Product identity

The TeKit IO-PIO1058-8S is an 8-port RS232 PCI expansion card built around the SYSBASE 1058 chip. It adds eight DB9 serial connections through a single PCI slot for industrial control, POS, ticketing and legacy equipment.

Compatibility check

Verify that the host system has a free PCI slot and runs one of the listed operating systems such as DOS, Linux 2.4 or 2.6, Windows 98, 2000, XP 32/64, 2003, Vista, 2008, 7 or 8. The card uses automatic IRQ and I/O assignment with PCI IRQ sharing and requires no jumpers or switches.

Sustained operation

Each port provides a 256-byte FIFO buffer and supports data transfer rates up to 926.1K bps. The PCI 2.3 compliant design handles continuous multi-port communication for automation, LED control, engraving machines and telephone billing systems without manual configuration.

Questions about this item

Does the card ship with the eight DB9 cables shown in the description, or must they be purchased separately?

The package contains one card only; the eight DB9 cables are not included and must be sourced separately.

Which PCI revision does the SYSBASE 1058 chip comply with, and does it matter for my motherboard?

The card meets PCI Revision 2.3, so it will work in any standard 32-bit or 64-bit PCI slot without jumpers or switches.

What does the 926.1 Kbps headline rate mean when all eight ports are active simultaneously?

Each port has a 256-byte FIFO buffer and the chip shares a single PCI IRQ, so the 926.1 Kbps is per-port maximum; aggregate throughput depends on system load and driver efficiency.
