or IoT systems
• Centralizing serial device data for logging and analysis

Key specifications

• Serial ports: 4 configurable ports supporting RS232, RS422 and RS485 signaling
• Network interface: Ethernet connectivity for device-to-network communication
• Power: Supplied with an external power adapter for immediate operation
• Form factor: Compact enclosure suitable for desktop, DIN-rail or panel mounting depending on installation
• Protocol support: Typical serial-to-Ethernet conversion and remote serial management

How to use

Install the Exsys EX-61004 in a location with network access and a nearby power outlet. Connect each serial device to the appropriate port and configure the port mode (RS232, RS422 or RS485) and serial parameters (baud rate, parity, data bits, stop bits) to match the attached equipment. Connect the server to the Ethernet network and assign an IP address via DHCP or manual configuration. Use the device’s management interface to set up serial-to-IP mapping, security settings and monitoring options. Test communication with each serial device using a terminal application or the host software that will receive the serial data over the network.

Recommendations

Place the device in a protected environment away from strong electromagnetic interference and ensure proper grounding where required. Match serial parameters exactly to the connected equipment and verify wiring for differential pairs on RS422/RS485 lines. Use stable network and power sources to ensure consistent remote access and consider implementing network-level security and access controls when exposing serial devices to wider networks.
