Operating Manual
Rev. 0.2 - Updated September 26, 2005

Precaution

• Handle the camera with care. Do not abuse the camera. Avoid striking or
shaking it. Improper handling or storage could damage the camera.

• Do not pull or damage camera cable.

• During camera use, do not wrap the camera unit in any material. This will
cause the internal temperature of the unit to increase.

• Do not operate camera in wet areas and do not expose camera to
moisture.

• Do not operate camera beyond its maximum operating temperature,
humidity and power source ratings.

• To prevent dust or contamination from entering the CCD or filter area,
which could scratch or damage this area, keep lens or lens cap on camera
when camera is not in use.

• Do not expose the camera to the following conditions:

- Wet, moist and/or high humidity areas

- Hot direct sunlight

- High temperature areas

- Near objects that release strong magnetic or electric fields

- Strong vibration

• When cleaning the camera, use a soft cloth to clean the external areas of
the camera. Use a pressured air spray to clean the surface of the glass.
Do not scratch the surface of the glass.

• Use only a REGULATED POWER SUPPLY and supply the power with the
specified voltage.

5. Variable Integration Shutter Trigger Operations

Note: Double Speed 2:1 Interlace mode is not used in these variable integration
shutter trigger operations.

Important: DIP Switch No. 5 must be turned ON and No. 6 must be turned OFF

when the camera operates in the “Variable Integration Shutter Trigger Mode”.

a) One Pulse Variable Integration Shutter Trigger Operations

I) Functions

With this “one-pulse Variable integration shutter trigger mode”, one
trigger pulse input signal can control camera’s integration time
based on its pulse duration time. In other words, the integration
time starts at the falling edge of the trigger oulse then ends at its
rising edge (see the drawing below). Since “XSUB” is activated in
the camera at the falling edge of the trigger pulse and “XSG” is
activated at the rising edge, the integration time is controlled very
accurately.

Video signal output is sent out frm the camera at the moment “t2” period
ends. “t2” starts at the rising edge of the trigger pulse and ends at the
18th internal HD pulse (2:1 Interlace Mode) or 33rd internal HD pulse
(Progressive Mode) after the rising edge of the trigger pulse. Therefore,
“t2” is exactly 19H (2: Interlace Mode) or 34H (Progressive Mode) if the
rising edge of the trigger oulse is synchronizing to the internal HD pulse.
In the case the rising edge of the trigger pulse is not synchronizing to the
internal HD pulse, this “t2” will fluctuate depending on the relational
timing of the two pulses as described in section 2.

This camera provides a capability to synchronize to External HD in the
variable integration shutter trigger mode. With this feature, user can
easily create HD-synchronized trigger pulse for the above mentioned
operation since the internal HD synchronizes to the external HD applied to
the camera.

II) Timing Chart

Note: Trigger input pulse must be positive (STC-1100C) or negative (STC-1100D)
enabled.

b) “T” - Integration period must be set within the following time length

Normal Speed Interlace: 100µmsec - 16.7msec
Normal Speed Progressive: 100µmsec - 16.7msec
Double Speed Progressive: 50µmsec - 8.3msec

c) “t1” - From the rising edge of the trigger pulse to the vertical sync pulse

Normal Speed Interlace: 4H + Td (19H with HD-synchronized trigger)
Normal Speed Progressive: 4H + Td (5H with HD-synchronized trigger)
Double Speed Progressive: 4H + Td (5H with HD-synchronized trigger)

d) “t2” - From the rising edge of the trigger pulse to the video out

Normal Speed Interlace: 18H + Td (19H with HD-synchronized trigger)
Normal Speed Progressive: 33H + Td (34H with HD-synchronized trigger)
Double Speed Progressive: 33H + Td (34H with HD-synchronized trigger)

e) Minimum trigger intervals are the following. Cycle speed of each trigger
must be greater than these values

Normal Speed Interlace: 18msec
Normal Speed Progressive: 36msec
Double Speed Progressive: 18msec

6. Vertical Reset Operations

In this “Vertical Reset Mode”, when the camera receives one VD pulse,
only one field of video signal (2:1 Interlace mode) or one frame of video
signal (progressive mode) is sent out.

1) Turn “Sync Mode Switch” (2.b) to “External Sync”

2) Turn DIP switch No. 2 (2:C:II) to “ON (Internal or External Sync)”. The

camera switches to external mode automatically when external HD is
supplied.

3) The vertical operates as “Direct Reset Mode”

4) In the case of 2:1 Interlace, even odd field is determined by the timing

of the falling edge of the vertical reset pulse (see note on next page)
