AMS42-LAN16fx
5B Amplified Measurement System (LAN)
All-In-One Measurement System.
Compact. DAQ via LAN.
The AMS42-LAN16fx, a complete solution: ampli-
fier technology and data acquisition. A high-quality
network data acquisition system is already inte-
grated. Available in a robust aluminum housing as
a mobile tabletop unit with skid-proof, tip-up feet.
Modular Concept.
Equip Individually. Be Flexible.
The AMS device is equipped with cassettes, on
which the required 5B measuring amplifiers are
mounted. The variety of available 5B modules al-
lows for the optimum adaptation of the
AMS42-LAN16fx to any special measuring task.
Choose Connector.
Mount 5B Amplifier. Done.
The available plug-in cassettes have different con-
nectors at the front panel. The suitable cassette
can be chosen depending on the sensor or signal
to be connected. Now the 5B module only has to
be fixed on the cassette and be integrated in the
AMS system.
Clearly Safe.
The galvanic isolation provided by the 5B modules
allows interference-free operation and protects
DAQ system and PC against high potentials.
16 Analog IN. 2 Analog OUT.
Signals are connected at 8 amplifier inputs with 16
bit resolution and 250kHz total sampling rate. Ad-
ditional 8 analog inputs and 2 analog outputs are
available directly and without amplification at a D-
Sub 37 female.
32 Digital I/O. 3 Counters.
Digital states are recorded or set at 16 digital in-
puts and outputs each. The direction of the two
16-bit ports is set via software. Pulses, frequency,
position, and pulse time can be measured with
three 32-bit counters.
Networked. Distributed. Remote.
Synchronized, if you Like.
The LAN technology of the AMS42-LAN16fx allows
for measurement applications across great dis-
tances. Data are transmitted via network from arbi-
trarily many measuring points to a server PC. Sig-
nals of several devices can be synchronized with
each other. The TCP/IP protocol stands for reliable
data transmission – even via the internet.
Open for Everyone.
The amplifier measurement system is supported by
Windows®XP/7/8/10 as well as Mac OS X, Free
BSD, and Linux. The complete software for installa-
tion and programming of the AMS42-LAN16fx is
included. The device is supported by the DAQ and
analysis software NextView®.

3.5 Analog Channels
3.5.1 Measuring Amplifier Inputs
Eight analog signals can be connected to the amplifier inputs available at the respective connectors of
the cassette panels. Their assignment is illustrated in the data sheet of the AMS-K cassettes (see
chapter 6.2).
Additional 8 amplifiers inputs can be added with the option AMS-EXT8 (see chapter 6.4) at the back
of the device.
Depending on the application, the shield of the analog input cables can be applied to ground or 0V.
Be sure to connect at one end of the cable only. Run the signal ground separately if possible. Lay in-
put cable separately if possible.
Measurements can be effected on various potentials. The potential deviations, however, should not exceed 60V DC (ac-
cording to VDE Association of German Electrical Engineers).
3.5.2 Analog Outputs and Other Analog Inputs
The 37-pin D-Sub female connector at the back of the device
is designed for the direct and non-amplified connection of the
remaining analog inputs 9..16 and the analog outputs 1+2.
The input range (±10V, ±5V, ±2V, ±1V) is set via software (e.g.
in
NextView®
), the output range is ±10V, the resolution is 16
bit respectively.
The max. potentials to ground must not exceed
±
12V. Any channel overload may influence measurements of other chan-
nels and may lead to wrong values.

•The digital inputs and outputs are protected by serial resistors. Input voltages beyond the permitted voltage range of
0V..5V can damage the device.
•By default, port A is set to input, port B to output.
•Digital inputs are always read synchronously in time together with the analog inputs.
•Make sure the digital outputs of the device do not drive against the outputs of your signals.
3.6.2 5V Auxiliary Voltage
The AMS42-LAN16fx provides an auxiliary voltage (e.g. for sensor supply) at pin 9, 28 of the D-Sub37
female. The 5V DC output (max. 10mA) is protected by a fuse (multifuse). In case of overload, it is suf-
ficient to interrupt the power supply (turn off PC or disconnect the consumer load). After app. 1 min.,
the multifuse will be regenerated.

3.6.3 Counters with Pulse Time Measurement
The AMS42-LAN16fx features three 32-bit counters allowing the connection of incremental encoders.
The counter inputs (A, B, and Reset) can be assigned to any digital lines of the two digital ports (confi-
gure by software).
The AMS42-LAN16fx counts the number of incoming pulses (max. 16MHz) sampled at the connec-
tion of signal A. If the maximum counting range is reached, the counter will be reset to the minimum
value of the counting range. If the external counter reset is connected, the counter can be reset at any
time.
In comparison to a counter, the quadrature decoder used to connect an incremental encoder consi-
ders the counting direction by decoding a second phase-shifted signal.
To activate the counting function, the respective digital lines of the AMS42-LAN16fx must be assigned
to the counter via software.

4 AMS Backplane
The AMS-backplane provides 8 slots for 5B modules and the AMS-K plug-in cassettes (see chapter
6.2) carrying the 5B modules. If the AMS42-LAN16fx is used with the optional add-on AMS-EXT8 (see
chapter 6.4), eight slots each are available at the front and at the back of the device.
4.1 Ground-to-Ground Resistance
Ideally, the output ground is not electrically connected with the power supply ground. If, however, a
connection to ground is necessary (e.g. to use the output switch in the 5B module), the 2-pin jumper
(see fig. above) must be closed.
In the case of electrically connected systems (e.g. PC), this jumper represents a high-resistance bridge (1k
W
) and may
generate a hum loop!
4.2 Module Pin Assignment
The pin assignment on the right shows the top view of the module
backplane (see chapter 4).
The pin assignment corresponds to the 5B modules of Analog De-
vices®, BURR BROWN®etc. However, an additional 0EX pin has
been introduced, which is particularly suitable for ungrounded shiel-
ding. This is a specific assignment of BMC Messsysteme GmbH.
This pin is not connected in modules of other manufacturers.
4.3 Fuse
The fusing of the AMS backplane (see chapter 4) is effected on the backplane with one reversible
semi-conductor fuse. In case of overload it turns off. To make the fuse work effectively again, first re-
move the cause for overload before disconnecting the power supply of the AMS42-LAN16fx.
4.4 Connection for AMS Cassettes
The cassettes are connected to the AMS backplane (see chapter 4) via 7-way pin
connectors leading the input signals connected at the cassette panel to the backplane.
The assignment of the 7-way female connector on the board is illustrated in the figure
on the right-hand side.

7Important Notes for Using the AMS42-LAN16fx
•The device is only suitable for extra-low voltages - please observe the relevant regulations! Only
use the device with housing closed. ESD voltages at open lines may cause malfunction.
•Only use an electrical isolated power supply unit (with CE).
•For cleaning only use non-solvent detergents. The product is designed to be maintenance-free.
•For calibration purposes, the device must be returned to BMC Messsysteme GmbH.
•For reasons relating to CE use shielded cables. Connect the shield to ground at one end only.
Close open inputs if possible. ESD voltages on lines may cause malfunction during operation.
•When mounting the cassettes, a connection between power supply ground and chassis of the
device is made via the module screw.
•The Gain is adjusted to even values. Therefore only 64000 (with 16 bit) values of the full range of
the converter are used. As a result, the measuring ranges are effectively slightly larger (e.g. ±5.12V)
than the indicated measuring ranges, providing for the advantage that overranges can be recog-
nized.
•The device must not be used for safety-relevant tasks. With the use of the product, the customer
becomes manufacturer by law and is therefore fully 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.
