Front panel card holders permit each input source to be labeled. For added flexibility, inputs can be Hi-Z looped or 75 ohm terminated (switchable) with BNC connectors. ■ FEATURES • Designed with solid state circuitry for reliability. • Excellent picture reproduction, with minimum crosstalk and low frequency transients. • Electronic, vertical interval switching. • Unterminated, loop-through video inputs; switchable for 75 ohms. • Illuminated, non-lock switch. • Card holder permits each input to be labeled. • Desk top and rackmount versions available. ■ PRECAUTIONS 1. Do not use the unit beyond its temperature, humidity or power source ratings. a) Designed for indoor use. Ambient temperature must not range beyond 14° F ~ 122° F (-10°C - +50°C). b) Avoid using the unit when humidity is above 90%. c) The input power source must be 120V AC 60Hz.

Front panel card holders permit each input source to be identified and labeled. (3) Video Input Connectors [VIDEO INPUT] There are two unterminated video input connectors for each channel, to allow loop-through hook-up. If looping through is not used, terminate the input with 75 ohm BNC Terminator Plugs, (not provided) © Video Output Connector [VIDEO OUTPUT] The single BNC connector contains the video signal from the selected input. © Power Cord ■ CARD LABELING 1. Write the camera position or number on the indication cards of standard accessory. 2. Pull off the covers of the Video Selecting Switches, place the indication cards and replace the covers. ■ CONNECTIONS t Video Input Connector • Video Input Connectors (§) The vertical interval switching of the unit is triggered by the vertical sync within Video Input No. 1. Therefore, to obtain vertical interval switching, a video signal must be connected to input No. 1, and all other video signals must be synchronized to that signal. All of the Video Input Connectors are unterminated. If looping through is not desired 75 ohm BNC Termination Plugs (not provided) should be used for termination. WIRING PRECAUTIONS: 1. Use 75£2 coaxial cable. 2. Never staple the cable — not even with circular staples. Do not bend coaxial cable into a curve whose radius is smaller than 10 times its diameter. Nev6r crush or pinch the cable. Any of these will change the impedance of the cable and cause poor picture quality. 5 - ■ SPECIFICATIONS Type Desk-top Rackmount Model No. WJ-220 WJ-225 WJ-220R WJ-225R Power Source 120V AC 60Hz Power Consumption Approx. 5W Video Input (I.OVp-p composite/75i2 or Hi-Z BNC) 6 12 6 12 Video Output O.OVp-p composite/75ii BNC) ONE Switch Non-lock illumination type Switching Electronic/vertical interval switching Crosstalk Better than 60dB {at 3.58MHz) Differential Gain Less than 0,5% (10% ~ 90% APL (average picture level)) Differential Phase Less than 0.5° (10% ~ 90% APL) Frequency Response 10MHz ±0.5dB Ambient Operating Temperature 14°F ~ 122°F <-10°C ~ +50°C) Ambient Operating Humidity Less than 90% Dimensions (W x H x D) 8%"x1%''x5Vi" 210x44x135(mm) 16Vi''xiy«"x5y.'' 420x44x1351 mm) 19"x1%”x5%" 480x44x135(mm) 19”x1%“x5%" 480x44x135(mm) Weight Approx. 3 lbs 1.4 kg Approx.
