GM-482422 USB to RS-422 / RS-485 Converter FTDI Chip with Terminals photoelectric isolation interface converter can convert the single ended USB signal into difference RS422 or RS485 signal. The built-in photoelectric isolator of the USB to RS-422 / RS-485 Converter can provide an isolation voltage as high as 2500Vrms. There is also a rapid transient voltage suppression protector for protection of RS422 / RS485 interface with advanced TVS (Transient Voltage Suppressor) technology.
The protector can effectively restrain lighting or ESD (Electro-Static Discharge) with a protection voltage of 600w on each line for lightning surge and transient voltage events, while transmission of RS-422 / RS-485 is maintained by capacitors between the poles. The unique I/O circuit of the internal zero delay auto transceiver contained in the converter controls the data stream direction automatically without any handshaking signals (Such as RTS, DTR, etc).
The GM-482422 USB to RS-422 / RS-485 Converter is plug-and-play without any jumper settings needed for mode shifting between full duplex (RS-422) and half duplex (RS-485). USB to RS-422 – RS-485 Converter is applicable for all existing communication software and interface hardware. The converter uses an FTDI Chip for its operations and has a terminal based connection.
