It complies with USB and RS-485\/422 standards; it converts single\nside USB signal to a balanced differential RS-422 or RS-485 signal. The built-\nin optoelectronic isolator can provide as high as 2,500Vrm isolated voltage;\nthe fast instant voltage restraint is designed to protect RS-422\/RS-485\ninterface; it adopts advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) instant\nvoltage restraint; normally, TVS tube is in high impedance state; when both\nsides of TVS tube suffer from high power impact in a sudden, the voltage\nrestraint will fast lower the impedance from both sides, and absorb in big\ncurrent; with this, the voltage on both sides are fixed at presupposed value,\nprotects the component of circuit from damage. This voltage restraint provides\n1500W each wire with lightning and ESD protection, and surge voltage and\ninstant overvoltage protection on circuit which causing by all reasons; the\ntiny interelectrode capacitance ensures high speed transmission for RS-422\/485\nports. RS-485\/422 port adopts RJ45 or DB9 male as connector. This converter is\nwith built-in zero delay auto receiving and transmitting conversion and unique\nI\/O circuit auto control data flow direction without any handshake signal\n(RTS, DTR); there is no need jumper wire setting for full duplex (RS-422) and\nhalf duplex (RS-485) mode, plug \u0026amp; play. It is compatible with current\ncommunication software and hardware. UT-820E optoelectronic converter supports\npoint to point, point to multipoint communication; for point to multipoint, it\ncan be connected with 128 RS-422 or RS-485 devices, the baudrate is\n300-460800bps; the power and data flow indicators show the status of the\ncommunication.
