 UT-890 is a universal USB/RS-485/422 converter. without external power supply needed. Compatible with USB,RS-422 and RS-485 standards, UT-890 is capable to perform the conversion from single-ended USB signal into balance differenced signal of RS-422 or RS-485. Quick state-of-the-art transient voltage suppressor (TVS) and discharge tube are adopted to protect the RS-422/RS-485 interfaces. Under normal conditions,the TVS tube is in the state of high resistance. However,when both ends of the TVS tube are hit by a transient high energy,the impedance at both ends can be depressed by the TVS at a very high speed, and after absorbing a high current, the voltage between the two ends is suppressed and kept at a pre-set value, therefore no damage is caused to the electrical components behind by the transient high voltage impact.  The protector can effectively restrain lightning or ESD (electro static discharge) with a protection voltage of 600W on each line for lightning surge and surge voltage or transient over voltage possibly caused up by various reasons, and  at the same time, a high-speed transmission of RS-422/ RS-485 interfaces is ensured by the tiny capacitance between the poles. RJ-45 and DB9 male connectors are used for connection from RS-422 and RS-485 to other equipments. The unique I/O circuit of the internal zero delay auto transceiver contained in the converter controls the data stream direction automatically without any handshaking signal (for example RTS,DTR etc). The converter is plug-and-play without any jumper settings needed for mode shift between full duplex (RS-422) and half duplex (RS-485). All these features ensure a universal application on all the existing communication software and hardware interfaces.
