DESCRIPTION

The DS1411 is a sophisticated RS232-to-1-Wire

conversion and actively generates the 1-Wire communication signals. Together with an adequate TMEX

software driver it enables an IBM-compatible PC or laptop computer to directly read all and write any

non-EPROM iButton devices. The DS1411 has a DS9098P retainer for a single F5 MicroCan

replace the DS9097U-009 or DS9097U-S09, respectively, in applications that use only a single iButton.

1-Wire communication is supported by the adapter for standard 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. Since the DS1411

operates in a byte mode, every data byte received from the RS232 port generates eight time slots on the 1-

Wire bus.

The DS1411 is based on the DS2480B Serial 1-Wire Line Driver chip and therefore is not a plug-in

replacement for the DS1412 Serial Port Adapter. The RXD/ TXD Polarity Select input of the DS2480B is

tied to V
