Industrial serial expansion
The UOTEK UT-794I adds four RS-422 and RS-485 ports through a single PCI Express x1 slot. It targets industrial automation, building management and legacy equipment integration where long-distance serial links are required.
Build integration
The card occupies one x1 PCIe lane at 2.5 Gbps and connects via a DR44 connector to a breakout cable. Optical isolation and 600 W surge protection per line shield the host system from ground loops and transient voltages on the serial bus.
Sustained operation
Rated for continuous use from -40 °C to 85 °C, the adapter maintains signal integrity over 1.2 km at up to 921.6 Kbps. Hardware flow control and configurable parity, data and stop bits keep framing errors low during extended high-throughput sessions.
