The DS9097 COM port adapter is a simple, low-cost passive adapter which performs RS-232C (±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. It can also read all EPROM-based iButtons. The serial port must support a data transmission rate of 115.2kbps in order to create the 1-Wire® time slots correctly. Nearly all PCs support the required data rate and are fully compatible with the DS9097. Since an 8-bit character (6 data bits plus start and stop bit) on the RS-232 port operating at 115.2kbps is used to form a single 1-Wire time slot, the maximum effective 1-Wire transfer rate is 14.4kbps (regular speed).

Most customers will want the DS9097U which generates the 1-wire timing signals directly, without requiring direct host computer intervention.
