Physical Specification

Other Specification :  UT-890 , 1-port USB Serial Cable Converter , Surge Protection Standards:Conforming To USBV1.1 And 1.0, EIA RS-485 And RS-422, Backwards Compatible USB Signals:VCC, DATA+, DATA-, GND And FG Supported Systems:Windows95/98/2000/XP/Vista/Win7/Linux And IMAG Are Supported Transmission Media:twisted-pair Cable Or Shielded Cable Operating Mode:Asynchronous, Point-to-point Or Point-to-multipoint, 2-line Half Duplex And 4-line Full Duplex With Rapid Development Of Computer Industry, USD Is Taking The Place Of Various Kinds Of Traditional Low Speed Peripheral Interfaces. However, RS-485/RS-422 Interface Designs Are Still Used In Many Of The Important Facilities Under Current Industrial Environment. Therefore, Converter Is Used By Many Users To Implement The Data Transmission From USB Of A Computer To RS-485/RS-422 Equipments. 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 Suppressors (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 Pos
