The following software options and drivers are available for communication with Alicat mass flow and pressure instruments.

FlowVision software

FlowVision was designed in-house for intuitive and feature-rich control of your process.

LabVIEW .vi drivers and stand-alone interfaces

Communicate with your device using virtual instrument (.vi) drivers and stand-alone interfaces based on the LabVIEW Run-Time Engine.

Configuration files for industrial protocols

Alicat devices are available with DeviceNet, Ethernet/IP, EtherCAT, Modbus RTU, Modbus TCP/IP, PROFIBUS, and PROFINET industrial protocols.

USB drivers

These USB drivers are used to create a virtual COM port on your computer for USB communication.

Serial Tools

Use these tools to communicate with or troubleshoot your device.

Note: Alicat devices work best over serial connections when the following settings are used:

  • Baud: 19200 (default – others can be used if the computer, software, and Alicat device are set for the same rate.)
  • Data bits: 8
  • Stop bits: 1
  • Parity: none
  • Flow control: none
Alicat Serial Terminal

Use this simple Serial Terminal application for command line access to your instruments. This allows you to query your instruments, command new setpoints, and read and write to the device registers. This application requires the Microsoft .NET Framework to run properly (usually pre-installed on your PC).

PuTTY Serial Terminal configuration

PuTTY is a commonly-used serial terminal program that you can use to communicate with your Alicat over RS-232 or RS-485.

Python setup and drivers

Alicat Python and Python-driven command prompt (Windows Powershell) drivers have been developed principally by Pat Fuller at NuMat Technologies.

Alicat Serial Address Dump

The Serial Address Dump application allows you to log the register configurations for any Alicat device. You can use this to record current settings before performing a major change or to compare current values to the initial values an instrument had when it was shipped from our factory. This application requires the Microsoft .NET Framework to run properly (usually pre-installed on your PC).

COM Port Troubleshooter

Are you having problems communicating with your Alicat devices? Not sure which port your controller is connected to? Our COM Port Troubleshooter application will help you verify that your device is working properly. This application requires the Microsoft .NET Framework to run properly (usually pre-installed on your PC).
