1. Introduction
1.1General Description
The USS-300/USS-301 series is an automatic exposure control(electronic shutter)camera using nearinfrared
(NIR)CCD imager. The camera is fourtimes more sensitive than the conventionalCCD camera at 945 nm
wavelength. Smearissignificantly reduced and dynamic range is much greaterthan the conventionalCCD
cameras. The camera works very well between low light and sunlight conditions. The high gain circuitry provides
clearvideo quality at low light condition. In adaylight condition, thecamera will automatically covert the saturated
incoming light source into a constant viewable video levelwith its auto electronic shuttercontrol.

2. CameraSetup
2.1BasicCameraSetup
Forbasic camera setup, as shown in Figure 1, one USS-300/USS-301 camera, one standard C-mount lens, one
TV monitor, one PS-12C powersupply unit orequivalent, and one BNC cable(75Ω)arerequired. Make sure the
camera has the correct settings before powering up. See section 3 fordetails.
Figure 1. Basic Camera Setup
2.2Cameraand FrameGrabber System Setups
A basic camera and frame grabbersystemsetup, as shown in Figure 2 below, requires a USS-300/USS-301
camera, a standard C-mount lens, a PS-12C powersupply, a PC system and VGA monitor, a frame grabberor
interface card, and an externaltriggerdevice if necessary.

3. CameraFunctions
3.112-Pin Connector
The 12-pinHirose connectoris 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 recommendedon pin #2, this
camera should withstand +12 V ±1V input voltage.
Make sureto set the NRM/ASM switch to NRM
position on rearplate forexternalHD and VD
locking. Apply TTL signalon HD (pin # 6)and VD
(pin # 7)inputs if necessary, referto section 4 for
details. Figure 3 below shows a top view of the 12-
pin Hirose connector.

3.3Shutter SpeedDial Switch
Shutterspeed dialswitch is located on the rear
panel(Figure 5).The camera default setting is at
ASM. Fornormalshutterspeed, it has 9 different
shutterspeeds to select from.Position # 0 is
standard scanning speed, 1/60 second. As “Position
#”goes higher, the shutterspeed goes higherand
the video becomes darker.

The camera default setting is in ASM mode. To disable the default setting (auto electronic shuttermode), switch
to NRM.
3.5Gain Control Mode(AGC/MGC)
Automatic gain control (AGC):
AGC/MGC switch is located on the rearplate.
AGC factory setting is2V forAGC controland 3V forAGC MAX control. Therefore, the maximum gain is about
18dB as shown in Figure 6 below. AGC setting cannot be changed through the reargain potentiometer.
Manual gain control (MGC):
The manualgain controlcan be adjusted from 5dB to 18dB through the gain potentiometeron rear plate. 32dB
gain can be obtained through custom orders.

3.6Gamma1.0and 0.45 Mode
Gamma isthe numericalvalue of the degree of contrast in a television picture. Gamma correction is the system
response modification by providing lineartransfercharacteristic from the input to output. In general, circuit built
into a TV camera to compensatefornon-linearity that exists in display tubes. Ifthe camera is connected directly
to a frame grabber, it is desired to set to Gamma 1.0.Fordirect connection to a TV monitor, gamma 0.45 is
recommended, since TV monitorhas a non-linearcorrection. In general, gamma 0.45 is noisierthan gamma 1.0,
which is why gamma 1.0 is chosen formachine vision applications.Gamma 0.45 is preferred when seeing video
at low light level, which is common forinspection by human eyes.
Figure 7. Gamma 1.0 and 0.45 Characteristics
3.7Fieldand FrameMode(FLD/FRM)

Field Mode:
Field/Frame mode switch is located on the rearpanel. In field mode, two adjacent horizontallines are combined
and scanned out as shown in figure 8 shown below. There is oneline offset between odd field and even field.
The sensitivity in field mode is double foreach field scanning (1/60second). Forany moving image capture, field
mode is recommended in orderto avoid thesmearing phenomenon. However, the resolution is only one field, not
full frame resolution.
Frame Mode:
In frame mode, everyotherhorizontalline isscanned out; this is different fromfield mode as described above.
Forodd field, line 1 is scanned out first.Foreven field, line 2 is scanned first.Each field has 1/30 sec. period.
Both odd and even field combined willforma full frame, a period of 1/30 second. Forstrobe, long-term
integration,and non-moving image capturing, frame mode is recommended. In orderto obtain a fullframeimage,
a frame grabbermust be applied to capture the image. It's difficultto distinguish the difference between field
mode and frame mode on a standard TV monitor. In frame mode, shutterfunction is disabled.

4. Timing Signals
4.1External Synchronization and Gen-lock
When the camera is in NRM mode, the USS-300/USS-301 camera automatically locks to the externalsync
source. The externalsync source must match the camera HD andVD specification, which are 15.734KHz and
59.94Hz respectively. Both externalHD and VD are TTL levelsignals.
a)HD
H: 2.5V to 5V
L: 0V orGND
Pulse width:5-50% duty cycle, see figure 10 shown below.
b)VD
H: 2.5V to 5V
L: 0V orGND
Pulse width:0.5-50% duty cycle; must be RS-170 format (odd and even fields).
Figure 11. ExternalSynchronization and Gen-lock Timing
4.2Integration
The USS-300/USS-301 camera can be integrated up to 2 seconds without severe noise or dark current effect.
Make surethe camerais set to NRM and FRM before preceding any integration; this will ensure that there will be
a full framevideo (both odd and even field). To start integration, pin #11 of the 12-pin connectormust be
connected to GND or0V. The integrated video willbe shifted out following the next verticaldrive afterpin #11
goes back to high or5V level, as shown in figure 11 below. If a frame grabberdoes not capture the immediate
two fields orintegrated video, the normalvideo (before the integration)will display again on the monitor.

5. CameraMalfunction
WARNING:DO NOTATTEMPT TO OPEN THE CAMERA HOUSING IN ANY CASE WITHOUT CONSENTING
THE FACTORY.
Camera malfunction rarely happens. In case cameramalfunctions, the following troubleshooting procedures
would helpto minimize the problem; it definitely helps the userto find out the actualproblem and may save a trip
forsendingthe camera back to the factory.
First of all,disconnect the 12-pin Hirose powerconnectorand BNC cable from the camera unit. Make sure there
is nothing connected to the camera at this time.
Check the 12V DC powersupplyat the 12-pin connector cable andmake sureit does provide the right voltage to
the 12-pin connector.
Make sureto set the camera shutterdialswitch back to 0 position and NRM/ASM to NRM location.
If framegrabberwas connected to the camera, disconnect it.
Now, power up the camera, and connect it to a TV monitorwith a BNC cable.Make sure the monitorand BNC
cable are good. Point the cameraat a bright scene without a lens on, a blankorbright display should be seen on
the TV monitor. Covering the CCD camerawith hand or lens cap should see a dark video. If no video occurs,
most likely the CCD camera is damaged. Consult the technicalsupport at the factory.
If there is video but it is not clean orbad, it ispossible that the CCD imagerglass is dirty because of the dirt on
CCD glass surface orthe CCD camera is partially damaged. Use high-pressure airto blow the dirt away if the
CCD glass is not clean. Ifthe problem still exists, contact the UNIQ technicalsupport forhelp.
If there is video on TV monitorbutnot with a frame grabber, most likely the problem is from the frame grabber's
software orhardware. Consult the frame grabberfactory forfurtherdetails. If a lens is used, make sure the irisis
wide open.
