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.

DKVM-8, use the MASTER bank setting. If the DKVM-8 you are using will be
Daisy-Chained off another unit, use a unique slave setting. Please refer to the previous
section for more information. (NOTE: DIP-Switch No. 1 and 2 are reserved, default
setting is “ON”.)

to your computers and the DKVM-8.

INSTALLATION
~ 7~
Step 2
Find a convenient place to put your DKVM-8. Its 19” rack mount form factor makes it
ideal mountable on 19” rack. When mounting to a rack, attach the included brackets to
the sides of the DKVM-8. Take note of the length of your cables so that your computers,
DKVM-8, keyboard, mouse and monitor are distanced properly.
Step 3
Connect the monitor to the DKVM-8. Using the attached cable, or the one included with
your monitor, connect it to the HD DB-15 female port on the back of the DKVM-8 labeled
with the monitor symbol at the CONSOLEconnector.
Step 4
Connect the keyboard and mouse to the DKVM-8. If you have an AT type keyboard, you
will need an AT to PS/2 adapter.

the male end of the cable to the VGA port on the computer, and the female end on the
PC1 VGA port at the back of DKVM-8.
Step 6
Connect the first computer’s mouse cable to the DKVM-8. If using a PS/2 cable connect
one end to the PS/2 mouse port on the computer, and the other end to the PC1 PS/2
mouse port on the back of DKVM-8. If using a serial mouse cable connect one end to a
DB-9 serial port on the computer, and the other end to the PC1 DB-9 serial mouse port
on the back of the DKVM-8.
Step 7
Connect the first computer’s keyboard cable to the DKVM-8. Using another PS/2 cable
