1. Introduction

1.1. General remarks

First of all, we would like to congratulate you to the purchase of a high quality
DEDITEC product.

Our products are being developed by our engineers according to quality
requirements of high standard. Already during design and development we take
care that our products have -besides quality- a long availability and an optimal
flexibility.

Modular design

The modular design of our products reduces the time and the cost of
development. Therefor we can offer you high quality products at a competitive
price.

Availability

Because of the modular design of our products, we have to redesign only a
module instead of the whole product, in case a specific component is no longer
available.

1.2. Customer satisfaction

Our philosophy: a content customer will come again. Therefor customer
satisfaction is in first place for us.

If by any chance, you are not content with the performance of our product,
please contact us by phone or mail immediately.

We take care of the problem.

1.3. Customer response

Our best products are co-developments together with our customers. Therefor
we are thankful for comments and suggestions.

I/O Access

CPU-access to the connected I/O modules.

The Ethernet module has a series of control LEDs. They are used for easy visual
indication of various state functions.

While switching the module on, in normal operating mode, the module should
signalize the following sequence:

approx. 20 sec after switching the module on, LED 1 and 2 are flashing briefly.

-> Operating system has been loaded successfully.
Then LED 3 is on permanently and LED 1 is flashing. -> Module is ready.

3. Configuring the module

3.1. Configuration via DELIB Configuration utility

This method allows a simple configuration of the product. Following basic
values can be changed.

Module name
IP address
Net mask
Default gateway
DNS server

Additionally with this tool all DEDITEC ethernet devices in the LAN network are
displayed.

The following pages describe how it works...

Configuring the module |Seite 13

Start DELIB Configuration utility as follows:

Start -> Programs -> DEDITEC -> DELIB -> DELIB Configuration Utility

1.

Module Selection: select RO-ETH

2.

Find and configure RO-ETH Module

Configuring the module |Seite 14

1.

Scan RO-ETH modules: So you can find all DEDITEC ETH modules on local
ethernet stream. Therefore we use an ethernet protocol which will not be
routed. Because of that you can configure only modules which are connected
to the bus. The advantage of this method is, that you can find modules which
are not in the same sub net, of which you are configuring.

2.

Click on the module, which you want to configure.

Configuring the module |Seite 15

Here you can change the module name according to your wishes

1.

You can change module name, IP address, net mask, default gateway and
DNS server.

2.

Write new Values to Module.

Notice:

At the configuration of the RO-ETH module should be paid attention to the IP
address. It has to be in the same IP segment in which the control PC is. Of
course you must not select an already used IP address.

If the standard IP address of the module is not from the address range of the
network, the module will not be reachable by TCP/IP at the moment. Problems
of accessibility will also occur, if the IP address is already used. However the IP
address and the net mask of the ethernet module are configurable by this utility.
Alternatively you can connect the module to the PC and set the IP address and
the net mask directly. After the accessibility is given, the further configuration is
ensued by a browser via the integrated web server of the ethernet module.

To these belongs ask your system administrator.

3.2. Configuration via internal web server

The RO-ETH module has an own web server by which it can be configured, too.

3.3. Factory settings

The factory settings of the ethernet module include following settings:
IP address: 192.168.1.1

The factory settings can be restored by pushing the left button -> see chapter

5.2

IP address 192.168.1.1
Subnet mask 255.255.255.0

The default value of the IP address is: 192.168.1.1

Left Button: Restore IP address to default (192.168.1.1):

To restore the IP address proceed as follow:

Push the button at least 5 sec.
After that, the left LEDs "CPU Activity" and "Interface Activity" should be

flashing four times (confirmation of receipt)
After this, the module has following settings:

IP address 192.168.1.1
Subnet mask 255.255.255.0
Standard gateway 192.168.1.254

5.2. Restore firmware

To restore the firmware to default value proceed as follow:

Right Button: Restore firmware to factory settings

To restore the firmware to factory settings proceed as follow:

Press the button at least 10sec.
After this, the three LED‘s “CPU Activity”, “Interface Activity” and “Status”

should be flashing four times (confirmation of receipt).
After this, the module restarts.

The firmware and configuration of the factory settings are now active again!

6. Software

6.1. Using our products

6.1.1. Access via graphical applications

We provide driverinterfaces e.g. for LabVIEW and ProfiLab. The DELIB driver
library is the basis, which can be directly activated by ProfiLAB.

For LabVIEW, we provide a simple driver connection with examples!

6.1.2. Access via the DELIB driver library

In the appendix, you can find the complete function reference for the integration
of our API-functions in your software. In addition we provide examples for the
following programming languages:

C
C++
C#
Delphi
VisualBasic
VB.NET
MS-Office

6.1.3. Access via protocol

The protocol for the activation of our products is open source. So you are able
to use our products on systems without Windows or Linux.

Software | Seite 26

6.1.4. Access via provided test programs

We provide simple handling test programs for the most important functions of
our products. These will be installed automatically by the installation of the
DELIB driver library.

So you can test directly e.g. relays or you can check the voltage of an A/D
converter.

6.2. DELIB driver library

6.2.1. Overview

The following figure explains the structure of the DELIB driver library

The DELIB driver library allows an uniform response of DEDITEC hardware with
particular consideration of the following viewpoints:

Independent of operating system
Independent of programming language
Independent of the product

Program under diverse operating systems

The DELIB driver library allows an uniform response of our products on diverse
operating systems.

We has made sure, that all of our products can be responded by a few
commands.
Whatever which operating system you use. - Therefore the DELIB cares!

Software | Seite 28

Program with diverse programming languages

We provide uniform commands to create own applications. This will be solved
by the DELIB driver library.

You choose the programming language!

It can be simply developed applications under C++, C, Visual Basic, Delphi or
LabVIEW®.

Program independent of the interface

Write your application independent of the interface !
Program an apllication for an USB product of us. - Also, it will work with an

ethernet or RS-232 product of us !

SDK-Kit for Programmer

Integrate the DELIB in your application. On demand you receive an installation
script for free, which allows you, to integrate the DELIB installation in your
apllication.
