USB To Serial RS232 Converter - Product

Other Specification :  USB To Serial RS232 Converter Standards:conforming To USBV1.0, 1.1 And 2.0 And EIA RS-232 USB Signals:VCC, DATA+, DATA-, GND And FG Supported Systems:Windows95/98/2000/XP/Vista Transmission Media:twisted-pair Cable Or Shielded Cable Operating Mode:asynchronous Working,point-to-point Or Point-to-multipoint 2 Wires (half Duplex) RS-232 Signals:TXD+,TXD-,RXD+,RXD-,GND Compatible With The Recommended Standards Of USB, RS-422 And RS-485, UT-885 Photoelectric Isolation Interface Converter Can Convert The Single-ended USB Signal Into Balance Differenced RS-422 Or RS-485 Signal. The Built-in Photoelectric Isolator Can Provide An Isolation Voltage Of As High As 2500Vrms. Also, There Is A Rapid Transient Voltage Suppression Protector For Protection Of RS-422/RS-485 Interface With Advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) Technology Adopted. 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 End Scan 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 Interface Is Ensured By The Tiny Capacitance Between The Poles. RS-422 And RS-485 Interfaces A DB9 Male Connector Is To Be Used For Connection. The Unique I/O Circuit Of The Internal Zero Delay Auto Transceiver Contained In The Converter Controls The Data Stream Direction Automa
