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.

2.1. Quick installation

2.1.1. Step 1 - Installation of the software and driver

Now install the driver DELIB library with the file "delib_install.exe" from the supplied
DEDITEC-Driver CD.

These can be found in the "\zip\DELIB\delib_install.exe" on the DEDITEC-Driver
CD.

Note: On our website www.deditec.de you can always find the latest DELIB driver
version.

2.1.2. Step 2 - Connecting of the module

Connect your PC via USB cable to the USB connector of the module.

After about 20 seconds, the module is detected by the driver and can now be
tested and operated.

2.1.3. Step 3 - Testing the connection and the module

In the Start menu, see "Start -> All Programs -> DEDITEC -> DELIB -> Sample
Programs" you will find some example programs to test your module.

2.2.5. Outputs

2.2.5.1. Relay outputs

The relays are able to switch voltages up to 36V. The max. current is 1A at a max.
power of 15W.

Additionally, the relays provide a safe electrical isolation of the module to the
connected equipment.

2.2.5.2. Timeout protection

The timeout-protection gives the possibility to switch-off automatically the outputs
to prevent damage. This takes place, if in a predefined time frame any
communication with the module was possible. Reasons could be cable disruption,
PC-crash and so on. This way damage control, surcharge of connected equipment
and risk of accidents can be avoided.

2.2.5.3. Visual control of the outputs (depends of module)

The state of each output is directly signalized by a separate LED. This simplifies to
detect and rectify wiring errors, because the signals on the cables are directly
observable.

Note: Only available for the USB-RELAIS-8 and USB-RELAIS-8_B module

2.3.5. Inputs

2.3.5.1. Registering short input pulses

Short input pulses between to read-out cycles are registered through an additional
logic and can be separately read-out.

2.3.5.2. Galvanically decouppled through optocouplers

AC input opto-couplers provide a galvanic isolation of the module towards the
connected equipment. They also provide a safe connection to the module for
reverse currents and high voltage peaks.

2.3.5.3. Visual control of the inputs (depends of module)

The state of each input is directly signalized by a separate LED. This simplifies to
detect and rectify wiring errors, because the signals on the cables are directly
observable.

Note: Only available for the USB-RELAIS-8 and USB-RELAIS-8_B module
