  - TD-108 is an active lightning-proof optical barrier RS-232 to RS-485/422 converter (also known as RS-485/422 photoelectric isolator, optical barrier serial port converter, RS485 converter), is Shenzhen Tiandi Huajie Communication Co., Ltd. in order to better solve and protect the data communication between RS-232 serial port equipment and RS-485/422 serial port equipment and professional design. . The RS485 converter can transparently convert single-ended RS-232 signals into balanced differential RS-485 or RS-422 signals, and has the function of automatic identification of RS-485/RS-422 signals without manual adjustment. RS485 converter uses two isolation methods at the same time: one is lightning protection and optical coupling isolation, the second is circuit isolation, Double Transistors below, played a very strong lightning protection and photoelectric isolation function. RS485 converter connection enables point-to-point, point to multipoint connections. When you point to multipoint connections, you can connect 128 RS-485/RS-422 devices. RS485 converter is the best choice for outdoor expansion system.
