With the meM-LOG-SE, BMC
Messsysteme GmbH introduces a
data logger, that offers entirely
new possibilities for many measur-
ing applications.
It is a completely self-sufficient
device, which is especially suitable
for long-term measurements.
Unlike a classic data logger re-
cording for a long time but with
very low frequencies, the meM-
LOG-SE reaches
... sampling rates of
up to 100Hz ... .
Equipped with an integrated ac-
cumulator, the meM-LOG-SE can
be placed even in hardly accessible
locations where neither any power
supply nor PC connection is possi-
ble.
So it is no problem, to realize
measuring applications which
require
... mobility and flexibility ...
in a high degree. In order to extend
the operating time of the accumu-
lator, the device changes into an
energy-saving mode after 1 minute
(Sleep Mode) and just "wakes up"
occasionally, e.g. shortly before
scanning the next measuring value.
Via
... 16 analog input channels in
the measuring range of ±5V ...
with a resolution of 12 Bit or via
... 2 digital input
channels (TTL) ...,
the measured signals are written to
the 512kB-size memory. The chan-
nels to be saved can be defined
explicitly.
The scan usually proceeds until the
memory is full. If Loop Mode is
selected, however, the meM-
LOG-SE uses a loop memory
where previous measuring values
are overwritten as soon as the
storage capacity is reached.
In addition,
... alarm values can be set ...
for each channel separately. If
measuring values are beyond this
range, either all channels or only
channels whose alarm values have
exceeded the normal range are
recorded with real time informa-
tion. When leaving the alarm area,
storage is automatically interrupted
(Alarm Mode). This is a great
advantage for the
..documentation of breakdowns..
Besides that, a
... digital alarm output ...
is provided as a high and a low
active digital output channel and as
a relay output so that in case of
emergency e.g. machines are auto-
matically stopped or sirens are
turned on.

A scan is started by pressing a
pushbutton, at a defined date, by a
programming command or by a
digital signal.
It is finished either by another
programming command, by turn-
ing off the device or when the
storage capacity is reached (not in
Loop Mode).
Afterwards, the measuring data are
read out and sent to the PC for
processing.
Unlike the Continuous Mode, you
can also interrupt a scan in Alarm
Mode by turning off the device and
continuing afterwards.
As a device of the meM-series, the
meM-LOG-SE is provided with a
USB connection, which means
... high transmission rates
of the measuring data ...
from the data acquisition system to
the PC. In addition, the logger
features a serial connection
(RS232) so that the device can be
used together with all operating
systems supporting the serial inter-
face (even Linux!). That means
that also
... transmission by modem ...
is possible.
If not only voltages are measured
but other physical quantities with
sensors, the carrier board BP16
from BMC Messsysteme GmbH
supplied with the MAL miniature
measuring amplifiers is ideal for
the combination with the data
logger.
This is realized via a 1:1 connec-
tion of the 37-pole Sub-D sockets
at the front of the two devices.
Besides that, the BP16 can be
operated with the external power
supply provided at the Sub-D
socket of the logger.
The control of the meM-LOG-SE
takes place by programming via
the serial interface or by means of
the operating software ST-meM-
LOG SE included with delivery.
Since ST-meM-LOG SE supports
the same file format as the modern
software
... NextView®4 ...
for data acquisition and
processing, measuring files created
with ST-meM-LOG SE can be dis-
played in NextView®4 as graphic
signal curves and then be ana-
lyzed.
NextView®4 is also available as a
stripped-down "Analysis" version.
A free demo of the software is
included with delivery.
The instruction set for program-
ming the meM-LOG-SE is com-
patible to the ADAM4000 series.

