How to check firmware version on Congo Jr. console and 2x20 Master Playback Wing
Can I check the firmware version of the boards on my Congo Jr. products?
Yes. There are ways to bypass the normal CONGO Jr. logo displaying to show you information like Firmware Version.
How to get into the secret mode to display firmware
The following steps will show you how to access the secret mode that shows you information about the PCBs installed in your Congo Jr. product. This includes PCB revision as well as PIC IC firmware version.
Step one
Make sure your units are powered down.
Step two
PRESS and HOLD certain buttons while powering on. The Congo Jr. or wing will register these button presses and access the secret mode. Below are diagrams to show you which buttons to press and hold. Once the units power up in the secret mode, you can release the buttons. This information screen will remain until the console boots up.
