DS9097U-009 Datasheet PDF - Maxim Integrated

●DESCRIPTION

●The DS9097U is a sophisticated RS-232 to 1-Wire adapter, which 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 communicate with any 1-Wire device connected to the adapter’s 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. For a list of suitable 1-Wire network cables, refer to the Connectivity Matrix table in the DS1402x 1-Wire network cables data sheet.
