PCI Express communication cards

With over 25 years of plug-in card design and manufacturing experience (ISA, PC/104, PCI, PCI Express), TEDIA provides a wide range of industrial communication products.

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

All TEDIA PCIe communication cards provide optical isolated ports. Optional surge arresters can be added to protect isolation barrier against breakdown caused by induced overvoltage. For more information see safety guidelines for preventing overvoltage damage.

All PCI Express communication cards are based on MCS9901CV controller (manufacturer MosChip Semiconductor) or MCS9904CV controller (manufacturer ASIX Electronics Corp.) that provides PCI Express bus interface, four efficient UARTs (similar to the 16C950 standard) with DMA FIFO 2x 128B in one circuit.

PCI-1482E	2	RS-422/485	D-Sub 9	1kV_DC	MCS9904CV (MCS9901CV)	PCIe x1
PCI-1484E	4	RS-422/485	D-Sub 9	1kV_DC	MCS9904CV (MCS9901CV)	PCIe x1

Note: The first generation of cards (discontinued in 2013) was equipped with the MCS9901CV controller (MosChip Semiconductor), the second generation is equipped with the MCS9904CV controller (ASIX Electronics Corp.); both types have almost identical properties.

Software support

Drivers for the following operating systems are available for COM PCIe cards:

Windows 10, Windows 8/8.1, Windows 7, Windows Vista and Windows XP (all 32-bit & 64-bit version)
Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, Windows Server 2008 and Windows Server 2003 (all 32-bit & 64-bit version)
Windows Server 2016 and Windows Server 2019 are not (and will not be) supported

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 (without TEDIA technical support).
