YH-252 Photoelectric Isolation Interface conversion is compatible with RS-232C, RS-422, RS-485, can be single-ended RS-232 signals converted to balanced differential RS-422 or RS-485 signal, the built-in photoelectric isolation is able to provide 3500V isolation voltage, two fast transient voltage suppressor (TVS) can effectively suppress the Lightning (Lightning) and ESD, lightning surge protection power of 1000W per line, you can effectively prevent lightning strike and common interfere. RS-232 interface via a DB9 female connector with PC, IPC, or laptop connected to the RS-422, RS-485 end connected through a convenient 6-bit plug terminals or DB9 connector. RS-485 supports two-wire half-duplex, that is RS-485 only two lines that you want to send and receive data, handshaking signals (such as RTS, Request To Send) is usually to control the direction of data transmission, ATC-108N Photoelectric Isolation Interface Converter internal circuitry to automatically sense the direction of data flow, and automatically switch to control it, you can easily form an RS-485 network without any handshaking signals, this RS-485 enable control is completely transparent, and do not need to make any changes to the software RS-232 based on the previous work. ATC-108N optical isolated interface converter can be point-to-point, point-to-multipoint communication delivers a reliable connection point allows connecting 128 RS-422 or RS-485 interface devices, data communication speed from 0 -115.2KBPS, three power and data flow indicator to indicate fault conditions to support communication RS-232C to RS-422, RS-232 to RS-485 converter.
