DESCRIPTION

The DS1411 is a sophisticated RS-232-to-1-Wire^®adapter and iButton holder that performs RS-232-level

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

driver, it enables a Windows^®-based PC to directly read all and write any non-EPROM iButton devices.

The DS1411 has a DS9098P retainer for a single F5 MicroCan. For a list of suitable 1-Wire network

cables, e.g., to connect multiple iButtons, refer to the Connectivity Matrix table in the DS1402x 1-Wire

network cables data sheet. 1-Wire communication is supported by the adapter for standard speed 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 RS-232 data rates of 19200bps, 57600bps, and 115200bps. 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 RS-232 port generates eight

time slots on the 1-Wire bus. The DS1411 is based on the DS2480B serial 1-Wire line driver chip. The

RXD/TXD polarity select input of the DS2480B is connected to V_DD(noninverting). Free software

drivers can be downloaded from www.maxim-ic.com/1-Wiredrivers.
