USB interface is gradually replacing the old-fashioned low-speed peripheral interfaces of PC with the continuous development of PC industry. But many vital devices in current industrial environment is still designed using RS-485/RS-422 interface, so the USB to RS-485/RS-422 converters are needed to transfer data between PC and RS-485/RS-422 devices.

UT-861 is a universal USB/RS-485/422 converter which doesn’t need external power supply and has built-in opto-isolator and DC/DC power isolation module. It is compatible with USB ,RS-422 and RS-485 standards, and it can convert single-end USB signal to balanced differential RS-422 or 485 signal. The built-in photoelectric isolator can provide isolating voltage up to 2500Vrms and it equips with high-speed transient voltage supressor which is designed to protect the RS-422/RS-485 interface. The advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) presents high-impedance state under normal conditions, and it can rapidly decrease the resistance between its two ends while it’s withstanding transient high-power impulse so as to absorb the high current and clamp the voltage across it to a preset value, and then the following components will not be damaged by the transient high-voltage impulse. This suppressor can effectively restrain lightning and ESD (electro-static discharge) with lightning surge protection power of 600W for each line, and it also can restrain surge voltage and transient over-voltage on the lines for any reason. Extremely small interelectrode capacitance ensures high speed data transmission of RS-422/RS-485 interface.The RS-422/RS-485 end is connected through male DB9 connector.It has built-in automatic transmit-receive switch without time delay. The unique I/O circuit can be used to automatically control the direction of data flow without any hand-shaking signals(such as RTS and DTR) and full-duplex(RS-422) and half-duplex (RS-485) can be implemented without jumper configuration,so as to make it plug-and-play and applicable to all existing communication software and interface hardware.

 UT-861 industrial photoelectric isolated interface converter can provide reliable connection for point-to-point or point-to-multipoint communication. Maximum 128 RS-422 or RS-485 interface devices can be supported for the point-to-multipoint communication. Data communication rate can be 300-128000BPS, and the power indicator light and data traffic indicator light can be used for malfunction indication. USB to RS-422 and USB to RS-485 conversions are supported.
