SUNIX SER5066A 8-port PCI serial expansion card

SKU CH-SM0Q-82DMK

Adds eight RS-232 serial ports via universal PCI with 128-byte FIFO and 16C950 UART up to 115.2Kbps

  • Adds eight RS-232 ports for legacy device connectivity
  • 128-byte FIFO buffer prevents data loss at 115.2Kbps speeds
  • SUN1999 UART controller ensures 16C950 compatibility and reliability
  • Works in 32-bit and 64-bit PCI slots with 3.3V or 5V power
  • Certified CE, FCC, RoHS and Microsoft WHQL for broad OS support

Eight RS-232 ports on one PCI card

The SUNIX SER5066A adds eight independent RS-232 serial ports to a desktop or server through a single universal PCI slot. It uses the on-board SUN1999 UART controller, which is 16C950 compatible and provides a 128-byte FIFO buffer for each channel. Communication speeds reach 115.2 Kbps per port with hardware auto flow control to prevent data loss. The card suits industrial automation, point-of-sale and legacy equipment connectivity.

Check for a free universal PCI slot and OS support

Verify that your motherboard has an available 32-bit or 64-bit PCI slot running at 33 MHz and that the board accepts both 3.3 V and 5 V signalling. The card is compliant with PCI specifications 2.1, 2.2, 2.3 and 3.0, so it fits most legacy and current PCI backplanes. Ensure the operating system is among the supported platforms: Microsoft Windows, Linux or DOS. No external power connector is required.

Ideal for multi-port serial expansion.

This card targets integrators who need eight native RS-232 connections without occupying multiple slots. It is not suited for users who require USB, parallel or Ethernet interfaces, nor for applications demanding throughput beyond 115.2 Kbps per port. Builders without a free PCI slot or those migrating to PCI Express only should consider alternative form factors.

Fragen zu diesem Artikel

Does the SUNIX SER5066A include the cables needed to connect eight RS-232 devices, or must they be purchased separately?

The card provides eight RS-232 ports using a SUN1999 16C950 compatible UART with 128-byte FIFO; connection cables are not included and must be sourced separately.

Which version of the PCI specification does the SER5066A follow, and will it fit both 3.3 V and 5 V slots?

It complies with PCI 33 MHz version 3.0, 2.3, 2.2 and 2.1 and supports both 64-bit and 32-bit slots at 3.3 V and 5 V.

What does the 115.2 Kbps headline speed mean when the card is installed in a working system?

Each of the eight ports can communicate at up to 115.2 Kbps with on-chip hardware auto flow control and ±2 kV ESD protection on all serial signals.
