Chapter 2: Overview
2. Overview
2.1 Introduction
The ServSwitch 4site Flex enables you to simultaneously display and manage four computers on a single console. It combines key
features of a high-end Keyboard/Video/Mouse (KVM) switch and a digital multiviewer, scaling and converting videos at both
inputs and output.
Display Modes
There are four display modes: Quad mode, Full-Screen mode, PiP mode, and Win mode.
Quad mode: In this mode, the screen is split into four fields of equal size, each displaying the entire screen contents of one source.
NOTE: If only (2) channels are active, you can go dual-screen instead of quad-screen. To do this, press the quad-screen button
when only (2) channels are available.
Figure 2-1. Quad mode screen.
Full-Screen mode: In Full-Screen mode, one of the four sources is displayed in full-screen size and maximum resolution.
Figure 2-2. Full-Screen mode screen.

724-746-5500 | blackbox.com Page 11
Chapter 2: Overview
PiP mode (Picture in Picture): Using this feature, the full-screen display of one of the four video sources is accompanied by one to
three small images (thumbnails) of the other video sources that are displayed on the right hand side of the screen. This enables
simultaneous monitoring.
Figure 2-3. PiP mode screen.
Win mode: In Win mode, each video source is displayed in its own separate, detached window. Position each of these windows
and adjust their width and height. Set transparency. To position a window, use either the Hotmouse function, the front panel or
the touchscreen. You can save presets of the window positioning.

Chapter 2: Overview
2.2 Features
2.2.1 DVI and VGA
Supports resolutions of up to 1920 x 1200 @ 60 Hz for both DVI and VGA.
Any combination of DVI and VGA at all standard resolutions is possible at inputs and output. Analog video input is converted to
digital. If an analog display is connected, ServSwitch 4site Flex converts the digital signal to analog at the output. Internally,
ServSwitch 4site Flex processes video purely digitally, guaranteeing superior digital image quality.
2.2.2 USB and Keyboard for Keyboard/Mouse/Touchscreen/Trackball
Use either PS/2 or USB ports on the computer to connect the keyboard and mouse to ServSwitch 4site Flex. It supports any
combination. To connect the console, ServSwitch 4site Flex features two USB ports for mouse, keyboard, touchscreen, or trackball
connection.
2.2.3 Transparent USB 2.0
ServSwitch 4site Flex features a transparent high-speed USB 2.0 matrix: USB 2.0 devices (for example, printer, external memory,
memory stick, Webcam, 3D mouse, finger printer) can be switched to the connected computers.
2.2.4 Operation
There are six ways to operate ServSwitch 4site Flex, switch channels, and select display modes:
1. Using the buttons on the front of the unit.
2. Using configurable hotkeys.
3. Using the unit’s external configuration software on a remote computer.
4. Via a serial port using the protocol DCP XML.
5. Using mouse functions (Hotmouse).
6. Using a touchscreen.
Configure the ServSwitch 4site Flex via an on-screen display (OSD) that you can open and navigate using either keyboard
commands or front-panel buttons.
The LEDs on the front panel indicate the unit’s current status.
Use the serial (RS-232) or USB port for remote control and firmware updates.

Selector
Figure 2-6. Selector screen.
You can also select the active channel using hotkeys and the arrow keys. The selection window closes once the channel selection
timeout period has expired. The channel selection timeout is configured in the OSD under SYSTEM > QUAD MODE.
Use the “Time out of channel selection:” menu item to define how long the selector is to be displayed.
Setting output resolution to safe output modes
To set output resolution to 640 x 480 pixel @ 60 Hz simultaneously:
Press and hold Buttons 1 and 2 for 2 seconds. Use this feature when you cannot use the OSD (on-screen display is dark or
illegible) because the output resolution setting is not supported by the monitor. After setting the correct output resolution (640 x
480 @60), you can choose a resolution the connected monitor supports in the OSD.
Alternatively, hold Buttons 1 and 2 again to cycle through the following video modes: VGA 640 x 480 @ 60, SVGA 800 x 600 @
60, XGA 1024 x 768 @ 60, UXGA 1600 x 1200 @ 60, and the preferred video resolution found in the monitor EDID.
LEDs 1 to 4 and FULL indicate the selected mode in blue.
Hardware Reset
Press and hold Buttons 3 and 4 simultaneously for 5 seconds to reset the unit completely (video + mouse + keyboard)
Calling up OSD
Press and hold PiP and Win buttons simultaneously for 2 seconds to open the OSD menu.
NOTE: While the OSD menu is open, the active computer can still be operated by mouse or touchscreen.
