Page 5: Introduction
Introduction 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. Please take the time to carefully examine the contents of the pack- age for any loss or damage that may have occurred during shipping. -
Page 6: Improper Application
As a basic principle, all connections to the board should only be made or removed in a powered-down state of all components. Ensure that no static discharge occurs while handling the board or while connecting/disconnecting the external cable. ... -
Page 7: Features
Features The ME-5810 series PC boards are opto-isolated digital-I/O boards with bit-pattern detection and counters for PCI-Express- and Com- pactPCI-systems. In this user manual “ME-5810” is used for all versions of the cards, whereas “ME-5810A” or “ME-5810B” is used to describe special features of these versions. - Page 8 with a current limiting per channel. If required, the output driver can send an interrupt on overload to the PC. A suitable external source is required to supply the output driv- ers.

Software Support The ME-series is supported by the Meilhaus Electronic Intelligent Driver System (ME-iDS). The ME-iDS is a unique driver system cov- ering different devices and operating systems. It supports Win- dows 2000/XP/Vista and Windows 7, 8.1, 10 and contains a uni-... -
Page 11: Initial Operation
First choose a di- rectory on your computer (e.g. C:\Temp\Meilhaus\ME-iDS). Use the Meilhaus Electronic Intelligent Driver System (ME-iDS) for programming your new data acquisition hardware. For installation and operation of the driver system, please follow the documenta- tion in electronic form included with the software package. - Page 12 1. If the base board is installed, you must first remove it in or- der 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.

Page 13: Power Supply For Pci-Express Models
Power Supply for PCI-Express Models Because of the PCI-Express slot drive’s insufficient current for op- erating the board, an additional supply is required via the PC power supply. For that purpose connect a free “MOLEX” connector of the PC (as used for power supply of drives) with the appropriate termi- nal of the board (see the following diagram). -

configuration of your PC – a total data throughput of up to 30 MS/s is realistic (see also table 6). The programming of the various operating modes is described in chapter 4.1 from page 28. 3.5.1 Opto-Isolated Inputs The ME-5810 has 16 opto-isolated inputs (port A). In combination with a plug-on board ME-5002, 16 further opto-isolated inputs (port C) can be added. -
Page 18: Opto-Isolated Outputs
3.5.2 Opto-Isolated Outputs The ME-5810 has 16 opto-isolated outputs (port B). In combina- tion with a plug-on board ME-5002, further 16 opto-isolated out- puts (port D) can be added. The ME-5810 and ME-5002 output ports are equipped with special driver chips that allow a selection of sink and source via software. Depending on the application, the user can switch between low-ac- tive outputs (sink driver = standard setting) and high-active out- puts (source driver) via software. - Page 19 To supply the sink output drivers, an external power supply has to be connected to VCC_EXT (Pin 10, 20) with sufficient power (de- pending on the application). At full load this means min. 0.8 A for the ME-5810A and min. 1.6 A for the ME-5810B.

Page 20: Source Driver
3.5.2.2 Source Driver Each input port is equipped with two source driver chips of type ISO1H811G; detailed specifications see page 38. The source output drivers are short-circuit-proof and are equipped with a current limiting per channel. The combination of current lim- iting, thermal shutdown, and automatic restart protects the cir- cuitry against overload. -
Page 21: External Trigger
To supply the source output drivers, an external power source has to be connected to VCC_EXT (pin 10, 20), with sufficient power (depending on the application). At full load this means minimum 6 A for the ME-5810A/B. The output voltage U can be calculated Out,H like this:... -
Page 22: Counters
Frequency measurement (FI = “Frequency Input”): 4 independent inputs for measurement of frequency and duty cycle of periodic rectangular signals (max. 300 kHz). 4 further channels can be added using the plug-on board ME-5002. Pulse generator (FO = “Frequency Output”): 4 independent outputs for a periodic rectangular signal up to 3 kHz with a selectable duty cycle. -

has to be in the range of 24…30 V. The counter outputs are equipped with pull-up resistors (R = 4.7 kΩ ). For programming the timers see chapter 4.1 on page 28. 3.7.1 Wiring of the Counters Notes: Output OUT_2 is designed as an “Open Collector” output, i.e. as soon as the output is conducting (logic “1”), the load R connected to ground (GND_EXT). -
Page 24: Pulse Width Modulation
3.7.2 Pulse Width Modulation Pulse width modulation (PWM) is a special application of the coun- ters. With a suitable external wiring a signal with variable duty cy- cle can be generated with the help of counters 0…2. The duty cy- cle can be varied in the range of 1…99 % in steps of 1. -
Page 25: External Interrupt
External Interrupt If required, you can also monitor the bit-pattern of a digital input port. You can select one of the modes “bit-pattern change” and “bit-pattern compare”. 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 operating mode. -

The ME-5810 series base boards are devices with five subdevices, beginning with index “0”.

Page 28: Single Operation Mode
Single: In this mode single values can be read or written. Streaming (only for the versions “S”): In this mode data-I/O is done via FIFO. The timing can either be controlled by a timer and/or external trigger signals. Various trigger options are available which can be defined as start and stop conditions, see chapter 4.2.1 on page 33. -

4.1.1 Digital Input/Output ME-5810 ME-5001 ME-5002 ME-5004 ✔ ✔ ✔ ✔ For input/output of individual digital values the single operation mode is used. The subdevices are defined as follows: subdevice 0 of the ME-5810 always is of type ME_TYPE_DI and subdevice 1 of type ME_TYPE_DO. - Page 30 the ME-iDC configuration tool in order to specify the configuration for the corresponding subdevice (see also Table 4 on page 27). The programming of the frequency measurement and the pulse generator is always done in the single operation mode. The subtype of the subdevices is always ME_SUBTYPE_SINGLE.

Page 31: Frequency Measurement
The time reference is provided by a 66 MHz counter. It is config- ured using the function. A period of 15.15 ns fol- lows from this, and is defined as the smallest unit of time. It is re- ferred to below as "1 tick". The resolution for T and t is therefore 1 tick (see also the specifications on page 38). -
Page 32: Counters (8254)
The first phase of the rectangular signal is "high" by default. By set- ting the ME_IO_SINGLE_TYPE_FO_START_LOW flag it is also possi- ble to start the output with a "low" level. In combination with the plug-on board ME-5002, 4 additional pulse generators (FO_D0…3) are available, addressed as one subdevice. -

Example (see picture 21): By writing the value 0x00800004 Hex as a mask value (see param- eter <iIrqArg> of the function , bit 2 is monitored for a falling 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 inter- rupt status value bit b 23 returns "1". -
