Product Overview

OverviewOverview

Overview

RMS2-AI-IA3 acquisition module is a complete interface for your analog sensors, because it

allows to monitor and supervise analog devices whose output is 4-2 mA current loops or -

1 V voltage range. This device works in differential mode, which means that it measures the

difference between the absolute values of two signals.

3Configuration

RMS2-AI-IA3 configuration is done through a command console connecting the device to a

USB port on the PC.

To access the command console, you must connect the RMS2-AI-IA3 to a USB port on a PC

and you must install an Exemys serial terminal program, named

Exemys Console.

Download the USB driver:

http://www.exemys.com/rmsrmdriver

Download the Exemys Console:

http://www.exemys.com/console

Once the driver and the serial terminal program are installed, connect the RMS2-AI-IA3 to a

USB port on the PC and execute the

Exemys Console

1. Click on Connection -> USB, it will open a window with the description of all the

Exemys products with USB port. Select with double click the product you want to set.

2. Type CFG and press ENTER or press the CFG button. RMS2-AI-IA3 will display

welcome message on the configuration command console.
