SETUP AND INSTALLATION
DS9090K 1-Wire Memory Evaluation Kit
Hardware Installation
Connect the DS9097U-E25 1-Wire adapter to the computer's serial port. If the computer does not have a 25-pin
serial port, a 9-pin to 25-pin serial port converter may be necessary. These are typically available at computer or
electronic stores.
To program DS250x EPROM devices a 12V DC power adapter or other +12V supply is needed. This is plugged
into the 2.1mm power jack on the DS9097U-E25 adapter. These are available at most electronic supply stores.
See the DS9097U-E25's Data Sheet for power-supply specifications, recommended power supply models and the
polarity requirements of the 2.1mm power jack. Note that non-EPROM devices cannot be inserted in the evaluation
board when programming EPROM devices. The 12-volt programming pulse that is seen on the 1-Wire bus during
programming of EPROM devices will damage non-EPROM devices.
Insert the 1-Wire chip of interest into one of the evaluation board sockets. See pictures below showing proper chip
insertion/orientation.
