Hardware-Revision 4.0 with M12 connectors
FPGA Firmware-Revision 4.6
Controller Firmware Revision 2.0.59
This manual describes the installation of the scanner hardware and the use of MEL demo and calibration
software. The manual has been changed to the new version of hardware.
With the transit to the revision 4 hardware, the electronic system has been equipped with M12 connectors.
The scanner head is connected to the network with the standard Ethernet M12 connector. The power and
control connector is an M12 connector with 8 pins.
 Tipp: default values should be read from the scanner.
after a reset, the scanner restores all values to default.
to read out the default values:
1. send reset command 0x1E
2. request info telegram 0x21
default values could be different from given values in this manual.
relevant is the actual interface description available from MEL.
when you read out default values from the scanner, these may be
the almost recent values.
 Laser Safety
Please refer to the Chapter “Laser Safety and Maintenance” to find recommendations and guidelines for
use of controls, adjustments of performance and recommended practice to avoid any hazardous radiation
exposure (page 43). Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.

With the new M2-iLAN „Ethernet“-Scanner the electronic system is integrated in the scanner head. The
system has no extra controller box, so it is highly compact, tight and rugged. The scanner head has two
M12 connectors for Ethernet and power supply & controls. Scanner heads designed for welding applications
additionally have water & air cooling fittings.
M2W-iL-models are rated up to 500°C (950° F) environment
temperature with water cooling, up to 150°C (240°F) with air cooling,
dry and clean atmosphere, non corrosive.

The scanner head has a CCD camera, a line laser projector and an electronic system for digitizing the
camera signals. The electronic system sends the camera signal to the electronic system. The camera is
controlled by the automatic control through the electronic system or in external mode by the application
software. Adjustment for shutter time, video gain and laser intensity are made through either automatic or
under “manual” control by the application software.

Standard Ethernet components never have shown problems in the data transmission of the Ethernet
scanners. Network connection Rx+, Rx-, Tx+, Tx- is available on a 4-pin M12-connector D-coded according
to standards. The scanner should be connected with shielded Ethernet cables CAT 5e or better. Total cable
length for Ethernet cabling is 200m according to Standard IEE 802.3
We also use Ethernet scanners in the company network without any effect on the daily office work running
through the same network. Use Ethernet switches, hubs are not recommended. When several scanners are
monitored by one PC, the graphic card and CPU must be strong enough to collect all the data provided by
the scanners. When you doubt, that the Scanner does not deliver all images, you should check the image
counter (page 15: register 0x11, status messages.) The image counter number allows sorting images, if
they arrive in wrong order. This may happen accidentally when transmitting profile data over the internet.

The Ethernet network connection is
made with M12 connectors, 4 pin D
coded. The control interface is
connected through an 8 pin M12
connector, the pin details are given
on page 6.
Ethernet cables should be double
shielded. The cables should be
according specification CAT 5e or
better.
When the Scanner is connected to
the network over a Ethernet switch,
normal (1:1 wired) patch cable may
be used. When you want to make a
direct connection from the Scanner
to the PC use a cross-wired cable.

Up to 32 Scanners could be integrated in a network. Normally, you should use a separate network card for
the connections to the scanner(s). The use of a separate network card is optional and depends from your
network settings, network traffic on the dedicated PC and system load. You may use a Ethernet switch, a
Ethernet cable to each scanner and power supply 10 … 28 V DC.

 The Scanner sends 290 Profile points per Scan with 93.5 Hz :
oTCP-IP Header
oM2DF-LAN-Header
oProfile data
oStatus information
oReserved Bytes for additional data
oadditional Information as Encoder-Data, FiFO
oCRC
Each Profile creates a 2048 Byte Block = 93.4 x 2.048 kBytes / s = 191.28 kByte / s.
The network channel has 100 Mbit = 12.500 kBytes / sec
This will allow theoretically maximum = 12.500 / 191 = 65.4 Scanners.
The numbers of collisions in a network rises, when the network load exceeds 50%. Therefore as a realistic
figure, we assume 50 % of maximum transmission rate.
This leads to the number of 32 Scanners for maximum usage in one network segment.
Segmentation of data blocks
Limitations of the network cards like setting of the MTU (Maximum Transfer Unit), and accordingly load in
the network causes that the 2048 Bytes will not be transferred in one packet, but segmented into two
packets of 1460 k and 588 k. The user must not think about this effect, though the TCP implementation of
the operating systems cares about sorting and reconciling the TCP packets. More likely, the software
engineer designing an application must know this and wait long enough to make sure that all packets have
been received, before using the data.

