2 About the Product
2.1 Intended Use
The BlitzFunk product line is a wireless networking solu,on designed to deliver
highly reliable real-,me wireless connec,vity for industrial environments. It may
serve as a replacement for wired Ethernet in industrial applica,ons and enables
wireless connec,ons for mobile systems.
A BlitzFunk network requires at least one access point and one or more clients.
The system is fully transparent to common industrial Ethernet protocols (e.g.,
PROFINET, PROFIsafe, EtherNet/IP, OPC UA) and func,ons as a Layer 2 switch.
Unlike tradi,onal wireless Ethernet bridges, it is not restricted to point-to-point
links.
BlitzFunk is ideal for small to medium-sized networks with 1 to 20 clients, and can

3 Device Installation
3.1 Hardware Installation
Before using client devices, connect all included antennas to their designated
antenna ports. Only use antennas that come with the device. Antennas should be
fastened by hand ,ght or ,ghtened with a maximum torque of 0.9 Nm. Access
point devices come with antennas already aaached.
WARNING: Powering the device without connec,ng all antennas to the
RP-SMA ports may cause damage. Using only some antennas can result
in the device not func,oning as intended.
,
WARNING: Only antennas provided with this device shall be used. The
use of any unauthorized or non-approved antennas may result in non-
compliance with regulatory requirements and could cause harmful
interference. Unauthorized modifica,ons or subs,tu,ons may void the
user’s authority to operate this equipment.
Tip: For installa,ons in ,ght spaces, such as interior-mounted
equipment, clients can operate with reduced reliability by rou,ng only
the RX/TX ports to the exterior (e.g. ANT1 and ANT3). The other
antennas are receive-only, they do not need to be RF-terminated if
unused.
3.2 Antenna Orientation and Device Positioning
The angle of the antennas can impact both coverage and connec,on stability. For
maximum range with line-of-sight, the antennas of access point and client must be
aligned parallel to each other.

BlitzFunk User Manual
Release 2026/4
Figure 6 Recommended antenna posi,oning
Avoid placing antennas inside or behind metallic enclosures, such as control
cabinets or within automated guided vehicles, as this will degrade signal quality
significantly. If the device must be installed inside a metal enclosure, use RP-SMA
extension cables to route the antennas to the outside.
Figure 7 Antenna moun,ng outside of metallic enclosures
The achievable range of the system depends on environmental condi,ons. Op,mal
range is typically achieved when there is a clear line of sight between the access
point and the client.

WARNING: This device and its antenna(s) must not be co-located or
opera,ng in conjunc,on with any other antenna or transmiaer.
This equipment should be installed and operated with a minimum
distance of 20cm between the radiator & your body.
3.3 Wall or Ceiling Mounting
At the desired loca,on, the device should be securely mounted to a wall or ceiling
using its integrated moun,ng holes.
WARNING: To prevent injury from falling equipment, the device should
be secured by an expert. Depending on the material ok he wall or
ceiling, suitable wall anchors have to be selected. It always needs to be
verified that the moun,ng surface is stable and capable of bearing the
weight of the device.
3.4 Power and Data Connection
Connect both the client and access points to power. They must be supplied with
an external DC power source via the DC port. An access point device can
alterna,vely be powered through its ETH/PoE port using Power over Ethernet
(PoE).
WARNING: To ensure the safety of the product, the devices shall
always be supplied with ES1 and LPS | PS2 | Class 2 power sources.
Pour garan/r la sécurité du produit, les appareils doivent toujours être alimentés par

Tip: If both DC and PoE are connected, the device will draw power from
the DC supply. In this configura,on, PoE will act as a backup in case the
DC supply fails.
Connect the data ports of the devices to the end devices which shall establish
connec,on. In systems with mul,ple access points, the ETH ports of all access
points must be interconnected, for example via a network switch. To ensure proper
synchroniza,on between access points, the network infrastructure must support

