Description:   


    Being a multi-function fiber modem in support of asynchronism RS-232,RS-485 and RS-422 communication interface, UT-277 is the best choice for the connection from remote terminal unit (RTU) to host(HOST) or Supervisory Control and Data Acquisition (SCADA) . It supports multiple asynchronism communication protocols including RS-232,RS-485 and RS-422, and it also supports a combination of two of the RS-232,RS-485 or RS-422 interfaces as well as both of the working modes, i.e. Two-line(half-duplex) RS-485 and four-line(full duplex) RS-422.The ability to support RS-485 mode for data TXD or SD sending control greatly improves its compatibility with various kinds of software besides a sharp simplification of control method. Various kinds of fiber connection between asynchronism serial interfaces are supported by UT-277 fiber modem. Both half duplex and full duplex communications through fiber between two asynchronism
