Utek Ut-277sm-sc RS-232 / 422 / 485 To Optical Fibre Media Converters Being a multi-function fibre modem in support of asynchronism RS-232,RS-485 and RS-422 communication interface,UT-277 is the best choice for the connexion from remote terminal unit (RTU) to host(HOST) or Supervisory Control and Data Acquisition(SCADA). 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 fibre connexion between asynchronism serial interfaces are supported by UT-277 fibre modem. Both half duplex and full duplex communications through fibre between two asynchronism interface devices are supported with a communication distance as far as 4 kilometres for multi-mode and 20 kilometres 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 422. Theerfaces 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-422. The data signal transmissions are supported by UT-277: data sending and data receiving. At the same time, automatic control circuit is alsoprovided for RS-485/RS-422 data transmission. Zero delay for converting time is achieved * Transmission media: double multi-mode * Working mode: asynchronous half/full duplex, server/client mode * Power pre-consumption: 12db * Working environment: -25; to 70;, relative humidity 5% to 95%
