INGLE UNIT OR DAISY-CHAIN OPERATION

DKVM-8 has the capability to be Daisy-Chained to 15 more units (for a total of 16), giving
the user control over a maximum of 128 computers.

Each DKVM-8 unit is defined as a “BANK”. See the following diagram for more
information. BANK numbers range from 0 to F (Hexadecimal), for a total of 16 banks.

BANK 0 is the MASTER bank while BANK 1 through F are SLAVE banks. The MASTER
bank is the unit that connects to the console keyboard, mouse and monitor.

The DIP-switch on the rear panel must be set correctly for proper identification and usage.
See the next section for the actual settings. If you are using DKVM -8 in a single unit

configuration, it must be set as the MASTER (BANK 0). If it is to be used as a
SLAVE unit, then it must be set to any unused unique bank number from 1 through
F.

l After setting the DIP-switch on the SLAVE unit, connect the computers using the same

procedure outlined in step 5 to 9 in the previous section. DO NOT POWER UP THE

COMPUTER YET.

l Using the daisy-chain cable, connect one end to the “Master Input / Slave Output” port

of the unit. Refer to the diagram above.

n If the previous unit is the MASTER, then the other end of the cable connects to the

“Master Input / Slave Output” port of the MASTER (such as cable 1 in the diagram
above)

n If the previous unit is a slave, then the other end goes to the “Slave Input” port of

the previous slave unit (such as cable 2 and 3 in the diagram above)

l Upon connecting the daisy-chain cable to the previous unit, it should automatically

power up if the previous unit is powered up. However, it is still recommended that the
power supply be used with the slave unit. You will see the LED display on the front
panel show the units bank address setting.

INSTALLATION

l RESET the MASTER unit by pressing the Bank/SCAN and Channel buttons

simultaneously. This is necessary for the MASTER unit to detect the newly added
slave unit.

l Verify that the MASTER unit has detected the new slave by pressing the Bank/SCAN

button. If it detected the new slave properly, the LED display on the MASTER will
register the slave unit’s bank address. If you have many slave units, you may have to
press the Bank/SCAN button many times to cycle through all of the preexisting slave
units before reaching the newly added unit.

l Now you can power up the computers connected to the newly added salve unit. After

all the computers have booted up, you may need to RESET the MASTER unit again to
detect the presence of powered computers on the new slave unit.

CHAPTER 3.

OPERATION

Selecting which computer to operate can be done either by On -Screen Display, the select
button, or through keyboard “Hot Key” commands. You will notice that after the DKVM-8
switches to another computer, the mouse will be inoperative for about 1-2 seconds. This
is normal operation and ensures that proper mouse synchronization is established.

Pressing the “Channel” button cycles you through all the ports, including inactive ports.

Keyboard “Hot Key” Commands

latest version from your hardware manufacturer.

?If you are using a specialized mouse such as a cordless mouse, scrolling mouse or

mice with more than 2 operational buttons, use generic PS/2 mouse drivers.
Non-standard mice often use non -PS/2 proprietary mouse protocol.

?Make sure you do not have any mouse drivers loaded in your config.sys or

autoexec.bat files.
?Avoid moving the mouse or pressing the mouse buttons when switching ports.
?Reset the mouse to resume proper mouse movement simply by unplugging the

mouse form the front of the DKVM-8 for about 2-3 seconds, and plugging it in again.

D-Link Systems, Inc.

Subject to the terms and conditions set forth herein, D-Link Systems, Inc. (“D-Link”) provides this Limited Warranty:

• Only to the person or entity that originally purchased the product from D-Link or its authorized reseller or distributor, and

• Only for products purchased and delivered within the fifty states of the United States, the District of Columbia, U.S. Possessions or Protectorates, U.S.

Military Installations, or addresses with an APO or FPO.

Limited Warranty: D-Link warrants that the hardware portion of the D-Link product described below (“Hardware”) will be free from material defects in
workmanship and materials under normal use from the date of original retail purchase of the product, for the period set forth below (“Warranty Period”), except
as otherwise stated herein.

• Hardware (excluding power supplies and fans): One (1) year

• Power supplies and fans: One (1) year

• Spare parts and spare kits: Ninety (90) days

The customer's sole and exclusive remedy and the entire liability of D-Link and its suppliers under this Limited Warranty will be, at D-Link’s option, to repair or
replace the defective Hardware during the Warranty Period at no charge to the original owner or to refund the actual purchase price paid. Any repair or
replacement will be rendered by D-Link at an Authorized D-Link Service Office. The replacement hardware need not be new or have an identical make, model
or part. D-Link may, at its option, replace the defective Hardware or any part thereof with any reconditioned product that D-Link reasonably determines is
substantially equivalent (or superior) in all material respects to the defective Hardware. Repaired or replacement hardware will be warranted for the remainder
of the original Warranty Period or ninety (90) days, whichever is longer, and is subject to the same limitations and exclusions. If a material defect is incapable
of correction, or if D-Link determines that it is not practical to repair or replace the defective Hardware, the actual price paid by the original purchaser for the
defective Hardware will be refunded by D-Link upon return to D-Link of the defective Hardware. All Hardware or part thereof that is replaced by D-Link, or for
which the purchase price is refunded, shall become the property of D-Link upon replacement or refund.

