INTRODUCTION
The DPN-4P is a dedicated multi-platform KVM switch capable of managing up to 4 different computers
with a DisplayPort monitor, one USB keyboard & mouse.
The USB emulation technology utilized by the DPN-4P enables immediate hotkey source switching
through a remote USB keyboard and mouse. The DPN-4P uses DisplayPort connectors providing high
resolutions of up to 4K (3840x2160 @ 30Hz) with zero pixel loss from TMDS signal correction.
SOURCE SWITCHING MADE EASY
The DPN-4P provides a simplified management approach for up to 4 computers with DisplayPort, stereo
audio, and USB 2.0 outputs. This dynamic KVM console can be controlled remotely from easily accessible
keyboard hotkeys or RS-232 commands, as well as directly through the console’s easy to read front
panel.
FULL USB KEYBOARD AND MOUSE EMULATION
The USB keyboard and mouse emulation utilized by the DPN-4P provides accurate and quick source
switching by means of keyboard hotkeys. The DPN-4P imitates the presence of a keyboard and mouse for
every attached computer through a USB cable. This is essential as it simulates the existence of the key-
board and mouse to all the computers while switching without interruptions.
FEATURES
 Zero pixel loss with TMDS signal correction
 Supports all USB 2.0 Devices
 Control Sun, Mac or PC computers from a common KVM console
 Compatible with all major software including Windows, Linux, Mac OS, Sun OS, Unix
 Rack mountable in a standard 19 inch rack
 Balanced stereo audio output
 RS-232 control for remote control
 Optional TCP/IP control
 Hot-key commands for quick channel selection.
 Complete keyboard emulation for error free booting
 Top quality 4K (3840x2160 @ 30Hz)
APPLICATIONS
The DPN-4P has a broad range of applications, but the main function of this KVM switch is to centralize
the access of several computers into one comprehensive PC. Not only does it function as a KVM console,
it also supports USB 2.0 functionality. This allows a user at the console to use USB devices that would
otherwise be unavailable with conventional KVM devices. For example, it allows a user to use a flash
memory drive or camera without having to plug it directly into the remote computer. The DPN-4P is a per-
fect solution for the medical or industrial field, where it may not be practical or safe to have one or more
computers in the general vicinity.

Hotkey Commands
A Hotkey command is a keyboard sequence used to trigger an action on the DPN-4P through the use of
the keyboard connected on the USB port of the DPN-4P. To activate the hotkey sequence, press the CTRL
key twice and then enter the desired hotkey commands. Hotkey commands are listed below.
RS-232 Control
RS-232 control allows for remote control of the DPN-4P. See the section on establishing an RS-232 con-
nection in this manual. Set the connection to 9600 N,8,1, No flow control. RS-232 commands are listed
below.

ESTABLISHING AN RS-232 CONNECTION
Before you start:
Controlling a Smart-AVI device via RS-232 requires an RS-232 card installed on your computer or a USB
to RS-232 adapter. Below are instructions on how to create an RS-232 connection between a PC and the
Smart-AVI device.
Use terminal client software such as the PuTTY to connect to the Smart-AVI device. Make sure to use
communication settings 9600 bps, N, 8, 1, No flow control.
Check the device and your PC to determine if you need a male to male or a male to female cable and how
long it needs to be. The Smart-AVI device requires a straight through cable. You can use a Null Modem
Adapter to convert a crossed cable to a straight through cable. Examples of crossed and straight thorough
cable pin-outs are shown below. The standard maximum length for an RS-232 cable is 50 feet. Call our
Smart-AVI Support Engineer if you require more information.
Figure 7-1
Examples of 9 pin RS-232 Straight Through and Crossed Cables
Establish a connection to the Smart-AVI device:
1. Connect an RS-232 cable to the RS-232 connector on the PC.
2. Connect the other end of the cable to the RS-232 port of the Smart-AVI device.
3. Use Windows Control Panel / Device Manager to identify the Com port number. See instructions and
Figure 7-2 below.
4. Power on the device.
If you are using a USB to COM port adapter on a Win-
dows PC and need to identify the COM port used, do
the following:
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 name of your adapter and the
COM port number in use.
