1. Introduction

1.1 General Description

The USS-300/USS-301 series is an automatic exposure control (electronic shutter) camera using near infrared

(NIR) CCD imager. The camera is four times more sensitive than the conventional CCD camera at 945 nm wavelength. Smear is significantly reduced and dynamic range is much greater than the conventional CCD cameras. The camera works very well between low light and sunlight conditions. The high gain circuitry provides clear video quality at low light condition. In a daylight condition, the camera will automatically covert the saturated incoming light source into a constant viewable video level with its auto electronic shutter control.

2. Camera Setup

2.1 Basic Camera Setup

For basic camera setup, as shown in Figure 1, one USS-300/USS-301 camera, one standard C-mount lens, one

TV monitor, one PS-12C power supply unit or equivalent, and one BNC cable (75

) are required. Make sure the camera has the correct settings before powering up. See section 3 for details.

Figure 1. Basic Camera Setup

2.2 Camera and Frame Grabber System Setups

A basic camera and frame grabber system setup, as shown in Figure 2 below, requires a USS-300/USS-301 camera, a standard C-mount lens, a PS-12C power supply, a PC system and VGA monitor, a frame grabber or interface card, and an external trigger device if necessary.

3. Camera Functions

3.1 12-Pin Connector

The 12-pin Hirose connector is located on the rear plate of the camera. All ground signals on pin # 1, 3,

5, 8, 10, and 12 are common grounds. Although

+12 V DC input is recommended on pin #2, this camera should withstand +12 V

±

1V input voltage.

Make sure to set the NRM/ASM switch to NRM position on rear plate for external HD and VD locking. Apply TTL signal on HD (pin # 6) and VD

(pin # 7) inputs if necessary, refer to section 4 for details. Figure 3 below shows a top view of the 12pin Hirose connector.

3.3 Shutter Speed Dial Switch

Shutter speed dial switch is located on the rear panel (Figure 5). The camera default setting is at

ASM. For normal shutter speed, it has 9 different shutter speeds to select from. Position # 0 is standard scanning speed, 1/60 second. As “Position

#” goes higher, the shutter speed goes higher and the video becomes darker.

The camera default setting is in ASM mode. To disable the default setting (auto electronic shutter mode), switch to NRM.

3.5 Gain Control Mode (AGC/MGC)

Automatic gain control (AGC):

AGC/MGC switch is located on the rear plate.

AGC factory setting is 2V for AGC control and 3V for AGC MAX control. Therefore, the maximum gain is about

18dB as shown in Figure 6 below. AGC setting cannot be changed through the rear gain potentiometer.

Manual gain control (MGC):

The manual gain control can be adjusted from 5dB to 18dB through the gain potentiometer on rear plate. 32dB gain can be obtained through custom orders.

Figure 6. AGC and AGC MAX Control Characteristics

3.6 Gamma 1.0 and 0.45 Mode

Gamma is the numerical value of the degree of contrast in a television picture. Gamma correction is the system response modification by providing linear transfer characteristic from the input to output. In general, circuit built into a TV camera to compensate for non-linearity that exists in display tubes. If the camera is connected directly to a frame grabber, it is desired to set to Gamma 1.0. For direct connection to a TV monitor, gamma 0.45 is recommended, since TV monitor has a non-linear correction. In general, gamma 0.45 is noisier than gamma 1.0, which is why gamma 1.0 is chosen for machine vision applications. Gamma 0.45 is preferred when seeing video at low light level, which is common for inspection by human eyes.

Figure 7. Gamma 1.0 and 0.45 Characteristics

3.7 Field and Frame Mode (FLD/FRM)

6

Field Mode:

Field/Frame mode switch is located on the rear panel. In field mode, two adjacent horizontal lines are combined and scanned out as shown in figure 8 shown below. There is one line offset between odd field and even field.

The sensitivity in field mode is double for each field scanning (1/60 second). For any moving image capture, field mode is recommended in order to avoid the smearing phenomenon. However, the resolution is only one field, not full frame resolution.

Frame Mode:

In frame mode, every other horizontal line is scanned out; this is different from field mode as described above.

For odd field, line 1 is scanned out first. For even field, line 2 is scanned first. Each field has 1/30 sec. period.

Both odd and even field combined will form a full frame, a period of 1/30 second. For strobe, long-term integration, and non-moving image capturing, frame mode is recommended. In order to obtain a full frame image, a frame grabber must be applied to capture the image. It's difficult to distinguish the difference between field mode and frame mode on a standard TV monitor. In frame mode, shutter function is disabled .

4. Timing Signals

4.1 External Synchronization and Gen-lock

When the camera is in NRM mode, the USS-300/USS-301 camera automatically locks to the external sync source. The external sync source must match the camera HD and VD specification, which are 15.734KHz and

59.94Hz respectively. Both external HD and VD are TTL level signals. a) HD

H:

L:

2.5V to 5V

0V or GND

Pulse width: 5-50% duty cycle, see figure 10 shown below. b) VD

H: 2.5V to 5V

L: 0V or GND

Pulse width: 0.5-50% duty cycle; must be RS-170 format (odd and even fields).

Figure 11. External Synchronization and Gen-lock Timing

4.2 Integration

The USS-300/USS-301 camera can be integrated up to 2 seconds without severe noise or dark current effect.

Make sure the camera is set to NRM and FRM before preceding any integration; this will ensure that there will be a full frame video (both odd and even field). To start integration, pin #11 of the 12-pin connector must be connected to GND or 0V. The integrated video will be shifted out following the next vertical drive after pin #11 goes back to high or 5V level, as shown in figure 11 below. If a frame grabber does not capture the immediate two fields or integrated video, the normal video (before the integration) will display again on the monitor.

5. Camera Malfunction

WARNING: DO NOT ATTEMPT TO OPEN THE CAMERA HOUSING IN ANY CASE WITHOUT CONSENTING

THE FACTORY.

Camera malfunction rarely happens. In case camera malfunctions, the following troubleshooting procedures would help to minimize the problem; it definitely helps the user to find out the actual problem and may save a trip for sending the camera back to the factory.

First of all, disconnect the 12-pin Hirose power connector and BNC cable from the camera unit. Make sure there is nothing connected to the camera at this time.

Check the 12V DC power supply at the 12-pin connector cable and make sure it does provide the right voltage to the 12-pin connector.

Make sure to set the camera shutter dial switch back to 0 position and NRM/ASM to NRM location.

If frame grabber was connected to the camera, disconnect it.

Now, power up the camera, and connect it to a TV monitor with a BNC cable. Make sure the monitor and BNC cable are good. Point the camera at a bright scene without a lens on, a blank or bright display should be seen on the TV monitor. Covering the CCD camera with hand or lens cap should see a dark video. If no video occurs, most likely the CCD camera is damaged. Consult the technical support at the factory.

If there is video but it is not clean or bad, it is possible that the CCD imager glass is dirty because of the dirt on

CCD glass surface or the CCD camera is partially damaged. Use high-pressure air to blow the dirt away if the

CCD glass is not clean. If the problem still exists, contact the UNIQ technical support for help.

If there is video on TV monitor but not with a frame grabber, most likely the problem is from the frame grabber's software or hardware. Consult the frame grabber factory for further details. If a lens is used, make sure the iris is wide open.
