1. Introduction
This document describes in a simplified way individual topics of the use of the KeTop Wireless
System. It does not replace the study of the project engineering manual, where the individual
topics are described and explained in detail. Information on sources of danger, hazardous
situations and the proper use must also be read there.
2. System description
The KeTop Wireless System consists of a base station and a handheld terminal.
Illustration: Base station and handheld terminal
There are two states for the handheld terminal
 It is connected to a base station (paired)
 It is not connected to a base station (unpaired)
The safety devices on the handheld terminal (emergency stop and enabling switch) are only active in
the paired state. The emergency stop on the base station is always available. The network with which
data is exchanged is not part of this state.
Illustration: Emergency stop not illuminated
Illustration: Emergency stop illuminated
How to switch between these two states, see chapter 4.

5. Configuration
To configure the base station and/or the handheld terminal, these two must first be connected (see
chapter 4). For the configuration, the DeviceConfig tool is available on the handheld terminal, with
which both the base station and the handheld terminal can be configured.
Illustration: Windows Desktop with DeviceConfig tool
After starting the DeviceConfig tool, different menus can be selected.
Illustration: Main menu DeviceConfig tool

5.1. Assign base station name
Each base station should be given a name. The default name is the serial number of the base station.
The name always appears when connecting and disconnecting the base station with the handheld
terminal.
Note: To be able to perform this configuration, the base station and the handheld terminal must be
connected. The connection must be established before starting the DeviceConfig tool.
Note: For the name please use only letters and numbers and no special characters.
First select the base station in the DeviceConfig tool main menu.
Illustration: DeviceConfig tool main menu
Then select the dialog for entering the name of the base station.
Illustration: Base station submenu
To enter the name, press the keyboard icon next to the name. An on-screen keyboard opens for
entering the name. The name dialog also indicates the base station to which the handheld terminal is
connected (paired). Once the name has been entered, the dialog is exited via "Write to basestation".
This command writes the name to the base station.

5.2. Set network mode
Next, the Network Mode should be set, in which state of the system over which network data should
be exchanged. For this purpose the network mode can be set.
Illustration: DeviceConfig tool main menu
Illustration: Network submenu

13
Illustration: Modedialog
But what can be set here? There are different deployment scenarios for the KeTop Wireless System,
which can be configured here. In the following, the scenarios are briefly described and how they can
be configured in the DeviceConfig tool.
Scenario „Industrial tablet“:
The handheld terminal is operated in the hall network and there is no connection to a base station -
comparable to a tablet. There is only data traffic and no secure connection. In this case, no access to
information from the base station is possible.
Illustration: Scenario description „Industrial tablet“
The corresponding configuration in network mode looks like this, a connection of the handheld
terminal to the base station is not possible in this mode, the emergency stop and the enabling switch
are not available, the emergency stop will never be illuminated, a base station is not necessary.
Illustration: Configuration for scenario „Industrial tablet“
Scenario „Cable replacement“:
The handheld terminal is only operated with the base station. Data traffic only takes place if the two
have established a secure connection after being paired. In the paired state, the emergency stop and
the enabling button are available on the handheld terminal. This is indicated by the emergency stop
lighting.

14

Illustration: Configuration for scenario „Cable replacement“
Scenario „HMI focus“:
The handheld terminal is only operated in paired mode with the base station. In unpaired mode, data
traffic is handled via the hall network. In the paired state, the emergency stop and the enabling button
are available on the handheld terminal. This is indicated by the emergency stop lighting.
Illustration: Scenario description scenario „HMI focus“
Illustration: Configuration for scenario „HMI focus“
Scenario „SCADA focus“:
The handheld terminal always uses the WLAN of the hall network for data traffic. The safe connection
can exist in parallel. In the paired state, the emergency stop and the enabling button are available on
the handheld terminal. This is indicated by the emergency stop lighting.

5.3. Network configuration
Handheld terminal network through the base station
If the base station is selected in the network mode, the connection configured here is used. From the
point of view of the network, the base station is transparent and is therefore not considered a network
subscriber. From the point of view of the application on the handheld terminal, the handheld terminal is
in the network to which the base station is connected. The SSID of the WLAN between the base
station and the handheld terminal is generated from the serial number, among other things; the
password is generated, is not visible and is exchanged between the base station and the handheld
terminal. However, the band and the channel can be parameterized from the established WLAN
connection.
Illustration: Handheld terminal in the base station network
Note: To be able to perform this configuration, the base station and the handheld terminal must be
connected. The connection must be established before starting the DeviceConfig tool.

5.4. Fast Response Operator Controls (Fast Response Buttons)
[Option]
Fast Response Operator Controls are a function where the operator controls of the handheld terminal
are directly assigned to outputs of the base station and the value of the controls can be tapped directly
at the outputs during operation. Currently this is only implemented for the keys.
The outputs are in the base station at the terminal strip Fast Response Buttons Pin 6 (DO14) to Pin 20
(DO1), whereby Pin 5 and Pin 11 provide GND..

18
Illustration: Image of the base station with terminal strip Fast Response Buttons (Pin 5 to 20)
The configuration is then done in the DeviceConfig tool.
Note: To be able to perform this configuration, the base station and the handheld terminal must be
connected. The connection must be established before starting the DeviceConfig tool.
Illustration: DeviceConfig tool main menu
Then select the Fast Response Buttons configuration dialog..
Illustration: Base station submenu
The configuration is done in such a way that for each of the outputs used (DO), it is defined which key
of the handheld terminal switches it. For definition, press the "KEY" button next to the key number and
then press the desired key. The scancode of the key is filled.

6. Projection
For the projection of the visualization application, the KeTop Safe Wireless System is the same as a
wired KeTop system. Both the access via control interfaces to the operator controls and the
connection with PLCs, computers or other data sources is made via the network connections. It should
only be noted that when switching between the two network options, connections are interrupted and
must be reestablished.
6.1. OperatorControlsInterfaces
Refer to the manual of the respective controller connection to the operator controls.
6.2. Access to elements of the KeTop Safe Wireless System
The elements of the KeTop Safe Wireless System can be accessed via the HWApi. This library is
supplied as a DLL and can be used in C, C++ and C# implemented applications. Further information is
available from KEBA Support.
6.3. Data connection
See the manual for the respective visualization projection or programming.
7. Operation
During operation, the base station and handheld terminal are normally connected or disconnected
depending on the usage scenario. This is described in chapter 4. If it is necessary to check to which
base station a handheld terminal is connected, it is possible to check this via the Ident Key.
Another application is the pressing of the emergency stop or the enabling switch during operation. This
activates electrical safety mechanisms; when the emergency stop is pressed, this is also visualized by
the base station.
For exceptional situations where the base station and the handheld terminal cannot be brought into
close proximity, there is a function for connecting or disconnecting both devices "remotely" (remote
pairing and remote unpairing). However, a line of sight must always be available between the two
devices.
