RS422
One of several standards that incorporate balanced line signals into DB connectors. A pair of wires is used to carry each signal. The data is encoded and decoded as a differential voltage between the two lines. (www.sangoma.com)

PCIe Fast Multifunction, Multichannel Counter Board, Optically Isolated, RS-422 Inputs
APCIE-1711-5V-I
The APCIe-1711 board is a fast multifunction and multichannel counter board for the PCI Express bus. The strengths of this board are its wide range of applications and high precision and reliability for industrial applications. With this board you can realise many different applications on the same hardware base. The board is supplied with a pool of functions which provide the user with maximum efficiency yet minimum space and parts requirement. The functions are individually configured for each channel through the supplied software. The flexible programming facilities on this board allow many differentuser applications to be quickly and easily developed and reconfigured as further requirements arise. Thanks to the FPGA board structure, further counting applications canbe realised through software adaptation.

Serial Data Converters
CONV232/485 and CONV232/422
CONV232/485 and CONV232/422 convert between RS-232 communications (as used by the COM1 and COM2 ports standard on most motherboards) and balanced-mode, long distance RS-485 and RS-422 communications. CONV232/485 was designed for use with our REMOTE ACCES line when there is no RS-485 port on your PC, but may also be used in other, similar applications.
