Passive USB to RS485 RS422 Serial Converter Adapter USB to RS422 Converter UT-885 Point to Multipoint Communication

Compatible with USB, RS-422, RS-485 standards Ability to convert single-ended USB signals to balanced differential RS-422 or RS-485 signals Using TVS (TRANSIENT VOLTAGE SUPPERSsoR) transient voltage suppression protector This protector is designed to protect the RS-422/RS-485 interface. Under normal circumstances, the TVS tube is in a high resistance state. When both ends of the TVS tube are subjected to an instantaneous high-energy shock, it can break the two ends of the TVS tube at a high speed. The impedance of the terminal is reduced, and a large current is absorbed, thereby clamping the voltage at both ends to a predetermined value, and protecting the following circuit components from damage due to transient high-voltage shocks. This protector can effectively suppress lightning (LIGHTNING) and ESD, providing 60OW of lightning strike and surge protection power per line, as well as surge voltage and transient overvoltage generated on the line due to various reasons, and small inter-electrode capacitance It ensures the high-speed transmission of the RS-422/RS-485 interface, and the RS-422 and RS-485 ends are connected through the terminal block. The converter has zero-delay automatic transceiver conversion inside The I/O circuit automatically controls the direction of the data flow, without the need for handshake signals (such as RTS, DTR, etc.) without jumper settings to achieve full-duplex (RS-22), half-duplex (RS-485) mode conversion, plug and play . Make sure to fit existing communication software and interface hardware.
