3810+ Transmitting 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 3810+ mainboard performance:
A. Original functions from YIJIA Electronics 3810+ mainboard:
1. Unique sensitivity automatic adjustment: the sensitivity will be changed in a high level when detecting the tag/label signal(4 selective levels through a Short Route)for 10/30 seconds, if there is no tag/label signal in detection area, the sensitivity will be changed in a based level again. It reduces the possibility of false alarms and improves the sensitivity of the system.
2. 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.
3. 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.
4. A fault fuse LED indicator: if the fuse is broken, the LED beside will light up immediately.
5. 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.
6. Anti-interference reinforcement selection: you can select the receiving board to resist more interfering signal by a Short Route JP4.
7. 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.
