Key uses
The MS51U transmitter and it’s matching receiver operate as a pair to give KVM functionality.
From the transmitter, it is possible to control up to 3x local PCs (2x USB-C & 1x HDMI), whilst from the receiver end, there is also the ability to control a further local PC attached to the remote receiver itself via its HDMI input, or can choose from the HDBaseT output of the switcher.
Auto Switching with Fall-Back
Manual and Automatic input switching is possible. When the currently viewed input is lost or disconnected, the Fall-Back function, enables another predefined input to be automatically selected. any with the added ability to switch back to any chosen input upon loss of the current input. The options are: Next Input, USB-C 1, USB-C 2, HDMI 3, HDMI 4, or HDMI 5.
The receiver can also be set to Auto-Switch to view its own source selection. This can be set to sense a live video input signal, or set to HDMI 5volt sensing.
Hotkey Commands
From the Keyboard and Mouse connected to the remote RX, Hotkey can control which source is to be viewed or selected to control. A choice of Full Screen Single View or Multi-View modes can also be selected in this manner. When in Multi-View mode, the PC that is shown in ‘Window 1’ can be used via the Keyboard and Mouse as the current KVM PC source. Any input can be switched to Full View Single Source Mode. So therefore, controlling the various KVM PC sources is easily done. The following Multi-View mode settings, can all be controlled by using Hotkey commands.
Multi-View Modes
The various view modes are: Single Full Screen, Dual View, Triple View, Quad View, PIP.
The Picture-in-picture window can be moved to any corner of the Quad view. Any source can be chosen to be put into the ‘Multi-View window’ of your choice, by hotkey or RS232 commands.
