Industrial serial expansion
The UOTEK UT-794 adds four RS-422/485 ports to a PC through a single PCI-Express x1 slot. It is built for industrial automation, data-acquisition and legacy-equipment integration where balanced differential signalling is required.
DB44 breakout connector
The card presents one DR44 connector that carries all four ports; a separate breakout cable splits the signals into individual DB9 ports. This single-connector design determines whether the card fits your existing cabling and panel layout.
Sustained industrial operation
The board operates continuously from -40 °C to 85 °C and provides 600 W surge protection plus ±15 kV ESD protection on every line. Optoelectronic isolation and TVS clamping keep the ports stable during long cable runs up to 1.2 km at 921.6 Kbps.

שאלות על הפריט הזה
What does the X1 2.5Gbps PCI Express bus mean for real-world throughput?
The card uses a single-lane PCIe link rated at 2.5Gbps, so all four serial ports share that bandwidth; aggregate throughput cannot exceed the lane limit.
Which signalling standards does the DR44 connector support and what distance limit applies?
The DR44 connector carries both RS-422 and RS-485 signals, each rated for up to 1.2Km transmission distance.
What slot and bracket space does the UT-794 need to install?
It fits a standard PCI-Express x1 slot and occupies one full-height expansion bracket.
