Industrial 8-Port PCI Serial Card

The UOTEK UT-768I adds eight RS-232 ports through a single 32-bit universal PCI slot. It targets industrial automation, POS and ATM systems that must connect multiple legacy serial devices such as modems, printers or scanners to a modern motherboard.

HDR78 Breakout with Opto-Isolation

A single HDR78 female connector carries all eight channels, each protected by a dedicated DC/DC isolation module rated at 2500 Vrms. The card operates on both 3.3 V and 5 V PCI buses, freeing the builder from voltage-matching concerns while the ±15 kV electrostatic protection shields connected equipment.

Sustained Operation Across Extreme Temperatures

Rated for continuous use from -40 °C to 85 °C, the card maintains stable throughput up to 921.6 kbps per port with full hardware flow control. Opto-isolation prevents ground-loop noise from degrading data integrity during long cable runs in electrically noisy factories or outdoor kiosks.
