3800+ Receiving Mainboard
YIJIA Electronics Co. ,Ltd , one of the EAS manufacturers as a senior in China, focus on research and technology development in EAS industry over the years, with the solid experience in EAS equipment installation, a variety of customer¡¯s use and feedback, has developed multiple first techniques in domestic EAS industry. These techniques have used in its several mainboards: 3800+, 3810+, 4800+ and 4810+. Details about the 3800+ mainboard performance:
A. Original functions from YIJIA Electronics 3800+ mainboard: 1. Active interfering signal independent LED indicator: using two flash lights LED3 and LED4 to show active interfering signal when making an installation, in order to facilitate on-site troubleshooting. 2. A converse power polarity protection and LED indicator: some customers had the mainboard broken when they made a converse power polarity, in view of this situation, adding a protection network is necessary. The mainboard has a LED that shows a converse power polarity, and the mainboard will be protected, the board will never broken by a converse power polarity. 3. A fault fuse LED indicator: if the fuse is broken, the LED beside will light up immediately. 4. Frequency independent power supply network: to ensure the stability of the frequency signals, and not to be affected by other components or the voltage fluctuations. 5. Anti-interference reinforcement selection: you can select the receiving board to resist more interfering signal by a Short Route JP4. 6. RFID(Radio Frequency Identification) anti-counterfeit code: with a unique RFID on each mainboard, it can be identified through the website.
B. Other functions: 1. Showing on-site interfering signal with three green LED lights DS1, DS2 and DS3, in order to facilitate on-site troubleshooting and to adjust the equipment. 2. PIF detection technology: extract the effective signal in the noise by the digital comb filter. 3. Using a Digital PLL(phase-locked loop) technology to reduce noise signal, improving the system's ability for resisting Co-channel interference. 4. Frequency dislocation technology: it¡¯s unnecessary to make a signal synchronization when straight-line distance¡Ý15 meters between two similar detection systems. It reduces a cost of synchronization cable, and has a convenience for the project implementation and installation. 5. Gate installation distance: in an ideal Electromagnetic environment, it has a 1.2 meters installation distance for soft label and 1.8 meters installation distance for tag. 6. Low power consumption, a simple appearance, a reliable performance, and a good on-site adaptability. 7. It meets the needs of supermarkets, department store, clothing store, sporting goods stores and others.
