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.
