1 General information
1.1 Concerning the contents of this document
This manual contains information about the installation and commissioning of Baumer PosCon OXH7 sensors
with TCP/IP interface.
It is a supplement to the mounting instructions supplied with each sensor.
1.1 Intended use
The Baumer PosCon OXH7 sensor measures heights of objects. It was especially developed for easy
handling, flexible use, and precise measurement.
1.1.1 Functional principle of triangulation
The sensor works on the laser triangulation principle.
By means of special optics, a laser beam is enlarged
into a line and projected to the surface of the object to
be measured. Using the multi-lens system, the
reflected light from this laser line is projected onto a
matrix. From this matrix image, a controller calculates
the distance to every individual measuring point.
The measuring value is calculated in accordance with
the selected function. Thanks to the new Baumer
technology, the object height is always output
correctly, independent of the object's position in the
measuring field.
Read these operating instructions carefully and follow the safety instructions!

2.1 Sensor reference levels
To ensure that the sensor is easy to align during installation, reference levels have been defined. The laser
beam of the sensor runs parallel (//) to level R3 and is at a right angle to levels R1 and R2. Levels R1, R2, and
R3 serve as a reference for sensor alignment during installation. The "Left" and "Right" alignment must also
be observed.

2.2.1 Blind region
The region from the sensor level R2 up to the start of measuring range Sdc is called the blind region, i.e., the
sensor cannot detect any objects there.
If there are any objects in this region, this can lead to incorrect measurement values.

2.2.3 Precise laser alignment with qTarget
The field of view is aligned with the housing reference surfaces at the factory. The beam position in every
sensor is in exactly the same spot, which makes planning and sensor replacement very easy.

2.4 Alignment
To achieve as reliable and exact measurement values as possible, the following hints and tips for mounting
should be followed.
2.4.1 The reference surface
If the height of the object is to be measured from a specific surface or if the sensor is to be mounted at an
angle of up to ±30°, then the reference surface must be teached using the Flex Mount function.
The following points must be satisfied for teaching the reference surface:
•The reference surface must be within the measuring range of the sensor (Sdc-Sde)
•The sensor may be inclined at a maximum angle of ±30° to the reference surface
•The "maximum unevenness of the reference surface"
1
must not exceed the maximum value
•The length of the reference surface must not be less than the "minimum reference surface length"
1

2.4.2 Angled installation (Flex Mount)
The sensor can be installed at an inclination of up to ±30° to the reference surface for the height function. This
is particularly useful when space conditions do not allow any other installation option. See chapter Flex Mount.
After activation of Flex Mount, the sensor axis is no longer relevant. The measurement coordinate system is
now represented by the M and K axes. The height is now measured in the M direction.
Reference point with inclined installation
In the case of angled installation, the reference point (0 mm) of the K axis shifts out of the center of the field of
view or the red visible laser line. Due to inclination of the sensor, the two field of view sections, "Width of field
of view left" and "Width of field of view right", are no longer equal in size.

2.5.3 Initial setup of the Ethernet interface on the computer
Assigning an IP address
To use the device in your network, you must assign a unique IP address to the device.
1. If you have a DHCP server integrated into your network, the IP address is requested from this server.
No additional manual actions are necessary on your part.
2. If a valid IP address cannot be obtained within 15 seconds, the static IP address is used. When the
device is delivered, this is IP address 192.168.0.250 (subnet mask: 255.255.255.0).
Now, link your PC into the same network as the device. If your network does not have a DHCP server, you
may have to adapt the IP address of your PC. With Microsoft ® Windows ® 7, proceed as follows:
1. Open: Start menu →Control Panel →Network and Internet (View network status and tasks) →
Change adapter settings
2. Select your network (e.g., "Local Area Connection") and then the "Properties" entry in the context
menu.
3. Select the "Internet Protocol Version 4 (TCP/IPv4)" entry in the list of elements and then click the
Properties button below the selection list. The following dialog box opens:
Activate the Use the following IP address option and select an address in the range 192.168.0.1-
192.168.0.254 that has not yet been used for the IP address. Enter 255.255.255.0 for the subnet mask
and confirm these settings.
2.5.3.1
NOTE
To avoid network malfunctions, ensure that each IP address is unique within the network
and has not already been assigned.

Identifying an unknown sensor IP address
If you do not know the IP address of the sensor, either because it was assigned via DHCP or the information
about the static IP address is no longer available, you can query the IP address in the following way:
1. Open a Windows prompt
2. Execute the command ping OXH7-[identifier].local. Replace [identifier] either with
the eight-digit order number or the MAC address indicated on the sensor. Example: ping OXH7-
12345678.local or ping OXH7-11-22-33-44-55-66.local
3. Read the IP address (here: 192.168.0.250) from the command output:
Ping is executed for OXH7-12345678.local [192.168.0.250] with 32 bytes of
data:
If you do not gain access to the sensor when you specify this IP address, change the IP configuration of your
PC as follows:
1. Enter an IP address that comes either directly before or after the sensor IP address.
2. Enter 255.255.255.0 as the subnet mask.
3. Confirm the setting.
2.5.3.2
