HSL Secure 2-Port KVM Combiner Switch
HSL’s Secure 2-Port KVM Combiner enables viewing and controlling
two computers:
•On the same display
•Using a single set of keyboard, mouse, USB, and audio peripherals
HSL’s KVM Combiner is the only product that combines a scaler, multi-
viewer, KVM switch, and video-wall controller - built into one.
The KVM Combiner was built according to multiple international-
security standards. These assure total isolation. So, no data leaks
between the two connected computers, via the switch or the
connected peripherals.
This guide tells you how to install, operate, and configure an HSL Secure
2-Port KVM Combiner.
