INTRODUCTION

Congratulations on your purchase of the 8x1 DPKVM Switcher. Your complete satisfaction is very important to us.

Gefen

Gefen delivers innovative and progressive computer and electronics add-on solutions that harness integration, extension, distribution, and conversion technologies. Gefen’s reliable plug-and-play products supplement cross-platform computer systems, professional audio/video environments, and HDTV systems of all sizes with hard-working solutions that are easy to install and simple to operate.

The Gefen 8x1 DPKVM Switcher

Easily switch between eight computers using DisplayPort with the Gefen 8x1

DPKVM Switcher.

The rack-mountable Gefen 8x1 DPKVM Switcher offers an economical solution for switching between eight different computers to one display location.

In addition, USB peripherals and audio are carried at the same time from each source making this a very versatile solution.

Eliminating the need to purchase many displays, keyboards, and other accessories for each computer in a studio or professional environment, this versatile solution saves money, supports both Mac and PC-type computers, and offers uncluttered and increased desktop space.

The 8x1 DPKVM Switcher outputs are: One DisplayPort, two USB 2.0 ports

(used for keyboard, mouse and other USB 2.0 peripherals) and an analog L/R audio. This Switcher can be controlled using front-panel discrete switching, IP control, the included IR Remote control, or the RS-232 port for switching automation.

The 8x1 DPKVM Switcher is compatible with all operating systems using Display-

Port and USB.

How It Works

Connect the eight included 6 foot DisplayPort cables between the computers and the Switcher inputs. Connect the eight included USB cables between the computers and the USB inputs. Connect the eight included audio cables between the computers and the audio inputs. Connect the Switcher output to the monitor using a DisplayPort cable. Connect the Switcher USB outputs to the USB peripherals. Connect the Switcher audio cables to the audio devices. Connect the included 5V DC locking power supply to the 8x1 Switcher and connect the AC power cord to an available electrical outlet. The currently selected source will be displayed

IR REMOTE CONTROL UNIT

Installing the Battery

1. Remove the battery cover on the back of the IR Remote Control Unit.

2. Insert the included battery into the open battery slot. The positive (+) side of the battery should be facing up.

3. Replace the battery cover.

The Remote Control unit ships with two batteries. One battery is required for operation and the other battery is a spare.

Battery Slot

WARNING: Risk of explosion if battery is replaced by an incorrect type.

Dispose of used batteries according to the instructions.

IR REMOTE CONTROL UNIT

Setting the IR Channel

In the event that IR commands from other remote controls interfere with the supplied IR Remote Control unit, changing the IR Remote Control’s IR channel will fi x the problem. The IR Remote Control unit has a bank of DIP switches used for setting the IR channel. The DIP switch bank is located underneath the battery cover.

Left: Picture of the opened rear battery compartment of the IR remote showing the exposed DIP Switch bank between the battery chambers.

Corresponding DIP Switch Settings for each IR Channel

It is important that the IR channel on the Remote Control unit, matches the IR channel set on the 8x1 DPKVM Switcher. For example, if both DIP switches on the IR Remote Control unit are set to IR channel 0 (both DIP switches down), then the 8x1 DPKVM Switcher must also be set to IR channel 0. See page 21 on how to change the IR channel on the 8x1 DPKVM Switcher.

TELNET CONTROL

The Gefen 8x1 DPKVM Switcher supports Telnet for controlling the Switcher over a network. To access this feature, an IP address, subnet, gateway, and port numbers need to be set correctly. Consult the network administrator to obtain the proper IP address and settings for this product to properly communicate with the

Switcher over a network.

The Telnet control must be confi gured using RS-232 commands. Once properly confi gured, enter the IP address that was assigned to the Switcher using a terminal program or other Telnet client.

1. Connect the Switcher to a computer using RS-232.

2. Use a terminal emulation program (e.g. HyperTerminal, PuTTY, Indigo, etc.) to connect to the Switcher. See page 14 for information on RS-232 confi guration.

IMPORTANT: When using HyperTerminal under Windows XP,

the LF (line feed) character option must be enabled.

3. Apply power to the Switcher. Information similar to the following will be displayed in the terminal window:

===================================================

GEFEN

DISPLAY PORT 841

FW version: 1.3

TELNET CONTROL

the command to set the IP address for the Switcher. Check with a network administrator to obtain an available address, if necessary.

DHCP is not supported by this Switcher.

#sipadd 192.168.2.234

New IP set to: 192.168.2.234

After setting the IP address, power-cycle the Switcher for the changes to take effect.

IMPORTANT: All IP confi guration changes will require the

Switcher to be power-cycled.

6 Specify the IP of the Switcher in the Telnet client. In this example, the IP address is set to 192.168.2.234. Once connected to the Switcher, the Telnet client will display a screen similar to the following:

----------- Welcome to DP841 Telnet Server ----------

You are user number 1 of 3 allowed.

You will be disconnected after 10 minutes of inactivity.

Login: Admin

Password: Admin

Type Cmd:

By default, the user name and password options are enabled by use of the #use_telnet_pass command (see page 20). Once this command is enabled, the Switcher will prompt for both the user name and password.

The password cannot be disabled from the login process. Once logged in, the Type Cmd prompt will be displayed.

The Telnet interface uses the same commands and syntax that are used with

RS-232 control. See the command list, starting on page 15.

25

FIRMWARE UPDATE

Firmware Update Procedure

Any terminal emulation program can be used to perform the upgrade process. The instructions below is outlined for Windows® HyperTerminal.

1. Connect an RS-232 cable between the Switcher and the computer running the terminal program. Verify the correct serial port settings (see page 14).
