OVERVIEW

D2H-4p Duo is a dedicated multi-platform KVM switch capable of managing four 4K computers through a single, central workstation. Built with ultra-HD ready HDMI outputs, the D2H-4p Duo offers full video emulation directly from the device. Up until now, DisplayPort switches lost emulated picture when disconnected from monitors, leading to confusion and disorganization upon reconnecting. With the D2H-4p Duo, full EDID-assisted HDMI video emulation ensures visual workspaces and screen resolutions are remembered every time. The D2H-4p Duo is DisplayPort 1.2 and HDMI compliant, supporting screen resolutions up to 4K Ultra-HD (3840x2160 @ 30Hz) for remarkable and responsive video emulation. Additionally, the

D2H-4p Duo is USB peripheral-friendly. The D2H-4p Duo is also easy to control with both a simple frontpanel interface, as well as RS-232 functionality.

SOURCE SWITCHING MADE EASY

The D2H-4P Duo offers simplified management between four DisplayPort equipped computers’ USB 2.0 outputs.

Keyboards, mice, and other connected USB devices can be switched between with ease. This dynamic KVM console can be controlled via hot keys or RS-232 commands, as well as directly through the console’s easy-to-read front panel.

EDID PASS-THROUGH AND RECOGNITION

The D2H-4P Duo features EDID Pass-Through technology and source recognition, which enables smooth and efficient switching in virtually any scenario. This plug-and-play EDID functionality makes set up hassle free and simple.

FULL USB KEYBOARD AND MOUSE EMULATION

The USB keyboard and mouse emulation utilized by D2H-4P Duo provides quick source switching via keyboard hot keys. D2H-4P Duo simulates the presence of a keyboard and mouse for every attached computer through a USB cable. This essential function simulates keyboard, video, and mouse control for all connected computers, so switching between each is kept seamless and completely uninterrupted.

FLEXIBLE CONTROL

USB/KEYBOARD: Hot keys enable the user to switch and control all the different functions of the KVM switch. RS-

232: Any external device or program supporting RS-232 can control the D2H-4P Duo. The D2H-4P Duo uses a very simple protocol that enables easy integration with other devices.

FLEXIBLE SHARING

INDEPENDENT SIMULTANEOUS DEVICE SELECTION: Flexibility is key with the D2H-4P Duo. It enables the use of a

USB keyboard and mouse of one computer while other USB peripherals such as scanners and printers are connected to other computer sources. D2H-4P Duo maintains the ability to switch all connected devices to any one of the computer sources as with any other KVM switches.

REAL-WORLD APPLICATIONS

The D2H-P Duo has a broad range of applications, but the main function is to centralize the access of up to four computers that support DisplayPort displays in a single workstation. Not only does it function as a KVM console, but it also supports USB 2.0 functionality. This allows users to access nearby USB devices, including those not supported by other KVM switches. The D2H-4P Duo is the ideal solution for medical, industrial, studio and defense applications, where it is not practical or safe to have multiple computers in the vicinity of the workstation.

RS-232 CONTROL

Controlling the D2H-4P Duo via RS-232 requires an RS-232 card installed on your computer or a USB to RS-232 adapter. Check the D2H-4P Duo and your Computer to determine if you need a male to male or a male to female cable and how long it needs to be. The D2H-4P Duo requires a straight through cable. You can use a Null Modem Adapter to convert a crossed cable to a straight through cable. An example of a straight through cable pin-out is shown in Figure 7-1. The standard maximum length for an RS-232 cable is 50 feet. Call our Smart-AVI Support Engineer if you require more information.

You will need to identify the COM port number used. On a Windows PC:

1. Click on the start button.

2. Click on Control Panel.

3. Click on Device Manager.

4. Click on the arrow next to Ports (COM &

LPT).

You should see the COM port number in use.

See Figure 7-2

Run the terminal client of your choice such as HyperTerminal or PuTTY. Select the correct COM port on the  computer. Use the following connection settings:  9600, N, 8, 1, no flow control. 

Cycling power on your unit will display a boot up message in your terminal software if the connection is cor‐ rect.  

 

NOTE: Your terminal software may not default to or display all of the settings above. If you attempt to connect and the settings above are not set correctly, after you set them correctly you may need to cycle power on your unit for communication to be established.