 At the end of the manufacturing test the scanners are set to:
IP address 192.168.123.245
Subnet mask 255.255.255.0.
Before you integrate these units in your network, you should set the network address to a working address
which will operate in your network properly. For more technical details and background information see the
network tutorial. The set up procedure is given on page 24.

* when connecting the sync output to the command input 1, at start of the sensor (power on), the sensor is brought to
the programming mode. In this programming mode the firmware can be uploaded with the RS-232 connection or over
the Ethernet network.
** when the sync output is connected to the command input 2, at start of the sensor, the sensor will activate the RiP
mode and communicate only at the default IP address.
Please note: when both command inputs were connected to sync out, the sensor will go to the programming mode.
The activation of the Programming mode or RiP mode is made only when the sensor is switched on and had no
power before for a few 10 seconds.
*** colors are given as an example.
Tipp: the Scanner could be connected with one single*, highly flexible, cable for robotic applications. The cable used
is a Ethernet cable specially made for the use with robots. The power supply is taken over two unused wires in the
network cable, following the idea of the IEEE 802.3af standard. Details are given in the TE-M2-iLAN-connection-E.pdf.
Cables following this definition are available from MEL on request.

TCP Clients and Server are components of the development environment in the software. In the readily
compiled software (*.exe File) these components exist in the form of “ports”. These ports manage data
traffic in and out to the individual elements of the application software.
The Scanner communicates with the outer world using port address, IP address and a valid subnet mask.
A Gateway is ignored, the scanner opens a peer to peer connection. Therefore the set up of these
communication components needs to be complete to allow proper function of the electronic components
and data communication.
The Scanner stores data in FiFo memory, before data is sent out in a package. The transmission protocol is
TCP/IP*.
* UDP firmware version is available on request!

The Scanners electronic system has a default address as well as a working IP address. The default IP
address is activated, when you set the RiP-Pin. This is done, when you connect the Sync out pin to the D1
pin before starting power. The default IP address is set firmly, and can not be changed by the user.
Before delivery, the scanners were normally set to the working-IP = 192.168.123.245. When another IP
address has been set, either a note in the shipment papers or a label on the electronic box of the scanner
should show the IP address.
When you want to set a new working IP address, use a Web browser and follow the procedure on page 24.
 Please note: after transferring the new working IP address to the scanner electronic system, the
electronic system automatically restarts to make the change effective.
The Web Browser will then display a message to make you aware of the change.
When you receive this message connect to the scanner with the new IP address.

Using the default IP address is meant for communication with one single scanner, for adjustment of a new
working IP address or other service purpose. Using the default IP address for normal operation is not
recommended.
DHCP is not supported. The Scanner must have a fixed IP address, as well as the network card to which
the scanner shall communicate. Scanner and network card must be in the same network segment. This
means, the network address should vary only in the last three digits. Computers in the network must use
unique and different network addresses. When units in the network use the same address, a conflict exists.
The communication in the network could severely have problems, when this happens.
 Tipp: label the units when installing different units in a network
take notes and make a plan of the network addresses used in your network.
when a conflict exists, physically disconnect the network cable form different units to find
out the source of conflict. ... only one unit at a time...

Address Scanner 1: 192.168.123.222;

The subnet mask for all Scanners and the network card = 255.255.255.0
Do not get mixed: a subnet mask 255.255.0.0 may also work. The subnet mask defines the maximum
number of units in your network. When no more than 254 scanners were present in your network, the
subnet mask 255.255.255.0 will be sufficient.
In our example Scanner 7 has been set erroneously to the IP address 192.169.123.224. this address is
already taken from another Scanner – so a conflict exists. The correct IP-address would have been
192.168.123.228.
Scanner 9 is in another subnet (another network segment). For Scanner 9, the network card should be set
to IP address = 192.168.124.10.
 Tipp: how to find out the IP address of the scanner?
1. Use any terminal software, connect the RS-232 diagnostic port to Com-port 1 of your PC
2. Read out the information prompt send out at start up of the scanner.
3. For details see page 22.

 Back ground: the Scanner and the network card in the PC make a “peer to peer” connection. Once the
communication between these two peers has been initiated, no other network device will be allowed to communicate
with the active scanner. This means, the scanner can communicate only with one PC at a time. Besides the
communication over TCP at any time, from any other PC a http request (Web browser) could be made.

After the Start of the Scanner (switch on power), the configuration of the scanner is loaded from the internal
EPROM to the micro controllers memory. The MEL demo software then shows the following information:
oTCP/IP Address, Port and MAC Address
oIntensity, shutter time, Video gain
oScanner Status, Firmware-Version, Scanner head temperature
The main window of Ethernet-Demo-Software has the elements profile display and tabs for different function
groups. The profile display at the left side can be switched to display one bigger screen or four small
screens simultaneously. The colors of the profiles can be adjusted by defining RGB values in the settings.ini
file. Function groups are selected with the Tabs 1 … 16. The important Tabs are discussed in the following
text. The Tab 1 defines the IP address and assignment of the display window. The window count of the four
windows starts at 0 and counts up to 3. The big window is number 9.