1 Starting up the device and using the accumulator
Plug the two red frames onto the short sides of the device with the feet looking downwards as illustrated in the product
picture.
The power supply for the device (12V, 12W) is optionally available (ZU-PW10W) as accessory. In addition, an accu-
mulator is integrated so that (depending on the load) the meM-LOG-SE can be operated between 30 hours and 7
weeks without external power supply. As soon as the external power supply is connected (green LED on), the accumu-
lator is recharged. Charging is done within 3-4 hours approximately even during a scan. Before first use, charge the
accumulator for about 1 hour. To prevent any loss of data, do not deeply discharge the accumulator. In this case, it has
to be loaded with the device turned off. To keep the functioning of the accumulator, it should not stay unused for more
than one year.
For controlling meM-LOG-SE and transmitting measuring data, connect the device to the PC with a serial interface
cable (9-pole null modem cable) or USB cable (included with delivery) depending on the interface you want to use.
The logger is suitable for DIN rail mounting. The DIN rail set ZU-SCHI can be ordered optionally.
If using several measuring systems of the meM series or the amplifier system BP16, the red frames of the device can be
fit together, so that the devices form a stable unit (see chapter 5).

2 Functions of meM-LOG-SE
Various operation modes can be selected for the meM-LOG-SE concerning the scan frequency, the operation mode
and the storage mode. These are explained in the following table:
Funktion / Betriebsart Beschreibung
Normal Mode -sampling in steps of seconds in the range of [1s, .. , 65535s (=18h 12min 15s)]
-max. scan frequency: 1Hz per channel
-device switches into Sleep Mode (see below) between sampling data
Fast Mode -fine adjustment of sampling interval in steps of 1/100sec. in the range of
[0.01s, .. , 655.35s (=10min 55s 350ms)]
-max. scan frequency: 100Hz per channel (operating time of accumulator accordingly reduced)
-device does not switch into Sleep Mode (see below)
Continuous Mode -continuous storage of measuring data, next scan cannot be started before either measuring values
have been transmitted, scan configuration has been changed or memory has been deleted
-scan starting time is stored in UTC format (number of seconds since 1/1/1970)
-required memory space: 2 Bytes/value (max. 262144 values = 512*1024 Bytes : 2 Bytes/value)
Alarm Mode -storage starts as soon as the measuring values have reached or exceeded the limits of the set-up
normal range (analog) or level (digital)
-scan starting time and relative time referring to the start of the measurement is stored in UTC format
(number of seconds since 1/1/1970)
-required memory space: 7 Bytes/value
(max. 74898 values = 512*1024 Bytes : 7 Bytes/value)
-alarm values are set for each channel separately
-storage of either all channels to be saved or only of channels which are in state of alarm
-If measuring values are within their normal range again, the scan is temporarily interrupted. If not in
Loop Mode (see below) the scan continues until memory is full or measurement is stopped.
-even if a scan has been stopped with the device button it can be taken up again, the new measuring
data and time values are correctly added to the previous measurement
-in case of alarm the two digital outputs become active (Digital Out 1: 1Æ0; Digital Out 2: 0Æ1) and
the relay is switched (alarm outputs, see chapter 3.2)
Loop Mode -loop memory: if memory is full old measuring data are continuously overwritten, if reading out
sampled data during a scan, they are removed from the memory
-if Loop Mode is not selected, the scan is finished when reaching the memory capacity
Sleep Mode -energy-saving mode: turns off the external power supply, the serial and USB interface and the alarm
outputs
-changes into Sleep Mode 1 minute after turning on the meM-LOG-SE
-to "wake up" the device for 1min: shortly press (<0.5sec) the pushbutton at the front of the device
("Instant on", see chapter 4) or apply a "break"-signal at the serial interface (for at least 4sec)
-If the meM-LOG-SE has a connection to the operating software ST-meM-LOG SE it does not fall
into Sleep Mode.
-Shortly before scanning the next value meM-LOG-SE wakes up, writes it to the memory (Alarm
Mode: if in alarm) and falls asleep right away. The time before scanning can be set in steps of sec-
onds within the range of [0sec, .. , defined scan period]. Æonly in Normal Mode possible, the de-
vice does not sleep in Fast Mode!

