Eight-Port RS-232 Expansion for Industrial

The UOTEK UT-758 adds eight RS-232 serial ports to a desktop PC or server through a single universal PCI slot. It targets integrators building POS, ATM or factory-automation systems that still rely on legacy serial equipment such as modems, printers, scanners or PLCs. The card operates on both 3.3 V and 5 V PCI buses, so it fits a wide range of existing hardware platforms.

Straightforward PCI Installation

Insert the card into any 32-bit universal PCI slot and attach the single DR62 female connector; an external octopus cable (not included) then splits the eight ports to standard DB9 devices. The main installation issue is sourcing a quality DR62-to-8×DB9 cable that maintains signal integrity for all ports. Driver support covers Windows 2000 through 10, Linux 2.4.x and 2.6.x, VxWorks and several embedded Windows CE releases.

Consistent Throughput Across All Ports Under

Each port sustains selectable baud rates from 300 bps up to 921.6 kbps with hardware RTS/CTS and software XON/XOFF flow control. The ±15 kV ESD protection on every line helps prevent data errors when long cables run near heavy machinery. Operating temperature is rated from -40 °C to 85 °C, allowing the card to keep performing in unconditioned cabinets during extended production shifts.

Questions about this item

How do I verify the UT-758 card is functioning after installation?

Open Device Manager in Windows or run dmesg on Linux; eight new COM ports should appear. Loopback pins 2 and 3 on a DB9 connector and send data at 921.6 kbps to confirm each port transmits and receives.

What ships with the UT-758 and what must I source separately?

The box contains the PCI card with its DR62 female connector. You must obtain a DR62-to-8×DB9 breakout cable or panel to access the eight RS-232 ports.

Which UT-758 variant suits a 3.3 V PCI slot versus a 5 V slot?

The single UT-758 model supports both 3.3 V and 5 V universal 32-bit PCI buses, so no version choice is needed; one card fits either voltage.
