1Introduction

Valued customer,

Thank you for purchasing this device from Meilhaus Electronic. You ha­ve chosen an innovative high technology product that left our premises
in a fully functional and new condition.

Take the time to carefully examine the contents of the package for any
loss or damage that may have occurred during shipping. If there are any
items missing or if an item is damaged, contact us immediately.

Before you install the board in your computer, we recommend to read
this manual carefully, especially the chapter describing board installation.

1.1 Important Notes

1.1.1 Intended Use

The plug-on boards of the ME-5000 series require a base board of the
ME-5000 series and will be plugged onto these and extend the functio­nality of the base boards. Depending on the PC platform the plug-on
board needs an additional:

• … free PCI Express slot (PCIe) or

• … free CompactPCI slot (cPCI),

however without using the PCI slot connector.

Please follow the instructions of chapter 2.3 on page 12 of this document
and the manual of your computer for the procedure when fitting additio­nal hardware componets.

Observe the following notes and specifications starting on page 29:

• Make sure that heat can be dissipated from the board well enough in­side the PC housing.

• Unused inputs must always be connected to the reference ground of
their subdevice, in order to avoid crosstalk between the input
channels.

• When using the configuration „pulse generator“ (FO) unused output
pins should not be connected.

Rev. 1.1E Manual ME-5001

Introduction Page 6 Meilhaus Electronic

• Note that the computer must be switched on first before any voltage
is applied to the board through external circuitry.

• Connecting or disconnecting any of the the board's connectors must
always be done when all the components are powered down.

• Make sure that when touching the board, or when plugging in the
connecting cable, it is not possible for static discharges to pass
through the board.

• Ensure that the connecting cable is securely seated. The plug must be
fully inserted into the D-sub socket, and secured using both screws.
Only in this way can the board be expected to function properly.

1.1.2 Improper Use

Plug-on boards must never be operated outside the PC. Never connect
the devices to electrically live parts, and particularly not to any that carry
mains voltage.

Make sure that the external circuitry connected to the device cannot
come into contact with electrically live parts. Connecting or disconnec­ting any of the the connectors must always be done when powered down.

1.1.3 Unforeseeable Misuse

The device is not suitable for use as a child's toy, for domestic purposes
or under adverse ambient conditions (such as in the open air). The user
must take appropriate precautions to avoid unforeseeable misuse.

Manual ME-5001 Rev. 1.1E

Meilhaus Electronic Page 7 Introduction

1.2 Scope of Supply

Rev. 1.1E Manual ME-5001

Introduction Page 8 Meilhaus Electronic

1.3 Features

The plug-on board of type ME-5001 is a 48 bit digital I/O board with
bit-pattern detection for the base boards of the ME-5000 series. You can
configure individual subdevices alternatively for frequency measurement
resp. pulse generator on demand (see chapter 4 from page 21).

Overview:

*Alternative configuration can be activated via ME-iDC.

• Digital I/O ports: The ME-5001 has totally 48 bi-directional I/Os.

The direction can be defined for each of the six 8 bit ports
(subdevice 0..5) by software. After powering up, all the ports are
configured as inputs.

• Frequency counter: The concept of the "configurable subdevices"

allows subdevice 0 to be employed as a frequency counter. Eight inde

­pendent channels are available for measuring the frequency and duty
cycle of rectangular signals (max. 5.5 MHz).

• Pulse generator: The concept of the "configurable subdevices"

allows subdevice 1 to be employed as a rectangular wave generator.
Eight independent channels are available for the output of a periodic,
rectangular signal at up to 5.5 MHz with a variable duty cycle.

• Signal level 3.3 /5 V: The signal level of all the digital inputs/outputs

and of the control lines can be switched together between 3.3 V and
5 V, depending on the external circuitry. The changeover is made for
all the ports of the plug-on board at once using software.

• For optimum signal matching, you are able to activate, via software,

an active 110 Ω termination at the digital inputs/outputs of the
subdevices 0..3.

Meilhaus Electronic Page 9 Introduction

• Bit-pattern detection: The bit-pattern of a digital input or output

port can be monitored if required. Depending on the configuration,
an interrupt can be triggered in response to a change in the bit-pat­tern.

