FEATURES

§ Provides a simple, low-cost interface to an

RS232C COM Port for reading and writing

iButton^TMdevices (DS9097E required for

programming DS198x Add-Only iButtons)

§ Adapter is powered entirely from an RS232

interface (DS9097E may require optional

auxiliary 12V supply)

§ Standard DB-9 (DSD9097) or DB-25

(DS9097E) female connector for mating the

adapter to the COM Port of a computer and

RJ-11 connector for easy attachment of a

probe such as the DS9092GT

§ DS9097E has an additional 2.1 mm male

power jack to allow for an auxiliary 12V DC

supply for programming Add-Only iButtons

Pin assignment DS9097, DB-9

TXD (3), RXD (2), DTR (4), PC-Ground (5);

Pin assignment DS9097E, DB-25

TXD (2), RXD (3), DTR (20), RTS (4), PC-

Ground (7); all other pins not connected

Auxiliary supply should be a regulated 12V

@ 10 mA minimum, center=GND, outer

equivalent)

DESCRIPTION

The DS9097 COM Port Adapter is a simple, low-cost passive adapter which performs 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. It can also read all EPROM-based iButtons. The serial

port must support a data transmission rate of 115.2 kbits/s in order to create the 1-Wire^TMtime 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 RS232 port operating at 115.2 kbits/s is used

to form a single 1-Wire time slot, the maximum effective 1-Wire transfer rate is 14.4 kbits/s (regular

speed). Details on the operation of the DS9097 including software examples are found in Application

Note 74, Section V.
