USB to RS-485 RS-422 Converter 4 Port RS485 RS422 Adapter DB9 Connector Isolated

Description: UOTEK USB to RS-485 RS-422 Converter USB2.0 4 Ports RS485 RS422 Adapter Serial DB9 Connector Optical isolation ESD UT-861A UT-861A is an USB to RS-485/422 converter with external power supply, built-in opto-isolator and DC/DC power isolation module. Compatible with USB, RS-422, RS-485 standards, it can convert single-ended USB signals to balanced differential RS-422 or RS-485 signals with built-in opto-isolator, capable of providing isolation voltages up to 2500Vrms, with fast transient voltage suppression protector, which is designed to protect RS-422/RS-485 interfaces, using Today's advanced TVS (TRANSIENT VOLTAGE SUPPERSSOR) transient voltage suppressor, under normal conditions TVS tube is a high resistance state, when the two ends of the TVS tube is subjected to an instantaneous high-energy shock, it can reduce the impedance of the two ends at a very high rate, absorbing a large current, thus clamping the voltage at its two ends at a predetermined value to protect the back circuit components from damage due to transient high-voltage shock. This protector effectively suppresses lightning (LIGHTNING) and ESD, providing 600W per line of lightning strike, surge protection, and surge voltage and transient overvoltage from various causes on the line, and the extremely small inter-pole capacitance ensures high speed transmission of the RS-422/RS-485 interface, with the RS-422 and RS-485 ends connected via DB9 male connectors. The converter is equipped with zero delay automatic transceiver, unique I/O circuit automatically controls the data flow direction without any handshaking signal (such as RTS, DTR, etc.) No jumper setting is required to achieve full duplex (RS-422) and half duplex (RS-485) mode conversion, plug and play. Ensure that all existing communication software and interface hardware are suitable. UT-861A opto-isolated interface converter can provide reliable connection for point-to-point and point-to-multipoint communication, each port of point-to-multipoint can allow connection of 128 RS-422 or RS-485 interface devices, data communication rate 300-128000bps, with power indicator and data flow indicator to indicate the fault situation, supported communication methods are USB to RS-422, USB to RS-485 conversion.
