Provide Full Or Half Duplex Signals Without A jumper! Connect your RS 422 or RS 485 peripheral to a USB Port and instantly protect against 600W lightning strikes and 15KV ESD surges. Using its FTDI FT232RL chip set, you’ll have plug-and-play features and transmission rates from 300 to 921,600bps automatically detected. Great for point to multi-point communication with up 32 devices connected per converter!
	Unique Circuit The converter contains a unique I/O circuit with an internal zero delay. The auto transceiver within controls the data stream automatically without any handshaking signals such as RTS, DTR, etc.
	Super Compact Design The GM-482422 is a small, compact converter that handles big communication jobs in converting RS 485 to RS 422.
	No Accidental Disconnects Make your connections safe, simple, and secure with screw down terminals on our RS422/485 adapter. Just strip your wires, insert, and tighten it down.

GM-482422 USB to RS485 / RS422 Converter FTDI Chip with Terminals photoelectric isolation interface converter can convert the single ended USB signal into difference RS422 or RS485 signal. There is also a rapid transient voltage suppression protector for protection of RS422 / RS485 interface with advanced TVS (Transient Voltage Suppressor) technology

Under normal conditions the TVS tube is in a state oh high resistance. However, when both ends of the TVS tube are hit by transient high energy, the impedance at the both ends can be depressed by the TVS at very high speed. After absorbing a high current, the voltage between the two ends is depressed and kept at a pre-set value; therefore no damage is caused to the electrical components behind the transient high voltage impact.
