Editorial Review
This itme is Like VSCOM USB-4COMi-M 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. Main Features Following communication modes are supported by UT-861 interface converter: 1) Point-to-point/4-wire full-duplex 2) Point-to-multipoint/4-wire full-duplex 3) Point-to-point/2-wire half-duplex 2) Point-to-multipoint/2-wire half-duplex When the converter is connected for full-duplex or half-duplex communication, a matching resistor (120 Ohm,1/4W) should be connected to the wire terminal for avoiding signal reflection and interference.
Features
1) 9-pin DB9 Interface w/ 8pin Terminal Block adapters
2) Supports Windows XP/Vista/7/X64, OSX, Linux
3) Plug-And-Play
4) Standard DB9 PIN interface.
5) USB to Quad RS-422/485 Optical Isolation/Metal case