3 Connections
The connections for the analog input channels and for the USB interface are located at the front of the device. All other
connections are accessible at the back of the device.
3.1 Analog connections
16 analog voltage inputs with ±5V measuring range (single-ended) are provided at the
37-pole Sub-D socket. The pin assignment of the 37-pole Sub-D female connector at
the meM-LOG-SE is listed in the table below:
Pin (Sub-D37) meM-LOG-SE
1..16 Analog In 1..16
17 VUSB (5V; 100mA)
18, 19 n. c.
20..35 Analog Ground (AGND)
36..37 Ground
The maximum potentials against ground must not exceed ±7V. Any channel overload may influence measure-
ments of other channels and may lead to wrong values.
3.2 Digital connections
Two digital input channels with CMOS level (low: 0V..1V; high: 3.0V..5V) are connectable at the meM-LOG-SE. The
connections are realized as a 15-pole Sub-D socket at the back of the device. Open digital inputs are always high. The
pin assignment of the 15-pole Sub-D socket is listed in the following table:
Pin (Sub-D15) meM-LOG-SE
1 Alarm Out H (active high)
9 Alarm Out L (active low)
8, 15 Relay contact (alarm)
3 Digital In 1 (active low)
11 Digital In 2 (active low)
12 Scan start (active low)
5, 13 Ground
2, 4, 6, 7, 10, 14 n.c.
In case of alarm, the alarm outputs and the relay contact at pin 1,9 or 8,15 become active at the same time as long as the
signal values exceed the defined range: Alarm Out H changes from low to high, Alarm Out L from high to low and the
relay is switched (Attention: The logger must not be in Sleep Mode!). That means, it is possible to connect a signal
transmitter to the logger. As soon as the measuring values leave the normal range, it is turned on indicating the state of
alarm by an acoustic or visual signal. It is also conceivable that in case of alarm a machine is turned off automatically.

Pin 12 features all functions of the device button (see chapter 4). That means if you connect pin 12 to ground, a scan
will be started. In this case, the pin must be short-circuited for more than 0.5sec and less than 4sec.
•The digital input and output channels are protected with 1kΩresistors. If the input voltage is not within the
admitted voltage range of 0V..5V, the device may be damaged.
•The signals of digital input channels are "hidden" among the analog measuring values, so that always at
least one analog input channel must be saved!
•To prevent any damages of the device, ensure that no voltages are connected to pin 12!
3.3 Connection to the PC
If connecting meM-LOG-SE to a PC, it can be controlled via programming and measuring data stored in the logger
memory can be read out. The connection is possible either via USB interface or via the serial interface RS232.
Interface Description
USB: -fast transmission of measuring data
-to be used with operating systems Windows®2000/XP/Vista
serial (RS232): -universal use on all operating systems supporting the serial interface, e. g. all Windows®operating sys-
tems, Linux and Mac OS
-transmission over great distances, connection of a modem
3.3.1 Serial connection (RS232)
The serial connection requires a 9-pole, cross-wired null modem cable, not electrically isolated, which is connected to
the two 9-pole Sub-D plugs of the logger and the PC (to be ordered under: ZUKA-SER9). The serial connection of the
logger is located at the back of the device. If your PC only provides a 25-pole serial connection, you need an adapter 9-
pole to 25-pole in addition. The pin assignment of the 9-pole Sub-D plug for the serial interface is listed in the table
below:
Pin (Sub-D9) meM-LOG-SE
2 RX
3 TX
5 GND (Ground)
•Programming of the meM-LOG-SE can only be done via the serial interface!
•Serial commands and data can only be sent between logger and PC if the transmission rates (baudrate) of
the RS232 interface and the meM-LOG-SE are the same.
3.3.2 USB
If using the USB interface, connect the included USB cable ZUKA-USB to the USB connections both at PC and meas-
uring system. The socket for the USB interface is located at the front of the logger.
3.4 Power supply connection
The device is supplied with power via the 3-pole DIN plug at the back of the
device. The input voltage must be in the range of 9..45V DC.
External power supply is also required if using the USB interface of the
PC! Optionally available as accessory is the power supply ZU-PW10W (12V,
12W).

