Anleitung Zusammenfassung
The WJ-SQ208 is a 8-input switcher. This sequential switcher has a video output of sequential and spot. The sequential output displays each camera in sequence : front panel indicators show which camera in sequence is being displayed. The spot monitor output permits manual selection of any camera for display on a second monitor ; when not used, this output automatically becomes sequential.Any camera switched to the 'Spot monitor" position is stilt included in the switching sequence. A bypass switch allows any camera to be bypassed from the switching sequence. This sequential switcher also has vertical interval switching for glitch free switching among synchronized cameras. The length of time each camera is displayed during the sequence is manually adjustable from 1 to 30 seconds. 1. Video output of sequential and spot. 2. Front panel indicators show which camera is being displayed. 3. Spot output for manual selection of any camera for display on a second monitor. 4. Spot output : when not used, automatically becomes sequential. 5. Any camera switched to the spot monitor position is still included in the switching sequence. 6. Bypass switch skips any camera from sequence. 7. Vertical interval switching for glitch free switching picture among synchronized cameras. 8. Switching interval manually adjustable from 1 to 30 seconds. 9. Loop-through video connector with automatic termination is provided. PRECAUTIONS • Do not attempt to disassemble the instrument. In order to prevent electric shock, do not remove screws or covers. There are no user-serviceable parts inside. Do refer all servicing to qualified service personnel. • Do not abuse the instrument. Avoid striking, shaking, etc. It could be damaged by improper handling or storage. Do handle the instrument with care. • Do not use strong or abrasive detergents when cleaning the instrument body. Do use a dry cloth to clean the instrument when dirty. In case the dirt is hard to remove, use mild detergent and wipe gently. • Do not expose the instrument to water or moisture, and do not operate in wet area. Do take immediate action if ever the instrument does become wet. Disconnect the power cord and refer servicing to qualified service personnel. Moisture can damage the instrument and also create the danger of electric shock. • Be sure to disconnect the AC Adaptor from the AC outlet while this sequential switcher is not used. • All necessary procedures with regard to the installation of this product should be made by qualified service personnel or system installers. • Do not use the instrument in an extreme environment where high temperature or high humidity exist. Use the instrument under conditions where temperatures are within 14°F - 122°F (-10°C - +50°C), and humidity is below 95%. MAJOR OPERATING CONTROLS AND THEIR FUNCTIONS 1. Time Control (S/L) The sequential switcher’s timing can be continuously changed from approx. 1 to 30 seconds by turning this control. 2. Sequence Output Indicators (1/2/3/4/5/6/7/8) A lit lamp indicates that the signals of the corresponding camera are available at the Camera Output Connector. 3. 3-position Selection Switches (BYPASS/AUTO/SPOT MON) a) b) c) BYPASS • AUTO • SPOT MON • a) BYPASS mode When this switch is set to the BYPASS position, the camera signal in this position will be skipped regardless of the presence of a video signal while the other camera signals will be fed out in sequence. In other words, the signal of that camera will not be fed out of Spot/ Sequential Output Connector (6). This function may be very convenient in cases where monitoring requirements vary from time to time. -2- b) AUTO mode When the switch is set to this position, the signal of the camera will be automatically in sequence regardless of the presence of a video signal from that source. c) SPOT mode When the switch is set to this position, the signal of the camera in that position will be output from the Sequential/Spot Output Connector (6) so that this camera signal can be selectively monitored. During this time, sequence operation goes on and sequence outputs are fed out from the Sequential/Spot Output Connector (6). If two or more cameras are set in this mode, the signal of the lower numbered camera in this position will be used as output signal. 4. Camera Input Connectors (CAMERA IN) These are used to connect the video output signals from cameras. When connected, the signals will be terminated at 75 ohms. 5. Camera Output Connectors (CAMERA OUT) The video input signals connected to the Camera Input Connectors (8) are looped through to these connectors. BYPASS AUTO SPOT MON 6. Sequential/Spot Output Connector (SPOT/SEQ 7. Adaptor Connector (DC 9V) OUT) Connect an AC adaptor (supplied) to this connector. This is a sequential switcher output connector which always produces sequence outputs. SYSTEM CONNECTION Caution: Keep the power switches all units in the OFF position during connections. SPECIFICA...
