First, use 
 Boston Electronics OPT232EX [S], OPT485EX [S] Series RS232/485 / fiber optic repeater converters for: 
 1, and RS232/485 optical fiber communications relay, which is the extension of optical fiber communications from the serial 
 2 serial optical multi-machine communication, that is, RS232 or RS485 interface to multiple access fiber optic communication network with a serial 
 3, RS232 or RS485 while achieving all the way to the two fiber optic conversion. Boston OPT232EX [S], OPT485EX [S] series is the world's smallest RS232/485 / fiber optic repeater converter. 

 Model OPTCANEX (multi-mode) and OPTCANEXS (single mode) of the CAN / fiber optic repeater converter used to implement the extension of optical fiber transmission CAN, CAN multi-fiber network when the CAN node conversion can also be used while a CAN signal into two groups of optical fiber transmission. 

 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 
 Boston OPT232EX [S], OPT485EX [S], OPTCANEX [S] Series fiber optic repeater converter adapter box shape for the DB25/DB25 size. Use one to many mode ST fiber connectors and a pair of single-mode ST fiber optic connectors, the middle of a cable connected to a port DB9 RS232 or CAN interface, needle seat converter and 5V power supply pin. OPT232EX [S] of the RS232 port can be connected with Boston electronic RS232/RS485/422 converters constitute OPT485EX [S]. OPT232EX [S], OPTCANEX [S] requires an external 5V DC power (<50mA). 

 Fiber optic repeater converter 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 
 Boston Electronics OPT232EX [S] the highest rate of fiber optic repeater converter 115.2Kbps. All without any initialization settings! Boston zero delay automatic send and receive unique conversion technology, to ensure that suitable for all software! 

 Boss of all e-CAN / fiber optic repeater converter without any initial setup! Ensure that it meets all the software! The maximum communication speed fiber-optic multi-machine communication 100KbpsCAN map and Boston's RS232/485 / optical multi-machine communication diagram is the same.
