Referring to the illustrations in Figure 2 and Figure 3 on the previous page above:
(A)
AC Power #1 In
Input #1 for mains power into the dual-redundant power supply. The power supply is auto-sensing with an input AC voltage
range of 100VAC to 240VAC at 47Hz to 63Hz. If only one mains power cord is plugged in, the power supply alarm will sound
when Mira is powered on. Either plug in the second AC power cord or press the
POWER SUPPLY ALARM MUTE
button (located to
the immediate right of the PSU’s) to silence the alarm.
NOTE:
Some versions of the Mira power supply do
not offer an “Alarm Mute” button. You must plug in the second power
cord to silence the alarm.
(B)
AC Power #2 In
Input #2 for mains power into the dual-redundant power supply. The power supply is auto-sensing with an input AC voltage
range of 100VAC to 240VAC at 47Hz to 63Hz. If only one mains power cord is plugged in, the power supply alarm will sound
when Mira is powered on. Either plug in the second AC power cord or press the
POWER SUPPLY ALARM MUTE
button (located to
the immediate right of the PSU’s) to silence the alarm.
NOTE:
Some versions of the Mira power supply do
not offer an “Alarm Mute” button. You must pl
ug in the second power cord to silence the alarm.
(C)
RS422 Ports
This 64-Pin-D connector attaches to a breakout cable (supplied with Mira) which has eight RJ45 connectors at the other end.
When connected to the Mira 4-Channel server, the first four RJ45 connectors at the end of this breakout cable provide RS422
serial control ports for the four video channels: ChA, ChB, ChC and ChD.
When connected to the Mira 8-Channel server, all eight RJ45 connectors at the end of this breakout cable provide RS422 serial
control ports for all video channels: ChA, ChB, ChC, ChD, ChE, ChF, ChG and ChH.
These RS422 serial control ports are used to control the video/audio channels of the Mira server from external controllers
capable of RS422 serial control, and which support either “Sony BVW-75”, “Odetics” and/or “Louth VDCP” protocols.
Each video channel in Mira features an RS422 serial control port, located through a break-out cable on the rear panel of the Mira
Server. At the end of the breakout cable are “Ethernet” type RJ45 connectors. Mira includes adapters for each RS422 serial port
to convert the RJ45 cable to 9D, so you can just plug a standard male 9D serial cable into the adapter.
These RJ45 cables for the RS422 serial ports are each wired 1:1 from the eight pins of the RJ45 to the first eight of the nine pins
in standard “D9” serial RS422 cables. A given installation of the Mira server may require use of the RJ45-to-D9 adapter
connector if RS422 serial control is routed via D9 connection.
These RS422 serial ports are used to control the video/audio channels of the Mira server from external controllers capable of
RS422 serial control, and which support either “Sony BVW-75,” “Odetics,” or “Louth VDCP” protocols.
(D)
Analog Time of Day LTC IN
This XLR connector provides input for an analog longitudinal timecode (LTC) signal, which is typically used as “time of day” or
“house” timecode. When recording clips into Mira, the user may specify this timecode input signal as the timecode source, which
is then recorded into the timecode track within the clip.
(E)
USB
QWERTY Keyboard
A USB QWERTY Keyboard or USB Mouse can be connected to this port.
(F)
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.
(G)
eSATA-II Ports
These ports are used to connect to an external eSATA-II portable disk drive. Data transfer rates up to 3.0Gb/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 connected to this eSATA-II port must be formatted for use on a Windows O/S. Portable disk drives formatted for exclusive
use on the Mac O/S will not operate properly.