4 Device Configuration
Before data transmission can take place, when powering the devices for the first
,me or when replacing exis,ng ones, the system must be configured.
Configura,on is performed using the web-based interface of the access point,
which can be accessed from any standard, up-to-date web browser. The following
sec,ons explain the available func,ons of the configura,on interface using
example setups.
Tip: Issues that may occur when using the system for the first ,me are
summarized in chapter 8 (ref. Troubleshoo<ng).
4.1 Accessing the Configuration Interface
To access the configura,on interface, a computer is required with:
• a web-browser
• one free Ethernet port
Connect the computer via Ethernet to the access points that are awai,ng
configura,on. Power must be supplied to the access points.
Clients that require configura,on must be powered on and within wireless range
of at least one access point. Clients must not be connected to the access points by
cable, as this will create a network loop once the system is configured.
By default, the configura,on interface is accessible at:
Tip: The system can be configured while already installed in its final
loca,on. Although a temporary connec,on to a computer is needed for
configura,on, the cabling used during configura,on is the same as in
the system's opera,onal state.

BlitzFunk User Manual
Release 2026/4
In networks with more than one BlitzFunk access point, the access point with the
lowest serial number is automa,cally designated as the coordina,ng access point
(coordinator). The web interface is provided by the coordina,ng access point.
In the factory default configura,on, the coordina,ng Access Point operates with
an integrated DHCP server enabled, assigning IP addresses in the range 10.5.0.12
to 10.5.0.254. The IP address and DHCP server sesngs of the coordina,ng Access
Point can be configured through the configura,on interface (ref. Changing the IP
Adress Behaviour).
Ensure that the computer used for configura,on has an IP address in the same
subnet as the coordina,ng access point.
4.2 Password Protection
By default, the configura,on interface is accessible from any device within the
same network. To restrict access, you can set a password in the Password tab of
the configura,on interface. This ensures that only authorized users can modify
system sesngs.

To set a password, click the Enable toggle, enter the desired password, and click
Apply. You can choose whether read access (viewing without making changes) is
allowed without a password or not.
Tip: Please note that the HTTP connec,on to the web interface is not
secured. For security reasons, ensure that the chosen password is not
used anywhere else.
Aker applying, you are automa,cally logged in. You may log out via the Log Out
Buaon.
4.3 Assignment of Channel Groups
Before data can be transmiaed between devices, they need to be assigned to a
channel group. To do this use the Channels & Devices tab.

BlitzFunk User Manual
Release 2026/4
BlitzFunk devices communicate within channel groups. A channel group uses two
redundant 20 MHz channels for data transmission. To create a channel group, first
select two opera,ng channels by clicking Create Channel Group.
To increase the reliability of the system, it is recommended to separate the two
channels with more than 100 MHz separa,on. Adjacent channels cannot be
selected.
For device management, BlitzFunk uses channel 149 at 5745 MHz. This channel is
currently fixed but will be made configurable in a future.
Tip: The achievable range depends on the legally permiaed
transmission power. At 2.4 and 5.2 GHz, greater ranges can be expected
than at 5.8 and 6 GHz. Channels in the laaer frequency ranges are
therefore referred to as Short Range.
Tip: The frequency bands with shorter range at 5.8 GHz (5765 – 5865
MHz) and 6 GHz (5955 – 6415 MHz), are generally less crowded than
other frequency bands and therefore more reliable than the lower
frequencies.

Add devices to a channel group by dragging and dropping them into it, or by
selec,ng the desired devices using the Add Device buaon. Available devices are
shown at the boaom in the Available Devices sec,on. Access points are always
available when connected via Ethernet. Clients are available when they are not
assigned to any channel group (indicated by the yellow PWR LED), or when they
cannot find an access point belonging to their channel group.
The number of clients in a channel group affects both latency and data throughput.
The first client is connected with a data rate of 6 Mbit/s and a maximum one-way
latency of 4 ms. Each addi,onal client increases latency by 2 ms. The data rate is
evenly distributed among all clients in a channel group. Some example values are

4.4 Extending Coverage with Additional Access Points
To extend the coverage of a BlitzFunk network, addi,onal access points can be
assigned to a channel group. No addi,onal channels are required for this since the
access points coordinate with each other and use the same two channels.
Clients can move freely between access points within the same channel group
without interrup,ons and without affec,ng latency or data rate (latency-free
roaming).
For a stable connec,on, it must simply be ensured that the signal strength is
sufficient at every possible client posi,on (ref. Link Status Monitoring). To achieve
this, an unobstructed line of sight to at least one of the access points should always
be maintained. When using channels in the 6 GHz band, the distance to the nearest
access point should be less than 40 meters.
Device Configura,on
30
BlitzFunk User Manual
Release 2026/4
To use this func,onality, access points need to be connected via Gigabit-Ethernet
(ref. Power and Data Connec<on) and placed with overlapping coverage. The
connec,ng switch should ideally not have to process any other data traffic and
should not exceed a latency of 50 microseconds for frame sizes up to 1522 bytes.

