2.8.4. Signal outputs
MX-DVI-HDCP-OB cards provide 29-pole DVI connectors for output connections.
As with standard DVI outputs, the usable cable length is limited, since there is no
output amplification applied. For longer cable runs at the outputs, use fiber optical
extenders or active DVI repeaters/extenders.
MX-HDMI-OB cards provide 19-pole type A HDMI connectors for output
connections. Additionally to each HDMI output, an RCA jack connector is provided
with S/PDIF digital audio signal. Note that embedded audio is still present on HDMI
outputs.
Output reclocking
Each output signal is reclocked and stabilized. Signal reclocking is an essentially
important procedure in digital signal transmission. After passing the reclocker
circuit, the signal becomes stable and jitter-free, and can be transmitted over more
equipment like processors or event controllers. Without reclocking, sparkles, noise,
and jaggies can be seen on the image.
Fiber Cable powering
As a special feature, Pro series matrix switchers provide 500 mA current on +5V
output (pin 14 on DVI output connectors and pin 18 on HDMI output connectors )
which is sufficient to supply power to fiber optical DVI cables. Standard DVI outputs
or VGA cards only supply 55 mA current on +5V output, thus they are unable to
directly power a fiber optical cable.
2.8.5. Power connection
Plug a standard IEC power cord into this connector to connect the switcher to a
100 to 240 Volt AC, 50 Hz or 60 Hz power source.