4 Functions of the pushbutton and states of the LED
The pushbutton at the front of the device must be pressed to turn the meM-LOG-SE on or off. Besides that, the
pushbutton features various functions, depending on how long it is pressed and in which state and operating mode the
logger is.
The two LEDs give useful information about the current device status. As soon as the power supply is connected and
the meM-LOG-SE is provided externally with power, the green LED is on. In this case, the integrated accumulator is
charged at the same time. The red LED indicates different states, being on or off or flashing in varying speed or dura-
tion.
The following table helps to get an overview of the various functions of the pushbutton depending on the current device
status, of possible settings and the resulting state of the red LED:
Description of the function Press pushbutton for ... Device status before Status of red LED
•turn on device [1.5sec;4.5sec] off after 1.5sec LED on (flashing if
memory empty, shining if data
available)
•turn off device at least 5sec on fast flickering after 0.5sec, after
5sec LED off
•delete memory
(Æmeasuring data deleted, scan
settings are kept, device ready
for scan)

5 Using the BP16
If not only voltages are measured but also
other physical quantities like temperature,
acceleration, resistance etc. using sensors,
measuring amplifiers are necessary for signal
conditioning.
Especially comfortable is the connection of a
BP16 to the data logger, since the carrier
board for measuring amplifiers is mounted
into the same housing. If you fit the devices at
the red frames together, they form a stable
unit. The connection of a BP16 to the meM-
LOG-SE is directly possible via a 1:1 connec-
tion of the two 37-pole Sub-D female connec-
tors with a 37-pole ribbon cable.
The 5V auxiliary voltage, led out at pin 17 of the 37-pole Sub-D socket of the logger, supplies the BP16 with power
and turns it on and off.
6 Operating software ST-meM-LOG SE
With the configuration software ST-
meM-LOG SE, you can easily test the
functions of the logger via USB or
RS232 interface, configurate the device,
start scans or read out measuring data.
For further help, please have a look at
the respective user manual, which is
also included, or the integrated online
help. When developing the second
version, (SE: "Second Edition") great
emphasis was put on user-friendliness
and reliability.
¾Administration of USB and the serial interface in one program
The connection between PC and data logger is realized via the serial (RS232) as well as the USB interface so that
the advantages of both interfaces are available to the user (see chapter 3.3). ST-meM-LOG SE manages both inter-
faces so that one device (or several) can be connected to USB and another to the serial interface at the same time.
¾Connection of several devices
Using the USB interface, up to 127 devices can be operated with ST-meM-LOG SE. To connect more than one log-
ger, the serial interface RS485 must be used. This requires a converter between RS232 and RS485. In this case 255
devices at the most can be used.
¾Live display
Incoming live data of the analog and digital inputs of the selected device are continuously displayed as numerical
values or digital levels (0 = low, 1 = high). The 16 analog channels are presented as physical quantities within their
adjusted measuring range with physical unit and channel name.

!Analog input values are displayed as physical quantities if adjusted and not as simple voltages. Saved measur-
ing values are shown in the live display during a scan in Continuous Mode or in Alarm Mode (saving all chan-
nels in alarm). Channel values that are not scanned are removed from the display. Alarm states are signalized
by a red marking.

¾Continuous Mode, Alarm Modus, Loop Mode ... – and even more
ST-meM-LOG SE supports or even extends all functions integrated in the data logger (see chapter 2). For example
in Alarm Mode, you can either save all selected channels or only the ones that exceeded the normal range.

!Reading out measuring data during a running scan is now possible in all operating modes.
¾Store measuring data with different file format
When reading out measuring data from the memory of the data logger, ST-meM-LOG SE writes files in *.txt or
*.lfx file format, which can be displayed as table values and analyzed in various programs for word processing
(Notepad®, Wordpad®, Word®etc.) and spreadsheet (e.g. Excel®). Especially to mention is the storage as an *.lfx
file, the file format of the professional measuring software NextView®4 (free demo version on the "Software Col-
lection"-CD or at Uwww.bmcm.deU). Here signals runs are graphically displayed and can be processed by means of
extensive analysis functions.

