First, use 

 Boshi electronic OPT2322 [S] Series RS-232 / Dual fiber optic converter for: implements all the way RS-232 (or RS-485) simultaneously to the two fiber optic conversion. Is the world's smallest RS-232 (485) / dual fiber converter. As a result of optical fiber as a communication transmission medium, high isolation voltage, electromagnetic interference, anti-lightning and so on. 

 Second, the hardware installation 

 Boshi OPT2322 [S] Series RS-232 / Dual Fiber converter adapter box shape for the DB-25/DB-25 size, use-many-mode ST fiber optic connectors or a pair of single-mode ST fiber optic connectors, the middle of a cable connected to a RS-232 DB-9 pin port and 5V power supply pin seat. Block DB-9 pin RS-232 ports can be connected with Boshi electronic RS-232/RS-485 converter for RS-485 connection Composition of Population RS-485 / Dual fiber optic converter. OPT2322 [S] requires an external 5V DC power (<50mA). 

 OPT2322 [S] Serial / Fiber Converter dual optical receiver (RX) and optical transmitter (TX) in the product label. ST head transmitter used by the other side of the receiver optical fiber access ST head. Attention to maintaining the seat ST fiber converter, fiber optic ST-head cleaning, if not connected, be sure to ST and ST blocks first child with matching rubber plug cover. Are optional SC, FC-type fiber connectors. 

 Third, the performance characteristics 

 Boshi electronic OPT2322 [S] serial / dual fiber converter highest rate 115.2Kbps. All without any initialization settings! Boshi zero delay automatic send and receive unique conversion technology, to ensure that suitable for all software!
