1 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
package for any loss or damage that may have occurred during
shipping. If there are any items missing or if an item is damaged,
please contact us immediately.
Before installing the board in your computer, we recommend you
read this manual carefully, especially the chapter describing board
installation.
The descriptions in this manual concern PCI-, PCI-Express- and
CompactPCI-versions of the ME-9000 series, if not otherwise
noted.
1.1 Important Notes
1.1.1 Use in Accordance with the Requirements
The PC boards of the ME-series are designed for acquisition and
output of analog and digital signals with a PC. Depending on type
install the models of the ME-series into:
a free PCI slot or
a free PCI Express slot or
a free CompactPCI slot.
The boards of the ME-90 PC/104-Plus series are serial interface
boards (RS-232 or RS-422/485) in the PC/104 format to be
integrated in a PC/104-Plus stack.
For information on how to install a plug-in board or connect a USB
device, please read the manual of your PC.
Please note the instructions and specifications as presented in
this manual (Appendix A, Specifications):
Please ensure sufficient heat dissipation for the board within
the PC housing.

All unused inputs should be connected to the ground reference
of the appropriate functional section. This avoids cross talk
between the input lines.
The opto-isolated inputs and outputs achieve an electrical
isolation of the application relative to PC ground.
Note that the computer must be powered up prior to
connecting signals by the external wiring of the board.
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.
Ensure that the connection cable is properly connected. It
must be seated firmly on the D-Sub connector and must be
tightened with both screws, otherwise proper operation of the
board cannot be guaranteed.
1.1.2 Improper Application
PC plug-in boards for the PCI-, PCI-Express- or CompactPCI-bus
may not be taken into operation outside of the PC. PC/104-Plus
boards may not be taken into operation outside of an embedded
system. Never connect the devices with voltage-carrying parts,
especially not with mains voltage. As power supply of the USB
models only an authorized power adapter may be used.
Make sure, that no contact with voltage-carrying parts can happen
by the external wiring of the device. As a basic principle, all
connections should only be made or removed in a powered-down
state.
1.1.3 Unforeseeable Misapplications
The device is not suitable to be used as a children’s toy, in the
household or under unfavourable environmental conditions (e.g. in
the open). Appropriate precautions to avoid any unforeseeable
misapplication must be taken by the user.

The ME-9000 series is a high integrated serial interface board
designed for PCI-, PCI-Express- resp. CompactPCI-bus. It provides
a PCI controller with integrated Octo-UART of type EXAR
XR17D158IV for extended temperature range. The UARTs are
register-compatible with the 16550 and provide an integrated 64-
byte transmit and receive FIFO for each port. The board allows
transfer rates up to 921,6 kBd. There are versions available with
up to 8 ports for RS-232 and/or RS-422/485 standard. The ME-
9000 PCI- and cPCI-versions adapt themselves automatically to
the level at the PCI bus of +3.3 V or +5 V (Universal PCI).
As a special the ME-9000 offers an 8-bit multi-I/O port for
customer-specific extensions. See also chapter 4.1 "ME-9000
Multi-I/O Driver" from page 61 on.
The ME-9000i models provide opto-isolation of all serial ports from
PC ground. I.e. as seen from the application all ports refer to a
common, isolated ground (GND_C). The isolation voltage is 500 V.
ME-9000p models: each serial port is an electrically isolated
„island“ with separate ground (GND_x). It is ideal for noise-
sensitive environments in industrial control. The isolation voltage is
500 V.

The ME-90 PC/104-Plus series is a serial interface board com-
pliant to PC/104-Plus specification 2.3 with PCI interface (3.3 V or
5 V) and a „looped through“ ISA bus. I.e. if you have a PC/104-Plus
single board computer, which supports PCI- as well as ISA-bus you
can combine the ME-90 PC/104-Plus with ISA-based PC/104
boards without problems.
The ME-90 PC/104-Plus provides a PCI controller with integrated
Octo-UART of type EXAR XR17D158IV for extended temperature
range. The UARTs are register compatible with the 16550 and
provide an integrated 64-byte transmit and receive FIFO for each
port. The board allows transfer rates up to 921,6 kBd. There are
versions available either with 8 RS-232, 8 RS-422/485 or mixed
with 4 RS-232 and 4 RS-422/485 ports. The routing of the PCI-
bus signals CLK, IDSEL and INT0# is done by jumpers. The ME-90
PC/104-Plus adapts itself automatically to the level at the PCI-bus
of +3.3 V or +5 V (Universal PCI).
With its extended temperature range from -40 °C to +85 °C it is
the ideal solution for industrial applications.
As a special the ME-90 PC/104-Plus offers an 8-bit multi-I/O port
for customer-specific extensions. See also chapter 4.1 "ME-9000
Multi-I/O Driver" from page 61 on.

2 Installation
Important Note:
If you have got the driver software as an archive file (e.g. by
download or the Windows 9x driver coming with CD/DVD), please
unpack the software before installing the board to a directory of
your choice.
Now insert the board into your computer (see chapter „Hardware
Installation) and then install the driver software (see chapter
„Driver Installation“). This order of operation is important to
guarantee the “Plug&Play”-operation under Windows*
95/98/Me/2000/ XP and Vista. Windows NT 4.0 needs an analogous
order of operation, however the installation procedure differs
slightly.
2.1 Hardware Installation
The following chapter also applies to the installation of PC/104
(-Plus) boards.
Please read your computer’s manual instructions on how to install
new hardware components.
Basically use the following procedure for installing the board.
Make sure that the computer is turned off.
Caution: some of the more sensitive components can be damaged
by static electricity!
That’s why: Make sure to ground yourself by touching an
exposed metal part of the PC case before handling the board.
Unplug the power cable from your computer.
Open the computer case.
Pick up your board carefully with both hands. Be careful not to
bend the board or to damage the edges in any way. This could lead
to short-circuits on the board. Do not exert too much pressure
when inserting the board into the slot. A small amount of force

should be all that is required to seat the board fully and properly
into the slot.
Close the computer case.
Connect the power cable to your computer.
Power up your computer and continue with the chapter
“Driver Installation”.
2.2 Driver Installation
2.2.1 Unpacking the Driver Software
Proceed with the following steps if you have got the driver update
as a self-extracting archive (e.g. by download or the Windows 9x
driver coming with the CD/DVD, if supported by the regarding
model). Else you can start directly with the driver installation (see
the following chapters).
Navigate to the appropriate archive file (e.g.
<Drive>:\InstallWindows\Serial\me-9x00\win9x\
me9x00vxd.exe) and unpack the driver software by
double-clicking the archive file.
Enable the option „Overwrite Files Without Prompting“
(default)
Only Windows NT 4.0: enable the option „When Done
