The Update Firmware page allows the firmware in the two DSPs and the main processor (PIC) to be updated.
Firmware is usually delivered in a Software Package that includes new versions of the code for each DSP and
the main processor (PIC). We suggest making the updates in this order: DSP2, DSP1, PIC. Look at the versions
of each piece of code in the software package. If one of the versions is already installed in the JSD-100MA,
that portion of the JSD-100MA does not need to be updated. The currently installed firmware version is
shown on the Update button for each processor.
Select the device to be updated: DSP2, DSP1, or the main processor (PIC). Press the “Browse” button to select
the file to be downloaded to the JSD-100MA. Press the “Update” button. During the update, the front panel
LEDs on the JSD-100MA will flash. After an update of the main processor, the JSD-100MA will reset to start
executing the new code. The browser will disconnect at that time.
If a download of the PIC firmware to the JSD-100MA is interrupted, the JSD-100MA may be left inoperable. To
restore the original firmware, turn off the JSD-100MA, press buttons 4 and 6 on the front panel (Digital 16 and
User 2), then turn the power on while continuing to hold the buttons down until the front panel LEDs start
flashing. They will normally start flashing immediately, but it could take up to two minutes for them to start
flashing. When they stop flashing, the factory installed firmware has been restored, and the JSD-100MA will
restart. This only restores the PIC firmware, not the DSP firmware. Ensure the versions for each are from the
same code package.

JSDV-100 Remote Volume Control
The JSDV-100 remote volume control can be installed in an auditorium or other location. It is wired to the JSD-
100MA RS-485 using CAT-5 cable with an RJ 25 connector on each end. The JSDV-100 includes a two digit
seven segment display that shows the current output level. It also includes a fader control knob that can be
used to adjust the main fader level. After making an adjustment, the JSDV -100 display blanks in the number of
seconds specified under the global tab (as described above) unless the timeout is set to zero seconds. In that
case, the display is lit continuously.
When the JSDV -100 is first connected or the JSD-100MA is powered up, the JSD-100MA “discovers” the JSDV-
100 units on the RS-485. Each JSD-100MA supports up to 256 JSDV -100 units on its RS-485. As the devices are
discovered, their discovery is logged. Adjustments to the main fader level by a JSDV -100 are also logged,
including which JSDV-100 made the adjustment.
For further information on the installation of the JSDV-100, consult the instructions that are included with the
JSDV-100.
The image below from the web log shows discovery of a JSDV-100 and a fader adjustment.
