LREG1004PT-POE is a quad-port gigabit PoE+ Ethernet image acquisition card independently developed by Shenzhen Lianrui Electronics Co., Ltd. based on the Intel main control chip solution.The Ethernet frame grabber has a TOE (Trigger Over Ethernet) function, which integrates an advanced Ethernet trigger based on FPGA, which can accurately synchronize multiple cameras to trigger acquisition, which reduces the cost of hardware and IO in practical applications.There is also a software trigger on the TOE trigger mode. This trigger mode is more flexible and convenient. You can directly input a specific trigger online without adding additional hardware devices. Then the entire TOE trigger mode is as follows: 1. External synchronous pulse input, 2. Quadrature encoder input. These two are based on FPGA hard-wired logic, which can ensure accurate and reliable triggering.
