LAN-AD16f
LAN data acquisition system (TCP/IP)
Data acquisition via network.
Remote. Ingenious.
The LAN technology of the LAN-AD16f allows
for measurement applications across great dis-
tances. The number of measuring points, where
the devices are installed, is basically not limited.
Data transmission to a server PC is fast and reli-
able.
TCP/IP. Guaranteed reliable.
The LAN-AD16f uses the TCP/IP protocol pro-
viding for safe and complete data transmission.
Besides that, transmission via internet is possible
- data acquisition with absolutely new possibili-
ties.
16 analog inputs. 250kHz.
16 Bit. ±10V, ±5V, ±2V, ±1V.
16 analog inputs can be sampled precisely with
16 bit resolution and 250kHz total sampling rate.
The measuring range is selected via software for
each channel separately.
2 analog outputs. 16 bit. ±10V.
The two 10V outputs can be used for analog con-
trols with 16 bit accuracy.
4 digital inputs/outputs each.
1 counter.
Digital states are recorded or set at 16 digital in-
puts and outputs each. Digital inputs are sampled
time-synchronously with the analog inputs. One
19-bit counter accessible via the first digital input
pins allows the acquisition of counting pulses or
the connection of an incremental encoder.
Cascadable. Synchronizable.
The number of DAQ systems and with it the
number of available channels is only limited by
the bandwidth of the network. Several LAN-
AD16f devices can be synchronized with each
other. If so, all measured data in distributed op-
eration always keep time even with long-term
measurements.
Open for everyone.
Widely supported: The data acquisition system
can be used under Windows®7/XP as well as un-
der Mac OS X, Free BSD and Linux. The com-
plete software for installation and programming
of the LAN-AD16f is included for free.

LAN-AD16f
1Start-up procedure
Plug the red frames onto the short sides of the device with the feet looking downward. The LAN-AD16f is
suitable for DIN rail mounting. The optional DIN rail set ZU-SCHI can be ordered at bmcm.
The device is supplied via a power supply unit (12V, 10W) available under ZU-PW10W (see chapter 2.1).
Connect the device to a PC or server via network (see chapter 2.2). The LAN-AD16f self-assigns a suitable
link-local address when being connected.
If necessary, further software components to be used with the device can be installed now, as described in
chapter 4.
2Connections and pin assignment
Figure 1
2.1 Power supply
The power supply of the DAQ system with 9-40V DC is connected at the 3-pin
DIN plug on the back of the device. The power supply unit ZU-PW10W (12V,
12W) is optionally available.
2.2 Network
The PC/data acquisition server and the LAN-AD16f communicate via network, which is real-
ized with by a Twisted Pair connection (100Mbit). If directly connecting the LAN-AD16f to
the PC, a crosslink cable must be used. Both cables are available as accessories (ZUKA10T or
ZUKA-CL10T).
If the two LEDs in the LAN connector are flashing, data are transmitted.
Firewall software installed on the PC might interfere with the operation of the LAN-AD16f. In this
case, please contact your network administrator.

LAN-AD16f
2.3 Analog channels
The 37-pin D-Sub female connector at the back of the device is
designed for the connection of the analog inputs and outputs. Input
range (±10V, ±5V, ±2V, ±1V) and output range (±10V) are set via
software (e.g. in NextView®4).
The pin assignment of the 37-pin D-Sub female is as follows:
D-Sub 37 LAN-AD16f D-Sub 37 LAN-AD16f
1 AIn 1 11 AIn 11
2 AIn 2 12 AIn 12
3 AIn 3 13 AIn 13
4 AIn 4 14 AIn 14

7 AIn 7 17 n. c.
8 AIn 8 18 AOut 1
9 AIn 9 19 AOut 2
10 AIn 10 20..37 AGND
The max. potentials to ground must not exceed ±12V. Any channel overload may influence measure-
ments of other channels and may lead to wrong values.
The internal connection of the 16 analog inputs is provided via
a 40-way pin connector (see figure on the right) on the
LAN-AD16f board, which, for example, can be used to con-
nect current shunts (ZU-CS250R available as accessory).
The pin assignment of the 40-way pin connector is listed in the
following table:

