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 supply unit or equivalent, and one BNC cable (75W) 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 system setup, 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 system and VGA monitor, a frame grabber or  
interface card, and an external trigger device if necessary.

Note  
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, see section 4.1 for  
details. Figure 3 below shows a top view of the 12-  
pin Hirose connector.

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 NOT provide asynchronous  
capture feature.

3.4 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.  
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 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.

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 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 second 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 disable.

4. Timing Signals  
4.1 External Synchronization and Gen lock  
The UM-100/UM-101 camera automatically locks to the external sync source. The external sync source must  
match the camera HD and VD specification, which are 15.73KHz and 59.94Hz respectively. Both external HD  
and VD are TTL level signals.  
a) HD  
H:  
2.5V to 5V  
L:  
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 cycles; must be RS-170 format (odd and even fields).  
Figure 9. External Synchronization and Gen lock Timing  
4.2 Integration  
The UM-100/UM-101 camera can be integrated up to 2 seconds without severe noise or dark current effect.  
Make sure the camera is set to frame mode 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 10 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.  
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 dark and no shutter is required. The advantage to use strobe is that a full  
frame resolution of video 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 = 63.5msec. After strobe pulse is fired, camera will output only two vertical sync signals. The two sync  
signals allow the user to capture the following valid fields. Therefore, the camera will not have any vertical sync  
or video if there is no reset pulse on external VD pinout.

5. Camera Malfunction  
WARNING: DO NOT ATTEMPT TO OPEN THE CAMERA HOUSING FOR TROUBLESHOOTING IN ANY  
CASE WITHOUT THE CONSENT OF 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.
