PCI communication cards

With over 20 years of plug-in card design and manufacturing experience (ISA, PC/104, PCI, PCI Express), TEDIA provides a wide range of industrial communication products.

TEDIA PCI communication cards add extra COM port interfaces to the PC systems equipped with PCI bus. The cards provide RS-232, RS-422 and RS-485 interface standards in various combinations.

Selected PCI communication cards provide optical isolated ports. For more information see safety guidelines for preventing overvoltage damage.

All PCI communication cards are based on the Oxford Semiconductor controller (OX16PCI954 or OXmPCI954) that provides PCI bus interface, four efficient UARTs (16C950 standard) and parallel interface in one circuit.

Main features

Overview - second generation PCI COM cards

The cards of the second generation are suitable for use in 5V PCI bus (common 32-bit PCI bus in most PCs) and 3.3V PCI bus (usually 64-bit PCI buses or PCI-X buses at server motherboards).

Software support

TEDIA InfoCD

The communication PCI cards are supplied together with TEDIA InfoCD, containing system drivers for the following OS:

All drivers mentioned above are available in the Download section.
Limited MS-DOS support (usually requires program modification).
The cards are supported in Linux, kernel v. 2.4 and higher. The RS-485 Flow Control is not supported by default; the support can be added by modifying the ACR register in 8250.c.

OX16PCI954 (OXmPCI954) controller features

The TEDIA PCI bus cards are based on the Oxford Semiconductor controller (OX16PCI954 or OXmPCI954) that provides PCI bus interface, 4 efficient UARTs (16C950 standard) and parallel interface in one circuit.
