3.4 Warranty

The warranty period is 36 months. The terms and conditions valid at the signing of the contract apply.

 Notes on operating the camera

  • The camera can be operated at 12 V DC or 24 V AC.
  • The DF 2000A was designed for use with CS-mount lenses. An adapter

ring is required for use with C-mount lenses. Note the lens type before

using it. When using C-mount lenses without an adapter ring, the

camera could be damaged. This applies especially for the sensors.

  • Lenses with DC control can be used for automatic iris control. Video

signal-controlled lenses are not supported.

  • If the camera or the cable connected to the cable is located near

sources of strong radiation, the video picture may be distorted.

  • The camera is equipped with automatic gain control (AGC). In low

light the picture may be altered (e.g. noise). This is not a camera


  • The quality of the video picture depends on the lens used, the lighting

and the monitor used to display the video picture.

  • Automatic white balance depends on the lighting used and can cause

color distortions in artificial light.

  • Poor lighting can lead to faulty white balance.

5. Equipment and connections

DF 2000A


1. Lens mount and back focus adjustment

The lens mount (threaded ring) is suitable for holding CS lenses.

The threaded ring is also used to set the back focus (back focus

Chapter: Setting the back focus).

2. Setting screw

FSetting screw (2 mm Allen screw) for loosening/locking the threaded

ring when setting the back focus (back focus Section: Setting

the back focus).

3. 1/4" thread insert

A 1/4" thread insert is located above and below for mounting the

camera to a tripod, a wall mount etc.

!Only use screws with a max. length of 7 mm for mounting.

Longer screws could damage the amera.

DF 2000A

DF 2000A

4. Video signal output (Video OUT)

A composite video signal (CVBS) is output at the BNC jack. The signal complies with either the PAL or the NTSC standard, depending on the signal system setting.

5. Operating voltage display

The LED illuminates when the camera is supplied with power.

6. Connection for iris control

Control voltage for automatic iris control on lenses with DC control isnavailable at this connection.

!Check the plug for correct contact assignment (see table) before connecting the lens.

DF 2000A

7. Selector

The selector is used for menu selection and to set the corresponding parameters.

8. Set button

Press the Set button in normal operation at least 2 seconds to display the camera menu.

Once the camera menu is displayed, a specific menu item or setting is activated when the Set button is pressed.

9. Power supply connection

The camera can be operated at 12 V DC or 24 V AC.

Connect the cable for power supply to the screw terminals 9 of the camera.

DF 2000A

!You must ensure correct polarity of the cable when using 12 V DC. Use insulated cables. The cables for power supply may not contact the housing of the camera.

! If used in North America, note the following: You must use a UL-certified, limited-power Class 2 power supply unit (12 V DC / 0.42 A or 24 V AC / 0.20 A) for the camera power supply.

10. RS232c interface

A PT can be controlled via the RS232c (pin 1). The PT is controlled via the video cable by using UTC. For control via UTC, you require a recording system with the UTC function from the DMS/DLS product series.

Check for correct contact assignment.

PIN4 = RX input of camera

PIN3 = ground

PIN2 = ground

PIN1 = TX output of camera for PT

DF 2000A

Customer-specific adaptation for control of the camera via the RS232c interface is available on request.

6. UTC Remote Box

The UTC Remote Box (accessory) is a special on-site aid. If the camera is already installed, it can be configured via the UTC Remote Box. Direct access to the camera, e.g. on a mast, is not necessary. The buttons on the box correspond to the Selector and the Set button on the camera in all functions.

The UTC Remote Box is installed on the video cable between the camera and the monitor or between the camera and the recorder.

DF 2000A

7. Connection and installation

7.1 Attaching the lens

!The length (a) of the lens thread (see following figure) plus any protruding parts may not exceed 5 mm, as otherwise the sensor could be damaged.

Check whether it is a CS-mount lens. If a C-mount lens is used, an appropriate adapter ring is to be used.

DF 2000A

!The camera is pre-configured for use with DC-controlled lenses. For lenses with manual iris setting, the configuration (Section 8.1 ) is to be changed accordingly.

! Ensure that dirt does not end up on the sensor. Use only clean compressed air if cleaning is necessary. Under no circumstances may liquids or cotton wool be used for cleaning.

Remove the protective cap from the lens mount. Screw the lens onto the camera without using force.

7.2 Setting the back focus

The back focus is the distance between the lens support on the camera and the picture sensor. Optimum focus is only possible when the correct distance is set.

It may be necessary to set the back focus in inpidual cases due to production tolerances of the lens.

The iris of the lens must be open as wide as possible (smallest iris value) to set the back focus. For lenses with automatic iris control, you will require an ND filter (gray filter)

to prevent the iris from closing in bright light.

Setting for lenses with a fixed focal distance

If the focus cannot be set exactly by turning the focus ring (lens), proceed as follows:

1) Point the camera at an object with sufficient contrast. The distance to

the object should be greater than 1,000 x the focal distance.

2) Open the iris on the lens.

3) Set the distance at the lens to infinity (∞).

4) Loosen the setting screw 2 on the camera with the accompanying hexagonal wrench.

5) Rotate the lens ring 1 until the optimum focus is achieved.

6) Tighten the setting screw again.

Setting for lenses with a variable focal distance (zoom)

If the focus changes as the focal distance changes, proceed as follows:

1) Point the camera at an object with sufficient contrast at a distance of approx. 2 m.

2) Open the iris on the lens.

3) Set the maximum focal distance (Tele) at the lens.

4) Set the optimum focus with the focus ring.

5) Set the smallest focal distance (wide angle).

6) Loosen the setting screw 2 on the camera.

7) Rotate the lens ring 1 until the optimum focus is obtained.

You may need to repeat Steps 3, 4, 5 and 7 several times to obtain the best results.

8) Tighten the setting screw 2 again.

8. Konfiguration

Use the Set button 8 and the Selector 7 to call up the menus and to set certain camera properties.
