It supports multiple asynchronism\ncommunication protocols including RS-232,RS-485 and RS-422, and it also\nsupports a combination of two of the RS-232,RS-485 or RS-422 interfaces as\nwell as both of the working modes, i.e,Two-line (half-duplex) RS-485 and four-\nline(full duplex) RS-422.The ability to support RS-485 mode for data TXD or SD\nsending control greatly improves its compatibility with various kinds of\nsoftware besides a sharp simplification of control method. Various kinds of\nfiber connection between asynchronism serial interfaces are supported by\nUT-277 fiber modem. Both half duplex and full duplex communications through\nfiber between two asynchronism interface devices are supported with a\ncommunication distance as far as 4 kilometers for multi-mode and 20 kilometers\nfor single-mode. The transmission rate for RS-232 can reach a maximum of\n115.2KBPS,while for RS-485\/RS-422 a maximum of 460KBPS can be\nachieved.Interfaces of different electric standards can be mixed for use with\nnice EMI\/RFT performance,e.g,RS-232 devices can be connected to RS-485\/RS-422\ndevices,and the interface converter or photoelectric isolator can be replaced\nfrom RS-232 to RS-485.Two data signal transmissions are supported by UT-277:\ndata sending and data receiving. At the same time, automatic control circuit\nis alsoprovided for RS-485\/RS-422 data transmission. Zero delay for converting\ntime is achieved. ST interfaces are used for fiber connection.
