2.2 SINGLE 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 areSLAVE 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.

2.4 DAISY-CHAIN
The DKVM-8 can be daisy-chained with additional DKVM-8 units through the DB-25
daisy-chain ports. The daisy-chain cable is required (not included) for proper operation.
Please refer to the example below. Here, four DKVM-8 units are cascaded together for
control over 32 computers. Recall that a maximum of 16 DKVM-8 units can be cascaded
together for control over 128 computers. Recall that the DIP-switch on the MASTER unit
must be set to BANK 0, and the SLAVE units set to a unique BANK (any from 1 through
F). See the beginning of this section for more information on the DIP-switch settings.
lAfter 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.
lUsing the daisy-chain cable, connect one end to the “Master Input / Slave Output” port
of the unit. Refer to the diagram above.
nIf 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)
nIf 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 3in the diagram above)
lUpon 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.

lRESET the MASTER unit by pressing the Bank/SCAN and Channel buttons
simultaneously. This is necessary for the MASTER unit to detect the newly added
slaveunit.
lVerify 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.
lNow 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.

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
You can also conveniently command the DKVM-8 to switch ports (channel) through
simple keyboard key sequences. To send commands to the DKVM-8, the SCROLL
LOCK key must be pressed twice within 2 seconds. You will hear a beep for
confirmation. Below are the different commands.

You can switch directly to any channel by giving the DKVM-8 the BANK and Channel
numbers. For instance, if you press SCROLL LOCK, SCROLL LOCK, 2, 5, the computer
onchannel 5 of DKVM-8 set to BANK 2 will be selected. In the following diagram, that is
PC 21. Hence, if you only have one DKVM-8, the first key (X) must be “0”.
AutoScan Mode
In AutoScan mode, DKVM-8 remains on one channel for a number of seconds, before
switching to the next. This time interval is set in the On-Screen Display menu.
Note: There is no mouse or keyboard control in this mode. This is necessary to prevent
errors. Otherwise, if the user is moving the mouse or using the keyboard when
DKVM-8 switches to the next channel, data flow is interrupted and will cause erratic
mouse movement and / or the wrong characters to show up when using the
keyboard.
To get out of AutoScan mode, press the SPACE BAR.
