RS-232/482/422 Converter (OPT-277 series)

OPT-277 Series is one kind can offer RS-232/485/422 serial port carry transparent optic fiber modem of transmission to get end to user, no need patch cords set up, switch over automatically, and can detect and examine the signal speed automatically, zero delays time to transmit automatically. OPT-277 Series adopt optic fiber transmit, have isolate protection, data privacy is fine, working steady, data, such threats to communication equipment as the wave is welled up and interfered with electromagnetically that the effective one has prevented the abominable environment from being struck by lightning, can work in the abominable and dangerous environment reliably. 
    ●Extend RS-232/485/422 transmission up to 120Km with single-mode
    ●Transmit asynchronously, point to point, speed reach 500Kbps
    ●Examine signal speed automatically, zero delay time
    ●Plug-and-Play(hot-pluggable, data format auto-sensing & self-adjusting)
    ●Support RS-232/485/422 interface type, but only one RS-232/ RS-485/ RS-422 port can be connected at a given time
    ●9~36VDC power supply input(2 bit terminal block)
