1. OUTLINE
This series color monitors have the input systems suited to
the diversified system needs. In addition to 3 video input
systems, au RGB input system or a YPoPn input system is
provided as a stand ard equipmen t. A Dl, D2 or D3 input
syste m (2 serial inpu t systems and 1 parallel input
system) or a Y/ C inpu t system can be provided as
an optiona l equipment, RGB and YPnPn can be
corresponded to various standard s and you can adjust the
chroma level by front pane l. When the optional decoder
board (P AL or SECAM) is inserted into the SLOT section
in add ition to NTSC decoder board, this monitor can be
made automatic ally to operate with 2 format signals. Thus
this product is the maste r monitor for the professional
with the various functions, fine performa nce and stability
which is corresponded to various broadcasting system and
used for the final check of th e video signal.
2. FEATURES
(1) High-performanceinline GunCRT
This monitor uses an iuline gun dot mask high-deta il
CRT. The dot mask pitch is a fine 0.31 mm for the
TM14-20RH / RP , 0.43 mm for th e TM20-20RH/ RP,
and 0.28 mm for the TM20-30RH/ RP.
Since the CRT for the 20 series (the same CRT as f9r
the 15 and 19 series) coats bismuth oxide (BiO) on
the shadow mask and th e 30 series uses inver material
for the shadow mask mat erial, th e doming (beam
displacement due to thermal deformation of th e
shadow mask) when the brilliance is raised is greatly
reduced.
(2) DigitalControl
Control is completely digitized with an 8-bit MPU
and 10-bit D/ A converter . Therefore, various status
displays are possible and aut o setup 'can be carried
out by j ust adding the probe. Since control uses
rotary encoders, you can adjust with the same feeling
as with the analog contr ollers you have used up till
now.
(3) Auto Setup Function
The optional ASP-15 auto setup probe can be used to
automat ically adjust the factory setting color
tem perature . Also, if you hav e the probe memorize
the operator's unique color temper ature, then you can
automati cally set any number of monitors (15 series,
18 series, 20 series, 30 series) to that color
temperat ure.
(4) 4 ColorTemperaturescan he StoredInto Memory
This monitor can store three color temperatures in
addition to the factory setting. This means you can
quickly and easily select the whit e balance sett ing
best for th e state of the input image and the usage
objective .
(5) RemoteControlFunction
In addition to the standard parallel remote connector,
there are also an opt ional infrared wireless remote
controller(RCT-2 0) and an optiona l *serial control
box that can use a loop through connection with a
BNC cable.
Any single one of these remote contro llers can control
up to 99 monitors.
* ..· mad e-to-order
(6) BeamFeedbackSystem(BFS)
The beam feedback system, which detec ts the CRT
cathode current, provides images with stab le white
balanc e for a long time.
(7) Built-inCCDCombFilter(only NTSC )
The CCD lH-delay line greatl y improves the cross
luminance and the cross color. Also, the optional
Faroudja comb decoder provi des an image with no
cross luminance in the section with no vertical
relationship.
(8) SufficientInputSystems
Th ere are four inpu t system s, thr ee composite video
input and one RGB or Y/ PB/Pn (Y/ B-Y/R -Y) input.
(Th e lat ter can be switched between RGB and Y/
Pa/Pa with the pull-out panel ~peration section.)
Optio ns are 8/ 10-bit digital (Dl , D2, D3) input and
Y/ C input. In addition , th e DC301 dual component
board can be used for 2-chann el component input .
(9) Built-inGenerators
Five different types of test signals (cross hatch, flat
field, window, chara cter, and step wave with pluge
signal) and you can switch the output format between
525 (60 Hz)and 625 (50 Hz) with simple menu
operations. Safe title signals (80%, 85%, 90%, 95%,
100%, 80+90+100 %, 5-partition cross hatch, and 10-
partition cross hat ch) are built in as sta ndard features .
(10) VideoBoardModularization
Th e video syste m boards are plug-in type. To make
repairs and checks easier, the video, def(lection), and
power boards can be removed with the monitor itself
still in its rack.

(11) Component Input that Meets Various Standards
In order to meet such standards as M Il, Beta, N-10,
and SMPTE, R-Y and B-Y levels relative to the Y
level can be adjusted freely with the CHROMA
manual contr ol on the front pan el and by just
setting the standard to use with the pull-out panel,
you can automatically switch the chroma preset level.
The chroma level can also be adjusted freely for RGB
signals.
(12) Handles All Three Formats: NTSC/PAL/SECAM
In addition to the standard decoder board, a variety
of option decoder boards can be mounted in slots to
automatically monitor composite signals in all three
formats , NTSC/PAL/SECAM on a single monitor.
Also, since the deflection system is adjusted to be able
to handle 525 (60 Hz) and 625 (50 Hz) formats with
the standard configuratio n, if the signals are analog
component signals (RGB, Y/ Pn/Pn) or digital
component signals (Dl ), you can monitor signals in
almost any format without a decoder board .
(13) Digital Input
Digital input can be corresponded to parallel and
serial inputs for Dl, D2 or D3. The circuit treats by
10 bit. You can switch to 8 bit or 10 bit by front
panel operation . Because of using the filter built-in
x/S IN x correction based on the 601 of the CCIR
recommendations in post filter, the faithful converting
digital int o analog is possible.
(14) V/VS (0%/7 .5% set up) Function
The V/VS function is the function to switch ·the
clamp level (black level) of the monitor in
conformity to the set up level (0% or 7.5%) of input
signal. Because the V/VS setting can be set with
each channel by menu operation, if the set up level of
selected signal is changed, keeping the black level
fixed is possible .

the safe action area.
· Since the 95% frame is the same size as for over scan,
you can set the over scan size if you adjust the screen
size so that the escutcheon frame and the 95% frame
match.
· The 100% frame can be used for H. phase adjustment .
For details on the adjustment method, see 5-4.(8).
You can also visually check the video blanking width
and check the input signal video phases.
· 5-partition cross hatch and 10-partition cross hatch
can be used to set the position of the camera location.
@!COMBlSwitch
For composite video input, when the NTSC decoder
board is selected(NTSC mode), pressing this switch
lights up the LED and uses a CCD comb filter circuit
for luminance signal and chroma signal separation.
When the LED is off, a trap circuit is used.
The CCD comb filter circuit eliminates the drop in
resolution when the color signals are reproduced.
When the optional Faroudja comb decoder board
(DE305) is used, this comb circuit is always used and
separatio n does not switch to the trap circuit .
@!S-PALISwitch
For composite video input , when the PAL-B decoder
boa.rd is selected(function does not work when the
PAL/SECAM decoder board or PAL-M decoder board
is selected), pressing this switch lights up the LED
and makes the demodulation simple PAL. When th e
LED is off, the demodulation is delay PAL.

j does not use a. delay line. It simply converts the
. modulation output to light as is. In other words, it
Iuses the average effect of the human eye and
· alternates every other scanning line between + and
I-to eliminate the color phase error. . _ . _ . _ .
@!SCREENS!Switch
These switches switch the R/G/B screens on/off.
There are two modes for the!SCREENSlswitches . For
details on the setting method , see 5-6.(6). When all
the screens are "ON", the LEDs are all "OFF".
