Description:
Being a multi-function fiber modem in support of asynchronism RS-232, RS-485 and RS-422 communication interface, UT-2377 is the best choice for the connection from remote terminal unit (RTU) to host of Supervisory Control and Data Acquisition (SCADA). It supports multiple asynchronism communication protocols including RS-232, RS-485 and RS422, 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-2377 fiber modem. Both half duplex and full duplex communications through fiber between two asynchronism interface devices are
