Video Reference Frequency
This parameter sets the operating video frame rate of the hardware for all video channels in Mira Server. Selecting some
frame rates will disable some “Video Resolution” radio buttons, because those combinations are invalid. Likewise, selecting
other frame rates will enable some “Video Resolution” radio buttons, because those combinations are valid.
Video Resolution
This parameter sets the operating video resolution of the hardware for all video channels in Mira Server. If the video resolution
parameter you want is grayed-out an unavailable for selection, the first select the “
Video Reference Frequency
” radio button
for the desired format; and the “Video Resolution” radio button will then become active and available.
Video Reference Source
This parameter selects the operating output reference of the hardware for all video channels in Mira Server.
IMPORTANT NOTE:
Using the “
Free Run
” setting is recommended only for the Mira 4-Channel server, and only when that
Mira server is operating as a “stand-alone” device, with no video interconnect to any other external equipment.
IMPORTANT NOTE:
Failure to supply an external reference signal (Bi-Level or Tri-Level) to the Mira 8-Channel server will
eventually result in corrupted video on all video outputs. It is critical to supply an external reference signal!
IMPORTANT NOTE:
When using “
Tri-Level External Reference
” you must double-terminate with a 75-ohm terminator the
Tri-Level reference signal. This is best done with a BNC “T” connector and the 75-ohm terminator.
3G Serial
This parameter selects whether a “VK”, “VV” or “3D” channel pair operates as “Dual-Link 1.5Gb/s” or as “Single-Link 3.0Gb/s”
with Level B protocol.
The 3G parameter is available only in HD video formats (720 and 1080); and will only apply to those video channels
configured with channel pairing, including: “VK / VV / 3D” channel configurations. With “3G” selected, the lower-order channel
in the channel pair will carry the single-link 3Gb/s video signal. For example, when ChA and ChC are paired together, then the
3Gb/s video signal connects only with ChA.
