idChamp RS3x Setup Android with RS3 NFC Setup

This post shows how to use RS3 NFC Setup Android app to load an hwg+ file to the idChamp RS3x. If you do not have access to an Android device, you can also setup the idChamp RS3x with the RS3 NFC Setup application for iOS or pcProx configuration utility for Windows.

See this page for DIP switch settings.

Connect RS3x using RS3 NFC Setup App

1. If you have not already done so, download the “RS3 NFC Setup” App from the Google Play.

2. Power on your RS3x.

3. Launch the RS3 NFC Setup App.

3. Tap on the “Options” icon, then tap on “Select Device.”

4. Tap on your idChamp RS3x when it is discovered. Name has the format “RS3-XXXX.”

Once connected the RS3x LEDs should blink rapid as it reads settings. It may take up to a minute to load your RS3x settings.

5. Once connected, you will see “Connected” in green lettering below “RS3 Setup.” 

Configure the idChamp RS3x

The RS3 NFC Setup application for Android has four main tabs; “Device Info,” “Data Format,” “Timing,” and “Delimeters.” 

Notice the drop-down menu labeled “NFC 1” to the immediate right of “RS3 Setup.” Here is where you can switch between the four RFID/NFC engine profiles of the RS3x. Each one is configured separately. For this tutorial, we will only be configuring NFC Engine #1, but the method to configure Engine #2 is identical. To navigate through each page, swipe from one far end of the screen to the other. For example, to get from the “Device Info” page to the “Data Format” page, you need to swipe from the far right edge of the screen to the far left edge of the screen.

Device Info

The “Device Info” page is the first page you will see after connecting your RS3x to the RS3 NFC Setup application.

Here you can:

    • Select the NFC Engine you want to configure

    • Adjust the card/tag type (Card Type)

    • View your RS3x information 

Data Format

The “Data Format” page allows you to adjust various formatting settings for the card/tag’s data.

Here you can:

    •  Adjust the “FAC” format

    •  Adjust the card “ID” format

    •  Specify the card/tag’s bit count

    •  Toggle the use of Wiegand bits

    •  Toggle precision math for HEX-decimal conversion

    •  And more!


The “Timing” page allows you to:

 Specify the number of miliseconds you want the RS3x to hold data for before accepting data again
 Toggle “Continuous Read Mode”


The “Delimiters” page allows you to adjust set delimiters for your data.

Here you can:

    • Set character delimiters

    • Set prefixes and suffixes

    • Set card gone delimiters

    • Set FAC/ID delimiters

    • Set the termination keystroke

    •  And more!

Save Your Configuration

To save the settings you adjusted, tap on the “CMD” icon at the top right of the screen. If you want to also save the settings to a file so that you can load the configuration onto another idChamp RS3, follow the instructions below.

Save Your Configuration to a File

1. Make sure you have saved your configuration by tapping the “CMD” icon at the top of the screen.

2. Tap on the “Options” icon to the immediate right of the “CMD” icon.

3. Select “Save to .hwg+ file.”

4. Navigate to a location where you can access the file later (or transfer to a PC/cloud service).

Test Your Configuration

Once you have selected the card or tag type you will be working with (Configuration tab) and adjusted the settings for processing the data, you will want to use a few sample cards to test the configuration. If the card is read, but doesn’t show up in the “Scans” section (or if it is not read at all), double-check your configurations. If you are absolutely sure that your settings are correct and you are still experiencing a problem, email the Serialio support team. Make sure to include your order number, card type, screenshots of the configurations and any other relevant information.

1. Make sure you have applied all settings you adjusted.

2. Hold your card/tag up to the idChamp RS3x until you hear a beep indicating that the card was read.

3. You can find the scan data in the “Output test area” of the RS3 NFC Setup App.
