Product Description:

UT-217 optically isolated interface converter compatible with RS-232C, RS-485 RS-485 standard, RS-232 single-ended signal conversion as balanced differential signal, a built-in optical isolation, can provide up to isolation voltage of 2500Vrms, with fast transient voltage suppression protector, this protection is designed to protect the RS-485 interface, using today's state-of-the-art the TVS (TRANSIENT VOLTAGE SUPPERSSOR), transient voltage suppressor TVS tube, under normal circumstances a high-impedance state, when the the TVS tube ends subjected instant high energy impact, it can be an extremely high speed to the impedance across the lower absorption of a large current, so that the voltage across it is clamped at a predetermined value protect the back of the circuit element is not damaged due to transient high pressure shock. This protection can effectively inhibit lightning (LIGHTNING) and ESD, lightning surge protection power line 600W, and for various reasons on the line generated surge voltage and transient overvoltage and electrode capacitance to ensure minimal the RS-485 interface, high-speed transmission. RS-232 interface port via a DB9 female connector compatible with standard RS-232C interface is connected to the RS-485 side through the RJ45 and four terminal for the output. 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.), no jumper setting 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 any software to modify the previous RS-232-based work. 
UT-217 passive optical isolation interface converter for point-to-point and point-to-multipoint communications provide a reliable connection, point-to-multipoint each converter allows connecting 32 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-485 converter.
