Firmware Upgrades
The 702T uses upgradable EEPROM (electrically erasable programmable read-only memory) to hold
the unit’s operating system software, or firmware. Firmware is the source code which controls all
aspects of the device, including: menu options, signal routing, signal processing, LED’s, button and
switches, and data ports.
Version Information
During manufacturing the unit’s hardware revision number and serial number are burned into
a protected area of the EEPROM and are not changeable. These numbers can be viewed from the
INFO:VERSION selection of the Setup Menu. INFO:VERSION also shows the firmware version of the
recorder.
The current firmware revision number is also displayed on the bottom right-hand corner of the
Sound Devices splash screen at boot up (v2.65+). The 702T firmware version and unit serial numbers
are written to the data chunk of every WAV audio file generated by the 702T.
Upgrading Firmware
From time to time Sound Devices may issue revisions (new versions) of firmware for the 702T. Firm-
ware is user-upgradeable. To upgrade firmware follow the steps below.
1. Download the firmware file from the Sound Devices web site.
2. Transfer the firmware file (it will be named VERSION _ NUMBER.PRG) to a CompactFlash card in the
702T via FireWire. If there are multiple firmware files on the media, the 702T will indicate the firmware
file listed to apply. To prevent confusion, ensure that there is only one firmware file available on either
702T media.
3. Enter the firmware upgrade menu. You will be prompted to search for the firmware file. If a valid
firmware file is present on the CF card the recorder will prompt if the path is the proper file to use. Press
the Rotary Switch or the tone button to say yes. The 702T will begin firmware upgrade and validation.
Progress is indicated with a bar graph.
4. When the upgrade and verify process is complete, power cycle the 702T. On power-up the LCD will
turn solid black and the green LED next to the FireWire port will blink 20 times. When the update se-
quence is complete, the 702T will reboot once again.
5. Verify the firmware version using the INFO:SOFTWARE menu.
6. Reset the time-of-day clock, time code generator, and verify any recording parameters.
7. It is best practice to download the latest user guide from the Sound Devices web site, since the changes
to functionality are documented.
Firmware upgrades usually preserve all user menu settings. However, save a snapshot of the settings to
a setup file on the CF. Once a firmware upgrade is complete, restore settings from this file, if necessary.
Some firmware updates may make changes to user setups; verify all user setups after an upgrade.
