QTAZMJPB UT-2577SM

CablesThe UT-2577/2578SM fiber optic modem supports RS-232/485/422 asynchronous communication. It is the best choice for connecting the remote terminal unit (RTU) to the HOST or SCADA controller. Supports RS-232/485/422 asynchronous protocols; can be combined and matched to use 2 RS-232, RS-485 or RS-422 ports and supports 2-wire RS-485 (half-duplex) and 4-wire RS-422 (full-duplex) mode. The RS-485 mode supports data transmission control (TXD or SD), this improves the adaptation to most software. Fibre optic MODEM supports numerous optical connections between asynchronous serial ports. Supports 2 asynchronous serial devices to communicate in full-duplex or half-duplex mode via optical fiber; communication distance can be up to 4km in multimode mode and 20km in single mode. The fastest transmission speed for RS-232 can be 115.2Kbps and for RS-485/422 can be 460Kbps. You can combine and match ports with different electronic standards; it is easy to connect RS-232 devices with RS-485/422 devices. It is a good replacement for RS-232 to RS485/422 converter, equipped with EMI/RFT functionality.UT-2577SM supports the transmission of two data signals: transmit and receive data. At the same time, it is equipped with RS-485/422 automatic data transmission control circuit; Zero delay conversion; All serial ports are connected via terminal block.Product name: Single-mode RS-232/485/422 Single Mode Fiber Optic MODEM Specific Model: UT-2577SMTransmission Distance: 20kmPoint-to-Point or ring circuit (point Multipoint).Supports asynchronous protocol RS-232, RS-422, RS-485RS-232, RS-422/485 work simultaneouslySupports RS485 2-bit (half-duplex) and 4-bit fullduplex operating modeSupport RS485 operating mode 460 kbps maxWith SC interface, FC, ST option
