1. Description

The I2C-RS232-Adapter is a universal usable I2C to RS232 converter. With the

Adapter as I2C-Slave, several RS232 devices (e.g. PC, microcontroller) can be

connected to one I2C bus, or several I2C-Devices (Master) can be connected to one

RS232 device.

The slave address can be programmed freely over the serial interface. The default

0xFE

slave address is

the I2C-RS232-Adapter and then transmitted through the serial interface. A data

packet can be maximal 128 bytes.

The data, which a serial device receives (e.g. PC, microcontroller), can be processed

and then sent back to the I2C-RS232-Adapter. Here the data packet can be also

maximally 128 bytes. So that the I2C-RS232-Adapter can get the function of a

master, the I2C-RS232-Adapter controls two Interrupt outputs. An Interrupt output

can be selected over the serial interface while sending data to the adapter.

Two types of this adapter are available:

I2C-RS232-Adapter RS (Part No. #020101):

This type is controlled only via the serial interface (RS232). The

communication is done through ASCII commands (see page 15).

I2C-RS232-Adapter IC (Part No. #020102):

This type is controlled only via the I2C-Bus. The communication is done

through I2C commands (see page 8). The RS232 interface is transparent.

With the many possibilities of the Adapter it is very simple to define/program own

I2C-Slaves when connected to a PC or a microcontroller.

Therefore the adapter is suitable for developers, who would like to develop and/or

test own I2C-circuits. The Adapter can be a PCF8574, PCF8574A, temperature sensor

or any other slave with any (7-bit) slave address.

With a PC or microcontroller the Adapter can be used also to control devices with

I2C-Interface (Master). For software development, a Delphi component, a DLL,

examples and data transmission protocol of the Adapter are available for developer.

When using the software interfaces, the Adapter can be integrated very simply into

own applications
