First, use 

 Boston Electronics OPT232U (multi-mode), OPT232US (single mode) general-purpose serial / fiber converter RS-232/485/422 level used to achieve a common optical fiber transmission, but also the world's smallest optical converter. OPT232U [S] can be used for the user's RS-232/485/422 serial port and the optical interface of different manufacturers are connected. OPT232U [S] of course, can also be used in pairs, but also with a variety of Boss Media Converters communication. 

 Second, the hardware installation 

 OPT232U general-purpose serial / optical converter (multi-mode) shape for the DB-9/DB-9 adapter box size, which DB-9 (socket) end of the RS-232 level, requires an external 5V power supply, using a of ST fiber connectors. OPT232US general-purpose serial / optical converter (single mode) shape for the DB-25/DB-25 adapter box size, which DB-25 (socket) end of the RS-232 level, requires an external 5V power supply, using a of ST fiber connectors. 

 OPT232U the DB-9 hole side can be directly extrapolated PC-DB-9 pin RS-232 port (needle seat), only use RXD-2, TXD-3, GND-5 three signal lines. OPT232US the DB-25 terminal can be directly extrapolated holes PC-DB-25 pin RS-232 port (needle seat), only use RXD-3, TXD-2, GND-7 three signal lines. OPT232U [S] of the DB-9 or DB-25 side can be connected with a variety of Boston RS-485/422 RS-232/485/422 converter used to implement a common fiber optic conversion. 

 OPT232U [S] requires an external 5V power supply (4.5 V to 5.5V, consuming less than 100mA). OPT series fiber converters use ST when the first transmitter via an optical access each other's receivers ST head. Boston OPT series Fiber Converter supports multi-machine communication. 

 Third, the performance characteristics 

 Boston Electronics OPT232U [S] generic serial / fiber optic converter speed 0-115.2Kbps. All without any software initialization settings! Logic has an optional sign any combination of input and output, ensure that it meets all the software and serial optical interface!
