CHAPTER 2: PRODUCT OVERVIEW

Video
Video of 24-bit color depth up to a resolution of 1280 x 1024 at 60 Hz is supported by
the Black Box ServSwitch Extender. Both CRT and flat-panel LCD monitors are
supported, and can be connected to the Black Box ServSwitch Extender via
a DVI-I video
connector. For the Black Box Extender VGA monitors can be attached to the system by
using a DVI to VGA adaptor. The system supports DDC version
2B.
The DTX5002 Extender supports video of 24-bit color depth up to a resolution of
1920x1200 at 60 Hz. At the transmitter only DVI-D PC video sources are supported.
However, as DVI-I is supported at the receiver a VGA adapter can be used to connect to
a
VGA monitor.
Screen aspect ratio
The transmitter can be configured through the serial console to allow either normal aspect
resolutions or wide screen resolutions as the preferred setting on its EDID table.
Bandwidth usage (DTX5000 only)
It is possible to restrict the aggregate bandwidth used on the Ethernet link from the serial
console. The bandwidth options are:
• Unlimited
• 100MBits/s
• 50MBits/s
• 20MBits/s
• 10MBits/s
Reduced Total Cost of Ownership (TCO)
The Black Box ServSwitch Extender delivers significantly lower TCO when compared to
traditional distributed computer systems. Centralized maintenance enables greater security
and convenience as well as reduced workplace disruption and down-time.
IT
administration costs are also significantly reduced by housing all PCs in one central
location. Relocating the computer away from the user frees up valuable office space and
reduces desktop power and heating, ventilation and air conditioning (HVAC)
requirements.
2.3 Safety Precautions
To avoid potential video and/or keyboard problems when using Black Box products:
• If the building has 3-phase AC power, ensure that the computer and monitor are on
the same phase. For best results, they should be on the same circuit.
To avoid potentially fatal shock hazard and possible damage to equipment, please observe
the following precautions:
• Do not use a 2-wire extension cord in any Black Box product configuration.
• Test AC outlets at the computer and monitor for proper polarity and grounding.
• Use only with grounded outlets at both the computer and monitor. When using
a backup Uninterruptible Power Supply (UPS), power the computer and the
transmitter off the same supply.
NOTE:
The AC inlet is the main disconnect.
