VL-SVN511BX/VL-SVN511CX/VL-SVN511CX1 1 Safety Precautions 1.1. Safety Precautions 1. Before servicing, unplug the power cord to prevent an electrical shock. 2. When replacing parts, use only manufacturer’s recommended components for safety. 3. Check the condition of power cord. Replace if wear or damage is evident.
VL-SVN511BX/VL-SVN511CX/VL-SVN511CX1 2 Warning 2.1. About Lead Free Solder (PbF: Pb free) Note: In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that con- tains lead. We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin, (Sn), Silver, (Ag), and Copper, (Cu).
VL-SVN511BX/VL-SVN511CX/VL-SVN511CX1 2.2. Insulation Resistance Test 1. Unplug the AC power cord and short the two prongs of the plug with a jumper wire. 2. Measure the resistance value with ohmmeter between the jumpered AC plug and all the terminals as shown in following figures.

VL-SVN511BX/VL-SVN511CX/VL-SVN511CX1 4 Technical Descriptions 4.1. What is a Video Intercom? 4.2. Video Intercom 4.2.1. Block Diagram Here is the block diagram of Video intercom system in Fig 1.1. The image data is converted into NTSC signal by Camera Unit. The NTSC signal is modulated into FM, then transferred to the Monitor station through the interphone cable.
VL-SVN511BX/VL-SVN511CX/VL-SVN511CX1 4.2.2. Cmos Image Sensor Unit Block Cmos image sensor unit and DSP blocks are shown in Fig. 1.2. Basically the image through the lens is converted into the elec- tric signal by the optical filter and cmos image sensor. Then it is transferred to the DSP block.
VL-SVN511BX/VL-SVN511CX/VL-SVN511CX1 4.2.7. Voice The voice from the microphone of Door station is amplified and sent to the Monitor station through 2-4 wire conversion circuit, DC blocking capacitor, transformer and interphone cable. The visitor’s voice is passed through the separation transformer, DC blocking capacitor, 2-4 wire conversion circuit and amplifier, and the voice can be heard through the speaker of the Monitor station.
