ORDERING INFORMATION
DS1411-009# DS1411-S09# DB-9 Connector, with chip DB-9 Connector, chip
Denotes RoHS-compliant device that include lead(Pb) that exempt under RoHS requirements.
DS1411 sophisticated RS232-to-1-Wire® adapter iButton holder that performs RS232-level conversion actively generates 1-Wire communication signals. Together with adequate TMEX software driver enables IBM-compatible laptop computer directly read write non-EPROM iButton devices. DS1411 DS9098P retainer single MicroCan® replace DS9097U-009 DS9097U-S09, respectively, applications that only single iButton. 1-Wire communication supported adapter standard well Overdrive speed. serial port must support data transmission rate 9600 bits/s. Under software control, adapter RS232 data rates 19200, 57600 115200 bits second. higher rates recommended communication Overdrive speed with Overdrive capable devices. Since DS1411 operates byte mode, every data byte received from RS232 port generates eight time slots 1Wire bus. DS1411 based DS2480B Serial 1-Wire Line Driver chip therefore plug-in replacement DS1412 Serial Port Adapter. RXD/ Polarity Select input DS2480B tied (non-inverting).
