PCIe-BASE
Data Acquisition and Control Card (PCIe)
Measurement & Control.
Multifunctional.
Stationary measurement data acquisition in
latest "PCI Express" technology: The PCIe-
BASE is a multifunctional data acquisition and
control card. Its modular structure guarantees
individual and flexible adjustment to a
measuring task.
Modular Concept. Optimize
Price-Performance-Ratio.
Perfectly adapted to the respective
measurement application, data acquisition
modules can be selected to equip the two
module slots of the
PCIe-BASE. It is the customer who decides
about performance and price of his DAQ
system!
Modules: MADDA. MDA. MCAN.
What Would You Like?
A great variety of analog plug-on modules is
available differing in the number of inputs and
outputs, resolution and sampling rate. If a
MADDA module e.g. is combined with a CAN
module, analog measurements and via the
CAN interface are possible. Analog, digital,
and CAN channels are sampled time-
synchronously.
32 Digital I/O. 3 Counters.
The PCIe-BASE features 32 digital lines, which
means that the base board is a digital I/O card
itself. The direction of the two 16-bit ports is
set via software. 3 counters accessible via any
digital inputs allow the acquisition of counting
pulses or the connection of incremental
encoders.
PCIe. Be on the Cutting Edge.
Designed in "PCIe x1" format, the PCIe-BASE
can be installed in any PCIe slot. In the long
term, this extremely powerful interface will
completely replace the predecessor "PCI" in
the PC. Due to Plug&Play, the card is
recognized automatically by the PC making
installation a lot easier.
Windows®. That's it.
The PCIe-BASE can be used on Windows®
XP/7/8/10. The entire software for installation
and programming of the multifunction card is
included for free.
NextView®. Try for Free.
The DAQ system is supported by NextView®,
the software for data acquisition and analysis.
A fully functional 14-day trial is included with
delivery to directly test the functionality of the
PCIe-BASE.

2.2 Module Slots M1 and M2
The channels of the module slot M1 are available at
the 37-pin D-Sub connector as well as at the pin
connectors K1, K2.
The connections of the second module slot M2 are
accessible at the pin connectors K3, K4.
With the optional accessory ZUKA16 (see chapter
5), the channels of the module slot M2 are lead out
to an additional D-Sub 37 female connector (connect
line 1 - colored - of ZUKA16 with pin 1 of the pin
connector K3 - square pad - and attach 2. connector
in parallel to K4).
The figure below shows the pin assignment of the
module slots M1 and M2 of the PCIe-BASE:

Seite 5
2.2.1 Current Measurement
Analog input modules (MADDA) installed on module slot M1 can be also
used for current measurement. To install current shunts (e.g. ZU-CS250R)
at the 20-way pin connectors K1 and K2, connect the pin of the relating
analog input with the opposite ground pin by a resistor (current shunt).
2.2.2 Lead Connections from M2 to D-Sub37
By closing the solder bridges PL400-403 and PL406-409 and
opening PL 410-414 on the bottom side of the PCIe-BASE
board, the first four channels of an analog module (MADDA or
MDA series) mounted on slot M2 are led to the free pins of the
37-pin D-Sub female to be available from the outside.
•Channels of MCAN modules cannot be reached in that way at
the D-Sub37 female connector!
•The corresponding ground pin for the analog channels of the M2 module slot is exclusively
available at pin 17 of the D-Sub 37.

3Digital Channels
The PCIe-BASE features two digital ports with
16 inputs or outputs each. The lines are
bidirectional. The connections are designed as
two 20-way pin connectors (male) on the board
(see Figure 1, p.3).
Pin connector K6 => port A, line 1..16
Pin connector K5 => port B, line 1..16
•The digital inputs and outputs are protected
by serial resistors!
•At PC start, port A is set to input, port B to
output.
•Digital inputs will always be read
synchronously in time together with the
analog inputs.
•Make sure the digital outputs of the device
do not drive against the outputs of your signals.
With the optional accessory ZUKA16 (see
chapter 5), the digital channels are led to an
additional 37-pin D-Sub female connector
(connect line 1 (colored) of ZUKA16 with pin 1
of the pin connector K5 (square pad), attach 2.
connector in parallel to K6).
The right figure shows the connection of the pin
plugs K5, K6 with the D-Sub37 of a ZUKA16.

