Caution:

The cards are designed for DAQ&C applications and may be used only according to the

manufacturer's recommendations and precautions given in this manual and other general

standards and terms and may be used only such a way, that its failure caused by any reason

will not be dangerous to any person or property.

1.3 Note on the contents of the manual

This manual contains all information related to card features, I/O connectors etc., but does

not include a description of installing and using drivers.

For information about drivers and programming check the dedicated documentation.

1.4 New firmware versions and customer´s firmware

The PCD-810x card is based on a FPGA unified core providing implementation of PCI

Express bus and all peripheral circuitry, e.g. solution that gives maximum control and

supervision over full functionality. High concentration of control algorithms within FPGA

allows to add or modify functions without redesign the board (e.g. firmware with added

special custom features or a build completely new custom firmware).

A simple software utility for user-friendly firmware upgrade is available.

3.1 Introduction

Attention has been focused on achieving a high quality and reliability during the

manufacturing process and attention was also paid to an inspection of the card before

being shipped to you. 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.

3.2 Hardware configuration

The PCD-810x 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).

Check Figure 1 in Appendix of this manual for more information.

3.3 Installation

Important Warning:

While installing the card, please follow the principles for handling the circuits, which are

sensitive to the electrostatic discharge damage. Touch the card carefully only by the edges,

and do not touch the components or metal contacts on the bottom of the card.

The computer must be switched off before the card is installed. Always disconnect the

power supply cord and other cables connected to the PC!

The cards may be stored only in an antistatic wrapper outside of the computer. Failure to

comply with the rules listed above may lead to damage of the sensitive circuits of the card,

or even of the whole computer.

After removing the slot cover plate, plug the configured card into a free slot for expansion

PC cards and fix it in place.

If you plan to use the digital ports DIO1 and DIO2 of standard format card, install the

PCE-16xx series board (not included in the delivery package of the card) into the next

position and connect the flat cables. Similarly, if you plan to use the digital ports DIO0,

DIO1 and DIO2 of low-profile card, install the PCE-8025/LP adaptor board (not included in

the delivery package) into the next position and connect the flat cables.

Note: In the event of any queries, please contact the manufacturer's technical support.

See http://www.tedia.eu for more contact information.

3.4 Location of switches and connectors

See the Appendix, Figure 1 for location of configuration switches and connectors.

3.5 Connector pin assignment

The connector pin layouts are shown in Table 1 through Table 3, the connector pin

assignment is shown in Figure 2 (all in Appendix of this manual).

rev. 12.2015 I - 4

4.1 Introduction

The PCD-810x card provides 24 isolated digital inputs (signal levels depending on the type

of card) and three 8-bit bidirectional digital ports.

All digital inputs (identified as DIN00÷DIN23) use the D-Sub 25 connector located on the

card bracket, three digital ports (identified as DIO0, DIO1 and DIO2) use header type

connectors located at the back edge of the card.

In case of the standard format card (ie. PCT-842x), the DIO0 port is accessed on the card

bracket via adapter cable PCE-8019 terminated with D-Sub 9 connector. Remaining two

ports (ie. DIO1 and DIO2) can be accessed via adapter cable PCE-1620 (card bracket with

D-Sub 9 connector), or other types from the PCE-16xx series adapter boards.

Note: Unlike the adapter cable PCE-8019, the PCE-16xx boards are not included in the

delivery package of the card.

In case of the low-profile format card (ie. PCD-810x/LP) all three ports DIO0, DIO1 and

DIO2 can be accessed via adapter cable PCE-8025/LP (low-profile card bracket with D-Sub

25 connector); there are currently no other option available.

Note: The PCE-8025/LP adaptor board is not included in the delivery package of the card.

The signal direction of DIO port (ie. input or output option) can be selected independ for

each 8-bit port (it is not possible to select direction individually for each of the eight signals

of one DIO port) from the user software.

The port direction and output data after computer is turned on or restarted are stored in the

on-board EEPROM memory and can modify by the software utility (by default, all ports are

set as input).

4.2 Description of digital inputs

All cards of the PCD-810x series contain 24 isolated digital inputs they differ from each

other only by signal levels and input connections.

The PCD-8104 card digital inputs work with HC/HCT/TTL levels and use HCTMOS circuits

providing high input impedance, very low leakage current and protection diodes. The

unconnected state of inputs represents the H logic level generated by pull-up resistors 10

kOhm against a voltage of 5 V, and the inputs can be therefore also used to direct

connecting of floating contacts.

Check the Appendix, Figure 3 for detail information.

The PCD-8105 card digital inputs support 24 V signals level and work with positive polarity

against the common rail (inputs are designed for PNP outputs).

Check the Appendix, Figure 4 for detail information.

Similar to PCD-8105 card, digital inputs of the PCD-8106 card support 24 V signals level, but

work with negative polarity against the common rail (inputs are designed for NPN outputs).

Check the Appendix, Figure 5 for detail information.

4. Digital Inputs and Ports

PCD-8104, PCD-8105, PCD-8106 User Guide

rev. 12.2015 I - 5

4.3 Description of digital ports

Drivers and receivers based on HCTMOS technology were used for digital ports.

In the output mode (ie. driver mode), the HCTMOS circuits provide true 5 V signal levels

with a high output current with low voltage drop and can therefore be used for direct

control of LEDs, optocouplers, or miniature relays (coil parameters 5 V, 500 Ohm).

In the input mode (ie. receiver mode), the HCTMOS circuits provide not only TTL signal

compatibility, but moreover high input impedance, very low leakage current and

protection diodes. The unconnected state of inputs represents the H logic level generated

by pull-up resistors 10 kOhm against a voltage of 5 V, and the inputs can be therefore also

used to direct connecting of floating contacts.

Check the Appendix, Figure 6 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.

4.4 Interrupt logic

The PCD-810x card allows to trigger an interrupt (simultaneously with the timestamp IRQ

generator) by any combination of rising or falling edges of the signals of all digital inputs

and digital ports.
