The product is a simple, low-cost adapter that converts RS232C (±12V) level conversion, allowing an iButton probe to be connected to the serial port of a computer so that a non- EPROM iButton can be read and written directly.
The Dallas Semiconductor DS9097 COM Port Adapter is a simple, low-cost passive adapter that performs RS232C level conversion. It allows an iButton probe to be connected to the serial port of a computer to read and write non-EPROM iButtons directly, as well as read all EPROM-based iButtons. The adapter is powered entirely from the RS232 interface and features a standard DB-9 female connector.
