DS9097U-S09# (MAXIM INTEGRATED PRODUCTS)

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.