Limited Software Warranty: D-Link warrants that the software portion of the product (“Software”) will substantially conform to D-Link’s then current functional
specifications for the Software, as set forth in the applicable documentation, from the date of original retail purchase of the Software for a period of ninety (90)
days (“Software Warranty Period”), provided that the Software is properly installed on approved hardware and operated as contemplated in its documentation.
D-Link further warrants that, during the Software Warranty Period, the magnetic media on which D-Link delivers the Software will be free of physical defects.
The customer's sole and exclusive remedy and the entire liability of D-Link and its suppliers under this Limited Warranty will be, at D-Link’s option, to replace
the non-conforming Software (or defective media) with software that substantially conforms to D-Link’s functional specifications for the Software or to refund
the portion of the actual purchase price paid that is attributable to the Software. Except as otherwise agreed by D-Link in writing, the replacement Software is
provided only to the original licensee, and is subject to the terms and conditions of the license granted by D-Link for the Software. Replacement Software will
be warranted for the remainder of the original Warranty Period and is subject to the same limitations and exclusions. If a material non-conformance is
incapable of correction, or if D-Link determines in its sole discretion that it is not practical to replace the non-conforming Software, the price paid by the original
licensee for the non-conforming Software will be refunded by D-Link; provided that the non-conforming Software (and all copies thereof) is first returned to D­Link. The license granted respecting any Software for which a refund is given automatically terminates.

Non-Applicability of Warranty: The Limited Warranty provided hereunder for Hardware and Software portions of D-Link's products will not be applied to and
does not cover any refurbished product and any product purchased through the inventory clearance or liquidation sale or other sales in which D-Link, the
sellers, or the liquidators expressly disclaim their warranty obligation pertaining to the product and in that case, the product is being sold "As-Is" without any
warranty whatsoever including, without limitation, the Limited Warranty as described herein, notwithstanding anything stated herein to the contrary.

Submitting A Claim: The customer shall return the product to the original purchase point based on its return policy. In case the return policy period has
expired and the product is within warranty, the customer shall submit a claim to D-Link as outlined below:

• The customer must submit with the product as part of the claim a written description of the Hardware defect or Software nonconformance in sufficient
detail to allow D-Link to confirm the same, along with proof of purchase of the product (such as a copy of the dated purchase invoice for the product) if the
product is not registered.

• The customer must obtain a Case ID Number from D-Link Technical Support at 1-877-453-5465, who will attempt to assist the customer in resolving any
suspected defects with the product. If the product is considered defective, the customer must obtain a Return Material Authorization (“RMA”) number by
completing the RMA form and entering the assigned Case ID Number at https://rma.dlink.com/

• After an RMA number is issued, the defective product must be packaged securely in the original or other suitable shipping package to ensure that it will
not be damaged in transit, and the RMA number must be prominently marked on the outside of the package. Do not include any manuals or accessories
in the shipping package. D-Link will only replace the defective portion of the product and will not ship back any accessories.

• The customer is responsible for all in-bound shipping charges to D-Link. No Cash on Delivery (“COD”) is allowed. Products sent COD will either be
rejected by D-Link or become the property of D-Link. Products shall be fully insured by the customer and shipped to D-Link Systems, Inc., 17595 Mt.
Herrmann, Fountain Valley, CA 92708. D-Link will not be held responsible for any packages that are lost in transit to D-Link. The repaired or replaced
packages will be shipped to the customer via UPS Ground or any common carrier selected by D-Link. Return shipping charges shall be prepaid by D­Link if you use an address in the United States, otherwise we will ship the product to you freight collect. Expedited shipping is available upon request and
provided shipping charges are prepaid by the customer.

D-Link may reject or return any product that is not packaged and shipped in strict compliance with the foregoing requirements, or for which an RMA number is
not visible from the outside of the package. The product owner agrees to pay D-Link’s reasonable handling and return shipping charges for any product that is
not packaged and shipped in accordance with the foregoing requirements, or that is determined by D-Link not to be defective or non-conforming.

What Is Not Covered: The Limited Warranty provided herein by D-Link does not cover: Products that, in D-Link’s judgment, have been subjected to abuse,
accident, alteration, modification, tampering, negligence, misuse, faulty installation, lack of reasonable care, repair or service in any way that is not
contemplated in the documentation for the product, or if the model or serial number has been altered, tampered with, defaced or removed; Initial installation,
installation and removal of the product for repair, and shipping costs; Operational adjustments covered in the operating manual for the product, and normal
maintenance; Damage that occurs in shipment, due to act of God, failures due to power surge, and cosmetic damage; Any hardware, software, firmware or
other products or services provided by anyone other than D-Link; and Products that have been purchased from inventory clearance or liquidation sales or
other sales in which D-Link, the sellers, or the liquidators expressly disclaim their warranty obligation pertaining to the product. While necessary maintenance
or repairs on your Product can be performed by any company, we recommend that you use only an Authorized D-Link Service Office. Improper or incorrectly
performed maintenance or repair voids this Limited Warranty.

WARRANTY OF ANY KIND WHATSOEVER INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE AND NON-INFRINGEMENT. IF ANY IMPLIED WARRANTY CANNOT BE DISCLAIMED IN ANY TERRITORY WHERE A
