Section 3 - Installation
Before Installation
Unpacking the Product
Before opening the product sealed packaging inspect the seal condition to
assure that product was not accessed or tampered during delivery. If
packaging seal looks suspicious contact Belkin support team and do not
use the product.
After seal removal inspect packaging content to verify that required
components included. See packaging content list in page 3 above.
After the Belkin Secure Windowing KVM is removed from its packaging
inspect the tampering-evident label to assure that product is properly
sealed. If the label is damaged or missing contact Belkin support and do
not use that product.
Where to locate the Belkin Secure Windowing KVM?
The enclosure of the product is designed for desktop or under the table
configurations. An optional Mount Kit is available.
Product must be located in a secure and well protected environment to
prevent potential attacker access.
If longer set of cables or if a Secure Fiber Extender (RFE) are used, the
Belkin Secure Windowing KVM may be remotely located in a locked down
facility to prevent unauthorized users access.
Consider the following when deciding where to place the Belkin Secure
Windowing KVM:
•User access to the front panel push-buttons is typically not
required as all user controls available through the mouse and
indications available on screen.
•Keyboard and mouse cables length. Cables typically may be
extended to a distance of 4.6 meters (15 feet).
•Display cable length. Typically may be extended to around 10
meters without video quality degradation (still depends on display
and cables quality and must be tested prior to fixed installation).
•The location of the computers in relation to the KVM and the
length of available KVM cables (typically 1.8 m)
Note: Due to USB and DVI signal limitations, the KVM cable length cannot
exceed 4.6 m (15 feet) unless an active extender is used.
Warning: Avoid placing cables near fluorescent lights, air-conditioning
equipment, RF equipment or machines that create electrical noise (e.g.,
vacuum cleaners).

Display selection considerations
Proper selection of user display is critical for the success of any Windowing
KVM deployment. The information provided here represents the
information gained in Belkin during evaluation and deployment projects.
•Avoid using old CRT displays.
•Some projects invested significant resources in the overall project
design and implementation but neglected the display and
peripherals. Users may reject the new system if proper display not
used with the system. As large LCD cost going down daily, it
become easier and cheaper to retrofit the user desktop
completely during these projects.
•Proper size of the display is critical. To enable simultaneous work
with several windows LCD panels larger than 22” diagonal are
recommended.
•Try to use the larger LCD size possible (taking the user workstation
/ table size into consideration).
•Check if the display adjusts automatically to resolution changes.
This feature is essential to support window maximization.
•Native resolution of the display should match output resolutions
supported by the Belkin Secure Windowing KVM.
•Display should support DVI input. HDMI can be used with proper
DVI to HDMI cable or adapter. In this case check audio out
channels cannot be routed through HDMI.
•It is recommended to involve the users in the display selection
process during evaluation and initial deployments.
•Consult Belkin support with specific display models and technical
specifications.
•DVI-I to VGA converters cannot be used with the Belkin Secure
Windowing KVM as it does not support analog video.
Dual Display Model 204M
•The 204M uses two displays. It is preferable that both displays will
be the same type and model.
•Displays must be landscape oriented and installed side by side in
close proximity to one another. Primary on the left and secondary
on the right side.
•Displays must be either 1920 x 1080 or 1920 x 1200 native
resolution.
DisplayPort Model 104Y
•Use DisplayPort 1.1 or 1.2 capable displays.
•Conversion from DisplayPort to DVI is not recommended due to
video quality loss.
•Some older displays may cause long delays when switching
between normal view mode and full screen mode.
