Know before you buy
Yes, the ADDERLink INFINITY 2122 is specifically designed for dual-head setups. It supports either one display at 2560x1600 or two displays at 1920x1200 resolution, both at 60Hz.
It is designed to operate over a standard 1GbE network. While it can share existing infrastructure, we recommend using a managed network switch to ensure sufficient bandwidth and performance for high-quality video transmission.
Using fiber optic modules, you can extend your connection up to 20km (approximately 12 miles). If you are using CATx cabling, the distance will be limited by standard Ethernet constraints.
Yes, the unit supports USB 2.0 pass-through. It also includes class control, which allows you to disable non-HID devices for enhanced security in sensitive environments.
The 2122 features network teaming, which allows you to connect both SFP ports to your network. This provides redundancy, ensuring that if one network path fails, the connection remains active.
The system is OS-agnostic because it functions at the hardware level. It is fully compatible with Windows, Linux, macOS, and Sun OS, as it simply extends the video, audio, and USB signals from the host machine.
