Being a multi-function fiber modem in support of asynchronism RS-232,RS-485 and RS-422 communication interface, UT-2578 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-2578 fiber modem. Both half duplex and full duplex communications through fiber between two asynchronism interface devices are supported with a communication distance as far as 4 kilometers for multi-mode and 20 kilometers for single-mode. The transmission rate for RS-232 can reach a maximum of 115.2Kbps, while for RS-485/RS-422 a maximum of 460KBPS can be achieved. Interfaces of different electric standards can be mixed for use with nice EMI/RFT performance, e.g. RS-232 devices can be connected to RS-485/RS-422 devices, and the interface converter or photoelectric isolator can be replaced from RS-232 to RS-485. Two data signal transmissions are supported by UT-2578: data sending and data receiving. At the same time, automatic control circuit is also provided for RS-485/RS-422 data transmission. Zero delay for converting time is achieved. ST interfaces are used for fiber connection.