coverage

4.5 Increasing Capacity with Additional Access Points
To increase the data rate per client and reduce latency, mul,ple channel groups
can be operated in parallel. Latency and data rate scale independently for each
channel group. Unless separated from each other by virtual networks (ref.
Segmenta<on into Virtual Networks (VLANs)), a client can exchange data with all
other clients, regardless of which channel group they belong to.
For a setup with mul,ple channel groups, a separate access point is required for
each group. The access points must be connected to each other via Gigabit-
Ethernet (ref. Power and Data Connec<on).

and reduce latency
In the configura,on interface, create mul,ple channel groups and assign one
access point to each group. Add clients to the corresponding channel group and

4.6 Seperation into virtual Networks (VLANs)
Clients in a BlitzFunk network can be isolated from one another using virtual
networks (VLANs). This allows independent applica,ons to operate on the same
infrastructure without mutual interference. It also helps limit the impact of
cybersecurity incidents and reduces the scope of broadcast frames, thereby
providing more capacity for each applica,on.
VLAN-specific sesngs are configured in the Virtual Networks tab.
BlitzFunk implements VLANs according to the IEEE 802.1Q standard. Data is
assigned to a VLAN by means of an addi,onal field (the so-called VLAN ID) in the
Device Configura,on
33
BlitzFunk User Manual
Release 2026/4
header of the Ethernet frame. A VLAN is iden,fied by a number between 1 and
4095.
For each client, the following VLAN op,ons can be assigned:
Mode FuncAon
Standard Devices connected to the client receive only data without
a VLAN ID or data with a VLAN ID 0 (e.g. PROFINET). Data
entering the client via Ethernet is accepted only if it has
no VLAN ID or a VLAN ID 0 and is then forwarded to the
access point. For traffic with VLAN ID 0, the complete
802.1Q header is transmiaed unchanged.
Virtual Network
Devices connected to the client receive only data with
the matching VLAN ID. The complete 802.1Q-Header
including its VLAN ID is removed by the client when
outpusng data via Ethernet, so the connected devices
do not need to process VLAN IDs. Data entering the
client via Ethernet without a VLAN ID is assigned the
appropriate ID and forwarded to the access point. Data
entering the client via Ethernet with an 802.1Q-Header,
the VLAN ID is replaced with the configured value.
Trunk
All data is forwarded regardless of its VLAN ID. The
complete 802.1Q header is transmiaed unchanged. This
allows VLAN-capable switches to be operated on this
client.
Device Configura,on
34
BlitzFunk User Manual
Release 2026/4
Access points are always in trunk mode. If clients have been assigned to a virtual
network and this virtual network needs to be accessed on the access-point side, a
VLAN-capable switch must be used.
Tip: The DHCP server and HTTP server of the access point are not part
of any VLAN. This means that only clients in standard mode or trunk
mode, as well as devices connected to these clients, can obtain an IP
address from the built-in DHCP server. Likewise, the configura,on
interface is only accessible through clients in standard or trunk mode.
In the following example, a virtual network is set up for each client in order to
create logically separated point-to-point connec,ons at the Ethernet level
between controllers at the access point and a remote I/O module at each client.

client, it must contain the corresponding VLAN ID (in this example VLAN ID 1000
or 1001).

