Product Description:

UT-206 optical isolation interface converter compatible with RS-232C, RS-422, RS-485 standard, able to single-ended RS-232 signals are converted to balanced differential RS-422 or RS-485 signal, the built-in photoelectric isolation, can provide up to 2500Vrms isolation voltage, fast transient voltage suppression protector, this protection is designed to protect the RS-422/RS-485 interface, using today's advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) Transient Voltage suppressors, under normal circumstances, TVS tube in a high-impedance state, When the the TVS tube ends subjected instant high energy impact, it can be a very high speed to the impedance across the decreased absorption of a large current, so that both ends thereof The voltage is clamped at a predetermined value, and to protect the back of the circuit element is not damaged due to transient high pressure shock. This protection can effectively suppress the Lightning (LIGHTNING) provides line 600W lightning surge protection power, as well as a variety of reasons on the line generated surge voltage and transient over-voltage, and a very small inter-electrode capacitance to ensure that the RS speed transmission interface -422/RS-485 of RS-232 interface port via a DB9 female connector is compatible with standard RS-232C interface connected to the RS-422, RS-485 side through DB9 male connector connected. Converter with internal zero delay automatic transceiver conversion, unique I / O circuit automatically controls the data flow direction, without any handshaking signals (such as RTS, DTR, etc.), without the jumper settings to achieve full-duplex (RS- 422), half-duplex (RS-485) mode conversion, plug-and-play. ensure that it meets all the existing communication software and interface hardware, and does not require modification of the RS-232-based work of any software. 
UT-206 optical isolation interface converter for point-to-point and point-to-multipoint communications provide a reliable connection, point-to-multipoint each converter can be allowed to connect 32 RS-422 or RS-485 interface devices, data communication speed 300-115.2KBPS, with a power indicator and data flow indicator to indicate fault conditions, communication support RS-232 to RS-422, RS-232 to RS-485 conversion.