3.2 Auxiliary Voltage
The PCIe-BASE provides an auxiliary voltage (e.g. for sensor supply) at pin 17, 18 of the pin connector
K5. The 5V DC output (100mA) is protected by a fuse (multifuse). In case of overload, it is sufficient to
interrupt the power supply (turn off PC or disconnect the consumer load). After app. 1 min., the
multifuse will be regenerated.
3.3 Counter
The PCIe-BASE features three 32-bit counters allowing the connection of incremental encoders. The
counter inputs (A, B, and Reset) can be assigned to any digital lines of the two digital ports (configure
by software).
The PCIe-BASE counts the number of incoming pulses (max. 16MHz) sampled at the connection of
signal A. If the maximum counting range is reached, the counter will be reset to the minimum value of
the counting range. If the external counter reset is connected, the counter can be reset at any time.
In comparison to a counter, the quadrature decoder considers the counting direction by decoding a
second phase-shifted signal.
To activate the counting function, the respective digital lines of the PCIe-BASE must be assigned to
the counter via software.

4Interfacing Examples
In the following examples, the signal is always connected at port A, line 1 (pin 11). Before, however,
the relating digital port must have been switched to input (see chapter 4.1) or output (see chapter
4.2).
4.1 Interfacing Examples for Digital Inputs
The 3.9kpull-down resistor sets the input to low if no voltage is applied there.
4.1.1 Connecting an Optocoupler
Optocouplers provide optimum protection at
each input line. With them, it is possible to
connect higher voltages and to protect the
hardware from being destroyed.
In this regard, please also see application
examples of the optocoupler you use.
Optocoupler cards featuring 8 inputs are
available at bmcm.
4.1.2 Connecting a Push-Button /
Switch
Please make sure to use a push-button with
debounce protection, because otherwise
several pulses might be recorded.
The 3.9kpull-down resistor is absolutely
necessary to create a defined low signal!
4.1.3 Connecting a Voltage Divider
If connecting a DC voltage higher than 5V, a
voltage divider must be used so that 5V at the
maximum are applied at the device input.
Exceeding the 5V input voltage might cause
damages to the device.
The relation between the two resistors to be
used is calculated with the following formula:
U/U1= (R1+R2)/R1
Input voltages less than 5V are also sufficient
(high 3V).

PCIe-BASE
Seite 10
4.1.4 Connecting a Counter /
Incremental Encoder
The connection of "Signal A", "Signal B" and
"Reset" is possible at any digital line.
Make sure to configure the relating digital lines
as input and to assign them to the counter.
4.1.5 Connecting an LED
Only so-called low-current LEDs can be used,
because they already work with 1mA current.
Please also observe the total current listed in the
technical data (see chapter 7).
4.2 Interfacing Examples for Digital Outputs
Serial resistors in the output lines limit the current and protect the hardware from being destroyed.
4.2.1 Connecting a Relay
A connected relay is ideal to switch higher
currents. Since the field coil of the relay requires
a higher current than provided by the
measurement system at one line, a transistor is
connected ahead.
Relay cards featuring 8 outputs are available at
bmcm.

PCIe-BASE
Seite 11
4.2.2 Connecting a Lamp
A transistor can be used to switch higher loads.
The selected transistor must comply with the
maximum switchable current.
The figure on the right shows an application with
a maximum current of 100mA.
5Connection Cable ZUKA16
Via a flat ribbon cable, the optionally available connection cable
ZUKA16 leads the channels provided at two 20-way pin connectors
each to a 37-pin D-Sub female connector with bracket, which is
mounted at a free PC slot.
With the ZUKA16, the channels provided by module slot M2 (see
chapter 2.2) and the digital lines of the PCIe-BASE (see chapter 3) can
be reached externally.
The line of the flat ribbon cable leading to pin 1 of the D-Sub37 is
colored.

6Important Notes for Using the PCIe-BASE
•The device is only suitable for extra-low voltages - please observe the relevant regulations! Only use the card
with PC housing closed. ESD voltages at open lines may cause malfunction.
•Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free.
•Signal cables are connected at the 37-pin D-Sub female connector –preferably use shielded cables. For best
possible interference suppression, connect shield at one end only. Close open inputs if necessary.
•The device must not be used for safety-relevant tasks. With the use of the product, the customer becomes
manufacturer by law and is therefore fully responsible for the proper installation and use of the product. In the
case of improper use and/or unauthorized interference, our warranty ceases and any warranty claim is
excluded.
•Improper installation of the modules on the PCIe-BASE may damage the modules and/or the PCIe-BASE.
When removing the modules, only use blunt tools! Exposing the card to strong vibrations requires additional
protection of the modules.
•If connecting internal ribbon cables to the PCIe-BASE, please make sure the modules are well ventilated to
prevent excess heating. Also observe the temperature ranges of the PC.
•In case of overload, interrupt the power supply (turn off PC) so that the multifuse on the board is regenerated.
The fuse will be ready for use after app. 1 min.
Do not dispose of the product in the domestic waste or at any waste collection places. It has to be either duly
disposed according to the WEEE directive or can be returned to bmcm at your own expense.
