Cautionary notes about Monitor

・There are two types of monitors of NTSC standard and of PAL standard as is the case with camera. Use the

NTSC standard monitor for this camera.

・Never use a monitor like a coaxial superimposed type monitor that generates a DC voltage on a Video input

terminal. It causes the camera to malfunction.

・It is recommended to use a monitor of which the horizontal resolution is 600 TV lines or larger.

Cautionary notes about Power supply
(Please fully observe following precautions when using
a power supply other than our DC-12NI power supply.)

・Be sure to use a constant voltage power supply rated at 12VDC±10%, 250mA or larger.
・Use the included DC plug and if it is necessary to make wire connection make it as shown by

the right diagram without a single mistake.

・Be sure to avoid contact of DC jack terminals with each other.

● If you do not follow the above precautions, it may cause a break down of the camera or

power supply or else it may trigger a fire.

● Please be sure to check that all the equipments are turned off prior to connecting with external

devices.

1) Please take off a lens cap of TMC-734D and mount a lens.(screw-in system)

・When using C mount lens, use our C mount adaptor (CR-5,option) together.
・Please check the lens specification again when the lens do not fit in the lens mount well.

2) Connect the iris control cable of the camera to ④AUTO IRIS connector of TMC-734D when
using an auto iris lens.

Adjustment of Iris level (only for DC auto iris lens)

Adjust the iris level using ⑤IRIS level adjust knob on the side panel to make the brightness of the
object to the right level.
In case of the lens other than DC auto iris lens, the operation of this IRIS level adjust knob is invalid.

3) Insert the DC plug into the POWER connector on the rear panel.

・Be sure to turn the power off before connecting DC plug.
・It is recommended to use our DC-12NI power supply (12VDC,450mA, option).

4) Connect ⑦VIDEO OUT terminal of TMC-734D to the monitor via 75 ohm cable such as 3C2V or

5C2V. if the monitor has S-terminal, the higher resolution images can be obtained by connecting it
to ⑧Y/C output terminal. Concurrent use of ⑦VIDEO OUT and ⑧Y/C output terminal is
possible.

6

5) Turn on TMC-734D, monitor and connected device etc..

Adjusting method of Lens mount position

・Mount the lens used and loosen all three hex-head screws③.
・Move the lens mount back and forth and focus a camera on the far point with the lens focus of infinite distance.
・Tighten all three hex-head screws at the point where it comes into focus.

Cautionary notes about Electronic shutter

・Smear may appear when the intense light falls onto the CCD imaging area in E.I(Electronic iris) and high speed

shutter mode. (it is not the camera-related failure.)

・The flickering phenomennon may occur at commercial power frequency in the lighting environment such as

fluorescent lamp or mercury lamp. If the phenomenon gets to a serious extent, use the camera with ⑭Shutter
switch turned OFF.(In this case, it is recommended to concurrently use Auto iris lens.)
A high-frequency lighting may also contribute to reduce the phenomenon.

・The flickerless function(F.L) is the effective function to reduce a perceptible flicker. It is effective only at 50Hz

commercial frequency area for NTSC standard monitor.

Cautionary notes about White balance mode

・AUTO tracking mode(AUTO) or Push-lock white balance mode(P.W.B) is efficient way to take a white balance

under the luminous surroundings where it is difficult to take a white balance in the preset mode (Light bulb mode,
Fluorescent light mode1, Fluorescent light mode2).

・It is effective to employ AUTO tracking mode(AUTO) where the lighting environment varies with time

(cf.around-the-clock monitoring) However a white balance may not properly be taken under the luminous
surroundings where the amount of light is extremely low or the flicker emission is very high.

・Adjustment of white balance in P.W.B mode is more efficient by doing it while capturing the white object and

displaying it in full-screen.

・In P.W.B mode, a white balance can be set in most luminous surroundings but it has not the function to auto

tracking the variation of luminous surrounding.(It is needed to manipulate a W/B adjust button(B) in each case.)

● Immediately turn off all the equipments and recheck the connection if nothing appears on a

monitor screen.

6) Adjust the aperture and the focus of the lens while watching the screen image of the monitor..

・Adjust the lens mount position in the following way if it has difficulty in focusing (e.g., by using

non-standard lens).

7) Select the electronic shutter speed to suit the intended use by the⑭shutter switch as needed.

8) Select the white balance mode to suit the intended use by the⑩W.B selector switch as needed.

7

9) Turn the Backlight correction function ON with ⑬-3 BLC on/off switch as needed.

Cautionary notes about Back light correction function

・Back light correction is the function to reduce so-called “blocked up shadows” which may occur in underexposure

condition.

・There are three ways of Backlight correction as follows according to ⑭Shutter switch setting.

Setting

Way of making Back light correction

E.I

To make a Backlight correction with a combination of Shutter switch adjustment and AGC operation.

F.L

To make a Backlight correction only with AGC operation.(Shutter switch is fixed.)

OFF
1/250
1/500
1/1000
1/2000
1/4000

・To make a Backlight correction by varying a control signal level of ④AUTO IRIS connector.
(In backlit state,the backlight correction is made lowering the Iris signal level)
Therefore the backlightr correction is made only when the Auto iris lens is used together.
・AGC operation may have effect opposite to Backlight correction based on the condition of the
object. In this case,turn the AGC ON/OFF switch to OFF.

Cautionary notes about Function setting SW

・It may be more effective to reconfigure the function taking “intended purpose”,“status of use” and “picture

quality”etc. into consideration
