DESCRIPTION
The DS9097U–09 is a sophisticated RS232 to 1–Wire
Adapter which performs RS232 level conversion and
actively generates the 1–Wire communication signals.
Together with an adequate TMEX software driver it
enables an IBM–compatible PC to directly read all and
write any non–EPROM iButton devices connected to
the adapter. 1–Wire communication is supported by the
adapter for regular as well as Overdrive speed. The
serial port must support a data transmission rate of 9600
bits/s. Under software control, the adapter can be set up
for RS232 data rates of 19200, 57600 and 115200 bits
per second. The two higher rates are recommended for
communication at Overdrive speed with Overdrive
capable devices connected to the 1–Wire bus. Since the
DS9097U–09 operates in a byte mode, every data byte
received from the RS232 port generates eight time slots
on the 1–Wire bus. At 19200 bits/s data rate the
DS9097U–09 is already faster than the DS9097(E) at
115200 bits/s.
The DS9097U–09 is based on the DS2480 Serial
1–Wire Line Driver chip and therefore is
not a plug–in
replacement for the DS9097 or DS9097E
. The RXD/
TXD Polarity Select input of the DS2480 is tied to Vdd
(non–inverting).
