UTEK UT-277SM-SC RS-232/422/485 to Optical Fiber Media Converters


Super Savings Item! Save 34% on the UTEK UT-277SM-SC RS-232/422/485 to Optical Fiber Media Converters by U-Tek at Prensa Digital PR. MPN: LYSB00L0RRRJ4-CMPTRACCS. Hurry! Limited time offer. Offer valid only while supplies last. 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)


Product Description & Reviews

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 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-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% Note: need 2pcs UT-277 to create communication.One for Tx; another for Rx.
