描述： Take advantage of the inherent EMI/RFI resistance, as well as the security, offered by fiber. Also, eliminate ground loops! Gives you the flexibility to link RS-232, RS-422, or RS-485 async serial devices over multimode fiber optic cabling. 规格： Use this compact device to extend your RS-232, RS-422, or RS-485 communications over a secure fiber optic link! Use point-to-point or in a multidrop fiber ring configuration in which multiple serial devices communicate with another. Supports full- or half-duplex communications over two fibers at distances up to 4 kilometers (2.5 mi.). To extend a link farther, add the Fiber Optic Repeater (ME611A-US). Also converts RS-232 to RS-422/RS-485. Can be used with most multimode fiber. The LED emitter and photodetector operate in the 820-nm fiber wavelength. Set mode of operation for RS-422 or RS-485 with DIP switches.
