The HEUS-T-037 is a universal USB to RS-232/485/422 converter. This bus-powered device requires no external power supply and is fully compatible with USB, RS-232, RS-422, and RS-485 standards. It seamlessly converts single-ended USB signals into RS-232, RS-485, or RS-422 signals.
Featuring zero-delay automatic transceiver switching, the device utilizes a unique I/O circuit to automatically manage data direction without the need for handshake signals (such as RTS or DTR). No jumper settings are required to switch between full-duplex (RS-232/422) and half-duplex (RS-485) modes, ensuring plug-and-play compatibility with all existing communication software and hardware interfaces.
