Latest Software Upgrade
We strongly recommend you upgrade to the latest production version of DecoderPro;
look at the online install pages
to run an immediate install.
If you are already running your SPROG II, we suggest that you only install JMRI DecoderPro to upgrade; you do not need to re-install the USB drivers.
Firmware Programming Files
Due to recurring problems encountered by people attempting to upgrade their SPROG II firmware themselves, the user updates were temporarily suspended.
Why should I consider upgrading?
Recent sound decoders place some different demands upon programmer behavior,
and the SPROG II firmware has been upgraded to support these needs.
If you are having problems programming sound decoders, then an upgrade may be the solution.
How do I know what firmware version my SPROG II has?
In DecoderPro 2.2 and later, select the SPROG menu, and then Console; if you are using an older version of DecoderPro,
open a command monitor window (from the SPROG II menu) with your SPROG II connected.
Open a Send Command window, and enter ?. Click the Send button (pressing Enter does nothing here).
You should see the firmware version reported in the command monitor, e.g., "SPROG II Ver 2.5".
The current firmware is version 2.6 (July 2009), or 1.8 if your SPROG II is "series 1" and has 1.x version numbers.
Contact us directly to arrange an upgrade.
