First, use 
 Boshi electronic OPT232AL [S] Series RS-232 fiber optic converter for full signal: RS-232 to achieve full signal of the optical fiber transmission, including the main signal RXD, TXD, GND and the handshake signals RTS / DTR and CTS / DSR. OPT232AL [S] is the world's smallest full signal RS-232 fiber optic converter. Using optical fiber communication with high isolation voltage, electromagnetic interference, anti-lightning and so on. Patented product, Beware of imitations! Patent number: 8256. 

 Second, the hardware installation 
 Boshi OPT232AL [S] Series RS-232 fiber optic converter full signal shape for the DB-25/DB-25 adapter box size, the use of two pairs of multi-mode ST fiber connectors, or two pairs of single-mode ST fiber optic connectors, the middle of a RS-232 DB-9 port and 5V power supply pin socket. DB-9 socket for RS-232 port can directly or through DB-9 extension cable outside the PC, plug the RS-232 port (needle seat). 
 OPT232AL [S] must be used in pairs. OPT232AL [S] full signal converter fiber optical receiver (RX1, RX2) and fiber optic transmitter (TX1, TX2) see product label. Then use the other side TX1 RX1, TX2 access each other's RX2; RX1 access each other's TX1, RX2 access each other's TX2. Are optional SC, FC-type fiber connectors. 

 Third, the performance characteristics 
 OPT232AL [S] the highest rate of 115.2Kbps. Without any initial setup! OPT232AL [S] through optical TX1, RX1 transmission main signal RXD, TXD, GND, fiber TX2, RX2 transfer handshake signal RTS or DTR, CTS, or DSR.
