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

2. Hardware description
This USB to RS-232 converter (TTL-Level) is suitable for e.g. debugging on
microcontroller circuits. Also your processor board will be protected by galvanic
isolation.
This little USB-Stick transmits serial data with TTL-Level (e.g. debugging
informations) on the USB port. Normally there are only TTL-Signals available on
serial ports by processors. With this tool these signals can be comfortably
displayed on your PC or notebook. The “sensitive TTL-Signals” will be savely
connected by galvanic isolation to a PC.
