UT-2216 interface converter compatible with RS-232C, RS-485 standard, single-ended RS-232 signals are converted to balanced differential RS-485 signals, built-in fast transient voltage suppression protector This protectordesigned to protect the 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 TVS tube ends is subjected to instantaneous high energy impact, high speed can be the impedance across the decreased absorption of a large current, thereby the voltage across it 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 -485 interface 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 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.), no jumper setting half-duplex (RS-485) mode converter, plug-and-play. Ensure that it meets all the existing communication software and interface hardware, do not need to modify any software RS-232-based work.
UT-2216 interface converter can provide reliable connections for point-to-point, point-to-multipoint communication, to-multipoint each converter allows to connect up to 32 RS-485 interface devices, data communications rate of 300-115.2KBPS LEDs indicate fault conditions to support communication RS-232 to RS-485 converter with power indicator and data traffic.
