How to set up the idChamp RS3 on Windows via a cabled connection with pcProx Configuration Utility

This page serves as a complete guide on how to use RFIDeas pcProx Configuration Utility for Windows to configure the idChamp RS3 (or the idChamp RS4).

You will need the following for this tutorial:

Prepare the RS3 for pcProx

Set the idChamp RS3's DIP switches for RS-232 communication (see image below). 

Plug the RS3 into the Windows PC via the two configuration cables mentioned at the top of this page.

Connect the RS3 to pcProx

Launch the pcProx utility.

From the "Connect" tab, select "Use COM ports..."

Click on the "Connect" button.

Configure the RS3 via pcProx

Engine Configurations

The idChamp RS3 has a dual engine. At the top of the pcProx utility, you can select the engine you wish to configure.

The drop-down next to the engine selection is where you can set the card/tag standard/type.

Data Formatting

Switch to the "Format" tab to adjust how the RS3 will output data.

The "Data Format" tab (within the "Format" tab) is where you can set the basic formatting options.


Switch to the "Delimiters" tab (within the "Format" tab).

Here you can set the delimiters for the data read by the RS3, including the pre-data delimiters, FAC/ID delimiter, post data delimiters, termination keystroke and card gone delimiters.

To select a keystroke for any of the delimiters, click on the keyboard icon.

Select a function key (e.g. Shift, Ctrl, etc.) and an alpha-numeric key (e.g. 1, e, 0, etc.) or a symbol/punctuation key (e.g. -, +, etc.).

After selecting the desired keystroke(s), click on "INSERT."

You will see your selected keystroke(s) below the keyboard icon you clicked on.

Write the Configuration to the RS3

Once you've made all the desired adjustments, click "Write Active" (located at the top of the pcProx utility).

This will write the current configuration of pcProx to the RS3's memory.

Afterward, you can test the configuration with your cards/tag via the "Output test area" section.

Test Your Configuration

To test a card or tag's output, place your cursor in the green text box and hold the card/tag above the RS3. The output will be displayed in the green text box.

Save Your Configuration for Redistribution

Once you have a configuration that you know works with your tags and/or cards, you can save the configuration to a file so that it can be loaded onto other idChamp™ RS3 scanners.

First, make sure that you have written the active configuration to the RS3 via the "Write Active" button. Then, click on "File" → "Save device data to hwg+ file."

To later load the same file onto another RS3, click on "File" → "Open hwg/hwg+ file..."

Navigate to the saved hwg+ file location.

Once the file's configuration is loaded, click "Write Active."

The hwg+ file configuration is now saved to the RS3.
