2. Camera Setup
2.1 Basic Camera Setup
For basic camera setup, as shown in Figure 1, one UM-100/UM-101 camera, one standard C-mount lens, one TV
monitor, one PS-12C power supplyunit or equivalent, and one BNC cable (75Ω) 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 Setup
A basic camera and frame grabber systemsetup, as shown in Figure 2 below, requires a UM-100/UM-101
camera, a standard C-mount lens, a PS-12C power supply, a PC systemand VGA monitor, a frame grabber or
interface card, and an external trigger device ifnecessary.

3. Camera Functions
3.1 12-Pin Connector
The 12-pin Hirose connector is located on the rear
plate ofthe 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. ApplyTTL signal on HD (pin # 6) and VD
(pin # 7) inputs ifnecessary, see section 4.1 for
details. Figure 3 belowshows a top viewofthe 12-
pin Hirose connector.

3.2 Shutter Speed Dial Switch
Shutter speed dial switch is located on the rear
panel (Figure 4). For normal shutter speeds, 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.

3.3 Normal and Asynchronous Capture
Mode (NRM/ASM)
NRM/ASM switch is located on camera rear plate.
Figure 5 shows all mode switch selections.
For normal operation, either with or without shutter
speed, NRM should be selected.
This camera DOES NOTprovide asynchronous
capture feature.

3.4 Gain Control Mode (AGC/MGC)
Automatic gain control (AGC):
AGC/MGC switch is located on the rear plate.
AGC factorysetting is 2V for AGC control and 3V for AGC MAX control. Therefore, the maximumgain 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 from5dB to 18dB through the gain potentiometer on rear plate.
Note: 32dB gain can be obtained through custom orders.
Figure 6. AGC and AGC MAX Control Characteristics
3.5 Gamma 1.0 and 0.45 Mode
1.0/0.45 mode switch is located on rear plate. Gamma is the numerical value ofthe degree ofcontrast in a
television picture. Gamma correction is the systemresponse modification byproviding linear transfer
characteristic fromthe input to output. In general, circuit built into a TV camera to compensate for non-linearity
that exists in displaytubes. Ifthe camera is connected directlyto 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 whygamma 1.0 is chosen for machine
vision applications. Gamma 0.45 is preferred when seeing video at lowlight level, which is common for
inspection byhuman eyes.
Figure 7. Gamma 1.0 and 0.45 Characteristics

3.6 Field and Frame Mode (FLD/FRM)
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 sensitivityin field mode is double for each field scanning (1/60 second). For anymoving image capture, field
mode is recommended in order to avoid the smearing phenomenon. However, the resolution is onlyone field, not
full frame resolution.
Frame Mode:
In frame mode, everyother horizontal line is scanned out; this is different fromfield 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 second period.
Both odd and even field combined will forma full frame, a period of1/30 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 disable.

4. Timing Signals
4.1 External Synchronization and Gen lock
The UM-100/UM-101 camera automaticallylocks to the external sync source. The external sync source must
match the camera HD and VD specification, which are 15.73KHzand 59.94Hzrespectively. Both external HD
and VD are TTL level signals.
a) HD
H: 2.5V to 5V
L: 0V or GND
Pulse width: 5-50% dutycycle, see figure 10 shown below.
b) VD
H: 2.5V to 5V
L: 0V or GND
Pulse width: 0.5-50% dutycycles; must be RS-170 format (odd and even fields).
Figure 9. External Synchronization and Gen lockTiming
4.2 Integration
The UM-100/UM-101 camera can be integrated up to 2 seconds without severe noise or darkcurrent effect.
Make sure the camera is set to frame mode before preceding anyintegration; this will ensure that there will be a
full frame video (both odd and even field). To start integration, pin #11 ofthe 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 backto
high or 5V level, as shown in figure 10 below. Ifa frame grabber does not capture the immediate two fields or
integrated video, the normal video (before the integration) will displayagain on the monitor.
Figure 10. Integration Control Timing

4.3 Strobe
Set NRM/ASM switch to ASM mode and make sure the FRM/FLD switch on rear panel is set to FRM mode in
order to achieve full frame resolution. The strobe application is similar to high-speed shutter application except
the strobe pulse must occur in the darkand no shutter is required. The advantage to use strobe is that a full
frame resolution ofvideo will be obtained. This will not happen when high-speed shutter is applied; a progressive
scan or full frame CCD camera must be utilized. The relationship between external VD and strobe pulse signal is
shown in figure 10 below. Make sure to fire strobe pulse between 1H and 8H when internal VD is at 0V or GND,
where 1H = 63.5µsec. After strobe pulse is fired, camera will output onlytwo vertical sync signals. The two sync
signals allowthe user to capture the following valid fields. Therefore, the camera will not have anyvertical sync
or video ifthere is no reset pulse on external VD pinout.

5. Camera Malfunction
WARNING: DO NOTATTEMPTTO OPEN THE CAMERAHOUSING FOR TROUBLESHOOTING IN ANY
CASE WITHOUTTHE CONSENTOF THE FACTORY.
Camera malfunction rarelyhappens. In case camera malfunctions, the following troubleshooting procedures
would help to minimize the problem; it definitelyhelps the user to find out the actual problemand maysave a trip
for sending the camera backto the factory.
First ofall, disconnect the 12-pin Hirose power connector and BNC cable fromthe camera unit. Make sure there
is nothing connected to the camera at this time.
Checkthe 12V DC power supplyat 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 backto 0 position and NRM/ASM to NRM location.
Ifframe 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 blankor bright displayshould be seen on
the TV monitor. Covering the CCD camera with hand or lens cap should see a darkvideo. Ifno video occurs,
most likelythe CCD camera is damaged. Consult the technical support at the factory.
Ifthere is video but it is not clean or bad, it is possible that the CCD imager glass is dirtybecause ofthe dirt on
CCD glass surface or the CCD camera is partiallydamaged. Use high-pressure air to blowthe dirt awayifthe
CCD glass is not clean. Ifthe problemstill exists, contact the UNIQ technical support for help.
Ifthere is video on TV monitor but not with a frame grabber, most likelythe problemis fromthe frame grabber's
software or hardware. Consult the frame grabber factoryfor further details. Ifa lens is used, make sure the iris is
wide open.
