The HEUS-T-034 is a universal, bus-powered USB to RS-485/422 converter that requires no external power supply. Compliant with USB, RS-422, and RS-485 standards, it converts single-ended USB signals into balanced differential RS-422 or RS-485 signals.

Featuring zero-latency automatic transceiver conversion and unique I/O circuitry, the HEUS-T-034 manages data flow direction without the need for handshaking signals (such as RTS or DTR). No jumper settings are required to switch between full-duplex (RS-422) and half-duplex (RS-485) modes.

The converter supports both point-to-point and point-to-multipoint communication, allowing for the connection of up to 32 devices. It supports Auto-Baud rates ranging from 300 to 921.6 kbps and ensures seamless integration across all modern communication software and hardware.
