DESCRIPTION

The DS1411 is a sophisticated RS232 to 1-Wire TM adapter and iButton holder 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 or laptop computer to directly read all and write any non-EPROM iButton devices. The DS1411 has a DS9098 retainer for a single F5 MicroCan and can replace the DS9097U-009 in applications that use only a single iButton. Multiple iButtons can be connected using standard MicroLAN Cables and button holders (see DS1401 and DS1402x data sheets).

FEATURES

◾ Small size, true-ground interface to an RS232 COM Port for reading and writing iButton devices

◾ Works with bipolar logic signals of ± 5V to ± 12V (RS232C) as well as unipolar signals of 5V to 12V

◾ Supports reading and writing at regular and Overdrive speeds

◾ Provides strong pullup to 5V for Temperature iButton, Crypto iButton and EEPROM iButton

◾ Communicates at data rates of 9.6k (default), 19.2k, 57.6k and 115.2k bits/s

◾ Powered entirely from an RS232 interface

◾ Standard DB female connector for mating to the COM Port of a computer with DS9098 iButton Retainer for a single iButton or MicroLAN Cable (DS1402x)
