RS232-ADC
The RS232-ADC16/24 device is designed to give simple access to external sensors and peripherals over a standard RS232 connection. There is no need for any additional drivers when using Windows, DOS or Linux systems. Microcontroller only needs a simple implementation of their UART interface.

Instructions sent to the device have an human readable form allowing manual traffic checking for debugging proposes. To integrate RS232-ADC into your application, a C-library is provided with the device bearing the work of protocol parsing and packet construction.
The device comes in two versions, one with 16-bit and one with 24-bit ADC channels. These versions are named respectively to their ADC channel resolution RS232-ADC16 and RS232-ADC24.

One possible application would be in a liquid distribution system. With the help of the RS232-ADC, valves can be controlled by a PC dependent upon water pressure. In this case, the pressure is measured by an analog input and the valve controlled by a digital output. In addition, the proper functioning of the valve could be proofed by a digital input. Just one RS232 interface is required on the PC side, which can also serve as a power supply. The module's regulated voltage of 3.3V can also be used by the sensors.
