Under what circumstances does the RF anti-theft system need to be set up for synchronous connection?
射频防盗系统 设备在工作中会受到同频信号的干扰，射频防盗系统的工作原理是利用无线电，接收天线在无联机的状态下会接收到另外一发射天线发射过来的信号； In general, if you use 2 transmissions or more, you need to synchronize the connection, because the radio frequency anti-theft system equipment will be interfered by the same frequency signal during work. The working principle of the radio frequency anti-theft system is to use the radio, and the receiving antenna is offline. Will receive signals transmitted by another transmitting antenna;
射频防盗系统 两套设备及以上应该怎么联机呢，首先，由其中一支发射作为主发射，另外一支则为副发射，用屏蔽线（设备会配置）从主发射主板中的Sync out端口链接到另外一支发射Sync In 端口，再将副发射中的Master 设置成Slave；（主发射保持默认Master）即可； So how should two sets of RF anti-theft system and above be connected? First, one of them should be used as the main transmitter and the other as the secondary transmitter. Use shielded cable (device will be configured) from the Sync out port on the main board. Link to the Sync In port of another transmitter, and then set the Master in the secondary transmitter to Slave; (the main transmitter remains the default Master).
Multiple sets of equipment are connected with one of the launches as the master launch. If we choose the left-most launch as the master launch, in the same way, the master launch remains the default Master and all other launches are set to Slave; Sync out in the left launch motherboard is linked to the Sync In port of the second launch, and then a shielded cable is used to link from the Sync out port of the second launch to the Sync In port of the third launch ... A maximum of 10 transmitters can be synchronized. A synchronization signal linker is required for more than 10 transmitters.
联机工作时要检查联机线的好坏、检查联机线接线是否松动或接错，检查发射板的主，副发射设置开关是否设置正确、 调换主，副发射、调换联机线向位， 所以平时在使用的过程中一定要小心，在安装的时候要一次性安装好，尽量不要出现什么遗留问题。 When the RF anti-theft system works online, check the quality of the connection line, check whether the connection of the connection line is loose or wrong, check whether the main and sub-transmission setting switches of the transmitting board are set correctly, change the main, sub-transmission, and change the line direction Therefore, you must be careful in the process of use, and install it at one time during installation, so as to avoid any remaining problems.
