Video character superposition module-OM708 Video character superposition module is used to make the character data stack on the video screen, so as to realize checking the real-time dynamic data in supervisory room. The module is called NE-OM708, also called OM708 module. It is often used in users' system, help to realize data information superimposed on video screen function. The OM708 module supports NTSC and PAL video system, PAL is the default.It needs to tell us which way is your choice. In addition,there is another choice should be told, it is the communication way,please choose one(from RS232,RS485 and TTL; the default is RS232 communication interface) for your order. The size of the OM708 is 57mm(L)*25mm(W),volume is small and exquisite, it is easily to applicate in user's system.By the way, as you see, it could realize to display any character content at any position on the video screen. Its parameter list as follows: OM708 module enables our users to edit and modify the character library at will with the software we provide. Users can choose where to display at any time with reduced instruction set. OM708 module has three displaying effects: setting up the overlapping backgrounds, the blinking characters and reverse video text. It can achieve the function of amplifying intergrated vedio images and driving the output of two-way vedio images. The charcater library could be upgraded with our software. It has built-in RTC(Real Time Clock). RS232/RS485/TTl/SPI/IIC communications interfaces are available but the default one is RS232. Any special needs about Video character superposition module-OM708, please feel free to tell us. We can provide customized service for you. You are welcome to ask for OM708 module's English version manual , and do not worry if you have any question about it.
