M7LL and M70LL sensors provide data output over Ethernet. Transmission of many sensors over one network cable is simple and will
not create problems. The TCP protocol does not require any specific hardware functions, standard IT hardware and CAT ‐ 5e network
cables will allow the use of M7LL and M70LL sensors.
For very weak network systems the sensor could be set to 10 Mbit data rate (standard = 100 Mbit). Gigabit hardware is not required,
but will operate without problems.
Monitoring a bunch of sensors with one single PC will require some performance, therefore the PC and graphic card should have
enough resources to operate the required software.

Ethernet signals are available on a DSub ‐ 25 pin connector which is also the connector for +24 V power supply.
The sensor should be connected with shielded Ethernet cables (CAT ‐ 5e or better) to the network. For long cable runs of up to 200 m
we recommend using 10 Mbit transmission speed and shielded cables.
When the sensor electronic system is connected to an Ethernet switch, a standard patch cable (wired 1:1) could be used. When the
electronic system should be connected directly to a network card in a PC, TX ‐ and Rx ‐ wires should be re ‐ routed by a crosslink cable.
Both types of cable are available in electronic markets.

Theoretically up to 90 sensors can be used in one single 100 Mbit network. We recommend using an additional network card in the
PC for the sensor network*, a power supply (10 ... 30 V DC) for the sensors and a bunch of Ethernet cables.
* for the sensors you should use an own network card, this helps to avoid that network activities in the PC would affect the sensor
network and vice versa. In this case the sensors are in a separate Subnet. This helps to keep the sensor network separated from the
other networks in your company.

IP default address = 192.168.122.245 *
Port = 3000 *
Subnet mask = 255.255.255.0.*
* on request before delivery: custom IP ‐ Addresses were set according to custom specifications.
When S ‐ output and S ‐ input are connected before power on, the sensor is reset to factory default IP address.


Tipp: configure the IP address of your sensor before you add a M7LL ‐ / M70LL ‐ sensor to your network. Use a Web browser for
set up of the IP address, see page 17 for details.

Standard Sensor models send out red laser light less than 1 mW of optical power. They
are laser safety class 2. Depending on the model, special sensors might have laser safety
class 3R, providing higher optical output of up to 5 mW.
Details on laser safety are given on page 20.
For details on other models and modifications please contact MEL Technical Support!

As a demo and test software MEL offers LDMS ‐ LAN (Laser Distance Measurement
Software, network Version). You will receive a copy of the software with your
evaluation unit, the manual is available as download from the MEL ftp server.
This software is easy to use. It offers in the basic version some measurement capability.
On request MEL will provide software for enhanced measurement taks with interfaces
to various control systems. For further details contact MEL Technical Support.
