  • Page 5: Introduction

    Rev. 1.2E Introduction Valued customer, Thank you for purchasing this device from Meilhaus Electronic. You ha- ve 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.

  • Page 6: Improper Use

    Rev. 1.2E Manual ME-5004 • When using the configuration „pulse generator“ (FO) unused output pins should not be connected.When using the sink driver the outputs are in a high-impedance state, when using the source driver they are connected to ground.

  • Page 7: Scope Of Supply

    Manual ME-5004 Rev. 1.2E Scope of Supply We do, of course, endeavour to supply you a complete product package. Nevertheless, to make entirely sure that your supply is complete, you can check the contents of your package with the help of the following list.

  • Page 8: Features

    Rev. 1.2E Manual ME-5004 Features The plug-on board of type ME-5004 is a opto-isolated digital-I/O boards with bit-pattern detection for the base boards of the ME-5000 series. You can configure individual subdevices alternatively for frequency measu- rement resp. pulse generator on demand (see chapter 4 from page 23).
  • Page 9 • The isolation voltage between the opto-isolated inputs/outputs and PC-ground is 1 kVAC • The opto-isolated digital inputs of the ME-5004 are equipped with an overvoltage protection diode that can discharge voltage pulses to ground for a short period of time.

  • Page 10: System Requirements

    Rev. 1.2E Manual ME-5004 System Requirements The plug-on board requires a base board of the ME-5000 series and occu- pies a free PCI Express or CompactPCI slot however 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).

    Manual ME-5004 Rev. 1.2E Initial Operation Please read your computer manual instructions on how to install new hardware components before installing the board. Software Installation • Installation under Windows The following basic procedure should be used: If you have received the driver software as an archive file please un-pack the software before installing the board.

  • Page 12: Fitting The Plug-On Boards

    Rev. 1.2E Manual ME-5004 Fitting the Plug-on Boards 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.

    (max. 600 W pulse power at a pulse width of 1 ms). 3.3.2 Opto-isolated Outputs The ME-5004 has 16 opto-isolated outputs. The output port is equipped with special driver chips that allow a selection of sink and source via soft- ware. Depending on the application, the user can switch between low- active outputs (sink driver = standard setting) and high-active outputs (source driver) via software.

  • Page 21: External Trigger

    H 3.3.3 External Trigger On the ME-5004 no external trigger inputs are available. However you can monitor the digital inputs on bit-pattern change and bit-pattern compare. As soon as the specified event occurs, an interrupt can be issued and passed directly to the PC. See chapter 4.2 on page 29.

  • Page 22: External Interrupt

    Rev. 1.2E Manual ME-5004 has to be setup in any case. For the frequency measurement inputs this is the ground of the digital input section (GND_DI, pin 15) and for the pulse generator outputs this is the ground of the digital output section (GND_DO, pin 21) The frequency counters and pulse generators are configured via software.

    (usually at the bottom right of the screen), or through the Windows Start menu. The plug-on board of type ME-5004 is a discrete device with two "sub- devices", beginning with the index "0". The functionality of the subde- vices can be specified by the user through selecting a pre-defined configuration.

  • Page 25: Single Operation Mode

    Single Operation Mode Individual values can be read or written in this operating mode. Notes: • The digital-I/O channels direction is determined by the ME-5004 series hardware (opto-couplers). • In power-down state and after switching on the PC all outputs are in a high impedance state.

  • Page 26: Frequency Input/Output

    Rev. 1.2E Manual ME-5004 4.1.2 Frequency Input/Output ME-5004 Before you can use the "Frequency measurement" or "Pulse generator" modes, it is necessary, before opening your application, to run the ME-iDC configuration tool in order to specify the configuration for the corresponding subdevice (see also Table 4 on page 24).

    Rev. 1.2E Manual ME-5004 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] / ×...

  • Page 29: Interrupt Operation

    Rev. 1.2E Interrupt Operation ME-5004 On the ME-5004 board you can monitor the bit-pattern of the 16 digital inputs. Depending on the application you can select one of the operating modes “bit-pattern compare” and “bit-pattern change”. As soon as the first edge that meets the trigger condition arrives, an interrupt is issued and passed directly to the PC.

    Manual ME-5004 Rev. 1.2E 4.2.2 Bit-pattern Compare In the “bit-pattern compare” mode, the bit pattern of digital inputs can be monitored for equality or inequality. The compare bit-pattern of the corresponding subdevice is used as reference. If the state changes from inequal to equal or from equal to inequal, an interrupt is generated (see diagram 14 on page 31).