Thanks to the DMA architecture, the data can be transferred very quickly
between the PC's working memory and the board. In streaming mode,
an input/output rate of up to 30 MS/s, in which all the ports must par

­ticipate, is possible. (See also table 2 on page 22). The actual transmission
rate will depend on the operating mode and the configuration of your
computer.

Depending on requirements, you can select from the following operation
modes:

• Single: In this operating mode, a single value can be read or written

under software control (see chapter 4.1.1 on page 23).

• Interrupt: For interrupt handling in the "bit-pattern change" mode

(see chapter 4.2 on page 27).

Customer-specific versions of the firmware are available on request.

1.4 System Requirements

The ME-5001 requires a base board of the ME-5000 series and occupies
a free PCI Express or CompactPCI slot but without using the PCI slot
connector. This saves the resources of your PC. The board is supported
by the Meilhaus Intelligent Driver System (ME-iDS) from Windows
2000 upwards (Linux under development).

1.5 Software Support

The plug-on boards of the ME-5000 series are supported by the
Meilhaus Intelligent Driver System (ME-iDS). The ME-iDS is a unified
driver system usable across devices and operating systems. It supports
Windows 8/7/Vista/XP/2000 (Linux under development) and contains
a universal function library (API) for programming.

You will find a detailed description of the functions in the ME-iDS
manual, a copy of which is on the CD/DVD supplied.

Please also observe the notes in the appropriate README files.

2.3 Fitting the Plug-on Board

The boards should be handled with care in order to make sure that the
device is not damaged by electrostatic discharge (ESD), mechanical stress
or unsuitable current surges. Precautions should also be taken to avoid an
electric shock. Ensure that standard ESD safty precautions are taken. At
least one hand should be grounded in order to dissipate any static charge.

Observe the following procedure:

1. If the base board is installed, you must first remove it in order
to be able to insert the plug-on board. Here you should
observe the procedure as described in the manual for your PC
system.

2. Make sure that electrostatic discharges cannot take place
through the plug-on board or the base board as you plug it in.
Follow the standard ESD safty precautions.

3. Push the plug-on board carefully, and with only a little force,
on to the male connector provided for it (see diagram

1, items

1, 2 and 3). Check that the board is fully plugged in.

4. Choose two adjacent slots for the installation. If necessary,
remove an additional mounting bracket for the slot of the
plug-on board.

5. Carefully plug the combination of the base and plug-on board
into the computer.

6. Screw the two slot brackets down firmly.

7. Close the PC system again.

3.3.1 Digital Inputs

When wiring the inputs, note that the voltage level must be observed (see
the specifications on page 29) and that a reference to the PC ground
(GND_PC) must be established (see diagram 4).

3.3.2 Digital Outputs

When wiring the outputs, note that the voltage level must be observed
(see the specifications on page 29) and that a reference to the PC ground
(GND_PC) must be established (see diagram 4).

3.3.3 External Trigger

On the ME-5001 no external trigger inputs are available. However you
can monitor the bit-pattern of a digital input port. As soon as the
specified event occurs, an interrupt can be issued and passed directly to
the PC. See chapter 4.2 on page 27.

3.4 Frequency Input/Output

The concept of the "configurable subdevices" of the ME-5000 series
gives you the option of using individual subdevices with an alternative
functionality. The associated configuration is carried out with the
ME-iDC configuration tool before your application is called.

The following channels are available:

• Frequency measurement (FI= "Frequency Input"):
8 independent inputs for measuring the frequency and duty cycle of
rectangular signals (max. 5.5 MHz).

• Pulse generator (FO= "Frequency Output"):
8 independent outputs for the output of a periodic rectangular signal
at up to 5.5 MHz with a variable duty cycle.

The associated pins are identified as FI_0..7 and FO_0..7 in the terminal
assignment on page 11. After powering up, the pins FO_0..7 are configu­red as inputs i. e. in high impedance state. Not until the driver has been
loaded driver become conductive.

Manual ME-5001 Rev. 1.1E

Meilhaus Electronic Page 19 Hardware

Diagram 5: Wiring the frequency inputs/outputs

The specifications for the digital I/O ports apply to the wiring of the
FI/FO lines. A reference to the PC ground (PC_GND) must always be
established. The maximum output current is I

Out

= IOL = IOH = 24 mA.

