DS9097/DS9097E
The DS9097E is an upgraded version of the DS9097 that is capable of supplying the 12 volts necessary to
program the EPROM-based iButton products (DS198x Add-Only iButtons) in addition to reading and
writing SRAM and EEPROM-based devices (DS199x, DS196x, DS197x). When combined with the
appropriate software, the DS9097E can be used in a standalone mode where all of the programming
current is supplied by the serial port itself. In this configuration, the maximum number of EPROM bits
that can be programmed simultaneously is four on a typical serial port. For higher performance, the above
mentioned 12V auxiliary supply can be plugged into the power jack on the DS9097E and with proper
software enable the serial port to program up to eight EPROM bits simultaneously.
