Two 16550 Serial Ports via PCI
This card adds two 9-pin RS-232 ports to a desktop through a 32-bit PCI slot. It targets industrial and POS users who need to connect legacy serial devices such as barcode scanners, displays or modems. The 16550 UART with 32-byte FIFO buffers supports data rates up to 230 Kbps. Both standard and low-profile brackets are included for flexible case mounting.
Replaces Onboard or Single-Port Serial
Upgrading from a single onboard COM port or a one-port expansion card is worthwhile when two simultaneous serial links are required for data gathering or point-of-sale equipment. The jump also makes sense when 5 V or 12 V power output on the ports is needed for peripheral operation without extra adapters. Systems lacking any native serial header benefit immediately.
Sustained Operation with IRQ Sharing
Built-in IRQ sharing reduces conflicts during continuous multi-port communication, while the 32-byte FIFO buffers maintain throughput under steady load. The card operates in 3.3 V or 5 V PCI and PCI-X slots, supporting Windows 95 through Server 2003 for long-term deployment in legacy environments. FCC Class B and CE compliance ensures stable electromagnetic behaviour.

Questions about this item
Which brackets are included for mounting the card in a standard or low-profile case?
The card ships with both standard and low-profile mounting brackets so it can be installed in almost any chassis.
What is the most common mistake when installing the card in a 32-bit PCI slot?
Forgetting to attach the mini fan-out cable to the card before securing the bracket leaves the serial ports inaccessible.
Will the 16550 UART ports need any firmware updates or capacitor replacements over time?
No firmware or capacitor maintenance is required; the ports operate as standard RS232 interfaces for the life of the card.
