DS9097U - Maxim Integrated

DS9097U Universal 1-Wire COM Port Adapter

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-.
