产品概述

The DS9097U-S09# is an Universal 1-wire Com Port Adapter, RS-232 to 1-wire adapter, which performs RS-232 level conversion and actively generates the 1-wire communication signal. Together with an adequate software driver, it enables a windows-based PC to directly communicate with any 1-wire device connected to the adapter RJ11 port. The DB9 version reads and writes any non-EPROM 1-wire device. To write to EPROM devices, the DB25 version with external power supply is required. To a list of suitable 1-wire network cable, all DS9097U adapters are based on the DS2480B serial 1-wire line driver chip. The RXD/TXD polarity select input of the DS2480B is connected to VDD.
  • True-ground interface to an RS232 com port for reading and writing 1-wire® devices
  • Works with bipolar as well as unipolar logic signals
  • Compatible to com port of (±)5V to (±)12V (DB-9 version only) or (±)6V to (±)12V (DB-25 version)
  • Supports reading and writing at regular and overdrive speeds
  • Provides strong pullup to 5V for Temperature-, Crypto- and EEPROM 1-wire devices
  • Programs 1-wire EPROM devices (db-25 version with external 12V power supply only)
  • Communicates at data rates of 9.6 (default), 19.2, 57.6 and 115.2kbps
  • Standard DB-9 or DB-25 female connector and 6-lead RJ-11 connector
