Power up diagnostics
Europa’s onboard diagnostics are quite extensive – much more so than the original Roland code. An
NVRAM corruption on the Jupiter 6 can render the board useless with the Roland code! Europa is not
susceptible to crashing with a corrupt NVRAM and will repair it if corruption is found. Also, patches and
presets are stored in the Europa chip’s flash so it is not susceptible to losing patches if the controller
board’s battery fails.
When problems arise, Europa will display boot codes. Boot codes are identified by the board’s LEDs
being in the following state just after board powerup:
• All LEDs are off except…
• LFO

LFO 2’s Rate LED is blinking or other bender board LEDs are lit
• Only LEDs on the BANK

Figure 3 – Boot code A-2 shown on bootup
Some boot codes are fatal and the board will not boot, and others are purely informational. All boot codes
are indicative of a problem. With recoverable boot codes, pressing a key or a button on the front panel
will cause the Jupiter 6 to continue booting. Fatal boot codes will cause the board to hang, since they
indicate a problem that prevents Europa’s operation.
Diagnostic information is not particularly useful to an end user of Europa, but is extremely valuable to
the technician who is diagnosing or repairing a malfunctioning Europa enhanced Jupiter 6. While the A

A group of boot codes indicates unrecoverable component diagnostic failures in either the Europa
chip itself or the scratch RAM chip on the controller board. They are not recoverable, and Europa will not
run:

1 Internal CPU RAM failure. This is a failure of the Europa chip itself. If the Europa is still
under warranty, contact Synthcom Systems, Inc. to arrange a replacement.

2 Scratch RAM failure. This failure occurs when Europa cannot get reliable data storage on
the scratch RAM chip on the Jupiter 6’s controller board. Either the scratch RAM chip
itself is bad or the interconnecting circuitry is making communication with it unreliable.
This is not a failure with the Europa chip! If this occurs directly after a Europa installation,
look for solder bridges or unintentionally cut traces.