2.4 Digital channels and counter
The LAN-AD16f features 16 digital inputs and outputs each (low: 0V..0.7V; high: 3.0V..5V). The digital
lines are hard-wired. A 19-bit counter (quadrature decoder) is additionally integrated allowing the connection
of an incremental encoder. The counter or incremental encoder and the external counter reset, if required, are
attached to the first digital input lines.
All lines are led to the 37-pin D-Sub female connector at the device front. The pin assignment is as follows:
Pin LAN-AD16f Pin LAN-AD16f Counter
1 DOut 1 11 DIn 1 Signal A
20 DOut 2 30 DIn 2 Signal B
2 DOut 3 12 DIn 3 Reset

27 DOut 16 37 DIn 16
9, 28 5V, max. 50mA 10, 19, 29 DGND
The digital inputs and outputs are protected by serial resistors. Input voltages beyond the permitted
voltage range of 0V..5V can damage the device.
The counter of the LAN-AD16f counts the num-
ber of incoming pulses (max. 8MHz) sampled at
the connection of signal A. If the maximum
counting range is reached, the counter will be re-
set 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 de-
coder considers the counting direction by decoding a second phase-shifted signal.
To activate the counting function, the respective digital lines of the LAN-AD16f must be programmed to
counter operation via software.
Function Description Max. pulse frequ. Connection Dig. pins used Counting range
Counter count Ç8MHz Signal A 1 0..219-1
Up/Down counter count ÇÈ 8MHz Signal A, Signal B 2 218 .. 218-1
Incremental encoder count ÇÈ 2MHz Signal A, Signal B 2 218 .. 218-1
Please see the manufacturer's documentation for details about connecting your incremental encoder.

3Interfacing examples for digital channels
The following basic connection examples demonstrate the use of the digital inputs and outputs and the con-
nection of a counter to the LAN-AD16f. The pin assignment of the 37-pin D-Sub female connector is de-
scribed in chapter 2.4.
3.1 Connecting an optocoupler
Optocouplers provide optimum protection at
each input line. With them, it is possible to
connect higher voltages and to protect the
hardware from being destroyed.
The 3.9kΩpull-down resistor sets the input
to low if no voltage is applied there.
In this regard, please also see application ex-
amples of the optocoupler you use.
Optocoupler boards with 8 or 16 inputs
are available at bmcm.
3.2 Connecting a counter or
incremental encoder
The connection of "Signal A", "Signal B"
and "Reset" is possible at any digital line.
At maximum performance (219-1), the
counter is reset and starts from zero again.
3.3 Connecting an LED
Only so-called low-current LEDs can be
used, because they already work with 1mA
current.
Serial resistors in the output lines limit the
current and protect the hardware from being
destroyed.
Please also observe the total current listed
in the technical data (see chapter 8).

4.1.3 Notes about TCP/IP
Each participant of the network has his own IP address consisting of four groups of numbers. To guarantee
that a data package arrives at the correct address, this IP address must have been given out only once.
Each IP address contains the network number identifying the net your PC belongs to. Please make sure the
PC and the LAN-AD16f are in the same net, i.e. they have the same network number, to be able to commu-
nicate with each other.
4.1.4 Example configuration for the manual input of the network settings

7Important notes for using the LAN-AD16f
•The device is only suitable for extra-low voltages - please observe the relevant regulations! For reasons relating to
EMC, it must only be used in closed PC housings. ESD voltages at open lines may cause malfunction. Only use an
electrical isolated power supply unit (with CE).
•Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free.
•Signal cables are connected at the two 37-pin D-Sub female connectors – preferably use shielded cables. For best
possible interference suppression, connect shield at one end only. Close open inputs if necessary.
•The gain is adjusted to even values. Therefore, only 64000 values (for 16 bit) of the full range of the converter are
used. As a result, the measuring ranges are slightly larger (e.g. ±10.24V) than the indicated measuring ranges so
that overranges can be recognized.
•The device must not be used for safety-relevant tasks. With the use of the product, the customer becomes manu-
facturer 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 dis-
posed according to the WEEE directive or can be returned to bmcm at your own expense.
