First, use 

 Boshi electronic ultra-small passive RS-232 / Fiber Converter with Boston OPT232 [S] Series RS-232 / Fiber Converter full functionality, smaller, and adds support for three-wire RS-232 function. 

 Used to implement the RS-232 optical transmission, in particular, only received (RXD), fat (TXD), ground (GND) three lines of the RS-232 port passive optical transmission, such as RS-232 instrumentation port. 

 Boshi invented and pioneered electronic without an external power supply RS-232 / Fiber Converter is the world's smallest optical converter. As a result of optical fiber as a communication transmission medium, high isolation voltage, electromagnetic interference, anti-lightning and so on. 

 Boshi fiber converters are widely used in various industrial process control, distributed data collection and other occasions, especially for power system automation, traffic control and other departments. 


 Second, the hardware installation 

 OPT232-9-type RS-232 / Fiber Converter (multi-mode) shape for the DB-9/DB-9 adapter box size, which DB-9 (socket) at one end directly into the DB-9 pin RS-232 pin seat, no external power supply, use a pair of ST fiber optic connectors. 

 OPT232S-9-type RS-232 / Fiber Converter (single mode) shape for the DB-9/DB-25 adapter box size, which DB-9 (socket) at one end directly into the DB-9 pin RS-232 pin seat, no external power supply, use a pair of ST fiber optic connectors. 

 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. 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. 

 Third, the performance characteristics 

 Boshi electronic OPT series RS-232 / Fiber Converter more than the maximum rate of 115.2Kbps. All without any initialization settings! Boshi zero delay automatic send and receive unique conversion technology, ensure that it meets all of the software! Ensure access three-wire RS-232 are not required to supply 口!
