Appendix C – System Restore and Power-Up Buttons
System Restore
The JSD-60 has several methods of recovering from an unlikely failure, which are detailed
below.
Bypass Mode
When the JSD-60 main power switch is off and the bypass power supply is plugged in,
independent bypass circuitry creates a mono sum of the selected analog or digital input audio
and routes it to the left and right outputs. A quick way of recovering from a system failure is to
turn the JSD-60 off.
Restore Factory Firmware
If a firmware update of the main (PIC) processer is interrupted, it is possible to leave the system
inoperable. To restore the factory installed firmware, turn off the JSD-60, then hold down
buttons 4 and 6 (Option and Non/Sync) while turning the power back on. The message
“Firmware Update Running” gets displayed and when completed the JSD-60 will restart with
the original firmware. The interrupted firmware update can then be repeated. This only
restores the PIC firmware, not the DSP or Front Panel firmware. Ensure the versions for each
are from the same code package.
Load Configuration from SD Card
The SD card is used as a "personality module" in the JSD-60. Should a JSD-60 be replaced, all the
saved settings from the old unit can be easily loaded in to the new unit without the use of a
computer. These settings were saved during the initial configuration using the SD Card Backup
button on the GUI. To restore the settings to a new JSD-60, insert the card from the old unit
(behind the removable cover on the rear panel) in the new unit. With the JSD-60 off, hold down
buttons 6 and 7 (Non/Sync and MIC) down while turning on the power. Continue to hold the
buttons about 30 seconds until the bypass LED stops flashing. The configuration will be loaded
and copied to the internal non-volatile memory. The JSD-60 is now configured the same as the
previous unit. The configuration data is written as a text file that can be opened using a text
editor like Note Pad. The file can also be opened with the GUI and then transferring the settings
to the connected unit, or just read to review settings.
Power-Up Buttons
The JSD-60 checks the state of front panel buttons during power up to determine if some
special action is required. During normal operation, no front panel buttons are down during
power up. The table below describes the response of the JSD-60 when buttons are held down
during power up.
