Separate control unit
Both the BVM-20EIE/20EIU/l0FIE/20EIU and
BVM-14EIE/14EIU/14FIE/14FIU are controlled by
a separate control unit, such as a BKM-IOR Monitor
Control Unit. Use of a separate control unit reduces
the space needed for the equipment. With the BVM-
20EIE/20EIU/l0FIE/20FI U, it is also possible to
attach the BKM-IORwith an optional BKM-32H
Monitor Control Unit Attachment Kit
Data exchange between monitors
Up to 32 units of theBVM-20EIE/20EIU/lOFIE/
20FIU andBVM-14EIE/14EIU/14FIE/14FIU can be
connected via serial remote connectors and controlled
by a single BKM-IORMonitor Control Unit or By a
single BVM-14E5E/14E5U/14F5E/14F5U Color
Video Monitor which contains integrated control units.
By copying memory card data and transmitting data
through the serial remote connector, it is possible to
share adjustment and setup condition data between the
monitors.
Controlling monitor groups
Up to 32 monitors can becontrolled from the BVM-
14E5E/14E5U/14F5U/14F5U. First, using the monitor
menus,assigna monitor address numberto each
monitor, divide the monitors into groups, and assign a
group number to each group. Then you can use the
BVM-14E5E/14E5U/l4F5U/14F5U to control
individual monitors or monitor groups simply by
entering monitoraddressor group numbers.You can
also execute the same operation on all connected
monitors, or use the BVM- l4E5E/l 4E5U/14F5U/
14F5U to put all connected monitors into thesame
setup and adjustment state.
Setup and adjustment with the monitor
memory card
You can use an optional BKM-12Y Monitor Memory
Card to save and load monitor setup and adjustment
data. If your system includes more than one monitor,
you can use the monitor memory cards to exchange
data between monitors. This makes it easy to put all
monitors in your system into the same setup and
adjustment state.
Standard auto alignment system
Decoder chroma and phase adjustment, as well as
color temperature control, may be performed with the
auto alignment system. This makes ii possible to
coordinate settings among multiple monitors.
Expandable input capability
The input connector configuration may beeasily
modified by simply sliding optional decoder adaptors
or input expansion adaptors into input option slots at
the rear of the monitor. The BVM-14E5E/14E5U/
14F5E/14F5U/lOE IE/20E IUll0FIE/20FI U may be
fitted with up to four adaptors, and the BVM-14EIE/
14EIU/14FIE/14FIU will accept two.
4:3/16:9 dual aspect ratio design
The monitors can be changed to either 4:3 or 16:9
aspect ratios with jusl a simple switching operation
from an optional monitor control unil such as a BKM-
IOR. The screen can be also changed lo 4:3 or 16:9
display by the replacement of a mask (no tools
required).
Stable color temperature
The internal beam current feedback circuit maintains a
constant color temperature over long periods of time.
Blue-only mode convenient for monitoring
noise
All three CRT cathodes can be driven with a blue
signal, producing a monochrome display. This mode
is convenient for chroma and phase adjustment, and
for monitoring V1R noise.
Menu operation
The monitor's various functions and operating
conditionscan be set with on-screen menus. Menu
operations are performed using an optional monitor
control unit such as a BKM- IOR.

When installing the adaptors, be sure to perform the
necessary input signal setup with the INPUT
CONFIGURATION menu. If the setup is not
performed, the adaptors may not function correctly.

Decoder Adaptor Priority
1be table on the right shows which decoder adaptor
will be selected preferentially when morethan one
decoder adaptor which can accept the NTSCor PAL
signal format have been installed in the monitor.
For example, when a BKM-24Nand a BKM-27Tare
installedand an NTSCsignal is selected, the NTSC
signal connected to the BKM-24N's input connectors
and the NTSC signal connected to the BKM-27T's
input connectors are both processedby the decoder on