7.1 Driver installation
If connected to USB, a driver installation is required for meM-LOG-SE in contrast to a serial RS232 con-
nection. Only then additional software can be installed. To make sure that the installation is done correctly,
please follow the instructions in the order as described below.
7.1.1 Install driver package
The prior installation of the bmcm driver package UBMCM-DRUto the hard disc of your PC makes the driver search for
Windows®much easier. Especially in case of driver updates, only the new driver package has to be installed, the hard-
ware automatically uses the new version. The link to install the driver package is located on the meM-LOG-SE prod-
uct page of the "Software Collection"-CD.
7.1.2 Plug&Play installation
As soon as the meM-LOG-SE is connected to the PC, the system announces the new hardware. Start the automatic
hardware detection by selecting the following option:
-Windows®XP: "Install the software automatically" (SP2: do not connect with Windows®Update!)
-Windows®2000: "Search for a suitable driver for my device"
Under Windows®Vista, no selections have to be made. The driver is found and installed automatically upon connection
of the hardware, because the driver package has been installed on hard disc before. For the same reason, no additional
location needs to be entered for the driver search under Windows®2000.
7.1.3 Check installation
In the Windows®Device Manager, the entry "Data Acquisition (BMC Messsysteme GmbH)" is included after success-
ful installation displaying the installed bmcm hardware. To open the Device Manager, proceed as follows:
-Windows®Vista: Start / Control Panel/ System / "Device Manager"
-Windows®XP: Start / Control Panel / System / TAB "Hardware" / button "Device Manager"
-Windows®2000: Start / Settings / Control Panel / System / TAB "Hardware" / button "Device Manager"
Double click the meM-LOG-SE to open its properties. For general information, any existing device conflicts and pos-
sible sources of error see TAB "General".
7.2 Installation of ST-meM-LOG SE and NextView®4
Install the operating program "ST-meM-LOG SE" for configuring and operating the data logger. The setup program is available on the product page of the meM-LOG-SE. The device can be connected both via USB
or via the serial interface (RS232).
Install the demo version of the professional software NextView®4 for measurement data acquisition and
processing to graphically display and analyze the signal files created with ST-meM-LOG SE. The setup
program UNV4-DEMOUis available in the section "NextView®4.x".

8 Important notes for using meM-LOG-SE
•The device is only suitable for extra-low voltages – please observe the relevant regulations! For reasons relating to
EMC, the device must only be operated with housing closed. ESD voltages at open lines may cause malfunction
during operation. Only use an electrically isolated power supply unit (with CE).
•For cleaning the device use water and mild detergent only. The device is designed to be maintenance-free.
•At the 37- and 15-pole Sub-D socket signal cables are connected – use shielded cables only. For best possible inter-
ference suppression connect shield at one end only. Close open inputs if necessary.
•The device ground and the chassis are electrically connected to the chassis of the PC, which is usually also con-
nected to ground. Be sure to avoid ground loops, since they will cause measuring errors!
•PCs (notebooks), which are not grounded often produce high potentials to earth at the USB socket, so that safe
operation cannot be guaranteed. In this case connect the data logger to earth.
•The Gain is adjusted to even values. Therefore only 4000 (with 12 Bit) values of the full range of the converter are
used. As a result, the measuring ranges are slightly larger (±5.12V) than the indicated measuring ranges, so that
overranges can be recognized. The AD converter of meM-LOG-SE has a code noise of up to ±1 LSB.
•If the device has not been used for longer (>3 months), the integrated accumulator must be recharged .
•The device must not be used for safety-relevant tasks. With the use of the product the customer becomes manufac-
turer by law and is therefore completely 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.
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.

Sampling rate: 1.5*10-5Hz .. 1Hz / channel 1.5*10-3Hz .. 100Hz / channel
Sampling period: 18h 12min 15sec .. 1sec (in steps of sec.) 10min 55sec 350msec .. 0.01sec (in steps of 1/100 sec.)
Total sampling rate*: 16Hz 1.6kHz
* The total sampling rate is the sum of the sampling rates of the individual used channels (e.g. 5 channels à 100Hz => 500Hz total sam-
pling rate). The values for accuracy always relate to the respective measuring range. Errors might add at worst.
