7.3.3 Multi-Display Installation
The B024-DPU08 and B024-DPU16 multi-display feature allows you to stack up to 8 units in a dual/triple/quad-
display/multi-displayinstallationtocontroluptoseven(B024-DPU08)orfteen(B024-DPU16)computersatonce.

exibilityformultiple-monitorinstallationswhereeachcomputerisequippedwithmultiplevideocards.
Note: In a multi-display installation, the B024-DPU08 can only be connected to B024-DPU08 units, and the B024-DPU16 can
only be connected to B024-DPU16 units.
1Use a standard USB Type-A to USB Type-B cable to connect the Port 8 USB Type-B port on the First Stage
unit to the USB Type-A port in the Console Ports Section of the second switch.
Notes:
• Port 8 is reserved to connect the units in a multi-display installation. Up to seven (B024-DPU08) or fteen (B024-DPU16)
computers can be attached, using KVM ports 1–7 (B024-DPU08) or ports 1–7/9–16 (B024-DPU16).
• Plug the USB Type-A connector into the lower USB (keyboard) Port in the Console Port Section. Both USB Ports are
marked with a similar icon to remind you of the correct USB port.
2Use DisplayPort cables to connect the KVM’s DisplayPort on the second unit to the second video-in port on the
computers.
Note: Only DisplayPort video cables are necessary–all other ports in the KVM section are not required in this installation.
3Connect a display to the console section of the second switch.
4Repeat steps 1-3 for any additional units for a total of up to a total of 8 switches.

Note: Make sure the computers and devices connected to the KVMs are also properly grounded.
7.3.4 Grouping Ports into Vertical Channels
Once the cables have been connected and multi-display mode has been selected in the OSD, the KVM will auto-
detect the channels and display modes. Users can then assign them a channel number as the port name so all the
Port 1s become Channel 1, all the Port 2s become Channel 2, ... , and all the Port 7s become Channel 7. The ports
will all be switched at the same time, channel by channel.
Dependingonthenumberofstagesinyourstack,theKVMinstallationo󰀨ersdualdisplay(twostages),tripledisplay
(three stages), quad display (four stages) or multi-display (up to 8 stages) scenarios. For reference purposes, the
example below shows a four-stage installation with quad display functionality.
