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, the
included IR Remote control, or the RS-232 port for switching automation.
The 8x1 DPKVM Switcher is compatible with all operating systems using DisplayPort 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.

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 fix 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.

opened rear battery
compartment of the IR
remote showing the
exposed DIP Switch
bank between the battery

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 configured using RS-232 commands. Once properly
configured, 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
configuration.
IMPORTANT: When using HyperTerminal under Windows XP,
the LF (line feed) character option mustt 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
===================================================
4.
Use the #ipconfig command to display the current IP settings. The factory
(default) settings are displayed below:

is set to ON
Note that the Telnet password is set to ON. A user name and password can
be set for additional security. This option can also be disabled. See page 20
for details.
24
TELNET CONTROL
5.
Use the #sipadd 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 configuration 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).
2.
Type the #activebolo command then press the [ENTER] key.
3.
Repeat Step 2.
The following will be displayed on the screen:
================== Main Menu ========================
Download new program -------- 1
Cancel ---------------------- 2
=====================================================
4.
Press [1] on the computer keyboard to begin downloading program to the
htemporary memory.
5.
The following message will be displayed:
Waiting for the file to be sent ... (press ‘a’ to abort)
6.
In Hyperterminal, click Transfer > Send File...
7.
Click Browse... and select the .bin file to be uploaded (e.g. 1x4splitter.bin).
8.
Select the Ymodem protocol.
9.
Click Send on the Send File dialog box.
