With the continuous development of the PC industry, USB interfaces are gradually replacing various low-speed peripheral interfaces of old PCs. Many important devices in the former industrial environment still use RS-232/RS-485/RS-422 interface design, so many users use a USB to RS-232/RS-485/RS-422 converter to implement communication between a PC and RS-232/RS-485/RS-422 devices.
HEUS-T-037 is a universal USB to RS-232/RS-485/422 converter that does not require an external power supply and is compatible with USB, RS-232, RS-422, RS-485 standards. This product can convert single-ended USB signals to RS-232, RS-485 or RS-422 signals.

The converter has zero-delay automatic transmission and reception conversion, and the unique I/O circuit automatically controls the direction of data flow without any handshake signal (such as RTS, DTR, etc.). It does not require jumper settings to achieve full-duplex (RS-232/RS-422) and half-duplex (RS-485) mode conversion, which ensure compatibility with all existing communication software and interface hardware.

HEUS-T-037 interface converter can provide reliable connection for point-to-point and point-to-multipoint communication.The converter allows the connection of 128 sets RS-485 or RS-422 interface devices, with a data communication rate of 300 bps-921.6 Kbps. The supported communication methods include USB to RS-232, USB to RS-485, USB to RS-422 conversion.
