Chapter 3
Operation
Overview
This chapter provides detailed information on the features of the VP1920’s on-
screen display (OSD), and how to locally operate the unit using the front-panel
pushbuttons and the IR remote control.
Operation Considerations
Make sure to use the IR remote control within the effective range (6 m), and
that there is a clear line-of-sight between the remote control unit and the IR
receiver connected to the VP1920.
The IR remote control and the VP1920’s front panel offer the same
operation capability. Use either method as required.
Switching the Display Source
Auto Switching
By default, VP1920 automatically switches to a new source on Display A as
soon as the source is detected. To disable automatic switching, press the Menu
button/pushbutton, and then go to Source > Auto Switch to disable the setting.
Manual Switching
You can manually switch the display source using the IR remote control and
the front-panel pushbuttons.
1. Skip this step if your displays are set to the mirror mode.
Press a Display button/pushbutton to focus a display. The pushbutton for
the selected display lights amber.
Note: If your displays are set to the PiP mode, press the Display A
pushbutton to focus the main display, and press the Display B
pushbutton to focus the inset window.

Operating PCs/Laptops/Tablets
You can control connected PCs, laptops, and/or tablets using a keyboard and a
mouse attached to your VP1920.
Hardware Setup
Follow the steps below to correctly install your PCs and/or laptops.
1. Connect your PC or laptop to Source 1 or Source 2 of the VP1920
depending on the equipped interface (VGA, DisplayPort, or HDMI).
2. Use a USB cable to connect your device to the USB host port of the Source
group on the VP1920 that you use in step 1.
3. Connect a keyboard and a mouse to the back panel of the VP1920. Make
sure to connect the keyboard and mouse to their indicated USB port.
Operation
By default, the VP1920 is set to automatically switch the control to the source
that Display A shows. For example, if you have a laptop connected to Source 1,
and the source is displayed on Display A, you can then control the laptop using
the keyboard and mouse connected to the VP1920. In this case, the Keyboard/
Mouse and peripherals LEDs for “1” light amber to indicate that the keyboard/
mouse control is switched to Source 1, and that the Source 1 device (your
laptop) can now access any USB devices attached to the VP1920.
To protect confidential data from leaking, you can limit the access of USB
peripherals to a particular source, and that the access will only be allowed when
Display A is assigned with that particular source. Press the Menu button/
pushbutton, navigate to USB > Peripherals and select Source 1 or Source 2.

Rack Mounting
Before working on the rack, make sure that the stabilizers are secured to
the rack, extended to the floor, and that the full weight of the rack rests on
the floor. Install front and side stabilizers on a single rack or front stabilizers
for joined multiple racks before working on the rack.
Always load the rack from the bottom up, and load the heaviest item in the
rack first.
Make sure that the rack is level and stable before extending a device from
the rack.
Use caution when pressing the device rail release latches and sliding a
device into or out of a rack; the slide rails can pinch your fingers.
After a device is inserted into the rack, carefully extend the rail into a
locking position, and then slide the device into the rack.
Do not overload the AC supply branch circuit that provides power to the
rack. The total rack load should not exceed 80 percent of the branch circuit
rating.
Make sure that all equipment used on the rack – including power strips and
other electrical connectors – is properly grounded.
Ensure that proper airflow is provided to devices in the rack.
Ensure that the operating ambient temperature of the rack environment
does not exceed the maximum ambient temperature specified for the
equipment by the manufacturer.