The frequency counters and pulse generators are configured by software.
Please read chapter 4.2 on page 27 for programming the frequency in­put/output.

3.5 External Interrupt

If required, you can also monitor the bit-pattern of the digital inputs.
The "bit-pattern change" mode is available on the ME-5001. As soon as
the specified event occurs, an interrupt is issued and passed directly to the
PC.

The digital inputs/outputs are programmed in the single operation
mode. The interrupt handling is carried out with the meIOIrq… func

3.6.1 Termination

For optimum signal matching, you can enable via software, an active
110 Ω termination at the digital inputs/outputs of the subdevices 0..3.

The termination circuits are effectively protected against overload by the
combination of current limiting and thermal shutdown (with automatic
return to service).

3.6.2 Logic Level Matching

The signal level of subdevices 0..3 can be switched together between

3.3 V and 5 V, depending on the external circuitry. The changeover for

the pins DIO_0..31 is made in common by software.

Manual ME-5001 Rev. 1.1E

Meilhaus Electronic Page 21 Programming

4Programming

The Meilhaus Intelligent Driver System (ME-iDS) is included with the
ME-5001 for programming purposes. The ME-iDS is a unified driver
system usable across devices and operating systems. It supports Windows
2000 and above, as well as Linux systems (in preparation) with Kernel 2.6
and above, and contains a universal function library (API) for all
common programming languages. (You can find the scope of the current
software support in the readme files of the ME-iDS.)

A detailed description of the functions can be found in the ME-iDS
manual (see the CD/DVD included with the board, or online under:
www.meilhaus.com/download). Other details, such as the assignment of
the subdevices and device-specific arguments, may be found in the help
file (in the help file format under Windows, *.chm), which you can open
via the "ME-iDS Control Center" in the information area of the taskbar
(usually at the bottom right of the screen), or through the Windows Start
menu.

The plug-on board of type ME-5001 is a discrete device with six "subde­vices", beginning with the index "0". The functionality of the subdevices
can be specified by the user through selecting a pre-defined configura­tion. The desired configuration is loaded into the board by the ME-iDC
configuration tool before your application starts. Using the standard
configuration, (ID 0), the board is ready to operate immediately. You will
find an overview of the currently available configurations in the following
table:

Subdevice-Konfigurationen ME-5001

*Standard configuration at shipment. The most recently selected

configuration in the ME-iDC is stored in a non-volatile memory on the
board, and is automatically loaded after a restart.

Depending on requirements, you can select from the following
operation modes:

4.1 Single Operation Mode

Individual values can be read or written in this operating mode.

Notes:

• In the single operating mode, all subdevices of the ME-5001 can be
used bidirectionally.

• After powering up, the bidirectional ports are configured as inputs.

• A port that is configured as an output can also be read back!

4.1.1 Digital Input/Output

The input/output of individual digital values is carried out in the single
operating mode. All subdevices are of type ME_TYPE_DIO, subtype
ME_SUBTYPE_SINGLE. The configuration is done separately for each
subdevice.

4.1.2 Frequency Input/Output

Before you can use the "Frequency measurement" or "Pulse generator"
modes, it is necessary, prior calling your application, to run the ME-iDC
configuration tool in order to specify the configuration for the corres­ponding subdevice (see also table 2 on page 22).

The programming of the frequency measurement and the pulse generator
is always done in the single operating mode. The subtype of the subde­vices is always ME_SUBTYPE_SINGLE.

Diagram 7: Frequency input/output in single operation mode

Please read the ME-iDS manual and the ME-iDS help file (*.chm)
carefully prior to programming. You can open both of these documents

through the "ME-iDS Control Center or through the Windows Start
menu.

Two variables are introduced to describe the rectangular signal, and apply
equally to input and output. One value indicates the period T, while the
other value provides the duration of the pulse of the first phase of the
period t1P. For frequency measurement, the measurement starts with the
first rising edge, and finishes with the next rising edge. The falling edge
that lies between them defines the end of the first phase. In pulse genera­tor mode, output normally starts with a high level, changing to the low
level when the first phase has elapsed.

