§1. Short description To facilitate and standardize the task of driver creation for data acqusition devices the company RTS-Ukraine offers an integrated DWizard drivers development environment. This environment represents convenient user interface for creation, debugging and integration of a driver created to Silver 2 package. All the programmer has to do is to instrument interface with particular hardware.
§2. Short characteristics
- Most assemblies types: ISA, PCI, sequential port and others (drawing 1);
- Debugging;
- Visual driver creation and editing possibility (drawing 6);
- integration into a Silver 2 package

§3. Basic points Interaction of user software with a driver is shown on the following drawing:
| Рисунок 2. Взаимодействие прикладного пользовательского приложения с драйвером |
User software using access library interface conducts a driver enquiry. The driver kernel using equipment inquiry functions provides data access. Equipment inquiry functions may be instrumented with a help of DWizard.

Data accessible to user application is represented on 'Data channels' of different types. There are 5 types of channels at all: analog input/output channel, discreet input/output channel and complementing input channel.
| Рисунок 4. Каналы данных |
Each data channel is characterized with a number of parameters: access type (input/output), channel type (analog, discreet), signal scale and others:
