(E)
USB 2.0 Ports
These ports are used to connect to an external Hi-Speed USB 2.0 portable disk drive or memory stick. Data transfer rates up to
800Mb/s are possible. Typically, this port is used to transfer clip file data between the Mira server and the portable disk drive.
NOTE:
Any portable disk drive or memory stick connected to this USB port must be formatted for use on Windows O/S. Portable disk drives or memory
sticks formatted for exclusive use on the Mac O/S will not operate properly.
(F)
USB QWERTY Keyboard
The included USB QWERTY Keyboard (or any USB compatible keyboard) is connected to this port. The QWERTY keyboard
must be connected to this port in order to properly operate the Mira server.
(G)
USB
Mouse
The included USB Mouse (or any USB compatible mouse) is connected to this port. The mouse must be connected to this port in
order to properly operate the Mira server.
(H)
Gigabit Ethernet Port
This port is used to connect the Mira server to a local area network (LAN). Typically, this port is used to transfer clip file data
between the Mira server and the LAN. This port is capable of gigabit performance, and is backward compatible with older 10-T
and 100-T Ethernet networks.
When multiple Mira servers are installed, these Ethernet ports can be used to manage all the clip content on the multiple Mira
servers.
(I)
System Reference Input
This BNC connector must be supplied with house Bi-Level analog reference or Tri-Level analog reference. If this input signal is
missing, then video/audio outputs from the Mira server will not be synchronized with external video/audio equipment.
If Tri-Level reference is used, then an external 75-ohm terminator with a BNC “T” connector must be employed in order to
double-terminate the Tri-Level reference signal feeding Mira.
(J)
Quad Viewer Output
This BNC connector provides an HD-SDI serial digital video output of the built-in quad-split viewer, which is used to monitor the
second group of four video channels ChA-ChD. This HD-SDI output can only connect to an external picture monitor capable of
accepting 1.5Gb/s HD-SDI digital video input. Each of the four “panes” in the quad-split viewer also contains the timecode and
title of the clips loaded in the four video output channels.
NOTE:
The Quad Viewer only appears when Mira is operating in HD video formats, 720 or 1080. The Quad Viewer output is
disabled
when Mira is
operating in SD video formats, 525 or 625. If you will be operating Mira in standard definition, then please use the desktop Viewer that is built into the Mira
Explorer user interface instead of this Quad Viewer.
(K)
Analog LTC I/O
These two BNC connectors provide input and output for the analog longitudinal timecode (LTC) signal, which is used as system
reference timecode. When recording clips, the timecode data present on this port is also recorded on the “External Timecode”
track inside the clip.
(L)
Disk RAID-6 Maintenance Only!
This 100/T Ethernet port is only used for a dedicated maintenance terminal for the internal media RAID-6 disk array. This port
should
never
be used as a “general” Ethernet port for file transfer and clip management. Alternatively, the RAID-6 disk array
maintenance can be performed through a web browser via the main gigabit Ethernet port [item (H) on page 20 above].
(M)
Main GUI DVI-D Output
This output displays the main graphical user interface (GUI) of the Mira server, and connects to an external computer monitor
with a DVI-D port. For optimum user experience, this external computer monitor should feature a minimum resolution of
1280x1024. Monitors with higher resolution are also acceptable and encouraged, in order to provide more “screen real estate” for
users.
