Page 9: Installation
Detailed reading of this guide and following the instructions precisely are highly recommended for achieving full quality and to prevent any damage during installation. For further information see manufacturer's website http://www.tedia.eu. Hardware configuration The PCA-84xx card contains a single configuration element - a two-segment DIP switch (the status of this switch can be read by the program to identify multiple cards as CardID value). -
Page 10: Analog Inputs
User Guide Analog Inputs Introduction The PCA-8428 and PCA-8429 cards offer eight analog inputs and the PCA-8428 and PCA-8429 cards offer sixteen analog inputs. Analog inputs are isolated from the computer, the isolation barrier is shared for all analog inputs, resp. it si shared with both analog outputs (ie. all inputs and outputs are solved by one isolated circuit block). - Page 11 Analog Outputs Introduction The PCA-8428 and PCA-8438 cards offer two analog outputs isolated from the computer, the isolation barrier is shared for both analog outputs and all analog inputs (ie. all inputs and outputs are solved by one isolated circuit block).

PCA-8428, PCA-8429, PCA-8438, PCA-8439 User Guide IRC Encoders and Counters Introduction The PCA-84xx cards contain two independent bidirectional counters equipped with programmable input encoders supporting a wide range of operating modes. In addition, each counter is equipped with minimum/maximum detectors ensuring the capture of extremes between two position readings. -
Page 13: Description Of Digital Ports
Check the Appendix, Figure 9 for detail information. Note: Unfortunately, the concept of bidirectional ports does not provide the overvoltage protection available to other ports of PCI/PCIe TEDIA cards. Interrupt logic The PCT-83xx card allows to trigger an interrupt (simultaneously with the timestamp IRQ generator and FIFO memory control circuits) by any combination of rising or falling edges of the signals of all digital ports. -
