1. Introduction 1.1 General Description The UM-100/UM-101 series is a low cost, high resolution, and standard EIA/CCIR CCD camera. It provides excellent image quality with super HAD, on-chip micro lens and blemish free CCD imager. Different shutter speed can be changed through rotary switch located on rear plate. AGC/MGC, Gamma 1.0/0.45, and Frame/Field mode selections are also available on the rear plate. A 12-pin Hirose connector provides power, HD/VD signals, and video output fo

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 (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 system setup, as shown in Figure 2 below, req

3. Camera Functions 3.1 12-Pin Connector Pin No. Description Note The 12-pin Hirose connector is located on the rear 1 GND plate of the camera. All ground signals on pin # 1, 3, 2 +12V DC input 5, 8, 10, and 12 are common grounds. Although 3 GND +12 V DC input is recommended on pin #2, this 4 Video camera should withstand +12 V ± 1V input voltage. 5 GND 6 External HD TTL Make sure to set the NRM/ASM switch to NRM 7 External VD/Strobe TTL position on rear plate for ex

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 thr

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 fie

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;

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
