Vivolink VLEXT100 interface cards/adapter

The Vivolink VLEXT100 is a network serial port expander that connects IP-based control systems to serial AV equipment. It provides TCP/IP or UDP control for Vivolink devices with RS-232 or RS-485 ports, enabling integration of serial-based equipment into modern control ecosystems. The unit includes a metal chassis, 100M Ethernet port, GPIO and IR output, and supports web-based configuration via a built-in web server.

Advantages

The VLEXT100 supports both RS-232 and RS-485 communication standards while offering flexible power options including 12–24V DC or Power over Ethernet (PoE). Its intuitive web interface allows configuration from any browser on PC, tablet or smartphone, and the sturdy metal housing with advanced ESD protection ensures reliable operation in professional environments. The device consumes ultra-low power (0.48W) for energy-efficient installations.

Suitable for

• Integration of serial AV devices into IP-based control systems
• Centralised room control and automation systems
• Environments requiring remote configuration and monitoring
• Installations where PoE or DC power flexibility is needed

How to use

Connect the VLEXT100 to your network using the 10/100M Ethernet port and provide power via a 12–24V DC supply or PoE. Attach serial devices to the RS-232 or RS-485 terminals using the supplied Phoenix connectors and connect any required IR or GPIO lines. Access the built-in web server from a browser on PC, tablet, or smartphone to configure network settings, protocol options (TCP/UDP) and serial port parameters. After configuration, control commands can be sent over TCP/IP or UDP to communicate with connected serial AV equipment.

Recommendations

For reliable operation, mount the VLEXT100 in a ventilated area and use shielded Ethernet and serial cabling where possible. Ensure firmware is kept up to date and configure appropriate network security settings when exposing the device on larger networks.
