Abstract: LabVIEW™ is a graphical programming tool used in production and laboratory environments to collect data and supply control signals to monitor and control the environment it's monitoring. The DS3900 is an RS-232 to 2-wire interface which is designed to provide a hardware/firmware interface between a PC's serial port and any 2-wire device.
This application brief describes how to use LabVIEW, via a PC serial port to control a 2-wire interface. An interface to a DS1086 is given as an example. The brief also describes how to configure the LabVIEW graphical user interface (GUI) to communicate to the DS3900 serial port adapter. Examples are given on how to manipulate the register settings in a DS1086 low-EMI EconOscillator™. Flow charts showing the details on how to communicate to the DS1086 are provided.
The DS3900 serial port to 2-wire adapter is not a product intended for sale except in development kits offered by Dallas Semiconductor in support of 2-wire devices such as the DS1086. Although, written for the DS1086, this application note can be used to develop a LabVIEW-based interface to any Dallas or Maxim 2-wire devices.
