separately for each channel to compensate for offset and gain.

Achieving the error defined above requires periodical adjustment/calibration.

Note: The output can be loaded with a current of up to 5 mA (ie. 10 V with a load of 2

kOhm), but the current consumption of all outputs is limited to 20 mA in total.

The outputs are short-circuit resistant to AGND.

Note: ESD-X1 option includes Surge Arrester (protection of the isolation barrier).

2.2 Digital ports

Number of ports: three 8-bit bidirectional ports

Operating levels: HC/HCT/TTL

Load impedance of outputs: 500 Ohm min.

Note: Digital bidirectional ports are not protected against overvoltage, stresses outside the

range 0÷5 V will may cause permanent damage.

The digital ports in the output mode are durable to permanent short-circuit against

GND while maintaining the maximum current of the 5V power source (see

paragraph 2.4 General data).

2.3 Interrupt logic

Interrupt sources: timestamp IRQ generator (1÷255 ms),

all digital ports

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 PCA-8x88 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

rev. 12.2015 I - 4

4.1 Introduction

The PCA-8x88 cards offer eight analog outputs together isolated from the computer (ie. all

outputs are created by one isolated circuit block).

All outputs use the D-Sub 25 connector located on the card bracket.

4.2 Description of analog outputs

The analog outputs are controlled by eight D/A converters (alternatively 12 or 16 bits)

allowing the PC program to make single writing the values of the generated signals; the

current firmware does not support block transfer with FIFO memory.

All outputs operate in a single bipolar range ±10 V, if necessary, configurable threshold

limiters can be used and the real operating range can be set individually for each output

(each channel allows to set the minimum and maximum value).

The initial output values and threshold limiters 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 to ±10 V ranges and zero output voltage).

Check the Appendix, Figure 3 for detail information.

4.3 Adjustment and calibration

The analog outputs are calibrated numerically by the card's internal circuits and the card

therefore does not contain any potentiometers or other hardware calibration elements.

After writing the value of the analog output, these data are processed by the procedure…

• the data are compared with the value of the minimum threshold limiter; if the entered

data value is lower (or "more negative") than the value of the limiter, the data is

replaced by the value of the limiter;

• the data are compared with the value of the maximum threshold limiter; if the entered

data value is lower (or "more positive") than the value of the limiter, the data is

replaced by the value of the limiter;

• the data are processed by calibration constants compensating offset and gain of the D/A

converter and amplifiers;

• the data is written to the D/A converter.

Everything mentioned above takes time less than 1 μs.

Each output is equipped with its own set of calibration constants.

The calibration constants are stored in the on-board EEPROM and are automatically

transferred to the calibration circuits after each start or restart. Calibration constants can be

modify by the software utility.

Note: The cards are adjusted/calibrated during production by the manufacturer, for

recalibration contact the manufacturer's technical support for details.

4. Analog Outputs

PCA-8288, PCA-8688 User Guide

rev. 12.2015 I - 5

5.1 Introduction

The PCA-8x88 card provides three 8-bit bidirectional digital ports.

All 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. PCA-8x88), 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. PCA-8x88/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).

5.2 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 4 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.

5.3 Interrupt logic

The PCA-8x88 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 ports.

Figure 3. Simplified schematic of analog outputs.

The schematic shows eight D/A converters (DAC) and eight output amplifiers (OPA).

The output amplifiers are separated from the D/A converters (in the schematics shown by

switches) providing zero voltage at the outputs until the power-up procedure is completed.

All output amplifiers are powered from a single source; the maximum current of each output

must not exceed 5 mA and the total current of all eight outputs together of the current 20 mA.

In addition, the load impedance should not be less than 2 kOhm.

Figure 4. Simplified schematic of DIO ports.

The diagram shows one bidirectional I/O channel.

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

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

signals of one DIO port.
