HEUS-T-033 is a universal USB to RS-485/422 converter. The baud rate is 300 to 128,000 bps. This product can be connected with 128 RS-422 or RS-485 devices. It complies with USB and RS-485/422 standards and converts single side USB signal to a balanced differential RS-485 or RS-422 signal. The built-in photoelectric isolator can provide as high as 2,500 Vrms isolated voltage. This series adopts advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) instant voltage restraint to protect RS-485/422 interface. This voltage restraint provides 1,500W surge and lightning protection for each wire of the ports. The tiny inter-electrode capacitance ensures high speed transmission for RS-485/422 ports. This converter has built-in zero delay auto receiving and transmitting conversion. Its unique I/O circuit automatically controls data flow direction without any handshake signal (RTS, DTR). There is no need for jumper wire setting to implement the conversion between full-duplex (RS-422) and half-duplex (RS-485) mode. This product is compatible with current communication software and hardware.