Diagram 8: Signal definition

The time reference is provided by a 66 MHz counter. It is configured
using the meIOSingleConfig() function. A period of 15.15ns follows from
this, and is defined as the smallest unit of time. It is referred to below as
"1 tick". The resolution for T and t1P is therefore 1 tick (see also the
specifications on page 29).

Note that the value of the maximum period T

max.

depends on the duty
cycle. A distinction is drawn between rectangular signals with an asym­metrical duty cycle T

max. asym.

and a symmetrical duty cycle T

max. sym.

.

The figures for the ME-5001 are:

T

= 65 s (0.015 Hz)

The wiring of the frequency inputs/outputs can be found in chapter 3.4
on page 18.

4.1.2.1 Frequency Measurement

With the frequency measurement operating mode (FI= "Frequency In­put") you can determine the period or frequency, and the duty cycle of
rectangular signals up to about 5.5 MHz. The resolution is 1 tick =

15.15 ns. The measurement always starts at a rising edge. On the
ME-5001, all 8 frequency measuring channels (FI_0…7) are addressed
as subdevices of type ME_TYPE_FI, subtype ME_SUBTYPE_
SINGLE. Each channel can be programmed independently.

Note: If the frequency and duty cycle are the magnitudes you want, these
can easily be calculated from the values returned for <pdTime>. The
formula is:

Frequency [Hz] = 1/period [s]

Duty cycle [%] = ("duration of the first phase of the period" [s] /
period [s]) × 100

4.1.2.2 Pulse Generator

In the pulse generator operating mode (FO = "Frequency Output") you
can output rectangular signals with a variable duty cycle at frequencies of
up to 5.5 MHz and with a resolution of 1 tick. On the ME-5001, all 8
pulse generator channels (FO_0…7) are addressed as subdevices of type
ME_TYPE_FO, subtype ME_SUBTYPE_SINGLE. Each channel can
be programmed independently.

The first phase of the rectangular signal is "high" by default. By setting
the ME_IO_SINGLE_TYPE_FO_START_LOW flag it is also possible
to start the output with a "low" level.

All the pulse generator channels can be started synchronously or inde­pendent form each other.

Note: An output channel can also be read back!

4.2 Interrupt Operation

On the ME-5001 you can monitor the bit-pattern of a subdevice
configured as an input for changes in one or more masked bits. As soon
as the first edge that meets the trigger condition arrives, an interrupt is
generated and passed directly to the PC.

The programming the digital input/output is carried out in the single
operation mode. The subdevice must be of type ME_TYPE_DIO. The
interrupt handling is done by the meIOIrq… functions.

Diagram 9: Interrupt options

Please observe the ME-iDS manual and the ME-iDS help file (*.chm) for
the

procedure. You can open both of these documents through the

"ME-iDS Control Center“ or through the Windows Start menu.

4.2.1 Bit-pattern Change

In the bit-pattern change mode, one or more bits that are to be monito­red for a change of state can be defined (masked). A 32-bit wide
argument per subdevice contains the mask. For each input pin both one
bit for rising edge and one bit for falling edge are available. If the state of
at least one bit masked with a "1" changes (0 → 1 or 1 → 0), an interrupt
is issued (see diagram 10 on page 28).

Programming Page 28 Meilhaus Electronic

In what is known as the "extended format" of interrupt handling (see the
ME-iDS manual), two bits are available for the interrupt status of each
pin. One is for the rising edge, and one for the falling edge. The bits for
the falling edges are assigned to the bit b7…0, while the bits for the rising
edges are assigned to the bits b23…16.

Diagram 10: Bit-pattern change

Example (see diagram 10):
By writing the value 00800004Hex as a mask value (see parameter

<iIrqArg> of the function meIOIrqStart()), bit 2 is monitored for a fal-

ling edge, and bit 7 for a rising edge. A rising edge now is to arrive at bit 7,
so that an interrupt is issued and in the interrupt status value bit b23
returns "1". Any edges that might arrive at pins labelled with an "X" are
ignored. Only the change in state of a pin whose edge is set to "1" in the
parameter

<iIrqArg> can issue an interrupt.

The interrupt event is evaluated with the function meIOIrqWait(). We
recommend using what is known as the "extended format" to obtain
detailed information about the triggering edge.
