APPLICATION NOTE 213
Using a PC with a DS3900 to Communicate with DS1267s, DS1867s, and
DS1868s

Abstract: This application note describes how to use the DS3900 PC serial port to 3-wire interface to communicate with the
three digital pots, the DS1267, DS1867, and DS1868, which use this shift register interface for programming. The DS3900 is
a module that has a MAX3223 RS-232 transceiver and a microprocessor which acts as an interface between the PC's serial
port the 3-wire device being controlled. The transceiver allows the module’s microproces……