The function slider “Pixelauslesen begin” and “Pixelauslesen end” allows to crop the scanners viewing area.
This feature is helpful for scanning extremely difficult targets. It improves scan profiles by cutting off
unwanted reflections. Depending on the setting of the demarcation limits, the internal profile acquisition
algorithm will ignore reflections below or above the levels of demarcation, which could greatly enhance the
online scan profile in extreme situations. The effect can be monitored directly on screen.
 Tipp: mathematical post processing of the profile will not be able to produce a similar effect.
The effect of erasing reflections and unwanted profile noise is due to removing these data
before creating the profile.
This is a function of the FPGA processing inside the scanner head.

No commands must be sent to the scanner, unless special operation is required. When no special
command is sent, the scanner is in automatic mode, which is best for most applications.
When the scanner is powered on, it sends data to the connected PC in a continuous stream. You must not
care to set the scanner to this operation mode, this will be made automatic, presumed once the application
software has been configured correctly. Windows TCP socket cares, that all packets will arrive at the PC, no
user interaction is required.
When creating a new communication with the scanner after a long waiting period, we recommend to send a
FiFO reset command just once in the beginning. This is only relevant for your own application software, to
avoid reading out old data from the FiFO memory at start. When using this command, you should trash the
first image after the reset and use only the second one. When reading data continuously, FiFo reset is not
recommended.
 Tipp: examples for the use of register addresses and commands were given in the appendix.

At Pin 6 = Sync-in, the leading edge of the trigger pulse makes the trigger event. The signal should not
oscillate. The Sync-input is an optic coupler with current limit. The voltage range is TTL … 24 V (max. 30 V
DC). When the trigger has been made, no additional trigger signal will be accepted during the active
measurement. The maximum profile rate is approximately 60 Hz.
 Tipp: how to use trigger:
1. set register 0x14, Bit 3 to “1”
2. do trigger with a call of register 0x1D,see page 15
 Please note: in trigger mode, synchronization with other scanners is not available.

The sync-input is used for synchronization of 1 master with other slave scanners. One scanner is defined to
be the master; the other scanners will be slaves. The sync output of the master scanner is wired to the
slave scanners sync input, ground is connected accordingly.

The command 0x21 reads out the status information in one complete packet from the scanner. When you
have sent the command 0x21 to the scanner and watch out for a packet with the protocol version 0x10. This
protocol revision number is in the byte 60 of the header. When you found 0x10 in Byte 60, you have
identified the info telegram packet. Protocol version 0x11 is the message that something with profile scan
data status is wrong.
At the end of the packet, additionally 31 bytes of function register status is sent, then the FiFO fill status
information. The table on the next page shows the details.
When the command 0x21 is received by the scanner, a packet with 2048 Bytes is sent from the scanner to
the PC. The packet contains all information of the registers 0 … 63, but no scan profile data. From Byte 130
on, the firmware version is sent as a string. The end of the string is 0x00.

* each access to the register triggers the function. It is not required, and it makes no sense to write any value to the
register. Simply calling the register address makes the necessary function work.
The register 0x11 selects the content of the status register. The status register has the parameters temperature of
sensor head, register contents, version of electronic system and camera, operating hours counter, on counter, digital

valid for Ethernet Scanners, ISA board and i-Control.
Special register 0x18 (24)
The special register 0x18 allows to query sensor data direct. When a value smaller than 127 is written to the register,
the read out of the FiFO is stopped and the register is put to the data bus. The number of the register is the content of
the special register. Data will remain on the bus as long as the special register is written again with 127. Then normal
image transfer is possible again.

Reg. value Bit Nr. Meaning

7 ... 0 Bit 7 ... 0 of the register 13 represent the Bits 9 ... 2 of the laser control value in automatic mode. The lower bits were not sent back by the sensor, these can
not be read back. For adjustment, the bits 2 … 9 are sufficient for set up. For
set up the sensor firmly to a special value, we recommend the following
procedure:
1. set the Scanner in automatic mode on the target surface
2. read out Bit 2 ... 9 from status register
3. set Scanner in manual controlled (external) mode
4. write back the previously read out values
Bits 0 and 1 are set to „0“

Register 14 shows the 3rd digit of the version number.
Example : revision = 3.6.2
Status Register 2 = 36 // Version x 10 = 3.6; Integer
Status Register 14 = 2 // natural number = 1, 2, 3 … Integer