BlitzFunk User Manual
Release 2026/4
To allow the controllers to reach the clients in their VLAN, the managed switch
between the access point and the controllers must be configured as follows:
• The port connected to the access point must be configured to
transparently forward any VLANs (trunk mode).
• The ports connected to the controllers must each be assigned to one of
the previously created VLANs (in this example 1000 or 1001) and
configured to apply the corresponding ID to incoming traffic and remove
the ID from outgoing traffic (untagged mode).
4.7 Changing the IP Address Behavior
Access to the configura,on interface requires the coordina,ng Access Point to
have an IP address. In addi,on, IP addresses can be assigned to individual clients,
for example for diagnos,c and monitoring purposes.
Tip: Assigning IP addresses to clients is only intended to make the
devices themselves reachable, for example for diagnos,c purposes.
User data transmission through the BlitzFunk network operates
transparently on Layer 2 and does not require IP address configura,on
on client devices.
The sesngs for the IP address behavior are located in the IP Addresses tab of the
configura,on interface.

In the default sesng No IP, a client does not have an IP address assigned. For
diagnos,c purposes, the op,ons Static IP, which assigns a fixed IP address to the
client, or DHCP Client, where the client obtains an address using the DHCP
protocol, can alterna,vely be used. The IP address of a client can, for example, be
used to verify network connec,vity to the device using ping.
If a client has obtained an IP address using the DHCP Client op,on, a new IP
address can be requested before the current lease dura,on expires by pressing the
buaon next to the displayed IP address.

Hinweis: When a device (coordinator or client) is operated as a DHCP
client, IP addresses are assigned automa,cally via the network. This
generates addi,onal network communica,on, which may affect real-
,me communica,on performance depending on overall network load.
For applica,ons with par,cularly high real-,me requirements, the use
of sta,c IP addresses or opera,on without an IP address is therefore
recommended to ensure the most consistent and determinis,c
communica,on possible.

8 Troubleshooting and Support
8.1 Troubleshooting
Problem: Web interface not accessible
It takes about 30 seconds aker powering on an access point before the web
interface becomes available. When devices are in setup mode, which is indcated
by a yellow PWR LED, the interface can only be accessed through access points,
not from client devices. Make sure the URL in your browser is h0p://10.5.0.1 and
not h0ps://10.5.0.1. If another DHCP server is ac,ve on the network, locate the
access point's IP address in the DHCP lease list.
Problem: New client does not appear or disappears occasionally (grey status
indica<on or device is completely missing in the web interface)
This is likely caused by low signal strength. Verify that all antennas are properly
mounted on both access points and clients. Antennas should be ,ghtened hand
,ght or using a torque of 0.9 Nm. Try moving the client closer to the nearest access
point or install another access point nearby. Avoid shielding antennas with metallic
objects like control cabinets or machine housings. For devices mounted in metal
enclosures, use low-loss RP-SMA cables rated up to 7 GHz to posi,on the antennas
outside.
Problem: Addi,onal access point does not appear in the web interface
For coordina,on between the access points, VLAN ID 512 is used. If you are using
managed Ethernet switches to connect the access points, ensure that VLAN ID 512
is forwarded by the switch.
Problem: Occasional communica<on errors and outages
This may be due to system overload, weak signal strength, or interference from
other wireless networks opera,ng on the same channels. In the web interface,
open the client’s status and check the reported values (ref. Link Status Monitoring).
If buffer overflows are rising, the system is overloaded and must be supplied with
less data. If the receive power drops below -80 dBm and packet loss increases,
refer to the signal strength ,ps above. If receive power is good (above -60 dBm)
but packet loss is s,ll high, interference is likely. Try using different channels with
at least 80 MHz spacing.
Problem: Unexpected con<nuous ac<vity on TX and RX-LEDs in combina<on with
communica<on errors and difficul<es accessing the web interface
Troubleshoo,ng and Support
58
BlitzFunk User Manual
Release 2026/4
The system is likely overloaded. If you do not expect high traffic from the
applica,on, check your network for loops. Ensure that none of the clients are
connected to the access points using a wired connec,on.
Problem: Otherwise inexplicable behavior
Unexpected behavior can occur during undervoltage condi,ons. If the device is
powered through the DC connector, ensure that the supply voltage does not drop
below 10 volts. When using Power over Ethernet (PoE), make sure the PoE source
(e.g. a PoE switch) is compliant with at least IEEE 802.3af and is capable of
supplying sufficient power. Note that not all switches can power every port
simultaneously at full load.
Do not power off the device during firmware updates or configura,on changes. In
rare cases, unexpected behavior may also result from sokware bugs. You can
always recover from invalid configura,ons by performing a factory reset (ref.
Factory Reset).
