an LCR mix or delivered by AES/EBU channel 7. Since not all content (especially trailers) has HI on AES/EBU channel
7 and that channel is used for main sound in 7.1 auditoriums, the use of an LCR mix is suggested. The default
settings load the mixer coefficients in this manner.
8.10.7 Software Update Tab
The firmware in the main board, front panel, and digital signal processor in the JSD-60 can be updated through the
GUI, over Ethernet or USB. The current firmware versions running can be viewed in the Summary tab in the
Component Information group and on the right side in the Software Update tab. The left side of the software
update tab contains the controls for firmware updating.
Firmware is usually delivered in a Software Package that includes new versions of the code for the all the
processors. The suggested order for updating is: Main Board, Front Panel, DSP. Look at the versions of each item
of code in the software package. If one of the versions is already installed in the JSD-60, that item need not be
updated.
Select the device to be updated: Main board PIC, digital signal processor (DSP), or front panel. Press the Browse
button to select the file to be downloaded to the JSD-60. Press the Download button. During the download, the
front panel will indicate that the unit is Updating Firmware on the JSD-60 display. After a download of the PIC (the
main processor), the JSD-60 will reset to start executing the new code. The GUI will disconnect at that time. If
connected via a USB, the cable will need to be unplugged and plugged back into the unit to restart an instance of
the USB device driver.
PIC Firmware Restore
If a download of the PIC firmware to the JSD-60 is interrupted, the JSD-60 may be left inoperable. To restore the
original firmware, turn off the JSD-60, press buttons 4 (Option) and 6 (Non/Sync) on the front, then turn the power
on while continuing to hold the buttons down. The display will show "Firmware update running" during the
firmware restore. When the restore is completed, the JSD-60 will restart. Note that this restore operation only
restores the main processor, not the front panel processor or DSP. Failed updates of the front panel or DSP can be
repeated using the GUI without the need to use this restore procedure. Ensure that firmware versions for each
processor are from the same code package.
8.10.8 Logging Tab
The JSD-60 includes extensive logging. The left side of the screen shows the GUI log. It shows GUI activity, such as
connections to JSD-60 units. The right side of the screen shows the Unit Log for the specific JSD-60.
