SpringCard CSB6 Family is a group of contactless smartcard readers, offering various functions and three different operating modes : PC/SC (CCID), Legacy (virtual communication port), RFID scanner (keyboard emulation). All these products share a common hardware platform, based on the same microcontroller. This document explains how to upgrade the firmware, using the flash upgrade software provided by the manufacturer of the microcontroller.

At the date of writing, this document refers to the four products in the CSB6 Family :

  • CSB6,
  • Prox’N’Roll (all version),
  • CrazyWriter,
  • EasyFinger.

Please read the datasheet of every product for specifications and the detailed list of features.

Getting started

The microcontroller used by SpringCard CSB6 Family is Renesas H8S/2212UF. This microcontroller is upgradeable on the field, through its USB link, thanks to the software 'Flash Development Toolkit' (FDT) version 4 or newer, provided by Renesas.

FDT works on 32-bit versions of Windows 2000/XP/Vista/7. You can't use in on a 64-bit machine. There's no equivalent tool for other operating systems.

Locate and download the firmware for your device

PC/SC (and Legacy)

The firmware files for PC/SC (and Legacy) products are located under https://files.springcard.com/firmwares/springprox/. The subdirectories are named after the version (for instance https://files.springcard.com/firmwares/springprox/1-70 stores all the firmware in the 1.70 branch).

In the subdirectories, the files targeting this family of products are named 2212_rc632_(product name and code)_(product version).mot. Always check that the product name and code field matches the product you actually have.

RFID Scanner

The firmware files for RFID Scanner products are located under https://files.springcard.com/firmwares/iwm2_scan/. The subdirectories are named after the version (for instance https://files.springcard.com/firmwares/iwm2_scan/1-40 stores all the firmware in the 1.40 branch).

Put the device in flash upgrade mode

Every product in the CSB6 Family has either a switch or a push-button to go to the firmware upgrade mode.

All products but Prox'N'Roll

CSB6, CrazyWriter and EasyFinger have 4 configuration switches. Switch number 2 is devoted to firmware upgrade.

Unplug your device.

Open the casing (CSB6 and EasyFinger: there are a few PZ3 screws to unscrew).

Note the current position of the switches.

Move all the switches to ON.

4 switchs ON

Plug the device to the computer's USB port again. For EasyFinbger, plug the external power supply as well.

The device is now enumerated as an "USB Direct" device and handled by the driver that has been installed together with FDT.

Prox'N'Roll (prior to version EAN8I9P-FD)


The top sticker (lexan) must be removed in order to unscrew the cover, before being able to access the firmware upgrade switch. As the sticker is glued, this is likely to destroy it. Please contact our sales team should you need to buy spare stickers.

You'll have to insert a sharp blade (cutter) under the sticker to remove it. PLEASE BE CAREFUL NOT TO GET HURT.

Opening Tools

Unplug your Prox’N’Roll.
